Term
What is random mating? Why would you want to use it?
Definition
Random mating means that mating of selected breeding tock is not controlled. Selected females and males are kept together and allowed to mate at random. This is practical if the breeder has no knowledge that certain controlled matings might produce better offspring and it requires less labor
Term
What is inbreeding? Why would you use it?
Definition
Inbreeding is mating relatives within a breed. Nearly all purebred animals are inbred to some degree. Livestock raisers usually inbreed to concentrate the good genes known to be present in a superior animal or family into certain future offspring.
Term
What is line breeding? Why would you use it?
Definition
Line breeding is a form of inbreeding in which animals are mated so their offspring retain a high relationship to an outstanding individual. It increases homozygosity but through less intense inbreeding
Term
What is out-breeding? Why do we use it?
Definition
Out-breeding is the mating of animals that are relatively unrelated, usually with diverse type or production traits. You can have species crossing and out crossing
Term
What is out crossing? What do we use it?
Definition
Out-Crossing is when animals to be mated are less related than the average of the breed, generally unrelated for 4-6 generations. Out-crossing may be a temporary interruption in an inbreeding program, practiced when the breeder feels the line being developed lacks in a certain trait and that an out-cross with another line would provide the desired trait.
Term
What is cross-breeding? Why do we use it?
Definition
Cross breeding is the mating of animals of two different breeds. Cross bred animals tend to be more vigorous at ad soon after birth and more resistant to environmental stresses, so they tend to gain faster, and are ore prolific when it is their time to reproduce, than the average of their parents.
Term
What is Heterosis?

Definition
The White Plymouth Rock Breed
Term
What breed of bird is considered to be the standard of commercial egg producing stock? Why?
Definition
The Leghorn is considered to be the standard of commercial egg producing stock. Its small size, early sexual maturity, and high egg production incorporated into lines or strains permit production that is efficient in terms of feed, time, and space. Also their egg shells are white and are preferred by most consumers.
Term
What are three key points that a prospective breeder should carefully consider in the consensus of geneticists?
Definition
1. All breeds have both strong and weak points

2. No one breed is best for all important characteristics under all conditions

3. Much hereditary variation exists in all breeds

What should the prospective breeder do before breeding?
Definition
1. Determine the prevailing and most productive breed (s) in his or her geographical area

2. Study market demand for animals of different breeds and relate these to potential productivity and profitability

3. Consider other breeds that may be stronger in certain economically important traits than the prevailing breeds in the area
Term
What is the goal of commercial cow calf operations?
Definition
The goal is the production of feeder calves. The investment required for land and cows is high relative to the value of the calves at market time.
Term
At what age are most feeder calves offered for sale?
Definition
Most feeder calves are offered for sale in the spring and fall, having been born 6-8 months earlier.
Term
How big are the number of beef cow operations compared to the actual number of cows in that operation?
Definition
Beef cow herd in the United States can be characterized as large in the number of operations but rather small in the number of cows per operation.
Term
In what states, are the beef cow numbers the highest?
Definition
Beef cow numbers are the highest in the Southwest and Great plains region. The top 5 beef cow producers are 1. Texas, 2. Missouri, 3. Nebraska, 4. Oklahoma, and 5 is South Dakota
Term
What are the 5 major regions of beef cow production in the United States? Why are they successful?
Definition
The top 5 major regions of beef cow production are the Southern United States, The north Central region, he Southwest, the Great Plains and the Western States. They are successful because the feeder producing areas are abundant and relatively inexpensive source of forage.
Term
Why is the Southern Plains and western Corn Belt considered the center of the commercial cattle feeding industry?
Definition
This region has characteristics that permit good feeding enterprises and good animal performance: amply supply of feed grains, abundant forages, and semiarid climate. With these characteristics and the advantages of large volume feed, cost of production can be lower than many smaller farmer feed lots.
Term
What is ranching?
Definition
Ranching is considered a larger operation whereas farming comprises a smaller acreage and usually smaller numbers of cattle. Ranching is more common in the West and on the Plains.
Term
What is required for a profitable cow-calf operation?
Definition
Excellence in genetics, reproduction, nutrition, herd health and close and timely management.
Term
What are some goals for profitability of a cow-calf operation?
Definition
1. High Conception Rates: 95 Percent

2. Percent of Calves weaned: 95 %

3. High Production efficiency: low variable and fixed costs

4. High-grade calves: top market Prices
Term
What are Stocker Cattle? Why would farmers use this system?
Definition
It is when farmers and ranchers in the business of producing feeders do not maintain a cow herd but rather purchase weaned calves weighing 400-500 pounds and grow them on grass and cheap roughage until they weigh 700-800 pounds. These stockers then are sold as heavy feeders to be finished on a high gain ration. This specialize system avoids the management of a cow herd and requires less labor, but carries higher financial risks.
Term
What supplemental feed is usually required during the grazing season for cattle?
Definition
Salt and mineral mixes.
Term
When should all cows conceive by? What are they fed?
Definition
Cows need to be bred and all conceive within a 60 day breeding season so the valves will be born early (assuming early spring calving). The cow will more likely be on lush grass during lactation and produce heavier calves at weaning
Term
What are the advantages of fall calving?
Definition
Fall calving has certain advantages such as: low labor and housing requirements at calving time and the calf is large enough by spring to utilize grass effective.
Term
In period 1, the first 82 days after calving, what are the beef cows nutritional needs?
Definition
The cow is lactating heavily, undergoing uterine involution, and preparing for rebreeding. Her nutrient needs are the highest of they year. Because the calf receives most of its nutrients from milk during this period, adequate energy and protein for the cows are essential to permit adequate milk production and calf growth. Lactating cows should receive sufficient protein from young forage, but additional energy may need to be provided from supplemental grain feeding.
Term
What is happening during period two in the beef cow? What are her nutritional requirements?
Definition
During period 2, the cow is in the early stage of pregnancy and still lactating. Assuming she calved in the spring, she should be gaining weight to prepare for the coming winter. Over time, the calf will depend less on milk and consume more grass. Normally the cow is on grass and no supplemental feed is required unless a drought or unusual situation exists.
Term
What is happening during period 3 in the beef cow? What are her nutritional needs?
Definition
In period 3, the calf normally is weaned and the cow is in mid-gestation. She only needs to maintain herself and provide nutrients for the developing fetus. Nutritional needs are lowest, in terms of volume, during this period, and lower quality forages can be fed during this time.
Term
What is happening during late gestation? What are the beef cows nutritional needs?
Definition
During late gestations, or about 50 days prepartum, is considered the second most important period; the cow is preparing for lactation, and this is the time during which 70-80 percent of the toal fetal growth occurs. As a guide, any underconditions cows should receive sufficient nutrients to be gaining weight.
Term
Why is monitoring cows for body condition used? Explain the scoring system
Definition
Monitoring cows for body condition has become more widely used as a tool to reduce the incidence of extremely under or over conditioned cows. Cows are visually evaluated early in and through pregnancy, with emaciated cows receiving a score of 1 and obese cows a score of 9. A well fleshed but not over-conditioned beef cow will score a 4, 5, or 6 and gives to heavier calves.
Term
When are calves usually weaned?
Definition
Calves are normally weaned 6-8 months after birth. In general, 205 days is a weaning age target used by many in the industry.
Term
What is preconditioning and why is it important?
Definition
Negative effects of the stresses from weaning can be minimized if the calves have been fully preconditioned 30-45 days before weaning. Preconditioning might include 1. Castration and dehorning if needed; 2. Worming; 3. Treatment for grubs; 4. Implanting with a growth stimulant; 5. Bovine virus diarrhea, bovine respiratory syncytial virus, leptospirosis, pasturella infection, and black leg; and 6. Adapting to a feedlot finishing ration.
Term
What are feeder cattle?
Definition
Feeder cattle are fast growing calves, which are relatively heavy at weaning. They will go directly from the producer to the feedlot. They may weigh 600 pounds at weaning and have the genetic capacity to gain rapidly to a finished weight of 1,000 to 1,200 pounds.
Term
What are backgrounded calves and what are their benefits?
Definition
Calves that are light at weaning, 400-500 pounds. Backgrounding consists of feeding a growing ration to calves to weights of 650-700 pounds, a weight range better suited for the finishing feed lot. Backgrounding provides the opportunity to feed homegrown feeds, take advantage of winter labor, and benefit from increased income through efficient weight gains made during this period.
Term
Why are two breed and three breed rotational crosses becoming increasingly popular?
Definition
Because they provide heterosis in the replacement heifer that joins the cow herd which allows for more rapid growth and milk production from that animal.
Term
What happens in the two breed rotational crossbreeding program?
Definition
1. Bulls of two breeds are maintained and each is mated to cows of the opposite breed.
2. The offspring heifers are saved fro breeding and then mated to a bull of the breed opposite that of the heifers sire.
Term
What would the birth weight, weaning weight, yearling weight, and gain of pounds/day be on a bull with an excellent performance record?
Definition
A bull having a birth weight of 70-90 pounds, a weaning weight of 600 pounds or more at 205 days, a yearling weight of 1,100 or more, and gaining 3.5 pounds daily or more on test would be considered to have an excellent performance record. Such bulls usually sell for a premium and should sire vigorous and rapidly growing calves.
Term
What factors can be contributed to the steady decline of sheep and lamb inventory over the years?
Definition
Several factors that have contributed to this decline are: low per capita meat demand, availability and price of artificial fibers to replace wool, problems with predators, labor availability and cost, and a decreasing processing and marketing infrastructure.
Term
What are the top 5 states for breeding sheep and replacement lambs?
Definition
1. Texas, 2. Wyoming, 3. California, 4. Utah, 5. Montana.
Term
In what type of range areas are sheep better suited for cattle?
Definition
Sheep are better suited than cattle for those range areas that have less grass and more brush and shrubs because sheep better utilize some of those latter plant species.
Term
When are most range lambs usually sold? Where do the range operators finish their lambs?
Definition
Most range lambs are sold following weaning, for slaughter if summer range conditions have provided adequate nutrition, or for feeding. Because of the lack of available grains, range operators seldom Finnish their lambs in dry-lot. Almost 49 % of all sheep marketed in 1999 were in predominantly feedlot states; California, Texas, and Colorado.
Term
Because grains are in greater supply, what type of feeding program do farmers start their lambs on at a young age? When are the lambs usually put up for market?
Definition
Because grains are in greater supply, most producers start lambs on a creep feeding program at a young age and market a finished lamb at 3-5 months of age. Many will be marketed at 110 pounds at about 130 days of age. Few lambs from these flocks are sold as feeders.
Term
When are Ewe flocks generally on pasture? What do they do the rest of their time?
Definition
Ewe flocks are generally on pasture 4-8 months each year and during the remaining time utilize forage crop residue or are in dry lot.
Term
What are the main factors affecting the profitability of the Ewe flock?
Definition
The main factors affecting profitability of the Ewe flock are: weaning percentage, death loss, age at culling, and production costs.
Term
What are the production goals that ensure high returns per ewe?
Definition
High conception rates: 95% , high lambing percentages: 175%, low lamb mortality: 10 % or less, a strong marketing program, high quality and yield of wool, longevity of breeding stock,
Term
What takes up 60 percent of the total costs of a sheep operation?
Definition
Feed Costs
Term
When is the Ewe expected to lose 5-7 percent of her body weight? When is she expected to regain it?
Definition
The ewe can be expected to lose 5-7 percent of her body weight due to lactation demands and regain weight and body condition during late gestation.
Term
What are Ewe breeds?
Definition
Ewe breeds are generally white faced sheep that produce the finer wool. Examples of Ewe breeds are the Merino and Ramboillet. These breeds are adapted to range conditions and have high reproductive efficiency, wool production, milking ability, and longevity. Replacement ewes, both in range areas and for some farm flocks, generally are selected from these breeds or from crosses involving these breeds.
Term
What is the accelerated lambing program?
Definition
This program involves ewes lambing more frequently than once each year, thereby providing a more uniform supply of lambs throughout the year. It allows the manager to take advantage of producing lambs during months when feed is more abundant and cheaper, and marketing when prices are higher. Accelerated lambing requires prolific ewes that can breed successfully at any season of the year.
Term
What does synchronization of estrus allow for?
Definition
Synchronization of estrus can be used to stimulate ewes to initiate the estrous cycle outside of the normal breeding season.
Term
What are Ram breeds?
Definition
Ram breeds tend to be of the meat type and are selected largely on growth rate, efficiency of gains, and carcass quality
Term
What are some problems in sheep management?
Definition
Predator control is a major problem. The coyote is the most costly predator in the western and plain states. External parasites, the availability of experienced and trained personnel is a limiting factor in both range and large confinement enterprises. Lastly, lamb death losses of approximately 15-20 percent are not uncommon in the industry. More intensified sheep enterprises can result in an increase in the occurrence of respiratory diseases, enterotoxemia, and also reproduction diseases that may affect the survivability of embryos or lambs at birth.
Term
When are feeder lambs sold for market? When are large framed lambs sold for slaughter?
Definition
Feeder lambs are sold at 60-75 pounds directly to feeders or through dealers or auctions. Large framed lambs are sold for slaughter at 110-130 pounds.
Term
What does dairy production involve?
Definition
Dairy production is a long term and a relatively high investment business. A milk producer seeks a monetary return for labor, capital, feed, management ability, and the risk assumed.
Term
What has happened to the number of cows and farms throughout the years?
Definition
The number of cows per farm and the productivity per cow have increased dramatically, while the number of farms has decreased
Term

Definition
Today DHI herds produce an average of over 22,700 pounds of milk per lactation per cow.
Term
What is the component pricing system?
Definition
It is a system in which payments for both fluid and manufacturing milk are determined according to pounds of protein, butterfat, and other solids.
Term
Due to the high energy requirement for dairy cows, what types of foods are they feed?
Definition
Both grain and high quality forage.
Term
How does climate affect dairy cattle? What can be done to prevent some of these effects?
Definition
All popular breeds of dairy cattle adapt well to cold weather. However, temperatures over 85 degrees for several days, with high humidity, will decrease feed consumption and milk production. These effects can be minimized by good management, including shade, and in the case of confinement unites, air movement and even sprinklers.
Term
What are two things that must accompany the decision to milk cows?
Definition
1. the intention of dairying for a span of years
2. A decision to milk enough cows and produce enough milk to be efficient
Term
Why is forage important in a cows diet? What kind of forages are fed to the cow?
Definition
Forage, such as pasture, hay, silage, and freshly chopped forage, is the foundation of most feeding systems for cows. Forage must be of high quality for maximum consumption and milk production. There is a limit to the capacity of a cows digestive system. If forage is low in quality, a cow eats less, and the amount eaten is not efficiently digested.
Term
What is intensive grazing and why may it be beneficial?
Definition
Intensive grazing is where cows are restricted to a strip of pasture sufficient for one or a few days. It makes excellent use of forage and can be practical with a smaller herd that is part of a general farming operation. Confining the cows to dry lot and feeing in the pasture forage freshly chopped also allows more efficient use of the forage, but cost of chopping and hauling, and weather problems, must be considered to determine if the practice is feasible.
Term
What age should heifers enter the milking herd?
Definition
Heifers should enter the milking herd between 22 and 24 months of age.
Term
If dairy bulls are kept to maturity what do they do with them? What are most bull calves fed to produce?
Definition
The dairy bulls that are raised to maturity are used for artificial insemination or for natural service. Most bull calves are fed to produce veal or are further grown and fed for beef.
Term
What kind of diet are veal calves raised on? What age do veal calves go to market?
Definition
Most veal calves are raised on an all milk replacer diet under very controlled management conditions to about 350-420 pounds. They grow quite rapidly, reaching market weight within about 12-16 weeks of age. Most veal commands a premium price, well above beef prices, because of its tender meat.
Term
As with feeding for veal, Why are calves of the heavier breeds (holstein, Brown Swiss) more likely to be profitable when raised for prolonged feeding?
Definition
Holstein and Brown Swiss calves are of the heavier breeds and are more likely to be profitable when raised for prolonged feeding. These large type cattle gain fast, utilize roughage effectively and usually put on low cost gains. The carcasses are more angular and carry less marbling than carcasses from beef animals, but they do yield a high proportion of lean meat.
Term
What are some important areas of herd management?
Definition
1. Selecting for desired production and structural soundness, especially the udder and the feed and legs.
2. Maintaining excellence in reproductive and overall herd health to achieve a 12.5 to 13 month calving interval
3. Feeding according to milk production and body condition
4. Using records for herd management and decision making.
5. Providing proper housing for comfort and cleanliness of the cow
6. Using proper milking procedures that ensure high quality milk and a healthy udder.

What are High Producing cows expected to consume in terms of their:

-The % of theri body weight in bounds of dry matter

-

Definition
High producing cows can be expected to consum 3.8-4.0 percent of theri body weight in pounds of dry matter daily.
Term
Why do dairy farmers use body condition scoring as a management tool?
Definition

Because Fat covering is an excellent indicator of the amount of stored energy in dairy cows. For instance:

Excessively Fat Cows: are more apt to have calving difficulty and often have sluggish apetites after calving

Cows with insufficient body reserves: produce less milk and are more prone to metabolic disorders and impaired reproductive performance. 

 

*Therefore, body condition scoring is helpful in determining when to move cows into other production groups or to provide special attention to particular cows.  

Term
How does the Numerical System work in terms of scoring Dairy Cows?
Definition

It scores dairy cows from 0-5 with half scores in between whole numbers. 

0=Extremely Emaciated

5=very fat

 

-These scores are based primarily on observance and feel of fat covering around the tailhead and rump area.

Term
For the numerical system to be effective when should dairy cows be scored?
Definition
Dairy cows should be scored at calving time, peak production, mid-lactation, and when ready for the non-lactating (dry) period.
Term
Why are records necessary in the dairy herd?
Definition
They Present:
-The present performance of the dairy herd
-establish attainable performance goals
-and help to decide how to reach these goals 
Term
What is the official Dairy Herd Improvement?
Definition
It is a public records system.  Dairy herds are enrolled in this program through state dairy associations and sponsorship by USDA and state extension services. 
Term
What does the Dair Herd Improvement do?
Definition
For most official DHI programs, a trained supervisor checks each farm monthly to obtain milk yields and samples from each cow.  Samples are sent to a central milk testing laboratory, generally within the state, where each sample is analyzed for protein, fat, and somatic cell content.  These results, and other herd information, are compiled in a computer and usually are teleprocesses to one of the nine Dairy Records Processing Centers located in the United States. 
Term
What kind of valuable mangement information does the monthly DHI reports provide the herd manager?
Definition
1. Production, income, and feed cost summary
2. Current breeding and reproductive summaries
3. The rolling yearly herd average for milk, fat, and protein yield. 
Term
What is the Predicted Producing Ability and Why is it useful?
Definition
The Predicted Producing Ability ranks each cow in he herd according to her expected deviation from herdmates; it is best used to determine the most productive cows in the next lactation.
Term
What is the Predicted Transmitting Ability and why is it useful?
Definition
The Predicted Transmitting ability is the best indicator of a cow's transmitting ability, and both production and pedigree information are considered in its calculation
Term
What percentage of the beef consumed in the United States comes from animals that are primarily of dairy breeding?  Why would farmers do this?
Definition
It is estimated that 15-20 percent of the beef consumed in the United States comes from animals that are primarily of dairy breeding.  The marketing of cull cows for beef provides from 5-10 percent of the gross retursn to the dairy producer
Term

Term
What are some common problems in goats?
Definition
1. Coccidiosis is a comon problem in wet and unclean housing
2. Caprine Arthritis and encephalitis is the gretes cause of animal and milk loss
Term
What is Free Stall Housing?
Definition
It is a common system for housing that allow the cow to enter freely, lie down, and leave, but not turn around.  Cows step up from an alley behind the stalls, and if properly designed, the cows position ensure that urine and feces will drop into the alley.  These and any wet bedding are removed at least daily with scraping vehicles, automatic scrapers, or by flushing with water.
Term
What is a Milking Parlor?
Definition
A milking parlor is a special facility in which cows, goats, or sheep are milked. 
Term
What are Modern tie-stall barns?
Definition
They generally house two rows of 30-45 cows.  Most are arranged so cows face outward, with a central alley behind and a feed alley in front of the cows.  Each cow is provided an individual stall and quickly learns to select her stall when entering the barn.  Each cow receives her individual feed allowance so feed intake can be better controlled, and cows can receive more individual attention.  Milking in tie stalls is more strenuous then milking parlors
Term
Name the three classes of milk and give descriptions for each.
Definition
Class 1: The highest price class including; whole, low fat, skim, and flavored milk, milk drinks, and buttermilk. Grade A milk that is used in manufactured products is placed in one or two lower price classes
Class II: includes frozen deserts, cottage cheese, and cream.
Class III: includes frozen desserts, cottage cheese, and cream.  It includes milk used for buter and cheese, in most cases. 
 
*The quality of the milk is no different; the proportion placed in each class is simply dependent on the amount that can be used for class I purposes, then for class II purposes
 
Term
In what season is milk production slightly higher?
Definition
It is higher in the spring.
Term
What is cwt?
Definition
Milk prices paid to producers are usually quoted on a hundredweight (cwt) basis. 
Term
How is the average price per cwt that a processor pays determined?
Definition
It can be determined by one of the following:
1. supply and demand
2. A price set by bargaining between the procesor and a producer association
3. A price determined by previously agreed upon formula, as in federal order markets 
Term
What Act, allowed for a recent change in the dairy market?
Definition
The Federal Agricultural Improvement and Reform Act.  The purpose of this act was to 1. consolidate the 33 federal orders into 11 orders and 2. create a more equitable ssytem for producers and processors
Term
What is the Multiple Component Pricing System?
Definition
It is the most recent milk pricing system.  This system places a value on milk based on its most valuable components, protein, fat, and other solids, in accordance with their use in consumer purchased products.  Under the MCP system, dairy farmers are provided a greater incentive to produce the components in milk of highest value, flavor, and nutrition.
Term
What percent of fluid milk leaving production units is processed for consumption as whole milk, skim milk or low fat milk?
Definition
38-40 %
Term
What is dried skim milk useful?
Definition
Dried skim milk, with only the water and fat removed, is very high in protein and highly digestible.  The protein is also of high quality, containing significant levels of critical amino acids, so dried skim milk is valuable in feeds for non ruminants such as pigs, chickens, claves, and also pets.
