38 CALP Cattle are kept for two main purposes: beef production and milk production. The management of a dairy herd differs markedly from that of beef producing animals, for milk production is a daily process. The life of a dairy cow may be divided into three periods. The first period is the one which lasts from the birth of a dairy calf up to about the age of 6 months. The second period lasts from 6 months until the heifer calve a for the first time, usually at about 2,5 years of age. The last period is the period of the maturity of a dairy cow. The calf being normal after birth, the cattleman should leave it with its mother. Being healthy, the calf will soon get to its feet and start nursing. The first milk, colostrum, is very important for the new-born calf. It ic secreted by the cow for 4 or 5 days after calving. The calf usually sucks its dam for about a week. Then it should be put into an individual pen and taught to drink milk from a pail. Calves should be fed whole milk at the same temperature as milk from the udder of the cow, the rate being about 1 to 1.5 gallons a day. Feeding cold milk or too much milk will cause scours. Feeding at irregular intervale may cause digestive troubles too. Calves being 3 weeks old, other feeds containing fibre should be given. All calves at this age should have access to a small amount of good-quality hay and clean water. • Whole milk is to be given until calves reach 8 to 10 weeks of age. Calves reaching this age, whole milk must be gradually decreased and skim milk or a milk substitute is given. From this age on dry feeding is increased while milk is decreased. Calves should be turned out to pasture in spring as early as possible. Being kept on good pasture in summer, calves do not require any other additional feed. Calves being on poor grass, large amounts of hay, roots and a small amount of concentrates are necessary in addition to pasture. In winter calves should receive legume or grass hay. The quantity of grain is different, depending on the quality of hay fed to the calves. Young heifers reaching about 18 to 20 months of age, a careful watch is kept upon them and when they come into heat, they are bred. Пояснения к тексту

3. How many most commonly bred beef breeds are there in the USA? 4. What is a dual - purpose breed? Cattle Breeds There are many breeds of both dairy and beef cattle. Some of them are high-productive. The productivity of others may be average or low. The cattle of dairy breeds are raised by man for the production of milk which is very important for the diet of the people. In the Northern areas of the USA the Holstein is the leading dairy breed. In the Southern states the Jersey is more popular than other dairy breeds raised there. 42 Beef breeds are kept not for milk but for meat. There are five most commonly bred beef breeds in the USA. Most farmers breed the Shorthorn and Hereford beef breeds of cattle. There are also breeds which are kept for the production of both milk and meat. Such breeds are known as dual-purpose breeds. Two of them, the Red Polled and Milking Shorthorn are known as the best dual-purpose breeds of cattle in this country. LESSON 9 ТЕМА: MATURE DAIRY COW ГРАММАТИКА И ЛЕКСИКА

Calves are believed 43 to be on pasture now. 4. Feeds are known to vary in water content. 5. Proteins are known to be complex substances. 6. This beef breed has been found to be the bast in our region. 7. Concentrates are known to be high in protein. MATURE DAIRY COW The period of maturity of a dairy cow lasts from about 2.5 years onward. The gestation period in cows is known to last about nine months. The cow in calf should be dried off at least six weeks before calving. Dry period may vary ic different cows. During this period the cow should be given plenty of roughages and some grain unless she is in good flesh or on good pasture. The more milk is drawn off from the cow's udder the more will be secreted. That is why to dry off a cow the number of milkings should be reduced to one daily at first and then she should be milked every other day. About a week before the calving date wheat bran should be given to the pregnant cow. Bran is known to be a cooling and laxative feed. It is very desirable for the cow before calving. -A warm, dry, well-bedded stall should be provided for the cow at the time of calving. Calving being normal, no assistance is required. To know when each cow is to calve one must keep a breeding record, showing when cows were bred. Accurate dates of calving may be obtained only when hand mating is practised. The duration of lactation has been found to vary with the age of the cow, the breed and feeding. In the case of a first calver it usually lasts about 8 to 10 months. Some high-yielding cows may produce milk for a year. The better the cow is fed and cared for, the longer is the period of lactation. In preparing rations for milking cows many factors should be considered. Rations are to provide carbohydrates in a readily available form, have the proper amount of good quality protein, provide sufficient fat and mineral matter and contain the necessary vitamins. To obtain high milk yields is the aim of every cattleman. That is why they try to supply their cows with nutritious feeds. The more nutritious is the ration the more milk the dairy cows will produce. Unless dairy cows are fed the proper amount and kinds of feeds, they will not be provided with sufficient nutrients to produce high milk yields. 44 A dairy cow is known to require a very liberal supply of water, 3 to 4 gallons of water being needed for each gallon of milk produced by the cow. No increase in milk yields will take place if feeding and management conditions are improper. Пояснения к тексту
