I reproduction of all animals. These minerals are calcium, chlorine, cobalt, copper, iodine, iron, magnesium, manganese, phosphoric, potassium, sodium, sulfur and zinc. Even the best forage do not contain enough sodium and chlorine Salt is fed to correct this deficiency, Some forages are deficient in calcium and phosphorus. Mineral mixture should be fed in this case to provide the cattle with the necessaj \ amount of calcium and phosphorus. Dairy cows must have forages high in carotene to produce milk rich in vitamin A. Green grasses and legumes from fertile pasture provide all the carotene that dairy cows need. For the most economical milk production about 30 percent ol tin nutrients required by dairy cows should come from green forage, ha\ 'and silage. High-producing herds need grain and protein concentrates in addition to forages. In planning rations for dairy cattle one must select feeds that pro v i< |e sufficient amounts of the necessary nutrients, one should provide enough carbohydrates, proteins, minerals, vitamins and water. IV. Прочтите текст. Озаглавьте абзацы по-английски. For the winter ration, legume hay should be the main roughagi feed. Good-quality hay is leafy and green in colour. Silage is a good roughage for winter feeding. Corn silage is low in protein but it provides carbohydrates for energy. Grass crops and legumes are also used to make silage. Legume silage is higher in protein than either grass oi corn silage. If low-protein hay such as timothy hay is fed, a grain mixture must be fed to provide increased protein. High-producing cows require more protein than low-producing ones. Feed the grain mixture to ea< h cow in the herd in proportion to the milk produced by her. 59 can be provided by feeding silage and hay. V. Прочтите текст.

Management of Cattle on Pasture Grazing normally begins in spring when pastures have dried up to some extent and when the growth of the grass is sufficient*to begin grazing. It is generally best to give the cattle a good feed of hay or oat straw in the morning before turning them out to pasture for the first time. Sometimes cattle are turned out for 3 or 4 hours during the day time for the first week. Large fields are better divided into smaller areas and grazed either by smaller groups of cattle in each or by the rotational grazing system, when the whole herd is put into one enclosure for a week or 10 days and then moved to the next one. By such grazing each area is heavily grazed and manure is concentrated upon it. In late summer and autumn the grass becomes scarce and the cattle should be provided with hay or various green succulents such as maize, cabbage, roots and others. It is important to begin giving supplementary feeding in time, for cattle may loose their weight before supplementary feeding starts. For cattle of each class there are certain common principles of barn management. Cattle, especially young stock, should be provided with a dry, light and well-bedded barn. Good bedding provides a comfortable bed for the cattle, keeps them clean and absorbs the liquid manure. A clean and adequate water supply is of the greatest importance. The more concentrated ration is the more water is required. Regularity in the time of feeding is very important. Systems of feeding vary, but generally about half the root ration and hay are given in the morning and the other half in the evening. Cake is given in the daytime and at the same time the mangers are filled with hay, oat or barley straw. Where no roots are fed, some green succulent food should be provided. 60 VI. Прочтите текст.

The length of the feeding period may vary from 2 to 12 months, depending on the age and condition of the cattle. The cattle that are more than two years old may be fattened quickly if they are in good condition. Calves that are leas than two years old may be fattened in four to nine months. Sometimes it is profitable to feed calves nine months or longer. Cattle should not be given too much grain at the beginning of the fattening period. Some farmers use less grain and more high-quality forage during a longer feeding period. Sometimes it is profitable to give the cattle some legume hay or protein concentrate late in the summer when grass is maturing. Corn silage, grass silage or carrots' may be used in the ration of breeding cows when they are not on pasture or when pasture forage is scarce. A mineral supplement should be provided if cattle are fed with crops produced on the soil that is known to be deficient in calcium, phosphorus or other essential minerals. Animals should have plenty of water and salt when they are being fattened. Выразите свое согласие или несогласие со следующими утверждениями основываясь на информации, полученной из текста.
