There are ways to raise calves in dairy farms.Concentrated feeding method and single-circle feeding methodTwo kinds.
1、Concentrated feeding method This is a traditional feeding method, that is, calves from birth to weaning are mixed in the same enclosure and fed on the same trough. After birth, calves are fed through calf beds for 7 days, then mixed with other calves to raise, go up and down the trough together, and then put into the sports ground after going down the trough. The advantages of centralized feeding are convenient feeding, convenient unified feeding and management, saving manpower, and less cattle house area. The disadvantage is that the calf density is large, the pathogenic microorganism transmission opportunity is increased, the incidence rate is high.
2、Single-circle feeding refers to the newly born calves in the calf pen alone, which is an individual feeding method. Calves are kept in a single enclosure (calf grate) from birth to weaning. The advantages of single-circle feeding are low cost, economical and practical; avoid sucking each other, reduce the spread of disease, reduce the incidence of calves; pen fresh air, is conducive to the movement of calves, improve disease resistance; the disadvantage is that the cowshed covers an area of large, grass feeding scattered.
1.Feeding off
After the birth of a calf1－2Hours, to make it eat colostrum, and keep feeding every day4－6 Times. If cows without milk, artificial colostrum can be prepared to feed newborn calves. The formula is: regular milk750ml, table salt10grams, fresh cod liver oil15grams, add eggs2－3After full oscillation, it is heated38 C to feed.
2.Feeding off
Most service and meat calves are fed naturally. Dairy calves are best fed artificially. The method is: feeding with rubber nipples on the bottle. If the calf does not suck milk, the finger can be immersed in the milk, and then stuffed into the calf's mouth for induction, so repeated induction 2-3Second, the calf can suck milk on its own. After each feeding30Minutes to drink.35－38℃ warm water, to be20Days later began to drink raw water. The house should be ventilated, dry and hygienic, and the cattle stables should be changed frequently. After the birth of a calf5－6Day, start brushing the cow body, and pay attention to proper exercise.
3.Weaning off
Calf lactation is generally5－6months, can also be shortened3Months. A newly weaned calf should be fed with nutritious and digestible feed, and pay attention not to change the feed suddenly.1Calves under the age of one year old should be fed with high-quality dry and green grass, and supplemented with feed every day.1－2Kg, salt, bone meal20－30g. After the calf is one year old, it is necessary to change the feed. Its feed standard is: concentrate1－1.5kg, silage or root feed8－12Kilograms, hay6－8kg, and to supplement the right amount of minerals,Increase the free licking of the licking brick, supplementPhosphorus, calcium, zinc, magnesium, iron, cobalt, iodine, manganese, selenium, sodium and other mineral trace elementsEspecially in the growth process of calves, calcium is indispensable to avoid rickets, etc., combined with other trace elements, beneficial absorption and interaction, can improve health index, keep fit, strengthen bones and fat, etc,
