Lodge Lick Brick (Mineral Lick Brick) Solve the problem of breeding of female animals, solve pica, extend the peak period of lactation, improve the feed conversion rate, etc.
It is not good for calves to be weaned too early or too late, which is not good for the growth and development of cattle. It is understood that beef calves are best weaned at 3-4 months. For weaning calves, should also be to strengthen the feeding and management.
Generally, 3-4 months old is the most completely weaned, which needs to be determined according to the calf's physique and environment. For example, calves with poor physique or low winter temperature can be weaned later, while calves with strong physique and suitable temperature can be weaned earlier.
Note:
Weaning causes fundamental changes in the diet of calves, which may sometimes cause stress reactions in calves. In order to reduce the adverse effects of weaning on calves, the principle of gradual progress should be adopted. That is, 15 days before weaning, the amount of concentrate and roughage should be gradually increased, and the amount of milk should be gradually reduced. The daily feeding frequency is changed from 3 times to 2 times, 2 times to 1 time, and then 1 time every other day. When weaning, they were also fed 1:1 watered milk, and gradually increased the amount of water, and the last few days were completely replaced by warm boiled water.
During weaning, keep the ambient temperature suitable (10~30 ℃), keep the livestock house clean and clean, drink enough water, and provide the calves with nutritious, easy to digest concentrate and high-quality green hay, as well as increase the licking of mineral lick bricks. During weaning, the breeders should keep relatively stable, and observe the behavior of calves. If abnormal phenomena are found, they should report them in time and ask the technicians to solve them.
1. Feeding method
After weaning, to continue to feed the calves before weaning coarse feeding and intensive feeding, and with the growth of the age, to gradually increase the amount of intensive feeding. When the month is 3-4 months old, the intensive feeding should be increased to 1.5-2kg per day. At the same time, high-quality hay should be selected for free feeding. Before the age of 4 months, the green feed should be fed as little or no green feed as possible. After the age of 4 months, the intensive feed for breeding cattle can be fed instead. When the calves appear weaning stress reaction, no need to worry, as it gradually adapt to plant feed, feed intake increases, will soon recover, while increasing mineral licking brick licking.
2. Reasonable grouping of groups
Before weaning, calves need to be reared in a single circle, while previously mixed breeding needs to be reared in groups. Reasonable grouping is of great benefits to feeding management. The principle of grouping and grouping is generally arranged together according to the month age and weight of calves, and it is generally appropriate to control 10-15 calves in each group.
3. Strengthen management
After grouping, free-range feeding is adopted. Generally, only sufficient drinking water and feed are required. The feed must be fresh and hygienic. The eyes are fed with moldy and rotten feed so that calves can eat and drink freely. While ensuring the quality of feed, it is also necessary to ensure the sanitation of the enclosure, clean it in time every day, and consume it regularly to reduce the possibility of diseases.
In addition, whether adult or just weaned calves, in addition to ensuring adequate feed, but also need to have a certain amount of exercise, generally not less than 2 hours a day, try to avoid high temperature at noon and rainy days, which is conducive to the bone development of calves and the absorption of calcium.
