The newly born calf is 1-1.2 meters tall and weighs about 60 kilograms. The lactation period of Luxi cattle is usually 6 months, and the calf period is the calf that points to the period before 6 months of age. Here we look at the characteristics and management measures of the calf period.
1 Timely feeding of calves
The nutrient supply started after the calf's calf was born was completely dependent on breast milk, and it began to ruminate after 3-4 days until it could use a small amount of concentrate. Breast milk was the main source of nutrition. In general, breast milk can basically satisfy the growth and development needs of yak within one month after the calf is born. However, after 30 days, breast milk alone cannot meet its growth and development needs and must be supplemented.
The yak can be mixed with soybean meal, bran, and a small amount of salt at the age of 30 days. Each calf is fed 150--200 grams a day and fed twice.
As calf intake increases, adequate drinking water must be guaranteed. When the yak grows to 60 days old, the rumen volume gradually increases, the function starts to improve, and the roughage can be digested and utilized. At this time, the concentrate and the silage can be mixed and fed, and the ratio of the silage to the concentrate is 3: 1, the total amount of 1-1.5 kg mix, fed twice a day. Concentrate can also be used with more raw materials to match, the general formula of fine material: corn 50%, soybean cake 30%, wheat bran 12%, fish meal 5%, calcium carbonate 1%, salt 1%, bone meal 1%.
The yak grows up to 90 days, that is, when it is 3 months old, it can feed the mixed feed of silage and concentrate every day. The total amount is 1.5-2 kg; after 4 months of age, it is fed 3- 4 kg every day; May After the age of feeding 5--6 kg. If you are not eager to supplement feed, with the increase of age, the nutrients needed for the growth and development of calves will be lacking, which will cause the growth and development of calves to be obstructed. This is also the main reason for the low weight of calves at 6 months of age. The 6-month-old yaks that have not been over-fed are generally between 100--120 kg in body weight, while the yak after supplementation can weigh 160--180 kg.
2 Daily brushing of cattle body during calf
Luxi cattle calves basically adopt the cowhouse breeding method, so the cow's skin will be contaminated by fecal matter and dust to form dirt, which not only reduces the thermal insulation and heat dissipation of the fur, but also worsens the blood circulation of the skin. It is easy to get sick, so brush your calf every day.
3 Yak period daily cleaning
The cleanliness of yaks is related to the health of burdock, so the cleanliness and hygiene of the sheds and the playground must be maintained. When cleaning, put the calf aside, so as not to scare the calf when cleaning and disinfecting, and to affect its appetite. The cleaning should be thorough, the excrement should be cleaned in time, the ground should be filled with water in summer, and winter should not be frozen.
4 Weekly disinfection of yak period sheds
Important measures for purifying the environment during disinfection, in order to improve the hygienic conditions of the sheds and surrounding environment, to develop a habit of regular disinfection. The yak's shed must be sterilized and the calf must be properly disposed of. Then the sterilizer must be sterilized in a circle. The sterilizing should be thorough. The sterilizing includes disinfection of surrounding walls, floors, fences and other facilities, so as to keep the yak barn clean and eliminate. Pathogens.

5 Calf vaccine injection
Diarrhea is the most easily acquired disease for calves. After calves are born, they are easily infected with Escherichia coli or Salmonella due to unhealthy nursing, eating dirt, drinking dirty water, and being cold. Symptoms of enteritis and diarrhea. It is very necessary to take a shot of the vaccine only once a month, and the vaccine must be purchased from a regular veterinarian and injected according to the instructions.
6 Injection of foot-and-mouth disease vaccine in calves
