Calf Feeding Management
Calf Feeding Management
Calves generally refer to calves from birth to weaning (usually weaned at 6-8 months of age). This stage of growth and development is the most rapid period of life of a cow. Therefore, we must do a good job of feeding and management of yak.
Feeding Technology After the calf's nursing calf is born, it is first necessary to use a clean cloth to wipe away the mucous from all parts of the body. In addition, after the yak is born, the umbilical cord is not broken and the umbilical cord should be torn off. The method is: After about 10 centimeters from the yak navel, use 5% iodine to disinfect and hand-pull the blood in the umbilical cord downwards, and then use the sterilized string to tie the two knots at the upper and lower ends of the calf, then The umbilical cord was torn from the middle of the two knots and finally iodine was applied to the cross-section.
The milk produced in the first 7 days after a cow gives birth to a calf is called colostrum. Colostrum is rich in protein, minerals, vitamins and other substances, is an indispensable food for newborn yak, and has special functions for its growth and development. Therefore, in order to obtain more nutrition for calves, it is necessary not only to allow calves to eat colostrum, but also to eat colostrum as soon as possible. Generally, one and a half to two hours after the yak is born, it can be fed. If cows do not have colostrum or milk is low, artificial milk can be used instead. The formula is: 250 grams of milk, 10 grams of salt, 3 eggs and 15 to 20 grams of fresh cod liver oil mixed thoroughly, heated to 38 °C -40 °C feeding.
The nursing cows in the lactation period can be fed into the regular milk after the period of colostrum. The lactation period of cows is generally 3-4 months, and the total feeding amount is about 300-350 kg. Feeding 3-4 times a day, the amount of feed for one day can be calculated as 8% of calf's body weight. During this period, it should be done: on the one hand, it is necessary to increase the amount of concentrate feed for cows to increase milk production; on the other hand, it is necessary to train calves to eat plant feeds (including grass, hay, and concentrates) earlier to strengthen the stomach. Digestive function.
Supplying sufficient water The milk produced by cows contains more water, but the calf's daily milk consumption is limited. The water extracted from milk cannot meet the needs of normal metabolism. Therefore, in addition to feeding and proper feed during feeding, the yak should also drink some fresh water.
Management technology manages yak mainly to do a good job in the cleanliness of the cowshed and cattle body. Clean and disinfect the barn regularly to keep it clean and dry. The second is to allow calves to exercise properly. Yak cattle can be allowed to move freely on the sports field 8-10 days after they are born, but care should be taken not to allow them to move under the hot sun to prevent heat shocks in calves. The third is to do a good job of preventing diseases. Yaks are more susceptible to the first few weeks after birth, especially diarrhea and pneumonia. Therefore, during the breeding of yak, it is necessary to strengthen the care of yaks and do a good job in sanitation to reduce the incidence rate.

Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
