In the breeding process of yak, feeding grass early or late is not good for the growth and health of yak. Then, when is it most appropriate to start feeding grasses for yaks? Chinese herbivore nutrition experts explained that it is most appropriate for yaks to start feeding grass at the age of 3 weeks.
Because the burdock soon after birth (within 3 weeks of age), its forefoot (rumin, reticulum, valve) is very young and young, does not have the function of digesting forage, there is no microorganism and ciliate, only by eating milk Into the stomach (abomasum) for absorption and utilization. Feeding forage at this time will increase the burden on the yak's pre-gastric (rumin, reticulum, and valve-stomach) and cause illness. If the grass feed is too late, the stomach and intestines depend on the juice of the juice for a long time. The stomach and intestines do not exercise. The front stomach grows slowly. Its content is too small, and young people and young adults eat less, affecting growth and development. health.
After 3 weeks of age, the yak has rapidly increased its foregut, and the microorganisms enter the fore stomach as a result of exposure to small amounts of food and drinking water. At this time, the yaks also begin to cud. At this time, fresh green grass, wild vegetables, vegetables, leaves, high-quality dried grass, crushed fine feed, etc. are started to be fed, and the amount of feed and the amount of roughage are increased as the age of the week increases. In this way, the diseases caused by the overly tender stomach and the prostomach can be prevented, and the development of the forefoot stomach can be accelerated. This can promote the reproduction of rumen microorganisms and ciliates, and gradually increase the function of the digestive feed. After that, it can feed a large amount of roughage and guarantee normal The growth and development laid a good foundation.
Fruit and Vegetable Powder is the fresh fruits and vegetables through the international advanced level of freeze-drying technology and equipment, after pretreatment, quick-freezing, vacuum drying, ultraviolet sterilization, packaging storage and other more than 10 processes.
Fruit and vegetable powder Advantages
1, low moisture content, can extend the storage period, reduce storage, transportation, packaging and other costs;
2, the utilization rate of raw materials is high, it does not have high requirements for raw materials, especially the size and shape of raw materials have no requirements;
3, broaden the application range of fruit and vegetable raw materials, little nutritional loss. Research shows that fruit and vegetable powder can be used in almost every field of food processing, can be used to improve the nutritional composition of products, improve the color and flavor of products, etc.
