On August 10th, Zhang Wenyuan, a reader of Tianwang Town, Baocang City, Shaanxi Province, called the newspaper to ask about cow dairy farming. To this end, the reporter interviewed Associate Professor Xin Yaping, a master tutor of the Academy of Sciences of Northwest Forestry University, and he said that the ideal Female cows are cows with high milk production, young age, good health, no disease, and good appearance. A good dairy cow looks like a triangle from a distance. The black-and-white flowers are clearly distributed and well-proportioned. In close quarters, the coat is shiny, the bones are thin and strong, the skin is thin and tight, and it is not thin and fat and lively; the head is small and The length and width of the chest are deep and moderate. The abdomen is large and round, and the back and back are straight. The minister is straight and straight. The breasts stretch forward and backward, and the breasts are developed. The four nipples are well-proportioned. The elasticity of the breasts is good with the hands, the milk wells before the milking are obvious, the breasts are enlarged, the breasts are smaller after milking, and the back of the breasts are obviously wrinkled. This is characteristic of high-yielding cows.
Finally, before the transaction, you must check with the veterinary health and epidemic prevention department whether the cattle you are looking for have infectious diseases such as tuberculosis and brucellosis, whether the genital organs are normal, whether they are heterosexual twins, and heterosexual twins do not. Reproductive power, do not buy it.
In the feeding process should also pay attention to the following questions:
Do not remove the grass to feed freshly removed ammonified grass ammonia smell, before the feed should be thinly spread in a cool and ventilated place for 10 to 24 hours, until no stimulation of the nose after the ammonia taste fed. Pay attention not to expose the grass and dry it too much, so as not to affect the ammoniating effect.
Avoid the single ammoniated weed grass after ammoniated treatment, energy and non-protein nitrogen content increased, but also with the feed when the bean cake, cottonseed cake, or legume fodder to ensure the balance of metabolism.
Avoid feeding too much to begin feeding aminated grass, should be from little to more, gradually increase, there are 7 to 10 days of adaptation period, to replace the original fed grass, and to account for the total daily amount of grass 2/3 ~ 4 /5 is appropriate. To increase the amount of corn and other energy feeds for the mixed concentrate, provide raw materials for the rumen microbes to make full use of non-protein nitrogen.
Avoid feeding aminated grass cows in the rumen of microorganisms to adapt to ammoniated grass have a process, frequent changes will affect the growth and weight gain.
Avoid drinking ammonified grass drink plenty of ammoniated grass after drinking, immediately drink water, grass produce ammonia in the rumen, often cause poisoning.
