Abstract

The invention provides a dairy cow breeding technology and relates to the technical field of agricultural breeding. The invention includes breeding planning; sexual maturity and first mating age of dairy cows; estrus period of cows; first estrus of cows after giving birth; estrus identification of cows; winter management of dairy cows. Through the understanding of the reproductive physiology of dairy cows, the present invention carries out scientific feeding and management at each growth stage of cows, so as to ensure that the success rate of mating and insemination is improved during the estrus and mating periods of dairy cows, so that calves have a high survival rate and a high growth rate. The advantages of rapid and less disease, rich and balanced nutrition in dairy cow feed, improve the milk production rate of dairy cows, and ensure the normal growth and development of dairy cows.

Description

technical field [0001] The invention relates to the field of agricultural breeding technology, in particular to a breeding technology for dairy cows. Background technique [0002] The cow's head is well defined and slightly elongated. The neck is thin and wrinkled. Thin skin, short capillaries, less subcutaneous fat, well-proportioned body structure, delicate and compact, with clear edges and corners. The hindquarters are more developed than the forequarters, the breasts are huge, weighing up to 11-28 kg, and the mammary veins are obvious. It has poor heat resistance and has high requirements for feeding and management. There are nearly a hundred breeds of dairy cows in the world, among which the most famous ones are Holstein, Jersey, Guernsey, and Ayrshire. At the end of the 18th century and the beginning of the 19th century, China began to introduce Western specialized dairy breeds. The breed of Chinese black-and-white dairy cattle has been bred by crossbreeding black...
