Breeding method for improving milk yield of dairy cows

Abstract

The invention discloses a breeding method for improving the milk yield of dairy cows. The method comprises the steps of playing musics every hour before and after each eating; in the spring, autumn and winter seasons, filling light through lamp illumination, and in winter, feeding the dairy cows with water of 38-40 DEG C; impregnating nipples of the cows; proceeding to seed selection, diary cow pregnancy preparation period, diary cow perinatal period, diary cow lactation early period, diary cow lactation peak period and diary cow lactation late period. The method can improve the milk yield ofthe diary cows by playing the musics to the diary cows, massaging the nipples, exercising and filling the lights for the diary cows in the spring, autumn and winter seasons; different feeds are fed during different growth stages of the cows, the nutritional needs of the cows are ensured, the body immunity is enhanced, the lactation performance is improved, the production time is effectively prolonged, and the milk yield is improved; the nipples of the diary cows are impregnated regularly with 0.3% chlorhexidine solution to prevent the occurrence of garget; cow bodies are rubbed regularly for disinfecting, the body immunity of the diary cows is improved, the circulation of cow blood is promoted, and the appetite and the milk yield of the cows are improved.

Description

technical field [0001] The invention belongs to the technical field of dairy cow breeding, in particular to a breeding method for increasing milk production of dairy cows. Background technique [0002] Milk is the most nutritious food, and there are mainly 5 kinds of nutrients contained in it. One is protein, which is an important part of the human brain, nerves, muscles, blood, etc. The protein content in fresh milk is 3-3.5%, mainly casein and whey protein, and its biological value is 85, while the biological value of cereal protein is only 50-65. Milk protein is a complete protein with a digestion and absorption rate of over 98%. In addition, the ratio of protein to calories in milk is also perfect, which not only has enough protein, but also ensures calories. The second is fat. The fat content in fresh milk is 3-4%, which provides about 48% of the calories of whole milk. The fat of milk is in the state of chytrid very small particles, with a low melting point and easy...

Problems solved by technology

Nowadays, it is difficult for people to deal with the milk in the middle stage of lactation, and there are often problems such as substandard quality and rapid yield decline, and with the increase of intensive breeding time, the long-term single bias of feed components is unreasonable for the body adjustment of dairy cows , the milk quality and milk volume are not as good as the year after year, even in the peak lactation period, there will be quality fluctuations, milk volume decline and other problems
