Embodiment 1

[0027] Example 1 Effect of Propionibacterium acidogen on milk yield and milk quality of lactating dairy cows

[0028] The first calving Holstein cows were selected, and the feeding cycle was from 2 weeks before delivery to 30 weeks after delivery. The experiment was divided into six groups, with 10 cows in each group. By weight, the composition of the corn silage mixed ration described below is: 25.37% corn silage, 37.23% wheat, 7.53% whole cottonseed soybean meal, 7.88% corn bran feed, 20.85% alfalfa, 0.18% table salt, 0.39% calcium carbonate %, sodium bicarbonate 0.39%, magnesium oxide 018%.

[0029] The blank group was: corn silage mixed ration (4kg / head / day), fed once a day in the morning and evening;

[0030] The yeast culture group was: yeast culture (50g / head / day) and corn silage mixed ration (4kg / head / day), fed once a day in the morning and evening, each feeding, the yeast culture was given first, and then Give corn silage mixed ration;

[0031] Propionibacterium a...

Abstract

The invention discloses a breeding method capable of improving milk yield of dairy cows and quality of produced milk and application of acid production propionibacterium in preparing supplement feeds for improving milk yield of dairy cows and quality of produced milk. The breeding method is that before lactation period cows are fed general feeds, each cow is fed 5-100g of acid production propionibacterium every day. Preferably, each cow is fed 20-40g of acid production propionibacterium every day. By means of the breeding method, milk yield of lactation period cows is improved, and lactose and milk fat content in the produced mil is further improved. In addition, the breeding method has good industrial value.

Description

technical field [0001] The invention relates to a feeding method for improving milk production and milk quality of dairy cows and the application of propionibacterium acidogen in preparing supplementary feed for improving milk production and milk quality of dairy cows. Background technique [0002] In recent years, with the continuous and stable development of China's economy and the improvement of per capita living standards, the country and localities have listed the dairy industry as a prominent industry. In recent years, the size of the domestic dairy market has increased substantially. From 2000 to 2005, milk production increased by 211.7%. However, compared with developed countries, the overall development level of my country's dairy industry is not high. According to the analysis of authoritative organizations, the per capita consumption of urban residents in my country is only about 20 kilograms per year, which is 1 / 5 of the world average level, while the per capita ...
