Feed for dairy cows at lactation later period

Abstract

The invention relates to feed for dairy cows at lactation later period. The feed is prepared from the following raw materials: trifolium repens, mulberry leaves, herb of Japanese youngia, bur beggarticks herb, propylene glycol, water caltrop, vitamin B, DL-methionine, platycodon grandiflorum, root of alligator alternanthera, papayas, uniflower swisscentaury root, root of gmelin globethistle, thalictrum aquilegifolium and pine needle leaves. The feed for the dairy cows is balanced in nutrient match, contains enough effective fibers, is easy to digest, has high nutrient concentration and has the property of resisting infection in breasts in a broad-spectrum and efficient manner; mastitis of the dairy cows can be reduced; and compared with pollution and dangers, caused by high cost of antibiotics and chemical additives, the papayas, uniflower swisscentaury root, root of gmelin globethistle, thalictrum aquilegifolium and pine needle leaves in the feed have the advantages of wide source, low cost and no residues, and are added to the feed for the dairy cows at the lactation later period, so that the speed of lactation amount can be lowered and the average daily lactation amount of the dairy cows at the lactation later period also can be increased.

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed, in particular to a late lactation feed for dairy cows. Background technique [0002] Chinese black-and-white cows are the breed of dairy cows with the highest milk production, the largest number and the widest distribution in China. Under normal feeding conditions, the milk production of most cows can reach a certain level. The growth and development of dairy cows is related to the feed ration There is a close relationship. According to the statistics of dairy cows raised by farmers, the cost of feed accounts for more than 60% of the production cost of fresh milk. Therefore, attention must be paid to the diet coordination of dairy cows. After the peak lactation period, dairy cows enter the middle and late lactation period. The characteristic of this period is that the milk production gradually declines. Many researchers and producers have paid attention to improving the milk product...

[0002] Chinese black-and-white dairy cows are the breed of dairy cows with the highest milk production, the largest number and the widest distribution in China. Under normal feeding conditions, the milk production of most cows can reach a certain level. The growth and development of dairy cows is related to the feed ration There is a close relationship. According to the statistics of dairy cows raised by farmers, the cost of feed accounts for more than 60% of the production cost of fresh milk. Therefore, it is necessary to pay attention to the diet coordination of dairy cows. After the peak lactation period, dairy cows enter the middle and late lactation period. This period is characterized by a gradual decline in milk production. Many researchers and producers have paid attention to improving the milk production of dairy cows, especially in the late lactation period. Various milk enhancers, additives, prolactin, etc. have also emerged as the times require. Some products have inconsistent, insignificant, and There are shortcomings such as drug residues, it is difficult to promote and be accepted by dairy farmers
