Problems solved by technology

Although the above-mentioned patent and the method described in the first document can improve the total number of piglets per fetus and the average number of live piglets per fetus, the service cycle is too long and the cost is too high; in addition to the long cycle and high cost, the methods described in the latter two documents It can only increase the number of living pigs per fetus, but has no effect on the total number of pigs per fetus
At present, there is no report on a method to improve the reproductive performance of sows with a shorter period, lower cost and better effect

Abstract

The invention discloses a method for improving the reproductive performance of sows. The method for improving the reproductive performance of sows comprises mixing N-carbamylglutamate with auxiliary materials so as to prepare feed containing 0.01-0.04wt% of N-carbamylglutamate for feeding the sows within 1-28 days after the mating. According to the method, the reproductive performance of sows can be improved significantly; specifically, the average total piglet number of each pregnancy, the average surviving piglet number of each pregnancy and the average healthy piglet number are increased; and compared with the existing method, the same or nearly the same effect is reached, and at the same time the feeding time and the feeding quantity are reduced, and the cost is reduced; and the feeding is performed immediately after the sows mate, and is convenient for the operation in practice.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to a method for improving reproductive performance of sows. Background technique [0002] The content of arginine in pig body tissue protein is second only to leucine, and in the whole process of piglet embryonic development, arginine is always the most abundant nitrogen carrier of body protein, suggesting that arginine is the most important nitrogen carrier for pregnancy in terms of quantity. The importance of sows; in addition to participating in the deposition of body proteins, arginine also plays an important nutritional and physiological role in sows through its metabolites such as nitric oxide and polyamines, and can also act as a stimulator of insulin in pregnant sows. Secretin, suggesting its importance in regulating the reproductive physiology of pregnant sows. The effect of arginine on pregnant sows has been verified in many ways, and it can significantly improve the...
