Novel peptidase for preventing sow propagation and preparation method of peptidase

Abstract

The invention discloses novel peptidase for preventing sow propagation, and a preparation technology, using method and application of the peptidase. The novel peptidase for preventing sow propagationconsists of the following components in percentage by weight of 50-65% of peptidase, 10-20% of subtilin, 10-20% of soybean isoflavone, 2-8% of catalase and the balance a carrier. 0.1% of the novel peptidase is added for feeding, after one period, the propagation and metabolism obstacle of the sows can be relieved, involuntary muscle of wombs is regulated, the anxiety degree of the sows at the prenatal period is reduced, and the childbirth time is shortened to 3 hours or less. The peptidas is used for activating the metabolism of protein and fat, the synthesis and metabolism capacity of liver can be accelerated, and improvement of milking capacity can be promoted. The ovarian function is regulated, the melting time of corpus luteum of the sows after weaning is controlled to 2-3 days or shorter, and many double blind experiment conforms that the effective rate is 93.3-96.9%.

Description

technical field [0001] The invention relates to the field of breeding industry, in particular to a novel peptidase for preventing sow reproduction and a preparation method thereof. Background technique [0002] In the animal husbandry industry, pig farming is the largest type of farming. In pig farming, sow breeding is one of the most important tasks. At present, some problems in sow breeding are still unresolved. The main problems include: [0003] 1. The permanent corpus luteum, which causes the sows to be in estrus periodically, and the sows have to be eliminated in advance. As a result, the elimination rate of sows is as high as 11.9%. There is no targeted solution for this in the industry. [0004] 2. Reproductive and metabolic disorders in sows lead to insufficient secretion of estrogen. During the reproductive process, uterine smooth muscle contraction is weak. The normal labor process is 4-5 hours. When the uterine contraction is weak, it can reach more than 10 hour...

AI Technical Summary

Problems solved by technology

[0003] 1. Permanent corpus luteum, which causes sows to be in estrus periodically, and sows have to be eliminated in advance, resulting in a 11.9% elimination rate of sows. There is no targeted solution for this in the industry

[0004] 2. Reproductive and metabolic disorders in sows lead to insufficient secretion of estrogen. During the reproductive process, uterine smooth muscle contraction is weak. The normal labor process is 4-5 hours. When the uterine contraction is weak, it can reach more than 10 hours. The long labor process directly leads to delayed labor. In severe cases Cause dystocia and weed out, delayed labor increases stillbirth rate and weak offspring rate or dystocia weed out, there is no effective solution at present

[0005] 3. Abnormal energy conversion of sows after reproduction, decreased milk production during lactation, and slow growth of piglets

The addition of a large amount of aphrodisiac powder, the smell of traditional Chinese medicine and poor palatability, caused 36% of sows anorexia, the fiber of traditional Chinese medicine is rough and poorly absorbed, the effective rate of promoting estrus is only 4-6%, the effective rate is very low, and it cannot effectively solve the problem of estrus and breeding

[0007] For problems such as permanent corpus luteum, slow ablation of corpus luteum, and prolonged labor, there is currently no definite and effective solution
