Artificial fertilization method for pigs

A technology of artificial insemination and sperm, which is applied in medical science, veterinary equipment, animal delivery, etc., can solve the problems of decreased conception rate and number of births, immature technology, and large breeding volume, so as to improve the success rate of fertilization and litter The effect of increasing the number of mature semen and litter size and improving economic benefits

Problems solved by technology

[0002] At present, most pig farms adopt natural breeding, that is, when the sows are in estrus, the sows are driven to mate with the sows to conceive. If the breeding pigs are overused, the sperm survival rate will be low and the dead sperm rate will be high, resulting in low conception rate and The number of litters is reduced; in addition, natural mating can easily lead to the spread of bacteria and viruses, which increases the probability of sows being infected with diseases; moreover, in the natural mating method, a well-bred breeding pig can only mate with one sow at a time, and the sperm utilization rate is low. One breeding pig can mate with 100-150 sows at most in a year. In order to meet the needs of breeding, the breeding volume of breeding pigs is large, the cost is high, and the economic benefit is low
At present, some farms also use artificial insemination for breeding, but due to the immature technology, the pregnancy rate and litter rate are low, and the economic benefits are not significant enough.

Embodiment 1

[0015] Embodiment 1, a method for artificial insemination of pigs, comprising the following steps:

[0016] 1) Preparation before semen collection: Put 500ml of distilled water and 25g of Belgian semen dilution powder sold by Guangzhou Baixu Hesheng Agricultural Co. Put a disposable special plastic bag on the fine cup, and cover with 3 layers of filter paper, and then fix the edge of the filter paper to the cup mouth with a rubber ring, so that the middle of the filter paper is located inside the beaker;

[0017] 2) Unarmed semen collection: the semen collector holds the semen collection cup with his left hand, puts on a sterile rubber glove with his right hand, and squats behind the semen collection platform. , and push the head of the penis with the thumb, and then rhythmically pinch and pull the penis back and forth to make the boar feel pleasure and ejaculate. When ejaculating, spread the thumb and index finger slightly to expose the head of the penis to let the semen ejac...

Abstract

The invention relates to a breeding method for pigs, in particular to an artificial fertilization method for pigs, and belongs to the technical field of breeding. The method comprises the steps of 1 preparation before semen collection, 2 bare-handed semen collection, 3 sperm motility rate and density inspection judgment and 4 artificial insemination. 3-8 pigs can be hybridized through one semen collection of one improved-variety boar, 300-1000 pigs can be hybridized within one year, the number of the hybridized pigs is 3-7 times that of pigs obtained through natural mating, the number of bred boars is greatly decreased, the cultivation cost is lowered, and the method is high in conception rate, high in birth rate and remarkable in economic benefit.
