Problems solved by technology

Existing pig breeding mostly adopts large-scale self-propagation and self-supporting methods. Due to the influence of the breeding environment and breeding methods, the existing pigs have poor immunity, which affects the pregnancy rate and embryo survival rate of sows, resulting in a low reproductive rate of pigs. Low

Embodiment 1

[0017] A kind of breeding method that the present invention proposes to promote the pig breeding comprises the following steps:

[0018] S1. When the weight of Erhualian pigs is less than 70Kg, the maximum feed intake can be provided for them to eat freely. When the weight reaches 80Kg or the age of 5 months, the feed intake can be controlled and can be reduced to 90% of the maximum feed intake;

[0019] S2. Select a 7-month-old male pig as the male parent of Erhualian pig and a 6-month-old young sow as the female parent of Erhualian pig, and intramuscularly inject 20 micrograms of ovulation-stimulating hormone into the female parent of Erhualian pig. The male parent of the Hualian pig and the female parent of the Erhualian pig were mixed at a quantity ratio of 1:25;

[0020] S3 30 days before pregnancy, add 12% feed additives in the feed, feed additives include vitamins, folic acid, organic trace elements and amino acids, wherein the weight percentage of each component is 25%...

[0023] A kind of breeding method that the present invention proposes to promote the pig breeding comprises the following steps:

[0024] S1. When the weight of Meishan pigs is less than 60Kg, the maximum feed intake can be provided for them to eat freely. When the weight reaches 80Kg or the age of 5 months, the feed intake can be controlled and reduced to 85% of the maximum feed intake;

[0025] S2, select the boar with a body weight of 100Kg as the male parent of Meishan pig and the young sows 2 months after puberty as the female parent of Meishan pig, and intramuscularly inject ovulation-stimulating hormone 18 micrograms into the female parent of Meishan pig, The breeding male parent of Meishan pig and the female parent of Meishan pig are polycultured at a quantitative ratio of 1:15;

[0026] S3 28 days before pregnancy, add 8% feed additives in the feed, feed additives include vitamins, folic acid, organic trace elements and amino acids, wherein the weight percentage of eac...

Embodiment 3

[0029] A kind of breeding method that the present invention proposes to promote the pig breeding comprises the following steps:

[0030] S1. When the weight of Hetao big-eared pigs is less than 80Kg, the maximum feed intake can be provided and allowed to eat freely. When the weight reaches 80Kg or the age of 5 months, the feed intake can be controlled and reduced to 88% of the maximum feed intake. ;

[0031] S2. Select an 8-month-old boar as the male parent of the Hetao big-eared pig and a 6.5-month-old young sow as the female parent of the Hetao big-eared pig, and intramuscularly inject 25 micrograms of ovulation-stimulating hormone into the female parent of the Hetao big-eared pig , the male parent of Hetao big-eared pig and the female parent of Hetao big-eared pig are polycultured at a ratio of 1:30;

[0032] S3 35 days before pregnancy, add 15% feed additives in the feed, feed additives include vitamins, folic acid, organic trace elements and amino acids, wherein the weig...

Abstract

The invention discloses a breeding method for promoting pig breeding. The method comprises the steps of when the weight of a pig is below 60-80 kg, using highest food intake amount for the feeding, when the weight reaches 80 kg or the pig grows to 5 month old, controlling the food intake, selecting a pig breeding male parent and a pig breeding female parent for mixed breeding, before pregnancy increasing feed additives, observing the estrus condition of the pigs, urging the pig to copulate, after the copulation, dividing the pig breeding male parent from the pig breeding female parent, after piglets are born, in the breast-feeding period of the pig breeding female parent, guaranteeing the food intake amount, continuing to increase feed additives, nurturing the ovary, uterus and breast of the pig breeding female parent. The breeding method for promoting pig breeding can effectively enhance the pig reproductive efficiency and capability. By increasing the feed additives, the pig immunity can be effectively strengthened, the pregnancy rate and embryo survival rate are enhanced, and the fertility rate and piglet quality are increased. The breeding method has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a breeding method for promoting pig reproduction. Background technique [0002] Live pigs are living pigs, a general term for domestic pigs other than breeding pigs that have not been slaughtered, and are domestic fat animals for food. Pigs are omnivorous animals, generally referring to livestock and mammals, with fat bodies, short limbs, and long noses and muzzles. The meat is edible, the skin can be tanned, the body is fat and the limbs are short, the nature is gentle, the adaptability is strong, easy to raise, and the reproduction is fast. There are black, white, sauce red or black and white flowers and other colors. Pigs can be bred 5-12 months after birth, and the gestation period is about 4 months. The average lifespan of a pig is 20 years. With the continuous improvement of people's living standards, people's demand for meat is increasing, which promotes the ...
