Problems solved by technology

In the modern pig breeding system, prenatal feeding of sows is crucial to the subsequent reproductive performance of sows. At this time, although sows are sexually mature, they have not yet reached physical maturity, and are easily affected by factors such as diseases, management and feeding, resulting in production performance. low

Embodiment 1

[0018] A method for sow breeding, comprising the following steps:

[0019] (1) Before the sow reaches the age of 4 months, the daily feed intake is limited to 80% of the maximum ad libitum intake. When the sow reaches the age of 5 months, the daily feed intake is restricted. The food intake is 74% of the maximum ad libitum intake;

[0020] (2) Breeding at the age of 6 months to 7 months. During the month before the mating, keep the light time 17 hours / day, use artificial light, the light intensity on the first day of the month before the mating is 70lux, and then light every day Intensity increased by 1lux;

[0021] (3) It is divided into two stages since the sow is fertilized, 1-59 days is the first stage, and 60 days to the litter is the second stage, feeding feed A and feed B respectively; the feed A is calculated in parts by weight Made from the following ingredients: 100 parts of wheat, 100 parts of corn, 100 parts of soybean meal, 2 parts of peppermint oil, 8 parts of ...

Embodiment 2

[0026] A method for sow breeding, is characterized in that, comprises the following steps:

[0027] (1) Before the sow reaches the age of 4 months, the restricted daily feed intake is 82% of the maximum ad libitum intake. When the sow reaches the age of 5 months, the restricted daily feed intake The food intake is 76% of the maximum ad libitum intake;

[0028] (2) Breeding at the age of 6 months to 7 months. During the month before the mating, keep the light time 17 hours / day, use artificial light, the light intensity on the first day of the month before the mating is 70lux, and then light every day Intensity increased by 1lux;

[0029] (3) It is divided into two stages since the sow is fertilized, 1-59 days is the first stage, and 60 days to the litter is the second stage, feeding feed A and feed B respectively; the feed A is calculated in parts by weight Made from the following ingredients: 120 parts of wheat, 120 parts of corn, 120 parts of soybean meal, 4 parts of pepper...

Embodiment 3

[0034] A method for sow breeding, comprising the following steps:

[0035] (1) Before the sow reaches 4 months of age, feed freely. When the sow reaches 4 months of age, limit the daily feed intake to 81% of the maximum ad libitum intake. When the sow reaches 5 months of age, limit the daily intake The food intake is 75% of the maximum ad libitum intake;

[0036] (2) Breeding at the age of 6 months to 7 months. During the month before the mating, keep the light time 17 hours / day, use artificial light, the light intensity on the first day of the month before the mating is 70lux, and then light every day Intensity increased by 1lux;

[0037] (3) It is divided into two stages since the sow is fertilized, 1-59 days is the first stage, and 60 days to the litter is the second stage, feeding feed A and feed B respectively; the feed A is calculated in parts by weight Made from the following ingredients: 110 parts of wheat, 110 parts of corn, 110 parts of soybean meal, 3 parts of pep...

Abstract

The invention discloses a method for breeding sows. The sows freely forage before the age of four months old; when the sows are 4-5 months old, the daily food intake is limited; when the sows are 6-7months old, mating is carried out; a growth period from fertilization of the sows is divided into two stages, wherein the time period from the 1st day to the 59th day is regarded as the first stage, the time period from 60th day to farrowing is regarded as the second stage, and the sows are fed with fodder A and fodder B separately; two weeks before farrowing, rock music is played within a span from 9 a.m. to 11 a.m. and a span from 4 p.m. to 6 p.m. every day, and light music is played within a span from 8 p.m. to 11 p.m. every day; after farrowing, light music is played within a span from 7 a.m. to 10 a.m. a span from 3 p.m. to 5 p.m. and a span from 7 p.m. to 10 p.m. every day; one week after weaning, the lactating sows are subjected to mating again, and the steps above are repeated frommating until the sows are eliminated. The method is environmentally friendly and capable of saving energy, preventing diseases, improving the reproductive performance of the sows and increasing the economic benefits of a pig farm.

Description

technical field [0001] The invention relates to a method for sow breeding. Background technique [0002] Sow feeding is one of the most important links in pig production. Its nutritional status not only directly affects the health and production performance of piglets, but also relates to the reproductive life of sows and the efficiency of pig production. In the modern pig breeding system, prenatal feeding of sows is crucial to the subsequent reproductive performance of sows. At this time, although sows are sexually mature, they have not yet reached physical maturity, and are easily affected by factors such as diseases, management and feeding, resulting in production performance. low. The level of reproductive performance of sows directly affects the production performance of commercial intensive pig farming. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a method for breeding sows, which can improve the ...
