How to improve the reproductive performance of sow populatio

The reproductive capacity of pig farms is an important indicator to measure the economic benefits of pig farms. The number of litters per pig per month per year is high, and the survival rate of piglets is high, which will greatly reduce the various costs of pig farm management.

Therefore, how to improve the management conditions and improve the breeding technology at home to improve the reproductive capacity of the sow population?       First, the age structure of sows is mainly determined by the age of the sows. The sow breeding peak of the general pig breeds is 3-8, and the survival rate of piglets is gradually decreased after 9 births. Therefore, the sows are 4-5 years old.

In the year, sows with higher productivity can be appropriately extended, while those with lower productivity are eliminated as early as possible to avoid increasing the burden on the farm.

In addition, sows from breeding to piglet weaning, as a breeding cycle, as an important indicator to measure the fecundity of sows, mass production practices have proved that as long as the farm can catch early piglets and strengthen the feeding management of lactating sows The sow's estrus ovulation and other reproductive performance have not been significantly affected, and at the same time, do a good job of timely estrus to ensure that the conception rate can reach 100%.

Finally, colostrum is an indispensable food for piglets. After birth, piglets should eat colostrum in time, and fix the nipples. The piglets with strong constitution are placed behind to help compensate for growth and improve the growth uniformity of piglets.

In addition, the nutritional needs of piglets are gradually increased about 21 days after the birth of the piglets. In the production, the piglets should be fed 7-10 days after birth, and the addition of afforestation in the feed can better maintain the gastrointestinal function of the piglets. To make it enter the childcare period as soon as possible.

Weaned sows have poor physical fitness. In order to protect the normal development of the next embryo, it is necessary to strengthen nutrition in the early stage of pregnancy.

Pay attention to the combination of reasonable amino acid diets, the crude protein reaches 12%, and should meet the demand of vitamins, energy levels can be unchanged, but must strengthen more exercise.      Regarding the boar, you should observe its living habits at ordinary times, adjust the training at any time, prevent climbing and prevent mutual biting. The young boar should cut off the canine teeth after birth, and properly rearrange the animals after weaning.

Improve diet, help digestion, improve reproductive function, usually once in the morning and afternoon, about one hour each time, when the summer is cool, such as morning and evening, winter is warmer at noon.

Finally, in the current aquaculture production process, the pig farm must pay attention to the density of pig breeding, and the health defense work is very important, regular disinfection of the pig farm, as well as guaranteeing piglets, pig lung disease, pig erysipelas, etc.

The vaccine is quarantined, so that every pig is not leaked, and the breeder is trained in professional techniques to master certain observational power.
