Embodiment 1

[0012] A method for managing lactating sows, specifically comprising the following steps:

[0013] (1) 1-5 days after the sows give birth, keep the pig house clean and free from peculiar smell, reduce the temperature of the pig house to 20-22°C, increase the light for 90 minutes every day, and the light intensity is 450lx, and then light the sows. Add additive in the feed, the consumption of described additive is 0.1% of feed weight, and described additive is made after mixing by nano activated carbon, Chinese medicine powder, sodium citrate, honey by mass ratio 8:30:1:5;

[0014] (2) 6-15 days after the sows give birth, adjust the temperature in the pig house to 30-35°C, and the shade degree to 55-60%. At the same time, increase the protein content in the sow feed to 22%, and reduce the crude fiber content to 12%;

[0015] (3) The piglets can be weaned early 20 days after the sows give birth, and then the sows can be stimulated to estrus by conventional methods.

Embodiment 2

[0018] (1) 1-5 days after the sows give birth, keep the pig house clean and free from peculiar smell, lower the temperature of the pig house to 20-22°C, increase the light for 120 minutes every day, and the light intensity is 600lx, and then light the sows. Add additive in the feed, the consumption of described additive is 0.15% of feed weight, and described additive is made after mixing by nano activated carbon, Chinese medicine powder, sodium citrate, honey by mass ratio 8:30:1:5;

[0019] (2) 6-15 days after the sows give birth, adjust the temperature in the pig house to 30-35°C and the shade degree to 55-60%. At the same time, increase the protein content in the sow feed to 8%, and reduce the crude fiber content to 15%;

[0020] (3) The piglets can be weaned early 20 days after the sows give birth, and then the sows can be stimulated to estrus by conventional methods.

[0021] Further, the traditional Chinese medicine powder in step (1) is prepared by washing, drying, and...

Abstract

The invention discloses a management method of lactation-period sows. The management method includes the steps of firstly, using a management method for the sows 1-5 days after farrowing; secondly, using a management method for the sows 6-15 days after the farrowing; thirdly, performing early-stage weaning on piglets 20 days after the farrowing. Experiments show that by the management method, the annual litter number of the sows is increased from conventional 2.4 litter / year to 2.7 litter / year, piglet number of each litter is increased from conventional 10.1 / litter to above 10.5 / litter, the economic benefits of farmers are increased greatly, and the method is worthy of popularization and use.

Description

technical field [0001] The invention belongs to the field of breeding technology, and in particular relates to a management method for lactating sows. Background technique [0002] Piglets in traditional pig breeding have a long lactation period, and are generally weaned at 56-60 days after birth. The average annual litter per sow is only 1.6-1.8 litters. In recent decades, experts and scholars from various countries have been studying how to improve the fecundity of sows through early weaning of piglets, reduce the number of breeding sows, and reduce the cost of feeding, so as to obtain good economic benefits. However, improper management of sows during lactation will lead to a delay in estrus time, which will seriously affect the annual litter size and litter size of sows. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for increasing litter size of sows. [0004] The present invention is achieved through...
