Patterned breeding method and feed for improving sow reproduction performance

Abstract

The invention belongs to the technical field of breeding, and particularly relates to a patterned breeding method jointly using pregnant sow compound feed of alfalfa and lactating sow compound feed toimprove sow reproduction performance. The method mainly includes: managing breeding in the pregnant period; managing breeding in the lactating period; management on breeding in the pregnant period ischaracterized in that optimal temperature is 16-23 DEG C, daily water intake is 10-15L, and a certain amount of pregnant sow compound feed is fed at different stages of pregnancy; management on breeding in the lactating period is characterized in that optimal temperature is 18-22 DEG C, daily water intake is 20-30L, and a certain amount of lactating sow compound feed is fed at different stages oflactating. By using alfalfa granules, reproduction performance of sows can be improved; fat content in colostrum and ordinary milk are increased, and growth and survival of newborn piglets are facilitated. Different methods are adopted for preparation according to characteristics of raw materials, and action of each raw material can be brought into maximum play, so that farrowing and health of suckling pigs are benefitted.

Description

technical field [0001] The invention belongs to the field of breeding technology, and in particular relates to a modeled feeding method for feeding sows by combining compound feed for pregnant sows using alfalfa and compound feed for lactating sows to improve the reproductive performance of sows. Background technique [0002] In order to improve the efficiency of breeding in the pig industry, it is necessary to increase the production capacity of sows, that is, to increase the number of piglets provided by sows per year, so the health of sows is especially important. In the practice of raising pigs, sows are often in a state of constipation. Long-term constipation in sows often causes pregnancy failure during pregnancy, and it is the most important cause of agalactia syndrome during lactation. Therefore, the health of the sow herd is primarily concerned with gut health. [0003] In order to protect the intestinal health of sows, the choice of fiber component raw materials i...

Problems solved by technology

[0009] Publication number: 105995056A's invention "A Lactic Acid Bacteria Propagation Process Based on Alfalfa Green Storage Fermentation" is a lactic acid bacteria propagation process based on alfalfa green storage fermentation, which mainly solves the problem that the current alfalfa grass cannot be successfully fermented in green storage and the protein content of milk is difficult. To improve the problem, the present invention provides a process for the propagation of lactic acid bacteria based on the fermentation of alfalfa green storage. First, the alfalfa green storage is fermented to obtain fermented alfalfa, and then the lactic acid bacteria are multiplied. The step of multiplication is to After the fermented alfalfa is kneaded and processed, it is fully stirred with cornmeal, then granulated to obtain alfalfa granules, and then mixed with Leymus chinensis to obtain a complete mixture, and finally the complete mixture is put into a plastic bag lined with film , packed in airtight bags to obtain a full mixture of lactic acid bacteria

[0010] Alfalfa is rich in nutrients. For convenience, many manufacturers process alfalfa into alfalfa granules. However, because alfalfa is not easy to digest and has a strong astringent taste, it is usually used to feed ruminants such as cattle and sheep, mainly dairy cows. consume
