AI Technical Summary

Technical Problem

Pregnant sows and lactating sows face problems such as unreasonable feed nutritional structure, low synchronous estrus rate, fluctuating production performance, and inadequate management, which lead to sows being too fat or too thin, an increase in the number of weak piglets, and low birth weight of piglets. Hormone and antibiotic interventions have drug resistance and safety issues.

Method used

A composition of laurel leaf extract, rosemary extract, serine, N-aminoformylglutamate and probiotics is used as a feed additive to improve the nutritional intervention of sows, enhance the nutritional and immune transmission of breast milk, and improve the reproductive and lactation performance of sows.

Benefits of technology

Significantly improve the estrus rate, conception rate, number of piglets, and lactation performance of sows, enhance the health of piglets, increase litter weight at birth and weaning weight, increase sow feed intake and pig milk quality, and improve sow production performance and economic benefits.

Abstract

The invention discloses a feed additive for improving reproduction and lactation performance of sows in the late pregnancy-lactation period. The feed additive is composed of the following components in parts by weight: 1-4 parts of a cinnamon leaf extract, 1-4 parts of a rosemary extract, 10-20 parts of serine, 10-20 parts of N-carbamylglutamic acid, 40-60 parts of a probiotic composition and 10-20 parts of wheat bran. The probiotic composition is prepared from the following bacteria: 1.5 * 10 < 13 > to 4.5 * 10 < 13 > CFU / kg of bacillus subtilis, 1.5 * 10 < 13 > to 4.5 * 10 < 13 > CFU / kg of bacillus coagulans, 4 * 10 < 12 > to 6 * 10 < 12 > CFU / kg of clostridium butyricum and 5 * 10 < 12 > to 7 * 10 < 12 > CFU / kg of bacillus licheniformis.
