Effects of Supplementary Feeding Fermented Asparagus By-Product on Fecal Morphology and Milk Quality of Sows
摘要
Abstract
This study was conducted to investigate the effects of supplementary feeding fermented asparagus by-product on fecal morphology and milk quality of sows from late-pregnancy to the end of lactation.Fifteen pregnant sows with similar body condition,parity and parturition time were randomly assigned to groups Ⅰ,Ⅱ and Ⅲ,respectively,with five replicates each and one sow in each replicate.Each sow was fed a basal diet supplemented with 0,0.25 and 0.50 kg fermented asparagus by-product each day in three groups,respectively.The experiment lasted from day 85 after pregnancy to day 21 after delivery.The results showed as follows:1) fecal morphology was improved by the supplementation of fermented asparagus by-product to sows.2) The levels of milk protein,growth hormone,insulin and immunoglobulin G in colostrum of group Ⅲ were significantly higher than those of group Ⅰ (P＜0.05),tumor necrosis factor-α level in colostrum of group Ⅲ was significantly lower than that of group Ⅰ (P＜0.05).3) Total superoxide dismutase activity in milk collected from groups Ⅱ and Ⅲ was significantly higher than that of group Ⅰ (P＜0.05) at day 10,and which extremely significantly higher than that of group Ⅰ at day 21 (P＜0.01);the levels of malondialdehyde,interleukin1β,interleukin-6 and tumor necrosis factor-ct in milk collected from group Ⅲ at day 21 were significantly lower than those of group Ⅰ (P＜0.05).It is concluded that supplementary feeding fermented asparagus by-product to sows can reduce the constipation rate of sows from late-pregnancy to the end of lactation and improve milk quality of sows in different degrees.关键词
