多菌种发酵稻壳粉对母猪采食量、生产性能和血清激素的影响

皆在探讨发酵稻壳粉(FRH)和稻壳粉(RH)对母猪繁殖性能、血液激素水平、采食量和泌乳量的影响。选择胎次一致的(长×大)母猪33头,随机分为3组,每组11个重复,每个重复1头猪。对照组饲喂基础日粮,FRH组和RH组分别补饲20%的FRH和RH。结果显示:FRH组和RH组母猪窝总产仔数、产活仔数、健仔数、产程、断奶活仔数和21日龄断奶窝重均显著高于对照组(P<0.05)。FRH组仔猪初生窝重显著高于RH组(P<0.05)。血清孕酮(PROG)水平:母猪妊娠21 d,FRH组和RH组均显著高于对照组(P<0.05);血清雌二醇(E2)浓度:母猪妊娠21 d,FRH组显著高于对照组和RH组(P<0.05);各组血清催乳素(PRL)浓度差异不显著(P>0.05)。FRH组哺乳期采食量和母猪产奶量均显著高于对照组和RH组(P<0.05)。综合各项指标:妊娠母猪基础日粮中补饲20%的FRH可改善母猪的繁殖性能、提高采食量和泌乳量。

The effect of multi-strain fermented rice hull powder on feed intake indicators,production performance and serum hormones of sows

The experiment was conducted to study the effects of fermented rice hull powder on feed intake indicators,production performance and serum hormones of sows.Tirty-three healthy sows with the same parity(4 parity Landrace×Large white) were randomly selected and divided into 3 groups of 11 each.The control group was fed with basic diet,FRH and RH groups were supplemented with 20% FRH and RH,respectively.The results showed that the total litter size,the number of live births,the number of healthies,production process,number of live weaned offspring and 21-day-old litter weight of FRH and RH groups were significantly higher than those in the control group(P<0.05).Birth litter weight of piglets of FRH group were significantly higher than that of RH group(P<0.05).Serum progesterone(PROG) level of FRH and RH groups were significantly higher than that in the control group on 21 days of gestation(P<0.05);serum estradiol(E2) concentration of FRH group was significantly higher than that in the control and RH groups on 21 days of gestation(P<0.05);there was no significant difference of serum prolactin(PRL)concentration among groups(P>0.05).The feed intake during lactation and milk yield of sows of FRH group was significantly higher than that of the control and RH groups(P<0.05).On the conclusion that replenishment of 20% FRH in the basic diet of pregnant sows can improve reproductive performance,feed intake and lactation of sows.
