摘要
文章旨在探究日粮添加腐殖酸钠(Sodium humate,HNa)对育肥猪生产性能、抗氧化性能和气体排放的影响.试验选择初始重(65.23±1.34)kg的"杜长大"外三元杂交猪 300 头,随机分为 5 组,每组 6 个重复,每个重复 10头猪.空白(Blank)组饲喂基础日粮,试验组在基础日粮中添加 0.25%(HNa1 组)、0.50%(HNa2 组)、0.75%(HNa3 组)和 1.00%(HNa4 组)的HNa.试验为期 63 d,预饲期 4d.结果表明:与Blank组相比,育肥猪日粮中添加 0.75%、1.00%的HNa可显著提高终末重(FBW)、平均日增重(ADG),显著降低料重比(F/G)(P＜0.05);与Blank组相比,育肥猪日粮中添加 1.00%的HNa,血清总抗氧化能力、谷胱甘肽过氧化物酶及超氧化物歧化酶(SOD)指标显著升高(P＜0.05),丙二醛(MDA)指标极显著下降(P＜0.01);与Blank组相比,育肥猪日粮中添加 0.75%、1.00%的HNa可显著降低猪氨气、硫化氢、甲烷的气体排放量(P＜0.05).综上所述,育肥猪日粮中添加 0.75%的HNa可显著提升其生产性能,优化气体排放指标,添加量为 1.00%时猪的抗氧化性能更好.
Abstract
The study was designed to research the effects of dietary sodium humate(HNa)supplementation on production performance,antioxidant capacity and gas emission of finishing pigs.A total of 300"D×L×Y"foreign crossbred pigs with an initial weight of(65.23±1.34)kg were randomly divided into 5 groups,with 6 replicates per group and 10 pigs per replicate.Blank group was fed with basal diet,experimental groups were supplemented with 0.25%(HNa1 group),0.50%(HNa2 group),0.75%(HNa3 group)and 1.00%(HNa4 group)HNa in basal diet.Experiment lasted for 63 days,pre-experiment lasted for 4 days.The results showed as follows:compared with Blank group,adding 0.75%and 1.00%HNa in the diet of finishing pigs significantly increased final weight(FBW),average daily gain(ADG),and significantly decreased the ratio of feed to gain(F/G)(P＜0.05);Compared with Blank group,the serum total antioxidant capacity,glutathione peroxidase and superoxide dismutase(SOD)indexes of finishing pigs supplemented with 1.00%HNa were significantly increased,and malondialdehyde(MDA)index was very significantly decreased(P＜0.01).Compared with Blank group,adding 0.75%and 1.00%HNa in the diet of finishing pigs could significantly reduce the gas emissions of ammonia,hydrogen sulfide and methane(P＜0.05).In conclusion,adding 0.75%HNa to the diet of finishing pigs can significantly improve production performance and optimize gas emission index,and the antioxidant capacity of pigs is better when adding 1.00%HNa.
