摘要

本试验旨在研究饲粮中不同锰添加水平对断奶仔猪生长性能,血清生化指标,跖骨锰、铁含量和锰、铁表观消化率的影响,以确定断奶仔猪饲粮中锰的适宜添加水平.选用28日龄平均体重(9.84±0.85) kg健康断奶仔猪(杜×长×大)160头,随机分为5组,每组4个重复,每个重复8头猪.对照组饲喂基础饲粮,试验组饲粮在基础饲粮中分别添加4、20、40和80 mg/kg锰[以一水合硫酸锰(MnSO4·H2O)形式添加],试验期35 d.结果表明:1)饲粮中锰添加水平对断奶仔猪的平均日增重、平均日采食量、料重比和血清生化指标均无显著影响(P>0.05);2)断奶仔猪跖骨中的锰、铁含量受饲粮锰添加水平的显著影响(P<0.05),并且跖骨中的铁含量随饲粮中锰水平的增加呈线性和二次曲线降低(P<0.05),饲粮中锰添加水平高于4 mg/kg时,跖骨中的铁含量降低;3)饲粮中锰添加水平显著影响粪中锰、铁排出量(P<0.05),当锰添加水平达到80 mg/kg时,铁的表观消化率显著低于对照组(P<0.05).综上所述,饲粮中添加锰没显著改善断奶仔猪的生长性能和血清生化指标,而锰添加水平高于4 mg/kg时,跖骨中的铁含量降低,且随着饲粮锰添加水平的增加,铁的排出量增加;综合本试验指标,断奶仔猪饲粮中锰添加4~20 mg/kg为宜.

Abstract

This trial was conducted to evaluate the effects of manganese supplemental level on growth performance, serum biochemical indexes, metatarsal bone contents of manganese and iron, and apparent digestibility of manganese and iron of weaned pigs, then to find the appropriate supplemental level of manganese. A total of one hundred and sixty healthy weaned pigs (Duroc×Landrace×Largewhite) with an average of (9.84±0.85) kg were randomly divided into 5 groups with 4 replicates in each group and 8 piglets per replicate. The control group was fed a basal diet, and the experimental groups were fed the basal diet supplemented with 4, 20, 40, and 80 mg/kg manganese for 35 days. The results showed as follows: 1) manganese supplemental level had no significant effects on average daily gain, average daily feed intake, the ratio of feed to gain and the serum biochemical indexes of weaned piglets (P>0.05). 2) Manganese supplemental level had significant effects on metatarsal bone contents of manganese and iron (P<0.05), and the content of iron significantly decreased as linear and quadratic with the increase of dietary manganese supplemental level (P<0.05). When manganese supplemental level was above 4 mg/kg, the metatarsal bone content of iron decreased. 3) Fecal output of manganese and iron was significantly increased with the rise of dietary manganese supplemental level (P<0.05), and when manganese supplemental level was above 80 mg/kg, the apparent digestibility of iron was significantly lower than that in the control group (P<0.05). It is concluded that dietary manganese supplemental level can not significantly promote growth performance and serum biochemical indexes, and with manganese supplemental level increasing, the output of iron has increased, and the metatarsal bone content of iron has decreased when manganese supplemental level is above 4 mg/kg. Taking all the indicators into consideration, the suitable dietary manganese supplemental level for weaned piglets is 4 to 20 mg/kg.

Key words： manganese; weaned piglets; bone; apparent digestibility
