摘要:

本试验旨在探索不同硒源及硒水平对断奶仔猪生长性能、血清抗氧化能力和血浆硒含量的影响。选用600头平均体重为(8.50±0.52)kg、平均日龄为(28±3.5)d的杜长大三元杂交仔猪,随机分成10组,每组3个重复,每个重复20头仔猪,分别饲喂不同处理的日粮。1组为对照,饲喂不添加硒源的日粮,其余9组为试验组,分别以亚硒酸钠、酵母硒和纳米硒的形式添加到0.30.50.7 mg·kg-1 3个水平的硒,试验期46 d。试验结果表明:①不同硒源及添加水平对仔猪平均日采食量影响不显著(P>0.05);与对照组相比,0.30.5 mg·kg-1硒水平的纳米硒和0.5 mg·kg-1硒水平的酵母硒显著提高仔猪日增重(P0.05);0.5 mg·kg-1硒水平的纳米硒仔猪日增重显著高于0.7 mg·kg-1硒水平的亚硒酸钠(P0.05);②不同硒源及添加水平对仔猪血浆硒含量影响不显著(P>0.05);③不同硒源及添加水平对仔猪血清MDA含量影响不显著(P0.05),0.5 mg·kg-1硒的纳米硒和0.5 mg·kg-1硒的酵母硒血清T-AOC含量显著高于对照组(P0.05),0.5 mg·kg-1硒的纳米硒血清GSH-PX含量显著高于对照组(P0.05)。

Abstract:

The objectives of this study were to investigate the effects of different sources and supplemental dosages of selenium on the piglets growth performance, plasma selenium content and anti-oxidative activities and antioxidant capacity; Three different sources of selenium: Sodium Selenite, Nano-selenium and Selenium Yeast and three dietary supplemental levels at 0.3, 0.5 and 0.7 mg·kg-1 were used. The piglets fed on a basal diet without external Se sources were used as control group. Six hundreds healthy D×LW×L hybrid piglets at the age of (28±3.5) days, and average initial body weight ((8.50±0.52) kg) were divided into 10 groups with 3 replicates each group and 20 piglets (10 males and 10 females) per replicate and fed with the experimental diets. The trial lasted for 46 days. The results were as follows: The difference was not significant in the average daily feed intake of the piglet fed different selenium sources (P>0.05), but the daily gain in the 0.3 and 0.5 mg·kg-1 nano-selenium groups and 0.5 mg·kg -1 yeast selenium group was significantly higher than that in control group (P<0.05), and 0.5 mg·kg-1 nano-selenium group was significantly higher than that in 0.7 mg·kg -1 sodium selenite group (P<0.05). The difference was not significant in plasma selenium content of the piglet fed different selenium sources (P>0.05). The difference was not significant in the serum MDA level of piglet fed different selenium sources (P>0.05), the serum-AOC level in the 0.5 mg·kg-1 nano-selenium and 0.5 mg·kg-1 yeast selenium groups were significantly higher than that in control group(P<0.05), and the GSH-PX levels in 0.5 mg·kg-1 nano-selenium group was significantly higher than that in the control group (P<0.05).

Key words: selenium, piglet, growth performance, selenium content, antioxidant capacity
