摘要:

本试验旨在研究复合氨基酸络合铁、锌对肥育猪生产性能、屠宰性能、血液生化指标、肝和肌肉铁、锌含量的影响。试验选择初始体重相近((55.63±1.33) kg)的杜×长×大育肥猪36头,随机分为3个组,每个组3个重复,每个重复4头猪,公母各半,饲养期8周。对照组饲喂铁、锌含量均为100 mg·kg-1(由硫酸亚铁、硫酸锌提供)的基础日粮,试验1组饲喂铁、锌含量均为50 mg·kg-1(由硫酸亚铁、硫酸锌提供)+50 mg·kg-1(由氨基酸络合铁锌提供)的基础日粮,试验2组饲喂铁、锌含量均为100 mg·kg-1(由氨基酸络合铁锌提供)的基础日粮。结果表明,试验2组的末重、平均日增重、体斜长、体直长、总蛋白、肝和肌肉铁含量均显著高于对照组(P<0.05),血清铁和锌显著高于对照组和试验1组(P<0.05),料重比显著低于对照组(P<0.05)。结果提示,日粮中添加复合氨基酸络合铁、锌各100 mg·kg-1可提高肥育猪的生产性能,降低料重比,最终提高饲料转化效率。

Abstract:

This experiment was conducted to study the effect of iron and zinc complex amino acid chelate on growth performance,carcass traits,blood biochemical indexes,iron and zinc content in liver and muscle in finishing pigs.Thirty six hybrid fatten pigs with average initial body weight of ((55.63±1.33)kg) were selected and randomly allotted to three dietary treatments.There were three replicates per treatment and four pigs in each replicate.The feeding trial lasted for 8 weeks.Pigs in the control group were fed the basic ration with 100 mg·kg-1 iron,zinc (which were offered by ferrous sulfate and zinc sulfate).Pigs in experimental group 1 were fed the basic ration with 50 mg·kg-1 iron,zinc (which were offered by ferrous sulfate and zinc sulfate) and 50 mg·kg-1 iron,zinc(which were offered by organic elements).Pigs in experimental group 2 were fed the basic ration with 100 mg·kg-1 iron,zinc (which were offered by organic elements).The results showed that pigs in experimental group 2 had higher final weight,average daily gains,body oblique length,body straight length,total protein,iron in liver and muscle than those in control group(P<0.05).Iron and zinc in serum in experimental group 2 were significantly higher than that in control group and experimental group 1(P<0.05),feed conversion ratio was significantly lower than that in control group (P<0.05).These results indicate that iron and zinc complex amino acid chelate can improve growth performance in finishing pigs,enhance feed conversion ratio,finally,improve feed conversion efficiency.
