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.
