Effects of iron-gly on the production performance of weaned piglets
In order to study the effect of growth performance of weanling piglets on basal diet addition 50 mg/kg (including ferrous iron) iron-gly, 72 weaned piglets are selected to be randomly divided into 3 groups, Every group sets up 3 repetitions, and 8 piglets in each repetition. For experiment, there are contrast group Ⅰ (basic diet including 100 mg/kg inorganic iron), contrast group Ⅱ (basal diet addition 50 mg/kg inorganic iron), test group (basal diet addition 50 mg/kg iron-gly). Test results showed that more over contrast group Ⅰ and Ⅱ, not significant difference, the daily gain of the test group is 2.67% (P>0.05) and 2.18%(P>0.05); in feed/gain rate, there is a large difference between test group and contrast group Ⅰ , but a small difference between test group and contrast Ⅱ , feed/gain rate decreases by 1.4%(P<0.05) and 0.7%(P>0.05)over contrast Ⅰ and Ⅱ; the experimental group and control group I significantly different (P<0.05), and the control group Ⅱ was not significantly (P>0.05). Breeding rate was not significant difference between the three groups, in diarrhea rate, diarrhea rates compared with the control group I and Ⅱ decreased 93.3% and 83.3%; Serum microelement iron trend of increase are higher than the control group Ⅰ and control group Ⅱ. But the group of differences are not significant (P>0.05); the test group of weanling piglets,excretion is 30.02%(P<0.01 )and 30.47%(P<0.01); But the control group Ⅰ and Ⅱ was not significant difference between the control group (P>0.05). Therefore, in basal diet addition 50 mg/kg (including ferrous iron) iron-gly, Not only can improve the growth performance of weanling piglets, still can reduce excretion microelement iron emissions.
