Effects of Trace Mineral Amino Acid Chelates on Growing Pigs
Performance and nutrients availability
Abstract: 48 crossbreed(Duroc×Landrace×Yordshire) growing pigs of average weight of 28kg were randomly divided into 4 groups, 3 replicates per group. Trace mineral levels of 0%,25%,50% and 75% were substituted by mineral amino acid chelates. The trial results of 56 days showed that the average daily gain and Feed efficiency of group B were significantly higher than those of group A(P<0.05); However, no significant difference was found in concentration of Fe, Zn, Cu, Mn in serum among 4 groups(P>0.05); Concentration of Fe, Zn, Cu in feces of B,C,D group were all significantly lower than those of group A(P<0.05). Therefore, feed growing pig with mineral amino acid chelates fodder instead of inorganic mineral fodder, could significantly improve production performance and digestibility of crude protein of fodder.
Save material. Increase output. Decrease the ratio of feed to meat and the ratio of feed to egg. layer can save feed 8%.
With protein hydrolysate aroma and flavor, strong palatability.
layer and dairy cattle can extend period of growth 1-2 months. chicken can column one week earlier, Pigs can column 10 days earlier.
To improve the fertilization rate, hatching rate, birth rate, to increase pig each birth 2-3 babys more, survival rate increase from 90% to 98%.
Significantly reduce the laying hens feather pecking anal phenomenon.
To prevent or alleviate chicken diarrhea, egg color good-looking, egg weight increased. Pigs are with oily hair color after feed, like to sleep than move.
