Abstract

Background: Lysine is used widely in livestock production due to the shortage of feed protein resources. -lysine·HSO contains -lysine sulphate as well as fermentation co-products which contain other amino acids and phosphorus. However, there are few articles about -lysine·HSO product regarding intestinal morphology and liver pathology of broiler chickens. In this article, we focus on the absorption and metabolism of -lysine·HSO revealed in the variation of intestinal morphology and liver pathology to determine the tolerance of chicks for -lysine·HSO.

Methods: To evaluate the tolerance of broilers for -lysine·HSO, 240 one day old broilers were allocated randomly to one of five dietary treatments which included corn-soybean diets containing 0, 1%, 4%, 7% or 10% -lysine·HSO (-lysine content = 55%).

Results: Supplementation of 1% -lysine·HSO in the diet had no negative effects. However, 4%, 7% or 10% -lysine·HSO supplementation produced negative responses on broiler performance, carcass characteristics, blood biochemistry, and particularly on intestinal morphology and liver pathology compared with broilers fed the control diet.

Conclusion: Our results show that supplementation with 1% -lysine·HSO had no negative effects on performance, carcass characteristics, blood biochemistry, intestinal morphology and liver pathology in broilers, but supplementation with 4%, 7% or 10% -lysine·HSO produced a negative response, particularly with respect to intestinal morphology and liver pathology.
