Effects of Dietary Sodium Stearyl Lactate Supplementation on Growth Performance, Serum Biochemical Indices and Nutrient Apparent Digestibility of Weaning Piglets
摘要
Abstract
This experiment was conduct to study the effects of dietary sodium stearyl lactate (SSL) supplementation on growth performance, serum biochemical indices and nutrient apparent digestibility of weaning piglets.A total of 336 weaning piglets with 25 days old were randomly assigned to 6 groups with 7 replicates each and8 piglets in each replicate by body weight.The supplemental levels of SSL in diets of 6 groups were 0 (control), 250, 500, 750, 1 000 and 2 000 mg/kg, respectively.The whole experiment was divided into two phases with 21 days each.Growth performance, the activities of alanine transaminase (ALT) and aspartate aminotransferase (AST), total cholesterol content, as well as the apparent digestibility of nitrogen, crude fat, energy and dry matter were measured in this experiment.The results showed as follows: compared with control group, 1) dietary supplementation of 500, 750 and 1 000 mg/kg SSL significantly decreased the ratio of feed to gain (F/G) of pigs in phase 2 (P<0.05), and dietary supplementation of 1 000 mg/kg SSL significantly decreased F/G around the total phase (P<0.05).2) Dietary supplementation of SSL showed a tendency to decrease the activities of AST and ALT, and increase the high density lipoprotein cholesterol and the ratio of high density lipoprotein cholesterol to low density lipoprotein cholesterol, while to reach a significant level at2 000 mg/kg (P<0.05).3) The crude fat apparent digestibility was significantly increased by SSL supplementation (P<0.05) and the apparent digestibility of energy and nitrogen was also enhanced especially when the supplemental level up to 2 000 mg/kg (P<0.05).In conclusion, dietary supplementation of SSL decreases the F/G and increases nutrient apparent digestibility especially the digestibility of crude fat of piglets.[Chinese关键词
