Effects of Dietary Lactobacillus Feed Additives on Growth Performance, Meat Quality and Flavor Compounds of Finishing Pigs
摘要
Abstract
This experiment was conducted to evaluate the effects of dietary Lactobacillus feed additives on the performance and meat quality in finishing pigs.A total of 240 three-crossed pigs (Duroc×LargeWhite× Landrace) weighing (55±2) kg were randomly assigned to 3 dietary treatments with 4 replications per treatment and 20 pigs per replication for 57 d.Three experimental diets were formulated based on corn-soybean meal,containing 0 (control group),0.3％ dry powder and 0.3％ liquid of microbial feed additives,respectively (The content of Lactobacillus is 1.2× 109 CFU/g).At the end of the test,two pigs (1 barrow and 1 gilt,weight of the selected pigs closely representing the mean replicate weight) from each replicate were sacrificed for sample collection.Supplementation of Lactobacillus feed additives in finishing pig diets could numerically improve the average daily gain,average daily feed intake and feed to gain ratio (P＞0.05).No difference was observed in carcass straight long,carcass inclined long,back fat,skin thick and marbling grading area of among three treatments (P＞0.05).For meat quality,there were no significant difference about meat color,marbling,pH value,drip loss and tender degrees of longissimus dorsi muscle among different treatments (P＞0.05);Compared with control group,the concentrations of hypoxanthine in longissimus dorsi muscle was significantly decreased when pigs fed the diet supplemented with liquid of microbial feed additives (P＜0.05),but there were no effects of the dietary Lactobacillus feed additives in the contents of inosinic acid,glutamate and intramuscular injection fat in longissimus muscle (P＞0.05).Collectively,these results suggested that supplementation of Lactobacillus feed additives in finishing pig diet could improve pork flavor and have no significant effect on growth performance,carcass shape and meat quality.关键词
