Effects of Liquid Feeding with Graded Replacement of Diet with Fermented Sauce-Flavor Distillers' Grains and Grain Distillers' Syrup on Growth Performance,Carcass Traits,and Meat Quality of Duroc×Landrace×Yorkshire Finishing Pigs
摘要
Abstract
[Objective]To investigate the effects of graded replacement of the diet of fermented sauce-flavor distillers'grains and grain distillers' syrup with liquid feeding on the growth performance,carcass traits,and meat quality of Duroc×Landrace×Yorkshire finishing pigs,aiming to provide data support and practical strategies for their efficient and safe application in pig production.[Methods]A total of 80 healthy Duroc×Landrace×Yorkshire barrows were randomly assigned to two groups,with four replicates per group(four independent feeding units)and ten pigs per replicate.The trial period was 77 day and was divided into two stages:early stage(days 1-49)and late stage(days 50-77)with graded replacement feeding.The control group was fed a basal diet throughout both stages;the experimental group received a diet in which 6%fermented sauce-flavor distillers' grains+6%grain distillers' syrup replaced the basal diet in equal amounts in the early stage,and 9%fermented sauce-flavor distillers'grains+8%grain distillers' syrup replaced the basal diet in the late stage.A liquid feeding system was utilized throughout the trial.At the end of the trial,growth performance indicators,carcass trait indicators,organ indices,and meat quality indicators of Duroc×Landrace×Yorkshire finishing pigs were measured.[Results]Compared with the control group,the experimental group showed a significant increase in the average daily gain(P＜0.05)and an extremely significant decrease in the feed-to-gain ratio(P＜0.01)during the overall period;the fat percentage in the experimental group increased significantly(P＜0.05),the lean meat percentage decreased significantly(P＜0.05),and the loin eye area decreased extremely significantly(P＜0.01),while no significant differences were observed in other carcass traits(P＞0.05);no significant differences were detected in organ indices or meat quality(P＞0.05).[Conclusion]Under the conditions of this experiment,replacing the basal diet with graded proportions of fermented sauce-flavor distillers' grains and grain distillers' syrup had no negative effects on the growth performance,carcass traits,organ indices,or meat quality of Duroc×Landrace×Yorkshire finishing pigs,and improved the growth performance of finishing pigs.However,attention should be paid to the decrease in lean meat percentage.关键词
