摘要
该试验旨在探索不同育肥期对松潘藏猪生长性能及肉品质的影响.选用3月龄体重相近的松潘藏猪24头,随机分为试验组和对照组,测定生长性能及肉品质相关指标.结果表明,全期头均日增重试验组相比对照组下降7.20%(P＜0.05).全期料重比试验组比对照组下降42.13%(P＜0.01).对照组的屠宰率、背膘厚和眼肌面积分别比试验组高8.26%(P＜0.05)、29.43%(P＜0.01)和7.58%(P＞0.05).与对照组相比,试验组水分、粗灰分和粗蛋白分别增加1.97%(P＞0.05)、4.32%(P＞0.05)和9.54%(P＜0.05),肌内脂肪下降13.28%(P＜0.05).在该试验条件下,松潘藏猪按传统"放牧+半舍饲"育肥方式,以育肥360 d(15月龄)左右完成育肥屠宰可取得较好的生长效率及肉品质.
Abstract
To explore the effects of different fattening period on the growth performance and meat quality of Songpan Tibetan pigs.Methods:24 Songpan Tibetan pigs of the same weight at the age of 3 months were randomly divided into experimental group and control group.The growth performance and meat quality were measured.Results:the full-term daily gain of the test group was 7.20%lower than that of the control group(P＜0.05).The full-term feed weight ratio was 42.13%lower than that in the control group(P＜0.01).The slaughter rate,fat thickness and eye muscle area of the control group were 8.26%(P＜0.05),29.43%(P＜0.01)and 7.58%(P＞0.05)higher than those of the test group,respectively.The water content,crude ash and crude protein of the test group were higher than those of the control group by 1.97%(P＞0.05),4.32(P＞0.05)and 9.54%(P＜0.05),and the intramuscular fat of the test group was lower than that of the control group by 13.28%(P＜0.05).Conclusion:Songpan Tibetan pigs can achieve better growth efficiency and meat quality by fattening and slaughtering for about 360 days(15 months)according to the traditional"grazing + semi house feeding"fattening method.
