不同月龄南充黑山羊的屠宰性能及肉质性状研究
Study on slaughter performance and meat quality characteristics of Nanchong black goats at different months of ages
摘要
Abstract
This experiment aimed to investigate the slaughter performance and meat quality characteristics variation patterns of Nanchong black goats at different months of age.Eighteen goats of varying ages were selected,and their growth performance,slaughter performance,meat quality,processed mutton attributes,and sensory qualities were measured across developmental stages.The results showed that with increasing age,body weight,body length,height,chest circumference,carcass weight,meat yield,and bone weight significantly increased(P＜0.05),while slaughter rate and meat percentage demonstrated upward trends.Between 6 and 24 months of age,the slaughter rate improved from 39.57%to 54.37%,meat percentage increased from 31.61%to 42.54%,and the meat-to-bone ratio rose from 4.03 to 4.42.At 12 months of age,the meat exhibited higher crude protein and fat content,bright red color,tender texture,and mild odor.The longissimus dorsi muscle received the highest sensory evaluation score(90.50 points),but also showed the greatest drip loss in the dorsal region.The fast-to-slow twitch muscle fiber ratio decreased with advancing age.Although 24-month-old goats achieved the highest slaughter rate,their meat tenderness and texture declined.The study indicates that 12-month-old Nanchong black goat meat exhibits optimal quality characteristics,making it most suitable for production and market distribution.关键词
