Study on Meat Quality Traits for Yunnan Black Goat
摘要
Abstract
The main nutrients ingredient,amino acids and fatty acid content of the longest muscle in the 6-month-old and 12-month- old Yunnan black goat under drylot feeding were measured and analyzed. The results showed that the moisture,crude fat,crude protein and ash of 6-month-old lamb meat were 75.07%,2.03%,21.53% and 1.06% respectively;while those of 12-month-old lamb meat were 75.40%,0.97%,21.03% and 1.00% respectively. Secondly,the mutton of 6-month-old and 12-month-old lamb were rich in minerals and vitamins,but low in cholesterol. Thirdly,the kinds and content of amino acids were rich,there were 17 kinds of amino acids and the total contents were 17.11 g/100g and 16.93 g/100g in the mutton of 6-month-old and 12-month-old lambs respectively. The fresh amino acids were also rich in content and accounted for 45.00% and 45.30% of the total amino acids in the mutton of 6-month-old and 12-month-old lambs respectively. Finally,the fatty acid content of 6-month-old mutton was more than that in the 12-month-old mutton,and the most of the fatty acid content between two ages reached a significant difference(P<0.05)or extremely significant difference(P<0.01). The main components of fatty acids were palmitate,stearic acid,trans-oleic acid and linoleic acid,and the four kinds of fatty acids accounted for 76.41% and 73.43% of the total fatty acids in the mutton of 6-month-old lambs and 12-month-old lambs respectively. The 6-month-old lamb meat was rich in linoleic acid,which was 1200.50 mg/kg. There were three kinds of branched chain fatty acid,and they were 6.28 mg/kg and 8.66 mg/kg in the mutton of 6-month-old lamb and 12-month-old lamb respectively.关键词
