摘要
研究了2种不同饲养方式(常规饲养和测定站饲养)对杜洛克猪生长性能及胴体肉品质的影响。结果表明:常规饲养的杜洛克猪的料重比、胴体瘦肉率,肌肉L、b、L_(24)、a_(24)、b_(24)值,背最长肌中胱氨酸、蛋氨酸、酪氨酸和苯丙氨酸含量,肌肉硬脂酸和亚油酸含量均比测定站饲养的杜洛克猪高;而测定站饲养的杜洛克猪的胴体重、屠宰率、平均背膘厚、皮脂率、肉色、24 h大理石纹、肌纤维直径、肌内脂肪含量、肌肉鲜味氨基酸占氨基酸总量的比例、肌肉棕榈酸和油酸含量均比常规饲养的杜洛克猪高。
The effects of two different feeding methods (regular feeding, and feeding in testing station) on the growth per- formance and meat quality of Duroc were studied. The results indicated that the Durocs fed by using regular feeding method had higher feed-weight ratio, carcass lean meat rate, values of L, b, L24, a24 and b24 of muscle, contents of eystine, methionine, tyrosine and phenylalanine in longissimus dorsi, and contents of stearic acid and linoleie acid in muscle than those fed in testing station; while the Durocs fed in testing station had higher carcass weight, dressing percentage, average fatback thickness, skin- fat percentage, meat color score, 24-h marbling score, muscle fiber diameter, intramuscular fat content, ratio of flavor amino acid content to total amino acid content in muscle, and contents of palmitinic acid and oleic acid in muscle than those fed by using regular feeding method.
