摘要:

为研究日粮中不同藜麦添加水平对芦花鸡肉品质、肌肉营养成分及微量元素的影响,选取49日龄健康脱温芦花鸡150只,随机分为5组:不添加藜麦及其副产物的对照组(CK)和添加4%(Q4)、8%(Q8)、12%(Q12)的藜麦籽实(原粮)及12%藜麦糠(QS)的处理组,饲喂75 d后屠宰并取胸肌和腿肌样品,测定肉品质、营养成分和微量元素。结果表明,胸肌Q12组45 min肉色(亮度L*、黄度b*),Q4、QS组剪切力、蒸煮损失、滴水损失及各试验组的失水率均显著低于CK组(P<0.05);Q8、QS组红度a*和QS组熟肉率均显著高于CK组(P<0.05);标准化评分表明Q12组胸肌肉品质最好;腿肌Q4、Q12组亮度L*(45 min、24 h),Q12组黄度b*(45 min)、滴水损失,Q4组剪切力,Q8、Q12、QS组蒸煮损失均显著低于CK组(P<0.05);而Q8、QS组45 min肉色(红度a*)则显著高于CK组(P<0.05);标准化评分结果表明,Q8组腿肌肉品质最好;Q8组胸肌水分、Q4组腿肌粗灰分及各试验组胸肌、腿肌粗蛋白均显著高于CK组(P<0.05);胸肌Q12组铜元素含量,腿肌Q8组钙元素、Q12组锰元素含量均显著高于CK组(P<0.05)。由此可见,日粮中添加藜麦对芦花鸡肉品质、肌肉营养成分、微量元素有一定改善作用,且添加8%藜麦籽实对肉品质改善效果更佳。

Abstract:

To investigate the effects of quinoa supplementation levels on the quality, muscle nutrients and trace elements of Luhua chicken, a total of 150 healthy Luhua chickens at 49-day-old were randomly divided into 5 groups: the control group (CK) without quinoa and its by-products and the treatment group with 4% (Q4), 8% (Q8), 12% (Q12) quinoa seeds (raw grain) and 12% quinoa bran (QS) were fed for 75 days. After slaughter, the samples of chest muscle and leg muscle were taken to determine the meat quality, nutrients and trace elements. The results showed that breast muscle color (brightness L*, yellowness b*) in group Q12 at 45 min, shear force, cooking loss, drip loss and water loss rate in Q4 and QS groups were significantly lower than those in CK group (P<0.05). Redness a* in Q8 and QS groups and cooked meat rate in QS group were significantly higher than CK group(P<0.05). Standardized score showed that Q12 group had the best chest muscle quality.Brightness L* (45 min, 24 h) of leg muscle in Q4 and Q12 groups, yellowness b* (45 min), drip loss in Q12 group, shear force in Q4 group, cooking loss in Q8, Q12 and QS groups were significantly lower than those in CK group (P<0.05). The meat color (redness a*) at 45 min in Q8 and QS groups was significantly higher than that in CK group (P<0.05).Standardized scores showed that Q8 group had the best leg muscle quality.The water content of chest muscle in Q8 group, ash content of leg muscle in Q4 group and crude protein of chest muscle and leg muscle in experimental groups were significantly higher than those in CK group (P<0.05). The copper content in chest muscle Q12 group, the calcium content in leg muscle Q8 group and the manganese content in leg muscle Q12 group were significantly higher than those in CK group (P<0.05). In conclusion, adding quinoa in the diet can improve the quality, nutritional composition and trace elements of chicken, and adding 8% quinoa seeds has a better effect on the improvement of meat quality.

Key words: quinoa, Luhua chicken, meat quality, muscle nutrient composition, trace element, standardized scoring
