【摘要】：壩上長尾雞是河北省唯一被列入《中國畜禽遺傳資源志》的地方家禽品種。為了更好地保護和開發(fā)利用壩上長尾雞資源,本試驗選取相同飼養(yǎng)管理條件下200日齡的該雞種和海蘭褐雞各180只,每組隨機分為5個重復(fù),每個重復(fù)36只。在同一條件下常規(guī)飼養(yǎng),于230日齡每組挑選10只雞屠宰,對肌肉中主要營養(yǎng)成分進行了比較分析。結(jié)果顯示:1)壩上長尾雞肌肉中的粗蛋白質(zhì)和粗脂肪含量與海蘭褐雞相比差異不顯著(P0.05)。2)2個雞種間胸肌、腿肌中的必需氨基酸含量差異不顯著(P0.05);壩上長尾雞肌肉中的呈味氨基酸(谷氨酸、天冬氨酸、甘氨酸和丙氨酸)含量顯著高于海蘭褐雞(P0.05),腿肌中的苦味氨基酸——苯丙氨酸含量顯著低于海蘭褐雞(P0.05)。3)壩上長尾雞腿肌中的不飽和脂肪酸、飽和脂肪酸和總脂肪酸含量顯著低于海蘭褐雞(P0.05);壩上長尾雞腿肌中的花生四烯酸和二十二碳六烯酸含量顯著高于海蘭褐雞(P0.05)。4)壩上長尾雞胸肌中的鎂(P0.01)和鐵(P0.05)含量顯著或極顯著高于海蘭褐雞,腿肌中的鈉(P0.05)、鎂(P0.01)和鐵(P0.05)的含量顯著或極顯著高于海蘭褐雞。由此可見,壩上長尾雞和海蘭褐雞的肌肉均品質(zhì)優(yōu)良,且壩上長尾雞肌肉品質(zhì)優(yōu)于海蘭褐雞。
[Abstract]:Bashang long tail Chicken is the only local poultry variety in Hebei Province listed in genetic Resources of Chinese Livestock and Poultry.In order to better protect and develop and utilize the resources of the long-tailed chicken in Bashang, the experiment selected 180 broilers of 200 days of age and 180 of each of which were randomly divided into 5 replicates with 36 replicates each under the same feeding and management conditions.Under the same condition, 10 chickens were slaughtered in each group at 230 days of age, and the main nutritional components in muscle were compared and analyzed.The results showed that the contents of crude protein and crude fat in the muscle of the long-tailed chicken were not significantly different from those of the Hailan brown chicken (P0.05. 2) the pectoralis muscle of the two breeds was not significantly different from that of the Hailan brown chicken.The content of essential amino acids in leg muscles was not significantly different (P0.05), and the flavor amino acids (glutamic acid, aspartic acid) in the muscle of long-tailed chicken (Glutamic acid, aspartic acid),The contents of glycine and alanine) were significantly higher than that of Hailan Brown Chicken, and the content of bitter Amino Acid-phenylalanine in leg muscle was significantly lower than that in Hailan Brown Chicken P0.05. 3) the unsaturated fatty acid in the leg muscle of Hailan Brown Chicken was significantly lower than that in Hailan Brown Chicken.The contents of saturated fatty acids and total fatty acids were significantly lower than those of Hailan Brown Chicken, and the contents of arachidonic acid and 22 carbohexaenoic acid in the leg muscles of Hailan Brown Chicken were significantly higher than those in Hailan Brown Chicken (P0.05. 4).Significantly or extremely significantly higher than Hailan Brown Chicken,The contents of P0. 05, P0. 01) and P0. 05) in leg muscle were significantly higher than those in Hailan Brown Chicken.It can be seen that the muscle quality of Bashang long tail chicken and Hailan brown chicken is good, and the muscle quality of Bashang long tail chicken is better than that of Hailan brown chicken.
