Comparative Study on Muscle Nutritional Components between Bashang Long-Tail and Hy-Line Brown Chickens
摘要
Abstract
Bashang long-tail chicken is the only local poultry variety included in Animal Genetic Resources in China of Hebei province.In order to better protect and exploit the resources of Bashang long-tail chicken, one hundred and eighty 200-day-old Bashang long-tail chicken and Hy-Line brown chicken were selected and divided into 5 replicates randomly with 36 chickens per replicate.At 230 days of age, ten chickens of each breed were slaughtered and main nutrient components in the muscle were analyzed and compared under the same feeding and management conditions.The results showed as follows: 1) the contents of crude protein and crude fat in muscle of Bashang long-tail chicken and Hy-Line brown chinken had no significant difference (P>0.05).2) There was no significant difference in essential amino acid content between breast muscle and leg muscle of two breeds (P>0.05).The contents of delicious amino acids (glutamic acid, aspartic acid, glycine and alanine)in muscle of Bashang long-tail chicken were significantly higher than those of Hy-Line brown chicken (P<0.05), and bitter amino acid phenylalanine content in leg muscle of Bashang long-tail chicken was significantly lower than that of Hy-Line brown chicken (P<0.05).3) The contents of unsaturated fatty acids, saturated fatty acids and total fatty acids in leg muscle of Bashang long-tail chicken were significantly lower than those of Hy-Line brown chicken (P<0.05).The contents of arachidonic acid and aocosahexaenoic acid in leg muscle of Bashang long-tail chicken were significantly higher than those of Hy-Line brown chicken (P<0.05).4) The contents of magnesium (P<0.01) and iron (P<0.05) in breast muscle of Bashang long-tail chicken were significantly or extremely significantly higher than those of Hy-Line brown chicken, and the contents of sodium (P<0.05) , magnesium (P<0.01) and iron (P<0.05) in leg muscle of Bashang long-tail chicken were significantly or extremely significantly higher than those of Hy-Line brown chicken.In conclusion, muscle quality of Bashang long-tail and Hy-Line brown chickens is reasonable, moreover, the quality of Bashang long-tail chicken is better than that of Hy-Line brown chicken.关键词
