In order to develop product and improve breeding for Guangxi partridge chickens,the slaughter performance,amino acids,inosine acid and fatty acids contents in muscle were measured and evaluated for Guangxi partridge chickens at 120 days old,which were raised at same nutrition level and management. Carcass traits and meat characteristics were evaluated. The results were showed that the dressing percentage and eviscerated yield percentage of cocks and hens were 90.15%,92.57% and 69.12%, 68.08%,respectively. The total amino acids in the breast and leg muscles of cocks and hens were 20.37,18.40 and 21.30, 18.44 g/100 g,respectively. The ratio of essential amino acids to total amino acids in breast and leg muscles of cocks and hens were 39.32%,42.33% and 42.72%, 43.06%,respectively,and essential amino acid index (EAAI) were 84.33,88.82 and 90.44, 90.77,respectively. The content of delicious,sweet,branched chain amino acids and inosinic acid in breast muscle were 0.85 g/100 g,0.42 g/100 g,0.56 g/100 g and 1.55 mg/g higher than that in leg muscle,respectively,and the content of sweet amino acids in hens was 0.40 g/100 g more than that in cocks. The first limiting amino acid was Met+Cys in muscle of Guangxi partridge chickens. Oleic acid and linoleic acid were mainly components of unsaturated fatty acids in muscle,palmitic acid and stearic acid were mainly components of saturated fatty acids in muscle. The relative content of polyunsaturated fatty acids and essential fatty acids in leg muscle were higher than that in breast muscle, and their contents in hens were more than that in cocks. All these showed that the Guangxi partridge chickens had good meat production,flavor and high nutrition value,meanwhile the nutritional values in hens were superior than that in cocks. 相似文献

In order to measure the nutritional characteristics of Black-White rabbit meat,the nutrient components,the conventional nutrient,amino acid and fatty acid content of leg muscle in Black-White rabbit were tested and analyzed,and the protein nutritional values were evaluated based on the National Food Security Standard and chemical analytical method of product quality. The results showed that the moisture,crude proteins,crude fats and ash in leg muscle of Black-White rabbit were 73.43%,21.67%,3.83% and 1.13%,respectively. There was no significant difference on the nutrient components between female and male rabbits (P>0.05). The total amino acids,essential amino acids and delicious amino acids were 196.53,78.64 and 70.80 mg/g,respectively. According to amino acid score (AAS),the first limiting amino acid of Black-White rabbit was Val and the second limiting amino acid was Met+Cys. However,based on the standard of chemical score (CS),the first limiting amino acid was Met+Cys and the second was Val. Additionally,the ratio of unsaturated fatty acids (UFA) to saturated fatty acids (SFA) was 1.74,and no significant difference was found on the amino acids between female and male rabbits (P>0.05). More specifically,except the fatty acid of C16:1 and C18:3, there was no significant difference in the fatty acid compositions between female and male rabbits (P>0.05). In conclusion,Black-White rabbit meat was composed of high proteins,delicious amino acids and essential amino acids suggesting that it had better balance of amino acids. The unsaturated fatty acids in Black-White rabbit meat were higher than saturated ones meaning high nutritional value and better dietary values. 相似文献
