不同性别与体重水平三穗鸭的胸肌肉品质和脂肪酸含量
Meat Quality and Fatty Acid Content in Breast Muscle of Sansui Ducks with Different Gender and Body Weight Level
摘要
Abstract
[Objective]The growth performance,slaughter performance,meat quality and breast muscle fatty acid content of Sansui duck were investigated to provide a theoretical support for breeding,lipid nutritional metabolism regulation and industrial development of Sansui duck.[Method]65 Sansui ducks(21 males and 44 females)selected from 655 experimental ducks based on the physical and phenotypic characteristics were divided into SG group(high-body-weight group,n=35)and SD group(low-body-weight group,n=30).The growth and slaughter performance of two groups were investigated,and their breast muscle fatty acid content was determined by GS-MS targeted metabolomics technology to identify the fatty acids with significant differences between two groups.[Result]The pre-slaughter live weight,carcass weight,breast muscle ratio and subcutaneous fat ratio of SG group were significantly higher than those of SD group.Among 7 short-chain fatty acids in breast muscle of Sanshui duck,acetic acid had the highest content(38.09-40.12 μg/g),followed by butyric acid,propionic acid and caproic acid,and total content of four acids accounted for more than 95%of total short-chain fatty acids.A total of 51 medium and long-chain fatty acids were detected in breast muscle of Sansui duck.Among them,five most abundant fatty acids were oleic acid,palmitic acid,linoleic acid,stearic acid and arachidonic acid,respectively.15 fatty acids with significant differences in breast muscle of Sansui ducks with different body weight levels were screened out by an orthogonal partial least squares discriminant analysis(OPLS-DA).11 and 4 medium and long-chain fatty acids in SG group increased and decreased compared with SD group,respectively.The saturated fatty acids and monounsaturated fatty acids in breast muscles of SG group were higher than those in SD group.However,the ratio of ω-3 fatty acids and polyunsaturated fatty acids to saturated fatty acids,etc.showed no significant differences between two groups.[Conclusion]The meat quality of Sansui duck is excellent.The fatty acid deposition ability of Sansui duck in SG group is higher than that of Sansui duck in SD group.The fat acids in breast muscle may have a positive effect on growth and development of Sansui duck.关键词
