纯种湖羊及其不同杂交组合F1代生长性能、产肉性能及肌肉品质比较分析
Comparative analysis of growth and meat production performance and muscle quality of F1 and pure Hu sheep
摘要
Abstract
To explore the differences in the growth and meat production performances and meat quality of different hybrid combinations.The study included 12 male lambs of Hu sheep(♂ Hu sheep×♀ Hu sheep,HH),AH F1(♂ Australian White sheep×♀ Hu Sheep,AH),NH F1(♂ Southdown sheep×♀ Hu sheep,NH),and TH F1(♂ Poll Dorset sheep×♀ Hu sheep,TH)aged 2 months old.A feeding test was started with the pre-feeding period of 10 days and a forward trial period of 60 days.After feeding,6 randomly selected animals were used for slaughter to determine slaughter performance and muscle quality.1)The average daily weight gains of NH F1 and TH F1 were significantly higher than those of Hu sheep(P<0.05).2)The live weights of AH F1 and NH F1 were significantly higher than those of Hu sheep(P<0.05).3)The marbling scores of AH F1,NH F1,and TH F1 were also significantly higher than those of Hu sheep(P<0.05).While the muscle shear force,cooked meat yield,cooking loss,brightness L*,and yellow degree b* were higher than those of Hu sheep,the differences were not significant(P>0.05).4)The crude fat content in AH F1 was significantly higher than that in Hu sheep,and the crude fat and dry matter contents in NH F1 were significantly higher than those in Hu sheep(P<0.05).5)The total and sweet amino acid content in the NH F1 were 15.76％and 17.83％,respectively,and they were higher than those of the F1 generation of purebred Hu sheep(P<0.05),respectively,while the content of umami amino acids in the NH F1 was significantly higher than that of the TH F1(P<0.05).The contents of serine,alanine,aspartic acid,and glutamic acid were also higher than those in the AH F1 and purebred Hu sheep(P<0.05),and that of histidine in the TH F1 was significantly higher than that of purebred Hu sheep(P<0.05).6)Among the saturated fatty acids,the contents of caproic acid,arachidic acid,and lignowaxic acid in the AH F1,NH F1,and TH F1 were significantly lower than those in Hu sheep,while that of capric acid was significantly higher(P<0.05).The monounsaturated fatty acid content in the NH F1 and TH F1 generations increased by 17.54％and 11.65％,respectively,relative to that of Hu sheep(P<0.05).The total content of polyunsaturated fatty acids in the TH F1 was 5.60％higher than that in Hu sheep(P>0.05).The amount of F1 reflux acid in TH and AH was significantly higher than that in Hu sheep(P<0.05).The total content of polyunsaturated fatty acids in the NH F1 was significantly lower than that in Hu sheep(P<0.05).In summary,the growth rate of offspring can be increased through crossbreeding,and meat production performance and meat quality can be improved.Comparatively,the NH F1 generation and the TH F1 generation have better results.关键词
