茴香副产物对湖羊生长性能、屠宰性能和肉品质的影响
Effects of fennel by-products on growth performance,slaughter performance,and meat quality of Hu sheep
摘要
Abstract
The experiment aimed to investigate the effects of three fennel by-products,namely fennel residue,fennel straw,and fennel husk on the growth performance,slaughter performance,and meat quality of Hu sheep.A total of 80 aged two months weaned male Hu lambs with a body weight of(19.24±1.94)kg were selected and randomly divided into four groups,with four replicates per group and five lambs per replicate.The control group was fed a basal diet,while the experimental groups were fed diets in which barley straw in the basal diet was completely replaced by fennel residue,fennel straw,or fennel husk,respectively.The pre-test period lasted for seven days,and the formal test period lasted for 90 days.The results showed that the final body weight,total weight gain,and average daily gain in the fennel residue group were significantly higher than those of the other groups(P<0.05),and the feed-to-gain ratio was significantly lower than that of the control group and the fennel straw group(P<0.05).The fennel residue group exhibited the highest dressing percentage and net meat percentage,but no significant differences were observed among the groups(P>0.05).The loin eye area in the fennel residue group was significantly higher than that of the other groups(P<0.05),and the GR value was significantly lower than that of the control group(P<0.05).The fennel residue group showed the lowest muscle lightness(L*)value,water loss rate,and shear force,which were significantly lower than those of the control group and the fennel straw group(P<0.05),and its drip loss was significantly lower than that of the control group(P<0.05).The fennel residue group had the highest essential amino acid content and umami amino acid content,which were significantly higher than those of the control group and the fennel straw group(P<0.05).The study shows that replacing barley straw with fennel residue in the diet can improve the growth performance,slaughter performance,and meat quality of Hu sheep.关键词
