Effect of gender on meat production and meat quality characteristics of Hu sheep
In order to explore the effect of gender on the meatquality characteristics of Hu sheep,seven August-aged Hu sheep were selected to determine their slaughter performance,eating quality of longissimus dorsi,muscle microstruc-ture and nutritional components.The results showed that the loin eye area of ram was significantly higher than that those of ewes,the shear force and cooking loss of ram longissimus dorsi were significantly higher than those of ewes.Gender had a great effect on the muscle microstructure of Hu sheep.Compared with ewe,ram's muscle fiber diameter was lar-ger,muscle tissue was tight and muscle skeleton protein was tightly folded.There were significant differences in the nu-tritional composition of Hu sheep meat between different genders.The contents of water,crude protein and erucic acid in longissimus dorsi of ram were significantly higher than that of the ewes,and the contents of crude fat were significantly lower than ewe,C20:3n6 was not detected in ewes.The contents of essential amino acid and umami amino acids in longis-simus dorsi of ewes were higher than those of rams.In general,the slaughter performanceand muscle fiber morphology of Hu sheep were better that those of ewes,the food quality,muscle fiber skeleton protein morphology and nutritional com-ponents were better than that of the rams.
