Determination and Comparative Analysis of Meat Quality of Breast Muscle and Leg Muscle of Zhijin White Goose of Different Sex
In order to study the effect of gender on the breast muscle and leg muscle quality of Zhijin white geese,40 healthy 10-week-old Zhijin white geese(25 male geese,15 female geese)with similar body weight were randomly selected for slaughter,and the color,pH value,shearing force and water loss rate of breast muscle and leg muscle were measured and analyzed.The moisture,crude protein,crude fat,amino acid,fatty acid,vitamin,iron,copper,zinc and other indexes of breast muscle were determined and analyzed.The results showed that the pH value and water loss rate of breast muscle and leg muscle of male and female geese were not significantly different(P>0.05),and the shearing force of leg muscle of male and female geese was significantly higher than breast muscle(P<0.01).The yellowness and redness of leg muscle of male geese were significantly higher than breast muscle(P<0.01),and the brightness of leg muscle was significantly higher than breast muscle(P<0.05).The yellowness of leg muscle of female geese was significantly higher than breast muscle(P<0.01).The content of vitamin A in breast muscle of male geese was significantly higher than female geese(P<0.05),the content of magnesium in breast muscle of female geese was significantly higher than male geese(P<0.01),but there was no significant difference in other indexes.In summary,gender has an effect on the muscle quality of breast muscle and leg muscle of 10-week-old Zhijin white goose.The breast muscle of male goose is rich in vitamin A and various fatty acids,while the breast muscle of female goose contains more mineral elements.
