【摘要】 性别是影响动物生长发育和肉品质的一个重要的因素,此试验研究目的在于明确是否性别对秦川牛肉品质存在显著影响选取发育正常、健康无病、年龄在3岁左右的秦川牛公牛3头、母牛3头、阉牛3头共9头牛进行屠宰试验,并在同一部位(背最长肌处)进行取样测定水分、粗灰分、粗脂肪、粗蛋白、肉色、蒸煮损失、失水率、嫩度和系水力9项指标。结果如下:秦川牛的性别对背最长肌处的水分,粗灰分和肉色的影响不显著(P>0.05),而其余指标在不同性别之间则有显著或极显著的差异(P<0.05或P<0.01)。综合几个指标可以得出:秦川牛阉牛肉质优于母牛,公牛最差。但是否需要进行阉割,在生产实际中还要根据饲养的品种,肥育期和饲养条件来决定。更多还原

【Abstract】 Gender is one of the most important factors on growth and meat quality. The purpose of this paper is to make clear the effect of gender on Qinchuan Cattle. Nine healthy Qinchuan cattles (three ones separately by gender, about three years old) were slaughtered to study the influence of gender on meat quality. Sampling at longissimus dorsi and the following items were measured, including content of water, crude ash, crude fat, crude protein, meat colour, cooking loss, tenderness, driage and water holding capacity. Results are shown as follows: content of water, crude ash and meat colour are not influenced significantly by gende(r P>0.05). Other items are different or significantly different among gender(P<0.05 or P<0.01).Comprehensive analysis shows that meat quality of bull is the best and ox is the worst of all. However, whether the cattle shoud be castrated or not will be determined by the species you intend to breed, the stage of fattening and the breeding condition.更多还原
