| 1 | 加钼或未加钼的低铜日粮对牛的铜状态、生产性能和胴体品质的长期影响显示文摘用42头7月龄安格斯公牛进行试验,测定加钼或未加钼的低铜饲粮对牛的生产性能、胴体品质和铜状态的长期影响。断奶前28d给22头犊牛注射90mg铜,断奶后,饲粮中添加铜7.5mg/kg干物质,对照组不添加铜。在获得铜后第40d末,铜的添加量降低到5mg/kg干物质,施铜期后,每组1/2牛的日粮中添加钼5mg/kg干物质。生长期持续196d随后为49d的肥育期,饲喂高浓度饲粮。试验结果表明:注射铜提高了断奶时牛的血浆铜浓度(P<0.01)。从生长期开始补加铜的牛具有较高的血浆铜含量、血浆铜蓝蛋白活性、过氧化物歧化酶(SOD)活性和肝脏铜浓度(P<0.01)。补加钼降低了未添加铜组牛生长期和肥育期血浆铜含量、血浆铜蓝蛋白和过氧化物岐化酶活性,但对加铜组的牛无影响。添加铜提高了施铜期(P<0.05)和生长期(P<0.08)牛的干物质采食量(DMI)及肥育期牛的日增重量(ADG)和饲料转化效率(G/F)。补加铜的牛的背膘厚度较薄(P<0.06),肋部眼肌面积较大(P<0.09)。研究结果证明,饲粮铜浓度可能改变牛的生产性能和胴体品质。 | Ward J D Spears J W 郭艳丽 | 1999 | 国外畜牧学(草原与牧草)1999，0，3： | 3 |
