摘要/Abstract

摘要： 本试验旨在研究日粮中添加不同水平莫能菌素对泌乳期奶牛生产性能和养分消化率的影响。选取泌乳期荷斯坦奶牛12头,采用重复4×4拉丁方试验设计,随机分成4组,每组3个重复,对照组饲喂基础日粮(A组),试验组分别在基础日粮的基础上添加300 (B组)、400 (C组)、500 (D组)mg/(头·d)莫能菌素。试验分为4期,每期28 d (7 d预饲期,21 d正饲期)。结果表明,日粮中添加莫能菌素可以提高泌乳期奶牛产奶量和乳糖率,降低乳脂率,其中C组和D组的平均日产奶量分别较对照组提高4.08%和4.57%(P < 0.05),D组的乳糖率较对照组提高1.99% (P < 0.05),D组的乳脂率较对照组降低7.45% (P < 0.05),但对4%乳脂校正乳(FCM)、乳中非脂固型物(SNF)比例和乳蛋白率的影响不显著(P > 0.05)。莫能菌素会提高奶牛的体增重(BWG)及粗蛋白质(CP)、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)的表观消化率,其中D组的BWG较对照组提高34.62% (P < 0.05),3个试验组的CP消化率分别较对照组提高3.73%、4.35%和5.35% (P < 0.01),D组的NDF和ADF消化率分别较对照组提高7.24%和9.08% (P < 0.05),另外,莫能菌素对泌乳期奶牛的粗脂肪(EE)、钙(Ca)和磷(P)的消化率及干物质采食量(DMI)影响不显著(P > 0.05)。综上所述,在泌乳期奶牛日粮中添加莫能菌素可以促进奶牛机体代谢,提高奶牛养分消化率和经济效益,其适宜添加量为400~500 mg/(头·d)。

Abstract: Twelve lactating Holstein dairy cows were selected via a replicated 4 × 4 latin square design to determine the effect of feeding different levels of monensin on the production performance and nutrient digestion of lactating dairy cows.The test was divided into 4 period and each period was 28 d (7 d for preliminary feeding and 21 d for formal feeding).The cows in control group were fed with the basal diet (TMR,group A),and the diets of the three experimental groups were added with different levels of monensin (300 mg/d,group B;400 mg/d,group C;500 mg/d,group D) on the basis of the TMR diet,respectively.The results showed that the diets containing monensin increased the milk yield and lactose percentage,and reduced milk fat percentage.Compared with control group,the milk yield of group C and D were significantly increased by 4.08% and 4.57% (P < 0.05) respectively,the lactose of group D was significantly increased by 1.99% (P < 0.05),and milk fat of group D was significantly reduced by 7.45% (P < 0.05).However,adding monensin had no effect on 4% fat corrected milk (FCM),solids-non-fat (SNF) and milk protein (P > 0.05).In addition,adding monensin also significantly increased body weight gain (BWG),digestibility of crude protein (CP),neutral detergent fiber (NDF) and acid detergent fiber (ADF) in diet.The BWG of group D was significantly increased by 34.62% (P < 0.05),and the digestibility of CP in three experimental groups were respectively increased by 3.73%,4.35%,5.35% (P < 0.01),and the digestibility of NDF and ADF in group D was respectively increased by 7.24% (P < 0.05)and 9.08% (P < 0.05) compared to the control group.Moreover,the dry matter intake (DMI) and the digestibility of ether extract (EE),calcium (Ca) and phosphorus (P) were not significantly changed by monension (P > 0.05).The results suggested that supplementing 400 to 500 mg/d monensin with diet per cow was optimal for production performance,nutrient digestion and economic benefit of lactating dairy cows.
