甜菜粕替代玉米对奶牛生产性能及血液代谢的影响
Effects of Sugar Beet Pulp Substituted for Ground Corn on the Performance and Blood Metabolite of Dairy Cows
摘要
Abstract
The objective of this study was to evaluate the effect of sugar beet pulp (SBP) substituted for ground corn on the performance and nutritional status as measured using blood metabolites as an energy source feed-stuff for Chinese Holstein lactating dairy cows.Sixty multifarious Holstein cows(61 ± 21.6 DIM, 31.2 kg/d± 6.2 kg/d) were randomly divided into two pens and within each pen where three groups (control, 20SBP or 40SBP) and each group comprised of 10 cows (n= 10).Besides SBP and corn, The remainder of the ration was the same for all groups.The results showed that dry matter intake, milk production,energy corrected milk (ECM) were not effected by increasing SBP substitution(P＞0.05).The content and yields of milk protein, milk fat, milk lactose, total solids (TS) and solid non-fat (SNF) were unaffected by substituting SBP for ground corn (P＞0.05).As the SBP level increased, the content of milk composition was a rising tendency.In blood metabolite, the concentrations of blood urea nitrogen (BUN) and serum glucose decreased when SBP was added(P＜0.01 ).No significant difference in NEFA, BHBA, TG, LDLD, HDLD, TP, ALB, GLB, CHOL of the blood among the treatment groups in this experiment was detected.The results indicated that the performance and blood metabolite were unaffected by substituting SBP for ground corn, sugar beet pulp was equal to corn as an energy source, and decreased the cost.关键词
