摘  要：
选择8头健康产奶水牛, 按产犊时间、胎次及产奶量相近的原则随机分成4组。采用4×4拉丁方设计, 试验分4期, 4个日粮处理组分别为对照组、半胱胺(CS) 处理组(10mg/d·kg体重)、有机铬(CrP) 处理组(0 8mg/kg精料) 及蛋氨酸羟基类似物(MHA) 处理组(35g/d·头), 研究CS、CrP和MHA对水牛产奶量、乳成分及血液生理生化指标的影响。试验结果表明: (1 ) CS、CrP和MHA组的产奶量分别比对照组提高3 89%、6 80%、5 90%, 但统计上差异不显著(P>0 05)。(2) CS和CrP组的乳总干物质比对照组稍低, 但MHA组的乳总干物质比对照组提高了2 25% (P>0 05); CS组乳中乳蛋白比对照组稍低, 而CrP和MHA组乳中乳蛋白分别比对照组提高1 29%和1 55% (P>0 05 );CS和CrP组乳中乳脂率分别下降4 08%和3 55% (P>0 05); 而MHA组乳脂率提高了8 17% (P>0 05)。(3) CS、CrP和MHA组血清总蛋白分别比对照组下降2 80%、11 22%和0 82% (P>0 05); CS和CrP组血清甘油三酯分别提高16 67%和11 11% (P>0 05 ); 三个处理组血清中无机离子(钾、钠、氯、钙、磷) 的含量与对照组无显著差异(P>0 05 )。(4 ) CS、CrP和MHA对血清谷丙转氨酶(ALT)、碱性磷酸酶(ALP)、乳酸脱氢酶(LDH) 活性无显著影响(P>0 05); MHA组血清胰岛素(INS) 显著提高22 33% (P<0 05),

摘  要：
Eight healthy lactating buffaloes were selected and used in a 4×4 latin square trial with four periods and four treatments. Cysteamine (CS) (10mg /kg·BW), Chromium Picolinate (CrP) (0.8mg CrP /kg concentrate.) and methionine hydroxy analogue (MHA) (35g /d·buffalo) were respectively supplemented to basal diet (the control group) in order to study the effects of CS, CrP and MHA on lactating performance and serum physio-biochemical indices of lactating buffalo. The results showed: (1) compared with control group, CS, CrP and MHA increased milk yield by 3.89%, 6.80% and 5.90%, respectively (P>0.05). (2) MHA increased total milk solid by 2.25% (P>0.05); CrP and MHA increased milk protein by 1.29% and 1.55% respectively (P>0.05); MHA increased milk fat by 8.17% (P>0.05); CS and CrP decreased by 4.08% and 3.55% respectively (P>0.05). (3) The effects of CS, CrP and MHA on serum physio-biochemical indices were not significant (P>0.05); CS, CrP and MHA decreased serum total protein by 2.8%, 11.22% and 0.82% respectively (P>0.05); CS and CrP increased serum triglycerides by 16.67% and 11.11% respectively (P>0.05); The concentrations of serum inorganic ions (K, Na, Cl, Ca, P) had no significant differences among treatments. (4) The effects of CS, CrP or MHA on alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were not significant (P>0.05); The concentration of serum insulin (INS) in MHA group increased by 22.33% (P<0.05); prolactin (PRL) and free triiodothyronine (FT 3) increased by 15.38% and 1.61% respectively (P>0.05); The effects of CS and CrP on serum PRL, FT 3 or INS were not significant (P>0.05).
