【摘要】：为探究奶牛静脉血、胎盘组织、脐静脉血和犊牛静脉血中脂联素之间及与犊牛初生重的相关性,选取规模化养殖场正常分娩奶牛54头,按犊牛初生重将奶牛分为3组:A组,≤40kg,9头;B组,40~45kg,25头;C组,≥45kg,20头。分别采集分娩奶牛颈静脉血、胎盘组织、脐静脉血及犊牛颈静脉血,ELISA法检测血液及胎盘组织脂联素水平,相关分析法分析各样品之间及与犊牛初生重的相关性。奶牛静脉血脂联素水平((29.15±4.02)mg/L)高于脐静脉血((13.79±1.14)mg/L)与犊牛静脉血((13.46±0.94)mg/L)脂联素水平,差异极显著(P0.01),脐静脉血脂联素水平高于犊牛静脉血脂联素水平,但差异性不显著(P0.05);奶牛静脉血脂联素水平与胎盘组织、脐静脉血、犊牛静脉血脂联素水平以及胎盘组织脂联素水平与脐静脉血、犊牛静脉血脂联素水平相关性均不显著(P0.05),脐静脉血脂联素水平与犊牛静脉血脂联素水平极显著正相关(P0.01);犊牛初生重与奶牛静脉血脂联素水平无显著相关性(P0.05),与脐静脉血、胎盘组织脂联素水平极显著正相关(P0.01),与犊牛静脉血脂联素水平显著正相关(P0.05);奶牛静脉血、胎盘组织、脐静脉血脂联素水平及犊牛静脉血脂联素水平在公、母犊间差异均不显著(P0.05)。脐静脉血、胎盘组织脂联素水平对犊牛初生重有非常显著的影响,犊牛静脉血脂联素水平对犊牛初生重具有一定影响,而奶牛静脉血脂联素水平对犊牛初生重的影响不显著;奶牛静脉血、脐静脉血、胎盘组织及犊牛静脉血脂联素水平在公、母犊间差异均不显著。
[Abstract]:In order to explore the correlation between bovine venous blood, placenta tissue, umbilical vein blood and calf venous blood adiponectin and the primary weight of calves, 54 cows were selected in a scale breeding farm, and the cows were divided into 3 groups according to the primary weight of calves: group A, less than 40kg, 9 heads, group B, 40~45kg, 25 heads, C group, more than 45kg, 20 heads. The jugular blood of dairy cows was collected, respectively. The level of adiponectin in blood and placenta tissue was detected by ELISA method in placental tissue, umbilical vein blood and calf jugular vein. Correlation analysis was used to analyze the correlation between the samples and the primary weight of calves. The level of serum adiponectin ((29.15 + 4.02) mg/L) was higher than that of umbilical vein blood ((13.79 + 1.14) mg/L) and calf vein blood ((13.46 + 0.94) mg/L). The level of serum adipin was very significant (P0.01), and the level of adipin in umbilical vein was higher than that of calf vein blood lipid, but the difference was not significant (P0.05). The level of adipin and placental tissue, umbilical vein blood, calf vein blood lipid level, placental tissue adiponectin level and umbilical vein blood, calf vein blood lipid level There was no significant correlation (P0.05). The level of adiponectin in the umbilical vein was significantly correlated with the level of blood lipid associated with calf vein (P0.01); there was no significant correlation between the primary weight of calves and the level of blood lipid associated with the cows (P0.05), which was positively correlated with the level of adiponectin in the umbilical vein and the placental tissue (P0.01), and the level of adiponectin in calf vein was significantly positive. Correlation (P0.05); blood, placenta tissue, umbilical vein blood lipid level and calf vein blood lipid level between male and female calves were not significant (P0.05). Umbilical vein blood, placental tissue adiponectin level has a very significant effect on newborn calf weight, calf vein blood lipid level has a certain effect on newborn calf weight. The effect of blood lipid level on newborn calves was not significant. The levels of blood, umbilical vein, placenta and calf vein were not significant between the male and the female calves.
