Abstract:
It is essential to understand underlying metabolic stress influencing uterine inflammatory conditions. Therefore, the present study was undertaken to assess the metabolic stress influencing endometritis in crossbred dairy cows reared in the central dry zone of Karnataka. The cows considered for the present study were divided into four groups viz., Group- I (Control N=8): crossbred cows at 3 weeks to 11 weeks of postpartum estrus with negative White side test (WST), Group- II (N=8): crossbred cows at 3 weeks to 5 weeks of postpartum estrus, Group- III (N=8): crossbred cows at 6 weeks to 8 weeks of postpartum estrus, Group- IV (N=8): crossbred cows at 8 weeks to 11 weeks of postpartum estrus. Group II to Group IV with positive WST and designated as clinical endometritis cases (CE). Metabolic profile included estimation of Non-esterified free fatty acids (NEFA), beta hydroxy butyric acid (BHBA), blood glucose, total protein, albumin, total cholesterol, total bilirubin, blood urea nitrogen (BUN), creatinine, aspartate amino transferase (AST), Alanine amino transferase (ALT) and mineral profile included estimation of calcium and phosphorous. Statistical analysis of data revealed a significant difference (p<0.05) between concentrations of BHBA and NEFA in groups of II, III, IV when compared to group-I. There is no significant difference (p<0.05) found in blood glucose and plasma total proteins levels in all groups compared to control group. Concentrations of BUN and the cholesterol in groups II, III, IV significantly higher compared to group-I. However, the mean values of creatinine were within the normal threshold range in all groups. There was a significant (p<0.05) difference between total bilirubin concentrations in group-II compared to control group. However, group-III and group-IV were comparable with control group. There were no significant findings with respect to ALT and AST enzymes. There is a significant (p<0.05) difference in the concentrations of calcium and phosphorous of all the groups compared with control group. The present revealed that the associations of elevated NEFA, BHBA, lower levels of calcium and phosphorous may affect the uterine health and estimation of such biochemical parameters are helpful in monitoring udder health in dairy cows.
