Physiological response of subclinicaly ketotic buffaloes to some exogenous treatments
|
|
Abstract: Two preliminary consecutive surveys were implemented using the nitroprussed test in winter and summer to reveal incidence rate of ketosis among Egyptian buffaloes Results of the survey showed no positive reading from the milk sample in winter or summer. Only 10% of the urine samples exhibited a positive results in dry buffaloes (39.8%) but not in lactating ones. A number of 25 subclinically dry ketotic buffaloes were un equally distributed among 5 groups and treated during pre and post – partum periods with niacin (N,12g/ head/day ), niacin plus molasses (N,6g+M,150ml/head/day), dexamethazone (D,40mg/head/wk), high energy grain corn silage (S,15kg/head/day), subclinically ketotic buffaloes as non – treated group (C) in addition to healthy group (H, non-ketotic). Estimates of milk production, milk fat %, milk protein %, blood metabolic profile and reproductive efficiency parmeters were recorded for the experimental groups
Daily milk yield was reduced in group C of buffaloes in comparison with that of the healthy group (5.91 vs. 8.80 kg /day ). There were no significant differences in milk production or its composition of fat and protein between the studied groups. Average milk yield /day was the highest in groups S, D and N and it was comparable with productivity of the healthy group. Milk fat % was the highest in the healthy group and group S whereas milk protein % was greater in groups D, N and S.
Post – partun differences between groups in plasma total lipids, calcium and thyroid hormones concentrations as well as hepatic enzyme activity were significant. On the other hand, no significant differences were detected in concentrations of blood proteins, glucose, cholesterol and blood urea nitrogen between the experimental groups. Group S maintained significantly its blood content of glucose, calcium, phosphorus and thyroid hormones at post- partum period. Plasma content of cholesterol was higher in the healthy group at the post-partum period than the treated groups (P<0.05).Generally, group H of buffaloes showed no difference than group C in reproductive perameters. Silage feeding relatively reduced the number of services/conception, service period and consequently calving interval in comparison with the healthy or treated groups. Conclusively, using high enargy diets such as corn silage and or niacin treatment at late pregnancy period is recommended to prevent and overcome the expected metabolic disorders.
