Studies on cisternal and alveolar fractions & its composition and mammary health of Murrah buffaloes administered oxytocin.
The study was conducted on 18 lactating Murrah buffaloes in 83.72 +/- 14.75 days after calving. Group I buffaloes were not injected with oxytocin and served as control. Buffaloes of Group II were injected with oxytocin @ 2.5 IU per 0.5 ml intramuscularly at the hip region for a period of 1 month while Group III buffaloes received injection of oxytocin @ 5.0 IU per ml intramuscularly at the hip region for a period of 1 month. Milk samples from three groups of buffaloes were collected after oxytocin injections at 15 days interval on 0, 15, 30 and 45 days. Blood samples were collected in heparinized tubes at 0, 15, 30 and 45 days of experiment from all three groups of buffaloes. There was no significant change in cisternal, alveolar and total milk yield by exogenous oxytocin administration. Fat % in cisternal, alveolar and total milk decreased significantly (P < 0.01) by 11.8% and 21.3% in groups II and III buffaloes, respectively. Protein % increased significantly (P < 0.01) in group III. A significant increase was observed in somatic cell counts of milk by 5.36% and 6.22% in groups II and III, respectively as compared to control group.
