Abstract
This
study was escorted to know the effect of
oxytocin administration before milking on milk production, somatic cells
count and fat contents in milk of buffaloes. Twenty lactating Nili-Ravi
buffaloes were randomly divided into two groups. Group A (n = 10) buffaloes were
treated intramuscularly with 30 IU of oxytocin daily before the start of milking
for the period of 7 days, whereas group B (n = 10) buffaloes were given no
treatment and served as control. Milk samples were collected from all buffaloes
7 days before (Phase I), during (Phase II) and after (Phase III) the treatment.
There were significantly higher (P<0.05) milk production (liters) during
phase-II in group A (8.57±0.07 liters) buffaloes as compare to group B
(8.40±0.04 liters) whereas non-significant differences were recorded in the mean
milk production between group A and B during phase-I (8.46 vs 8.43 liters) and
III (8.54 liters). Somatic cells count varied from 72.96 to 97.01 × 103
and 71.86 to 77.14 × 103 cells per ml in group A and B,
respectively. Mean somatic cells count were significantly higher (P<0.05) in
group A as compared to group B during phases II of study. During phase I, II and
III, there were non-significant differences (P>0.05) in fat percentage between
two groups of buffaloes. It was concluded that milk production and somatic cells
count in milk of Nili-Ravi buffalo were affected by oxytocin injection before
milking whereas there was no effect of oxytocin on milk fat percentage.
