The major objective of this study was to find out the consequence of exogenous administration of oxytocin to
Sahiwal cow, local breed of Pakistan (to enhance milk let down) on mineral composition. Milk samples were
collected from two groups of eight animals under controlled atmosphere and feeding input. The analysis of fodder
and feed samples were also carried out to support this study. Means of macro and micro minerals of fodder and
feed samples were determined. One group of Sahiwal cows was subjected to intramuscular injection of oxytocin
(20 IU). The milk obtained from oxytocin injected animals possessed significantly higher sodium and chloride with
increment in ash content. Lactose content decreased by 0.39% and ash content increased by 0.08% in milk
treated with oxytocin injections. Oxytocin administration increased the level of Na (19.74%), Cl (9.39%) and Cu
(146.89%) while K content decreased (10.06%).
