Plasma B-endorphin in buffaloes and cows with and without retained placenta

ABSTRACT

This study was conducted on 14 and 12 pluriparous buffaloes and cows respectively, seven of the buffaloes and six of the cows had retained placenta. Blood samples were collected from all animals in heparinized vacutainer tubes and cooled on ice, plasma was removed by centrifugation in a cooling centrifuge and freezed at -20 until assayed for B-endorpfcin. Statistical analysis revealed significantly [P < 0.02] higher plasma levels of B-endorphin in both buffaloes [1045.417 +/- 148.156 Pg/ml] and cows. [969.666 +/- 140.064 Pg/ml] with retained placenta than in buffaloes [74.246 +/- 8.772] and cows [95.00 +/- 12.02l] without retained placenta. It is suggested that, B-endorphin would be considered as a factor which probably influences the retention of placenta in farm animals
