Relationship of corpus luteum size with progesterone level in mammalian milk

ABSTRACT

Relationship corpus Luteum [CL] size with milk progesterone level in Nili-Ravi buffalos was studied. One hundred lactating bufaloes were randomly selected. Milk progesterone level was determined with the help of enzyme immunoassay technique and post-slaughter examination of corpus huteum was used as a criterion for confirmation-of EIA diagnosis of CL and its comparison with concurrent milk progesterone level. Single CLs had fairly good relationship with concurrent milk progesterone level [correlaton co-efficient 0.928 and covariance 23.77] but double CLs did not have any significantt relationship with the milk progesterone level [correlation co-efficient 0.375 and covariance 4.99]
