Abstract
The objective of this study was to investigate the correlation between the plasma progesterone and some chemical milk constituents (fat%, lactose% and chlorine % ) during the different phases of estrous cycle and early pregnancy in buffaloes. Thirteen buffaloes aged 4-8 years were included in this study, 5 animals were used to study the correlation between milk progesterone and some chemical milk constituents during estrous cycle which was induced by using Cloprostenol (Estrumate-ICI). Another 8 animals with known date of mating were used to study the same correlation during the early pregnancy. Blood and milk samples were collected for plasma Progesterone assay and determination of some chemical milk constituents (fat%, Iactose7% and chlorine%)., A strong negative correlation was observed between Plasma progesterone and lactose % during estrous cycle and early pregnancy(r =-0.84 + 0.02 and r = -0.87 + 0.03, respectively,). Meanwhile, a strong positive correlation was observed between plasma progesterone and chlorine% during estrous cycle and early pregnancy (r = 0.87+0.03 and r = 0.93 + 0.02, respectively). On the other hand, no significant correlation was observed between milk progesterone and fat%. This study concluded that measuring of milk lactose and or chlorine could be of value in monitoring the ovarian cyclicity and early pregnancy diagnosis in buffaloes.
