Fluctuation of some blood parameters throughout the estrous cycle in goats

ABSTRACT

Seven healthy mature Baladi does [10-14 months old] were used in the present study. Estrus was synchronized using lutalyse. Heat was detected by the use of rutting aproned buck. Individual blood samples were collected daily in the morning throughout the two successive cycles following the 1st post-synchronized cycle. Each sample was divided into three portions for determination of ERS, hematological studies as well as for serum separation for biochemical analysis. The results revealed that RBCs count and Hb concentration as well as total leucocytic count and neutrophils% were significantly higher during estrous phase, whereas, ESR and platelets count as well as lymphocyte% were significantly lower during that phase. Urea, creatinine and ACP levels were significantly low during estrous phase, whereas, ALP, AST, total bilirubin uric acid, total proteins, albumins, globulins, total calcium, inorganic phosphorus, total glucose levels were significantly higher during that phase
