Blood profile of three-breed crossbred cows in estrus phase.

摘要

Between 1 December 1991 and 31 August 1992 at the Jawaharal Nehru Krishi Vishwa Vidyalaya livestock farm (Jabalpur, India) haematological characteristics of 121 Friesian X Jersey X Gir cattle during oestrus and non-oestrus phases were studied. The packed cell volume, percentage haemoglobin and total erythrocyte count were significantly higher and the erythrocyte sedimentation rate and total leucocyte count were significantly lower in the non-oestrus phase than in the oestrus phase. These effects were most marked when the symptoms of oestrus were most intense.
