Effect the stages of lactation on some hematological and biochemical parameters in ewes

Abstract

This study was conducted on the sheep of the Animal House/Tikrit university/College of Veterinary Medicine In period between 15.12.2009 to 30.1..2020, The total animal was used is 15 ewes  . Five ml  of  blood  samples were collected from the jugular vein in the different stages of the lactation , as the study include 15 ^th , 30 ^th and 45 ^th  day of lactation. Where used for determine hematological and biochemical parameters.

The results   revealed A decreased (P ≤0.05) in total red blood cells, haemoglobin and packed cell volume,  (4.6 ±1.03,  7.7 ±0.25, 23.1±1.56) respectively in  15 day of the lactation compare with 30th and 45 day of the lactation. The total white  blood  cells  count were  decreased (6.8 ±0.41)  during  the 45 day of the lactation. Results  demonstrate  significant  decrease (P ≤0.05)  in  concentration  total of protein, glucose, cholesterol ,triglyceride  and urea concentration (6.8±0.18, 66.3 ±0.44, 52±0.78, 36.8±0.05, 28 ±0.45) respectively at  the  15 day  of  lactation. While creatinine decreased (P ≤0.05) during the 45th day of the lactation (0.86±6.65). we conclude,  from the study that there are present differences significant in hematological and biochemical parameters during the first stages of lactation.
