TI  - Changes in some blood constituents of Barki ewes during pregnancy and lactation 
      under semi arid conditions.
PG  - 269-277
AB  - A study based on 12 pregnant and six dry Barki ewes was carried out to examine 
      the changes in blood constituents during pregnancy and lactation periods. The 
      blood parameters were blood hemoglobin, packed cell volume percent (PCV%), mean 
      corpuscular hemoglobin concentration (MCHC), glucose, aspartate aminotransaminase 
      (AST or GOT), alanine aminotransaminase (ALT or GPT), total plasma protein, 
      albumin, globulin, albumin to globulin ratio (A/G), urea and creatinine. During 
      pregnancy all these parameters started to increase significantly, but in 
      different stages, reaching maximum values at parturition. In contrast, dry ewes 
      showed almost stable values during the experimental period. From 10th week to 
      parturition, PCV% and MCHC increased (P<0.01) in pregnant ewes, which resulted in 
      increased (P<0.01) blood hemoglobin. Blood glucose increased from the 4th week of 
      pregnancy to reach its maximum at parturition (60.15-90.08mg/dl). The two 
      transaminases increased significantly from the 2nd week (52.23-65.02IU for AST 
      and 8.02-15.12IU for ALT). Plasma protein with its two components, albumin and 
      globulin, increased significantly at the 6th week, but dropped throughout the 
      16-18th week of pregnancy. Urea and creatinine began to increase significantly 
      after 10-12 weeks of pregnancy (from 54.73 to 72.11mg/dl for urea and from 0.882 
      to 2.475mg/dl for creatinine). During the first month of lactation, PCV decreased 
      sharply in lactating ewes and was significantly lower than in dry ewes at the 3rd 
      week of lactation (24.25 versus 27.17%), which resulted in a drop in blood 
      hemoglobin at the 4th week (68.42 versus 74.00g/l). However, lactating ewes 
      maintained significantly higher values of MCHC (30.01-31.19% for lactating versus 
      29.87-27.48% for dry). In lactating ewes, levels of glucose, ALT, urea and 
      creatinine returned to levels comparable to those in dry ewes. The same occurred 
      with total plasma proteins, mainly due to a sharp decrease in globulin, while 
      albumin remained higher than in dry ewes with a slow decline, which resulted in 
      higher values of A/G ratio during lactation. Aspartate aminotransferase remained 
      higher than in dry ewes.
