Abstract
The study conducted on 525 ewes revealed
significant (P<0.05) increase in TLC at post-lambing than pre lainhing
stage. Serum globulins and total protein increased significantly (P<0.05)
after parturition, while other parameters including RBC, PCV, Hh conc.,
serum immunoglobulins (ZST-units) and albumin showed relative increase at
post than pre-lambing stage. Serum concentration of globulins at post
lambing were significantly higher (P<0.05) in ewes given birth to male
neonates with non-significant difference in other parameters. Concentration
of colostral iinmnunoglobulins was low (P<0.05) in dams whose lambs died
within a week of parturition tli those whose lambs survived, however, other
parameters including serum immunoglohulins, serum total proteins. Albumin
and globulins showed non-significant diffi between darns whose lambs
survived or died. The RBC counts were significantly (P<0.05) lower at post
lambing in ewes given birth to neonates weighing 4 Kg arid above than
weighing 2-3 Kg. Serum immunoglobulins at pre-lambing were significantly
(P<0.05) higher in ewes at their parity than ewes at their 41 parity.
Colostral immunoglobulins showed no correlation with senun iminunoglobulins
both at pre and post-lambing stage, while globulins were significantly
(P<0.05) correlated with serum iimnunoglobulins at pre-lambing (r = 0.21).
TLC showed significant (P<0.0l) inverse correlation with serum
iminunoglobullns at pre-lambing (r = -0.29) stage.
