Abstract

The study was conducted on 85 neonatals of Pak-Karakul sheep at the Sheep and Goat Development Centre, Rakh Khairewala, District Layyah, Pakistan, with the aim of assessing the relationship of immunoglobulins to neonatal lamb mortality. Overall mortality in neonates was 8.24%. Surviving lambs (3.77±0.07 kg) were significantly (P<0.001) heavier than those that died during the neonatal period (2.79±0.018 kg). Males were significantly (P<0.05) heavier than females (3.84±0.11 vs. 3.52±0.09 kg). The lambs that survived the neonatal period had a significantly (P<0.001) higher level of immunoglobulins (30.89±0.87 ZST units) than those that died (7.08±1.99 ZST units). The mean total serum protein values for surviving and dead lambs, using a refractometer, were 78.51±1.86 and 47.14±4.84 g/l, respectively. The turbidity values below 10 ZST units and total serum protein level below 50 g/l may be considered as an indication of hypogammaglobulinemia and consequently an increased susceptibility to diseases and subsequent deaths.
