While it is not possible to save every single lamb, but there is huge scope to reduce mortality percentage for economic sheep production through development of sheep flock health programs. These flock health programs require information on diseases and their predisposing factors causing mortality and thus huge economic losses. Therefore, this information pertaining to losses through deaths need to be in form of profile indicating importance of disease and predisposing factors in terms of susceptible age group, seasonal incidence of the disease and the annual variation in its occurrence. Hence an investigation of overall mortality to identify predisposing factors at Sheep Breeding Farm, Kralpathri was carried out from 2013 to 2020 with accurate data recording for lambing and mortality. Total of 7733 animals were studied. Among them 2385 male and 5348 females were studied. Overall mortality recorded was 823 (10.64%). Among them were 387 (16.23%) males and 436 (8.15%) females. High mortality was observed upto 1 year age i.e. 592 (29.39) than after 1 year age i.e. 231 (4.03). Majority of deaths occurred due to infectious diseases (625, 8.08%). Non infectious diseases contributed to 198 (2.56%) deaths. Among infectious diseases, pneumonia (164, 19.93 %) and Gastro-enteritis (159, 19.32 %) and among non-infectious diseases, hypothermia (108, 13.12%) and wild attack (47, 5.71%) were major contributors of mortality in the present investigation. The incidence of Gid was 8.51% (70 cases). Highest mortality was observed in spring (40.80 %)and winter (24.67 %). By adopting proper hygiene and basic managemental practices the mortality can be reduced to a large extent.
