Abstract :Herd health and adaptability are of concern in animal production in the tropics because of the persistent exposure to multiple stresses of low quality and quantity feeds, heat stress, high disease, and parasite incidences, poor husbandry, and breeding practices; the combined effects of these factors is high livestock mortality. High health-related mortality has been frequently reported as the major impediment to livestock production and thus the aim of this article is to investigate the vital infectious diseases and non-infectious factors that account for the majority of deaths which is crucial in determining mortality control strategies. The study applies a descriptive, Kaplan-Meier method, and truncated regression analysis using an eight-year retrospective data spanning from 2014 to 2021 was applied for this analysis. The results indicate infectious diseases as the most important cause of Galla goat mortality. The mean monthly and annual mortality rates are higher and the pre-weaning mortality of Galla goat appeared to be one of the major constraints hampering the development of replacement stock. The risk factors considered for high mortality were the age and sex of the kids. Among the infectious diseases analyzed, bacterial, parasitic, and non-specific infectious diseases were identified as the important causes of Galla goat mortality, while the non-infectious conditions included malnutrition and thermal/cold shock. The analysis provided an improved insight into animal-health-related factors which once addressed could reduce mortality and hence optimize animal husbandry performance in Galla goat production systems. Interventions in Galla goat health and husbandry are recommended to control kids\` mortality.
