Abstract

A survey was conducted to compile disease records maintained at District Livestock Service Ofices in Shyangja and Tanahun, Regional Veterinary Diagnostic Laboratory in Pokhara andAgricultural Research Station (Goat) in Bandipur. Records maintained for three years (1996-1999) were compiled in collaboration with veterinary oficers working in the districts and laboratory. Among 6094 diseases record, parasitic diseases (48.29%-63.75%) were found to be the major constraint in goat production. High occurrence of internal parasites (77.37% - 89.74%) was recorded once during autumn and again during spring. Although, infection of ectoparasites (10.26-22.63) were recorded throughout the year, the infestation was found to be high once during August and September and again during Apri1 and May. Therefore, control measures against these parasites should at least be taken twice a year first in the beginning of autumn and next in the beginning of spring seasons. Minor sugical condition (3.16 to 13.39)was in second place followed by febrile condition of unknown origin (10.2%-12.19%) was in third place. Diseases related to digestive disorder were mainly due to the over feeding of feedstuf (i.e. succulent leguminous feed stuff and concentrate feed), helminthes, coccidian parasites, and use of unclean water Diarrhoea appeared mainly during March to April (11.17 cases) and July to August (9-15%). Tympany occurred throughout the year almost in the same trend. Fern and fern- like feed stuff caused red water disease (urological diseases) in all sites. In both the sites retention of placenta was recorded to be one of the problelms which might be due to improper feeding particularly of sellenium and vitamin E deficient diet during pregnancy PPR and rabies were main infectious diseases (12.5%-70.13%). Further studies have been suggested in order to formulate an efective control strategy against internal parasites conducting a detail epidemiology of specific parasites. Nevertheless, very little work has been done on ectoparasites of goats in Nepal, hence a further study needs to investigate effectivce control measures against them. A study is needed to improve the housing and management of goat to minimize the general wound and eye infections. Further study on the etiology of respiratory diseases in goats has been suggested to study
