Résumé
The research urvey entitled "Effect • of non-genetic factors on • performance in Deccani sheep at organized farm" at "Punyashlok Ahilyadevi Sheep and Goat Develop ent Project, Mukhed" was carried out during year 2008-2009. To al data of 444 Deccani sheeps over• a period of 5 years (2004 to 2008) were included in the study. • The data accumulated on birth weight, 3 months, 6 m:onths, 12 months and adult weight were taken from individuals records, lambing records and breeding records. In order to accomplish the statistical analysis of data the Least Square Technique as outlined by Harv y (1976) was employed. The result obtained from this investigation found that average body weight at birth, 3 months, 6 months, 12 months and adult weight as 1.91 ± 0.01, 11.48 + 0.11, 16.65 ± 0.06, 19.48 ± 0.05 and 25.45 ± 0.17 kg, respectively Season effect were found siginificantaly affected on body weight at birth and adult age, where as non significant at 3, 6 and 12 months body weights. Period . influences significantly on adult body weight while non significant on 3, 6 and 12 months body weights. The sex effects in general were found non-significantly affected the body weights of Deccani sheep. The average sex ratio for Deccani sheep was 49.55:50.45. The colour pattern for Deccani sheep was recorded as black (55.18 %), black and white (24.32 %) and white (20.50 %). The geo-ecological situation of tract and management practices followed on the project play its role. The size of the population study indicated parameters to be considerd for improvement on development project scale. Each of this fixed effects non-signifies of their role and indicates that finding out Decca..ni germplasm on the farm needs critical care to flush out meaningful management and selection such that maximum weight gains during each season and period, could be gained. It could be further enhance by induction of the immigrants from outside within the breeding tract of Deccani sheep and pressuring the population through selection criteria. Larger population size will be essential aspect of future studie
