Deanship Effectiveness In Jimma University

This research consisted of 2 phases experiment. The experiments were conducted at Kalurndistrict between October 2013 and January 2015 to evaluate the productive andrnreproductive performances of Bovans Brown (BB) and Koekoek (Kk) chicken breedsrnunder 3 seasons (cold season-CS, hot season-HSe and main rainy season-MRS) and 2rnfeeding regimes-FR (Supplemented-SU and Non-supplemented-NS). Phase I wasrnarranged as a 2x3 (2 breeds and 3 seasons) and Phase II as a 2x2x3 (2 breeds, 2 FR andrn3 seasons) factorial arrangement in CRD, having 6 and 4 treatment combinationsrnrespectively with 3 replications for each treatment. During phase I, 50 chicks perrnreplicate was reared up to 3-month age; and during phase II, 6 birds per replicate at 3-rnmonth age was distributed to 12 household farmers to be maintained up to 15-monthsrnage. For phase I: feed intake (FIg/b/d), average daily gain (ADG), feed conversion ratiorn(FCR). For phase II: body weight gain (BWG), egg production traits, the effect of breedrnand FR on GI and reproductive tracts measurements; were measured, fertility andrnhatchability were assessed, the farmer’s perception on the chicken genotypes was alsorncaptured. In addition; mortality, rectal temperature (RTOC), ambient temperature (AT)rnrelative humidity (RH) and rain fall was taken for the two phases. Except the data onrnfarmer’s perception that was analysed by descriptive statistics; SAS, (2002) computerrnivrnpackage was used for all the rest dependent variables. The result of Phase I indicatedrnthat; BB was more pronounced in FIg/b/d and the Kk breed in ADG, FCR and mortality.rnHigher ADG and RTOC, and better FCR was recorded during the HSe. BB had higherrnFIg/b/d in all the seasons. Higher ADG and mortality, better FCR in the MRS; andrnhigher RT in the HSe observed on the Kk breed. The result of Phase II revealed that Kkrnbreed, supplementation main effects and their interactions played a great role inrnimproving BWG. Koekoek, supplemented, HSe birds and their two and three-wayrninteractions were higher in RT. In TCE-Kk and in AEW-BB breeds main effect was morernpronounced than the rest of the two and three-way interaction effects. Earlier AOEL wasrnrecorded in the main effect supplemented and the interaction effects of BB and Kk breedsrndue to supplementation. Among the reason of mortality/loss, mortality due to unidentifiedrndiseases was higher. The egg type BB was superior in ovary weight, follicle number,rnweight and length of major parts of the oviduct and important digestive organs.rnSupplementation stimulated the ovary weight, follicles number, and oviduct weight andrnlength. There was significant (p
