| dc.description.abstract | The research was conducted at College 'of Agriculture And Environmental Sciences animal farm with the objective of evaluating the potential use of Fish offal (FO), which was regarded as a waste and polluting the environment damped at the shore by fishermen, as a protein source feed for growing 4!oiler chicks. FO of three fish species (tilapia, cat fish, and labeobarbus) was collected from the western side of lake Tana. The FO was prepared into two Local fish meals (LFMs) and one fermented fish silage (FFS). LFM was the composition of three fish species of equal proportion on DM basis. Whereas, the second local tilapia meal (LTM) was prepared from tilapia species only and the third, FFS, prepared by fermenting the three fish species of the same proportion using Effective Microorganisms (EM). The feeding experiment had four treatments: T-l (control), cornfull fatted soybean (FFSB) based, without animal protein; and FO based meals; T-2 (LFM), T-3 (FFS); and T-4 (LTM) partially substituting FFSB at 5% level. Experimental animals were 180; cne day old Hubbard Classic broiler chicks and the feeding lasted for 42 days. The experimental design we used was completely randomized design (CRD). The result showed in the entire experiment, Feed intake (Fl), body weight change (BWC) and average daily weight gain (ADG) were significantly (p < 0.05) affected by diet that T-l was lower than FO based treatment diets. During the starter period, in BWC and ADG, T1 and T-4 were the least significant (p < O. (i5) and T-3 the highest significant (p < 0.05) among all diets. Whereas, during the finisher period, T-4 was significantly (p < 0.05) the highest in BWC and ADG. There was no significant difference (p>0.05) among treatment groups in feed conversion ratio (FCR) but numerically, during the starter period, T-3 was the highest whereas during the finisher period T-4 was the highest, in efficiency. Mortality in percentage was T-1 (11.11), T-2(2.22), T-3(0) and T-4(4.44). The live body weight, abdominal fat and gizzard percentages in T-l were significantly (p>0.05) lower than FO based diets except in heart and liver weight percentages.
