Abstract

The study investigated the use of dried goat rumen contents (DGRC) on growth performance of broiler chickens. Rumen contents were obtained from goats immediately after slaughter during the wet season, sundried, milled and incorporated in experimental diets at levels of 0, 5 and 10%. The 0% DGRC diet was the control. The experimental diets were formulated on iso-caloric and iso-nitrogenous principles in line with the nutritional requirements for growing broiler birds. Experimental birds were first fed on a common starter broiler diet comprising of 21% CP and 3100 Kcal/kg feed from 0 to 21 days of age; thereafter the birds (21-42 days) were allotted to the experimental treatments in a completely randomized design (CRD) with three replications. A cage with 10 birds was the experimental unit. Experimental diets were offered in the morning and evening, water was provided ad lib. Feed offered and leftovers were weighed daily, and body weight changes were recorded on a weekly basis. The results showed that birds on the 5% diet had significantly (Linear, Quadratic P<0.05) higher final body weights (FBWs), average daily gain (ADG) and better feed conversion ratio (FCR) compared to those o on diets with 0 and 10% DGRC. Apparent and ileal digestibility of nutrients was improved with incorporation of dried goat rumen contents in the diets. Sensory analysis showed that meat from birds on 5% DGRC diet had (P<0.05) more oil content and softer meat across diets. It is concluded that, use of dried goat rumen contents (DGRC) in broiler diets improves growth performance and organoleptic qualities of broiler chicken meat.

Key words: Digestibility, growth performance, rumen contents, sensory attributes.
