Popis: A study was conducted to evaluate the effect of feeding raw or parboiled rice offal diet on rumen metabolite and haematological characteristics of bulls.20 Bunaji bulls aged 2-3 years with live weight 210- 249kg were allotted to five dietary treatments having Four bulls per treatment in a 2x2 factorial arrangement with a common control. Feeding trials lasted 90 days. Rumen fluid was collected at 0, 2, 4 and 6 hrs intervals to determine the rumen pH, rumen ammonia nitrogen (RAN) and rumen total volatile fatty acid (TVFA) for all the bulls. Blood sample were obtained at the beginning, middle and end of the feeding trial to determine haematological parameters. A concentrate and basal diets of Digitaria smutsii were offered at 2% body weight. The CP contents of the experimental diets vary between 19.69 and 20.44% while the ME ranged from 10.86 to 11.16MJ/kg DM. Rumen parameters were not significantly (P>0.05) affected by rice type but significantly (P 0.05), but differed (P 0.05) on rumen pH and TVFA at different sampling time. However, significant (P 0.05) with rice offal type. Blood glucose was however significant (P 0.05) difference for all the haematological parameters measured for Animals on varying levels of inclusion of raw or parboiled rice offal. It was concluded from this study that raw or parboiled rice offal may be used to replace up to 30% of maize offal as source of energy in the diet of Bunaji bulls without any detrimental effect on rumen metabolite and haematological composition of the bulls. Hence it can be adopted by farmers. Keyword: Bunaji bull, haematological composition, rice offal, Rumen metabolite.
