ABSTRACT
Nutrient digestibility and blood profile of animals indicate physiological, pathological and nutritional status and can be used to determine dietary value. This 4week study determined effects of cassava grits (CG) as replacement for dietary maize on the apparent nutrient digestibility and blood profile of two strains of starter broiler chickens. Data were collected on digestibility of dry matter, crude protein, ether extract, crude fibre and nitrogen free extract as well as Packed Cell Volume, Haemoglobin, Red Blood Cell and White Blood Cell for haematology, white blood cells differentials, while Total Protein, Albumin, Globulin, Creatinine and Uric Acid were studied for serum biochemistry using 240 day old broiler chicks. The birds comprising of Arbor Acre plus (120) and Marshal Strains (120) were randomly allocated to four treatments where CG replaced 0, 15, 30 and 45% of dietary maize. At 3 weeks, 2 birds were selected per replicate for apparent nutrient digestibility study following standard procedures while blood samples (5ml) were collected from 4 birds per replicate via the jugular vein into EDTA bottles for haematology and plain bottles for serum biochemistry and analysed. Data obtained were analysed using ANOVA. Results revealed that dietary CG and strain had no significant (p>0.05) effect on apparent nutrient digestibility. Blood parameters were not significantly (p>0.05) influenced by strains and dietary treatments except (p<0.05) creatinine. Broiler chickens on 15% CG treatment had highest (p<0.05) creatinine (4.35mg/dl). Interaction between broiler strains and CG levels had no influence (P>0.05) on total serum parameters of the experimental birds. Replacement of dietary maize with CG up to 45% level had no deleterious effects on the nutrient digestibility and general well-being of starter broiler chickens.
