Effects of supplementation of threshed sorghum top with selected browse plant foliage on haematology and serum biochemical parameters of Red Sokoto goats.

The haematological and biochemical parameters of 24 growing Red Sokoto bucks (9.00 ± 0.25 kg body weight) fed threshed sorghum top (TST) with or without five different browse plant foliage Afzelia africana (AA), Daniellia oliveri (DO), Piliostigma thonningii (PT), Pterocarpus erinaceus (PE) and Annona senegalensis (AS) supplements were studied using a completely randomized design. All haematological parameters were (P < 0.05) lower in TST-fed goats compared with TST-supplemented goats, except for mean corpuscular haemoglobin concentration (MCHC), lymphocytes and monocytes which did not follow a particular pattern. Packed cell volume, haemoglobin and monocytes were higher for AA-supplemented goats while MCHC was reduced relative to other supplements (P < 0.05). White blood cell counts were increased in DO lambs compared to other supplements (P < 0.05). Serum proteins, creatinine, alanine transaminase and alkaline phosphate were reduced in TST compared with the supplements (P < 0.05). Cholesterol was higher for PT and AA than other diets (P < 0.05). Aspartate transaminase was reduced in TST goats relative to the supplements (P < 0.05). Except for potassium which was reduced in AS (P < 0.05), all serum major minerals were similar among diets. Results indicate that the entire browse fodder are good supplements to low-quality TST, though A. africana appears to have a better supplementary effect on haematological and biochemical parameters of the goats.
