Abstract

This study aimed to investigate whether the substitution of dried brewers’ grains (DBG) with urea treated ensiled cowpea husk (UTECH) at a high level of up to 70% causes voluntary feed intake reduction and has detrimental effects on animal welfare. Eighteen healthy growing intact male goats about 10 months old, with an average initial live weight of 13.40 ± 0.59 kg, were randomly allocated to one of the following three treatments: (i) 30% cassava peel meal (CPM) + 70% DBG (0% UTECH), (ii) 30% CPM + 35% DBG + 35% UTECH (35% UTECH) and (iii) 30% CPM + 70% UTECH (70% UTECH) in a completely randomized design. Daily intakes of dry matter, crude protein, organic matter, crude fibre, total carbohydrate and neutral detergent fibre were not (P>0.05) affected but intake of ether extract decreased linearly and quadratically (P<0.001), while non-fibre carbohydrates intake increased linearly (P=0.001) with increasing UTECH proportion in the diet. Both lymphocytes (P=0.018) and neutrophils (P=0.030) showed quadratic trends but other haematological parameters and serum electrolytes were similar among the diets. All the studied haematological parameters and serum electrolytes of the goats were within the established ranges for healthy goats. The results of the study show that urea treated ensiled cowpea husk had no deleterious effect on the voluntary intake and health status of the experimental animals and can be used up to 70% for sustainable ruminant production.
