Abstract

Research efforts have been directed at the use of non- conventional feed ingredients as a means of reducing cost of production. Cassava pellets are part of such ingredients. Thus this study aimed at evaluating cassava pellets as an alternative of maize in lactating goats’ rations. Two experiments were carried out. The first experiment (digestion trial) was carried out on three mature Baladi goats’ males to determine the nutritive value of cassava pellets. The experimental rations were designed as to replace clover hay (as a basic diet) by either 30% or 50% cassava pellets. The second experiment (feeding trial) was carried out on fifteen lactating Baladi goats to study the effects of replacing 50% and 75% of maize in the diet by cassava pellets on milk yield, milk composition, and some parameters of rumen fluid and blood plasma. The feeding trial extended from parturition until the end of week 18 of lactation. The first trial indicated that the digestibility of crude fiber was significantly decreased; however, the total digestible nutrients (TDN) were significantly increased by increasing cassava level in the diet. The nutritive value of cassava pellets in terms of TDN, digestible protein (DP), and metabolizable energy (ME) was 83.28%, 1.40%, and 10.86 MJ/kg DM, respectively. The second trial suggested that the daily fat corrected milk and the milk constituents were not significantly (p ≥ 0.05) affected by feeding cassava pellets to lactating Baladi goats. Also, neither the fermentation parameters of rumen nor the nitrogen metabolites of blood plasma was negatively affected by both cassava pellets levels. It was concluded that the use of cassava pellets as a partial replacement for maize in lactating goats’ rations would not adversely affect milk production.
