Supplementation of Wet Soya Milk Residue on Productive Performance and Nitrogen Balance of Boer x Saanen Crossbred Goats

Abstract

The objective of this experiment was to evaluate the effect of wet soya milk residue on feed intake, digestibility, growth rates and nitrogen (N) balance of crossbred goats. Fifteen Boer x Saanen crossbred male goats (5-6 month of age and 18.3 ±1.2 kg of average live weight) were divided into three group under a Completely Randomized Design (CRD), with five goats in each groups for 108 days. Three dietary treatments were commercial concentrate pellet diet (400 g), wet soya milk residue (800 g) and mixed commercial concentrate pellet diet and wet soya milk residue (200 g : 400 g), respectively. All animals were raised in the individual pen with free access water and mineral block. The goats fed ad libitum with corn stover silage as roughage source. The results showed that feeding different diets had effects on feed intake, crude protein and energy digestibility, body weight gain and N balance of goats significantly (P<0.05).  Crude protein (CP) and gross energy (GE) intake and digestibility, average daily gain and nitrogen balance of goats fed commercial concentrate pellet diet were significantly higher (P<0.05) than those of goat fed wet soya milk residue diets, respectively. Feed conversion ratio and feed cost per kg of BW gain were not significantly different among the diets. These results revealed that mixed commercial concentrate and soya milk residue could be used to replace commercial concentrate in the diet of goats which did not affect BW gain. Exploiting the use of local resources for goat production.
