Responses of Growing-Female Crossbred Ettawa Goats Fed Concentrates Containing by-product of Traditional Fried Snack Industry with Different Levels of Urea

Abstract

The problem faced in West Nusa Tenggara (NTB) is lack of goats’ feed in dry season result in low productivity of the goats. Furthermore, the cost of the feed is very expensive, and therefore it is needed to nd alternative feeds which locally available, cheap and non-competitive with human needs. The purposes of this experiment was to evaluate the utilization of by-product of traditional fried snack industry (“rontokan gorengan = RG”) as a concentrate in combination with rice bran (1:1) and different levels of urea on dry matter (DM) intakes of each feeds, total nutrient intakes, water intakes, feed conversion ratio (FCR), average daily gain (ADG) and DM intake as percentage of body weight (BW) of growing-female crossbred Ettawa goats given a basal diet consisted of eld grass and banana peel. Sixteen growing-female crossbred Ettawa goats with an initial of body weight of 19±2.8 kg were allocated into four group of 4 goats each and fed one of dietary concentrate treatments containing 0%, 2%, 3% or 4% urea and arranged according to Completely Randomized Design. The results show that there were no signi cant difference (P>0.05) on DM intakes of each feeds; total nutrient intakes, DM intake as percentage of BW; water intake; ADG; and FCR. Nitrogen (N) intake was enhanced (P<0.05) by increasing level of urea in the concentrates. The goats receiving diet with 3% urea in the concentrate tended to have the best response in ADG (95.9 g/head/day) followed by the highest of DM intakes of eld grass, total DM and OM (organic matter) intakes, total N intakes and the lowest of FCR. It is concluded that adding 3% urea in the concentrate based on “rontokan gorengan” and rice bran (1:1) can maintain productivity of growing-female crossbred Ettawa goats.
