Abstract

A comparison was made between three goat genotypes (100%, 75% and 50% Katjang), 4% NaOH treated and untreated rice straws fed ad libitum, and 4% NaOH treated and untreated dehydrated palm oil sludge (POS) fed at 20 g per kilogram liveweight (LW) per animal per day. A 1 kg supplement of Leucaena leucocephala was fed daily to each animal.

Average total dry matter (DM) intake and LW gain (LWG) was 48·1 g per kilogram liveweight per day and 33·4 g per day, respectively. Alkali treatment increased intake of straw (P< 0·001) and LWG (P < 0·05). Mean DM intake of straw was low, 3·8 g per kilogram liveweight per day. Treated-POS promoted lower gains (P < 0·05) than untreated-POS diets.

Mean apparent digestibility of DM, crude protein, crude fat and neutral detergent fibre was 61·8%, 64·4%, 82·2% and 61·2%, respectively. For most constituents, there were no significant differences in digestibility between alkali treated and untreated diets.

The 100% Katjang gave lower gains (P < 0·01) than crossbred genotypes. There were no signs of mimosine toxicity; mimosine in the Leucaena was 2·96% of DM.

秸秆和干棕榈油泥碱处理对不同基因型山羊采食量和生产性能的影响

试验比较了3种山羊基因型(100%、75%和50% Katjang)、4% NaOH处理和未经处理的水稻秸秆和4% NaOH处理和未经处理的脱水棕榈油污泥(POS)，每头动物每天每公斤活重(LW) 20 g。每只动物每天补充1 kg白头银合欢。平均总干物质(DM)采食量和平均体重增重(LWG)分别为每天每公斤活重48.1 g和33.4 g。碱处理增加了秸秆采食量(P<0·001)和LWG (P <0·05)。秸秆干物质平均采食量较低，为3.8 g / kg活重/ d。处理后的pos促进了较低的收益(P <0·05)。DM、粗蛋白质、粗脂肪和中性洗涤纤维的平均表观消化率分别为61.8%、64%、82.2%和61.2%。对于大多数成分，碱处理饲粮和未处理饲粮的消化率无显著差异。100%加江指数涨幅较低(P <0·01)高于杂交基因型。没有氨苄中毒的迹象;青鳉鱼的含糖量为DM的2.96%。
