Conteúdo: | Low cost artificial rearing would benefict dairy or dual-purpose goat production. In Experiment I, 32 British Saanen male kids were purchased at 1 to 6 days of age, after receiving colostrum. After castration they were allocated to a 2 x 2 factorial design to compare age at wearning (4, 8 weeks) and cold milk substitute allowance (ad libitum, AL, restricted, R, 0.85 1/day). Milk powder (based on dried skim milk and 20 percent fat) was reconstituted to produce 18 percent solids milk. Water and pelleted concentrate (barley, 77.9 percent, soya-bean meal, 9.6 percent, fish meal, 8.0 percent, molasses, 3 percent, minerals and vitamins, 1.5 percent) were offered and ad libitum before and after weaning, and until animals were slaughtered at 36 kg live weight. Animals were individually penned indoors and bedded on straw. All animals completed the experiment. Overall growth rate (g/day) and slaughter age (days) respectively were 4AL, 212, 160; 4R, 177, 181, 8AL, 233, 145; 8R, 197, 162. Total intakes of milk powder (kg) and concentrates (kg) respectively were, 4AL, 7.3, 105; 4R, 4.1, 122; 8AL, 19.0, 79; 8R, 8.3, 108. Experiment II involving 42 kids given milk substitute ad libitum and weaned at 4 weeks, showed that type of milk substitute (20 percent fat powder, 12 percent fat powder) had little effect on milk intake, but intakes decreased with increasing milk dilution (percent solids, 17.0, 13.5, 10.0). Experiment III with 18 kids showed little difference in concentrate intake before and after weaning due to physical form, ie. whole barley plus supplement, milled barley plus supplement, milled and pelleted barley plus supplement, but dry matter digestibilities were affected, 83.1, 78.0, 77.7 percent. High mortalities (33 percent) post weaning occurred in Experiment II due to starvation. This is thought to due to individual penning not allowing kids to see each other readily and thus learn to consume dry food
