Goat meat production: Present status and future possibilities

The bulk of the world's goat population is found in South-East Asia and Africa, where goats are the major source of meat production. Unfortunately, lack of an organized goat meat industry and marketing structure in developing countries is primarily responsible for their poor export earnings compared to those in developed countries such as Australia and New Zealand. Goat meat is leaner than meat from other domestic red meat species as well as being comparable in terms of its nutritional constituents. Furthermore, there are few, if any, religious or cultural taboos limiting the consumption of goat meat. Development of a carcass grading system and a suitable infrastructure in developing countries are some of the key requirements needed to establish a sustainable goat meat industry in the world. With an increase in demand by consumers for low-fat red meat alternatives, the future of the goat meat industry looks promising.

Lot-fed goats - the advantages of using an enriched environment

By reducing the stress associated with high stocking density in a feedlot it is likely that goats will utilise their feed more efficiently and suffer fewer health problems. One possible method of reducing stress is to enrich the feedlot environment. In a feedlot of 160 castrated goats (average weight 24.6 +/- 2.6 kg), 2 types of feedlot structures were compared; a typical feedlot and an 'environmentally enriched' feedlot, and goats stocked at 2 densities; a high stocking density (1667 goats/ha) and a relatively low stocking density (897 goats/ha). Over a 42-day period, environmental enrichment (old car/truck tyres and wooden railway sleepers to climb on and PVC piping to mouth and butt) increased weight gain by 83% (P = 0.04) and reduced the occurrence of inanition by 36%. Aggressive behaviour at the feed trough was reduced by 30% (P = 0.03) in pens of lower density when compared with pens of higher density. We conclude that lot feeding goats in environmentally enriched surroundings will increase feed conversion and reduce the number of non-eaters when compared with typically bare pen structures. Doubling in liveweight gain of goats within enriched feedlot surroundings when compared with typical structures shows promise as a cost effective, animal-welfare-orientated practice.

Primal joints and hind-leg cuts of entire and castrated Javan Rusa (Cervus timorensis russa) stags

The effects of castration on the primal joints and the cuts of the leg joint of Javan rusa (Cervus timorensis russa) stag carcases was investigated at three slaughter ages (13, 19 and 25 months). Castration reduced the weights of some primal joints in the 19- and 25-months age groups, but not at 13 months. At 19 months, the neck, and neck plus chuck, were heavier by 35 and 17% respectively in entires (P < 0.05), and at 25 months entires had heavier carcases, shoulder, forequarter and hindquarter (P < 0.05). The leg and saddle joints were approximately 39 and 18% of the side, respectively, for both treatments and all ages. The proportions of the neck, and neck plus chuck, were higher (P < 0.05) in 19-month old entires than castrates. There were few significant differences between treatments in the weight or proportion of the hind leg cuts at any slaughter age, but in the 25-months group the silverside was 8% (P < 0.05) heavier in entires. In both castrates and entires, there appeared to be an increase in the percentage of the rump as the animals grew from 13 to 19 months of age. (C) 2001 Elsevier Science Ltd. All rights reserved.
