Abstract: One of the difficulties in successfully managing the supply and use of animal feed in sheep farming is in knowing the live weight of the sheep in the various mobs a farmer may be using. Most farmers make intuitive estimates of whether their sheep are increasing, maintaining or losing weight. A few farmers will weigh samples from the mobs, but this is an expensive and tedious operation, and consequently not carried out very often. If an inexpensive and simple method could be devised for quickly obtaining the average live weight of a mob of sheep this would markedly aid their successful management. This discussion paper contains outlines of the various methods that might be used as well as the problems with each method. There are also discussions covering the efforts made, as explained in the literature, for use in estimating the live weight of other species. This provides a means of generating ideas. The discussion paper concludes with recommendations on what appear to be the most promising approaches that might be further investigated. If such a system could be devised there is no doubt many farmers around the world would utilise it to assist in the management of their feed supplies, and consequently improve the efficient production of meat and wool.
