Eight beef breeding schemes, requiring different levels of performance recording of young cattle, were evaluated for their genetic gains and economic parameters: costs, return and profit. A population 20 times the size of the breeding unit was assume

Lamb and mutton carcases from abattoirs, and from wholesale and retail outlets, were studied to provide information on the characteristics of typical commercial Australian sheep carcases. Characteristics examined were the weight, length (pubic symphy
