The voluntary feed intake of modern pig genotypes

Extract
The continued genetic improvement for lean tissue growth rate and efficiency of pig production has allowed the liberal feeding of modern pigs without adverse effects on carcass quality or food conversion efficiency, even at heavy slaughter weights (Cole and Chadd, 1989; Webb, 1989). This genetic improvement has, however, been associated with a reduction in appetite so that the food intake of modern genotypes of pigs cannot be precisely assessed from the prediction equations established for the older and fatter genotype of pigs. The present experiment was designed to measure voluntary feed intake in order to facilitate the establishment of nutrient requirements and feeding strategies for modern pig genotypes.
