Extract

Full-fat rapeseed (FFR) is a nutrient rich product (containing about 400 g/kg oil and 180 g/kg ideal protein) and is used in pig diets at low inclusion rates (5 to 10%) as an energy supplement. Progress in the development of rapeseed varieties with lower levels of antinutrients and recent changes in subsidy payment have promoted interest in increased feeding of whole milled rapeseed to pigs. At higher levels of dietary inclusion, this may result in the problem of fat softness in the carcass as rapeseed oil contains high levels (32 g/100 g) of polyunsaturated fatty acids (PUFAs). However, this may be avoided by early withdrawal of FFR from the diet to allow mobilisation of PUFAs from body fat before slaughter. The aim was to evaluate the effect of inclusion rate and withdrawal of FFR on the performance and carcass fatty acid profile of finishing pigs.
