Effects of bread in the diet of fattening pigs reared extensively

We evaluated the effects of adding unsold bread (i.e. a low-cost product) to the diet of fattening crossbreed pigs reared outdoors. A total of 27 Goland sows were allocated to three homogeneous groups and fed with different diets: A feed + 15% bread; B feed + 30% bread; C the control group (only feed). The pigs were weighed individually on arrival at the farm, at the start of the experiment, and at slaughter. Growth performance and carcass traits were evaluated. Two sections from the loin were taken from each animal and the following were analyzed: dry matter, crude protein, lipids, ash, fatty acids, pH, color, water-holding capacity, and lipid oxidation. Group B had higher gains and slaughter weights than group C, while group A showed intermediate values. The results show that a diet containing 30% bread facilitates weight gain of pigs, without affecting meat quality and nutritional value.
