Meat and Bone Meal for growing-finishing pigs


A fattening experiment was conducted with 60 individually fed pigs to investigate the use of meat and bone meal (MBM). The initial weight of the animals was 30 kg and they were divided into 4 groups with 15 animals each. Group 1 (control group) was fed a commercial all-mash fattening feed containing no MBM. In group 2, 4 % and 3 % MBM were included to fattening feeds I and 11, respectively, to replace soybean meal. The addition of MBM for groups 3 and 4 was 8 and 12 % to fattening feed land 6 and 9 % to fattening feed 11, respectively.

The content of the most relevant nutrients was kept equal for all groups, but the diets were not supplemented with amino acids which resulted in a reduced content of lysine, methionine and cystine, tryptophan and threonine through the incremental inclusion of MBM.

Traits of fattening and slaughter performance and of meat quality were looked at. The diets of group 4, which contained 12 and 9 % of MBM, had a significantly negative effect on the average daily gain and feed conversion (about 7 %). No differences were observed in all the other characteristics.

The supplementation of essential amino acids is necessary when MBM is used.
