[Quality of meat from lambs fattened on feed mixtures with added bacterial protein].

Physico-chemical, microbiologic, and histologic investigations were carried out with meat and parenchymal organs of lambs offered feed mixtures with a supplement of bacterial protein on methanol basis in fattening the animals up to 35 kilograms. The addition of 5 per cent bacterial protein which replaced in terms of protein equivalent 60 per cent of the sunflower oil meal and totally the amount of urea in the mixtures had no negative effect on the physical and chemical composition of the meat and its biologic value. Histologically, no degenerative changes in the skeletal muscles and parenchymal organs were found. There was hypofunction of the thyroid gland in the test lambs. No pathogenic and occasionally pathogenic organisms were found in the sampled meat and organs.
