Carcass traits and meat quality of male lambs fed monensin or lasalocid.

Male lambs, crossbred Merino × Ille de France, were fed a diet supplemented with 31 mg monensin or 32 mg lasalocid per kg of feed dry matter from an initial body weight of 23·6-23·9 kg to the slaughter weight of approximately 40 kg. Carcass traits and meat quality were evaluated after slaughter; the values obtained were compared with those of the control group fed the same diet without the ionophore supplement. There were few significant differences among the individual groups in carcass value, sensoric and technological properties of meat and of its composition.

[Characteristics of the meat of cattle with cysticercosis due to experimental infection with the eggs of the tapeworm Taenia saginata and treated with praziquantel].

Eleven test and control bullocks of the Bohemian Spotted breed were studied for the effect of cysticercosis and their treatment with praziquantel on the properties of meat and fat. As found, the disease affected the composition of meat and fat and some of the studied characteristics and technological properties of meat. Although the measles disappeared after treatment, they were not resorbed.

[The effect of adding dried swine manure to the diet of laying hens on the quality of their meat].

Two groups of laying hens (eight hens in each group) were given dried pig faeces at a concentration of 2.5% and 5% for six months and at a concentration of 5% and 10% for another five months. No signs of health disorders ascribable to the tested diet were found by the premortal examination of the hens and post-mortal veterinary inspection of the carcasses and organs of the slaughtered birds.

[The effect of Ridzol P used in pig fattening on carcass characteristics and meat quality].

The meat and fat of slaughter pigs given diet with Ridzol P (60 mg per kg of feed) were studied. During the veterinary examination the additive was not found to have any adverse effect on the health of the animals. Judging from the studied meat and fat characteristics, there were no significant differences in the nutritive and technological value of the meat of the pigs given feed with Ridzol P, as compared with the controls.
