Effect of feeding supplemental copper on performance, fatty acid profile and cholesterol of meat, and on oxidative stability of meat rabbits

Popis výsledku v původním jazyce

One hundred and four rabbits, 5 weeks old at the beginning of the experiment, were divided into four groups according to feed additive treatment. Rabbits of the 1st, 2nd, 3rd and 4th group were fed a basal granulated feed (control), basal feed supplemented with CuSO4.5H2O at 50 mg Cu.kg-1, basal feed supplemented with 150 mg Cu.kg-1, and the same feed supplemented with 100 mg.kg-1 vitamin E, respectively. Addition of Cu at 150 mg.kg-1 non-significantly increased weight gain by 9.1%. This effect was thet was the most pronouced in the first 2 weeks of fattening. In rabbits fed the highest amount of additives the lowest mortality was observed (7.7% vs 19.2% in the control). Rabbits were slaughtered at the age of 11 weeks. Neither treatment influenced proportions of saturated, monounsaturated and polyunsaturated fatty acids in lipids extracted from the loin and hindleg muscles. Effects of copper added at 50 mg.kg-1 were marginal. Copper had no effect on the oxidative stability of meat, me
