Effect of copper sulphate supplementation on performance of broiler chickens, cholesterol content and fatty acid profile of meat

Popis výsledku v původním jazyce

Six hundred day-old male Ross 208 chickens were fed on wheat/maize - soybean meal diet and divided into 4 groups. Chickens of the 1st and 2nd group were fed diets containing 13 and 35 mg Cu/kg, respectively. Chickens of the 3rd group were fed the feed with 126 mg Cu from the 1st to the 14th day of age, then the feed with 35 mg Cu/kg till the 41st day of age. Chickens of the 4th group were fed the former feed from the start to the end of the experiment. Copper was added to feed mixtures as CuSO4.5H2O. Higher concentrations of Cu significantly (P<0,05) decreased weight gains (by 7,0 and 6,1% in the 3rd and the 4th group, respectively), and insignificantly reduced mortality of chickens (from 2,6 to 0,6-1,3%). Feed conversion was worse in chickens of the 3rd group than in other chickens (P<0,05). In 8 chickens from each group lipids of breast muscles were analyzed. Total lipid and cholesterol concentration in breast muscles of chickens of the 3rd group was significantly (P<0,05) lower than
