The homeopathy on carcasses of feedlot steers, fed with diets containing 48% or 100% of concentrate

The experiment was conducted on the premises of the Center of Animal Production (NUPRAN), Department of Agricultural and Environmental Sciences of the Midwestern State University, in Guarapuava - PR. It was used in this experiment 32 young bulls, from the Charolais breed, coming from the same herd, with an average age of 12 months and average weight of 323 kg with a standard deviation of 5 kg. The objective of the study was the evaluation of carcass characteristics and the not integrated carcass components of steers finished in feedlot, using different diets: T1-100% concentrate diet (80% of the whole maize grain + 20% protein core) ad libitum with homeopathy (100g day-1 of CONVERT H (R)); T2 - 100% concentrate diet (80% of the whole maize grain + 20% protein core) ad libitum without homeopathy; T3 - 48% concentrate diet : maize silage ad libitum + concentrate (5.5 kg animal day-1) with homeopathy (100g day-1 of CONVERT H (R)); T4 - 48% concentrate diet: maize silage ad libitum + concentrate (5.5 kg animal day-1) without homeopathy. In a general manner, the inclusion of 100 g day-1 of CONVERT H (R), did not present influences in the carcass characteristics and in its non-carcass components. The 100% concentrate diet promoted physiological performance changes on the spleen and heart of young bulls.
