The study was conducted to evaluate the effect of adding homeopathic products on performance and serum biochemical profile of broilers. The experimental design was completely randomized design with four treatments and eight repetitions of 20 birds each, a total of 640 broiler, males. The trataments avalied was: Control (diet without incluision of homeopathic factors), Factor Pro birds® (FP) (supplied from the 1st to 42 days old), Factor Stress birds® (FE) (provided until 14 days of life for birds), Factor Stress birds® + Factor Pro birds® (FS + FP) (FE supplied until 14 days of age, with the supply of the FP 15 to 42 days of age). The results were subjected to analysis of variance and means were compared by Tukey test at 5%. The inclusion of homeopathics products increased the mean weight and weight gain of birds to 21 days of age. At 42 days, were determined greater productive efficiency and viability (%) for broilers consuming diets with the addition of PF and EF, respectively. There were no statistical differences between the serum biochemical parameters total protein, cholesterol, alkaline phosphatase, and transaminases GOT and GPT, however, there was a decrease in cholesterol levels for broilers fed diet containing FP. It is concluded that homeopathic factors do not affect the performance of broilers at 42 days of age, however, improve the carcass yield, productive efficiency, viability and reduce serum cholesterol levels.
