The study deals with the effects of the diets supplemented with vitamin E and organic selenium on productive efficiency in guinea pigs (Cavia porcellus). The study was carried out in a small animal farm at the School of Veterinary Medicine and Zootechnics of the Universidad Nacional Jorge Basadre Grohmann, Tacna, for eight weeks with 189 weaned male guinea pigs (Peru breed). They were distributed in 21 cages. The treatments consisted of a basal diet, which was the control treatment, and 6 experimental treatments (T1 to T6), which included the basal diet enriched with different levels of vitamin E and organic selenium. Twenty-seven guinea pigs were assigned to each of the seven treatment groups. Each group received a pellet-based diet plus green alfalfa to meet animal welfare requirements. At the end of the experimental period, weight gain, growth rate and feed conversion ratio were evaluated. The results of the research indicated that co-supplementation of vitamin E and organic selenium had significant effects on productive parameters, with all variables in the treatment groups superior to those in the control group.
