Resumo:  ABSTRACT The meal of Jatropha curcas (JCM) seed is a by-product of the biofuel industry and may potentially to be used as animal feed. However, its toxicity has prevented its utilization in animal nutrition mainly due to its high concentration of phorbol esters. This study was conducted to evaluate the effects of the dietary inclusion of JCM on the growth performance, feed digestibility and internal organs development of broilers. Thirty two 48-d-old Ross 308 broiler chickens housed in 16 pens (2 birds/pen) were used in this study. Birds were randomly allocated to dietary treatments comprising four JCM levels (negative control, 25, 50, or 100 g JCM/kg of diet) for four weeks. Results showed that increasing levels of JCM had a negative impact on broiler performance, reducing live weight, weight gain, and feed intake. Treatments led to a decrease of the relative weight of testis and spleen, and to an increase in heart relative weight. In broilers fed diets containing JCM, the testis were atrophic, presenting reduced size of the seminiferous tubule, which were small and lined within active sertoli cells and rare spermatogonia. This study illustrates the negative impact of diets containing JCM on broiler performance and JCM pathological effects on several organs.
