英文摘要	This study aimed to assess the possible occurrence of reproductive changes in male goats associated with ingestion of Cenostigma pyramidale hay. Sixteen animals divided into two experimental groups, G1 and G2 (control group) were used. Animals in G1 received 2% of forage, based on live weight (LW), composed of 100% of C. pyramidale, and animals in G2 received 2% of Panicum maximum Massai' grass hay, based on LW. Both groups received 1% of concentrated feed supplementation based on LW, along with mineralized salt and water ad libitum. The goats were subjected to weighing, testicular biometry, and semen and blood collection every 30 days. After 120 days, the animals were castrated and their testes were collected. Testicular measurements were performed and fragments were collected for histological processing to determine the gonadosomatic index (GSI), diameter of the seminiferous tubules, height of the germinal epithelium (HGE), volumetric proportion and volume of the testicular parenchyma components, total length of the seminiferous tubules, length of the seminiferous tubules per gram of testis, and leydigosomatic and tubulosomatic indexes. The data were evaluated for normality using the Student's t-test. Data with normal distribution were assessed using analysis of variance (ANOVA) and the non-parametric data were evaluated using the Kruskal-Wallis test, both at 5% probability. Statistically significant differences (p<0.05) were observed for GSI (G1=0.48 +/- 0.08 and G2=0.34 +/- 0.09) and HGE (G1=52.95 +/- 2.99 and G2=.47.63 +/- 2.67) between treatments. Consumption of C. pyramidale hay increased LW and, consequently, testicular weight, contributing to high GSI. In conclusion, ingestion of C. pyramidale has no toxic effect on the testicular, seminal and histological parameters of goat testis. Due to its nutritional characteristics, consumption of this plant improves animal body development. Because C. pyramidale is adapted to semi-arid regions, it can be an alternative source of feed for goats during periods of shortage.
