%X The effects of experimental Trypanosoma congolense infection on the ejaculate of rabbits and changes caused after treatment with Diminaveto  were investigated using 24 New Zealand White rabbits (bucks). The bucks were housed singly in standard rabbit cages and fed on specialized ration containing 10% Protein supplement, grains, legume, salt and fresh water ad libitum during the study. Data on ejaculate characteristics were collected from all the bucks in the first phase (i.e. before infection) and in the second phase (i.e. during infection, with 4.8x10(5) Trypanosoma congolense, intraperitoneally). Similar data were collected from 12 randomly selected bucks treated with 7.0mg/kg Diminaveto  following reconstitution during the third phase. Data collected were analysed using the Paired T- Test and Analysis of Variance. The infection led to significant (P< 0.05) reduction in spermatozoa motility, concentration and mass activity, with a significant (P< 0.05) increase in percentage of sperm cells with morphological abnormalities. Treatment with Diminaveto  led to improvement in all ejaculate parameters investigated. However, it was observed that the ejaculate did not attain the "before-infection" status following treatment with Diminaveto . The study showed that infection with Trypanosoma congolense in rabbits caused significant reduction in ejaculate characteristics. Treatment with Diminaveto  however led to improvement in the ejaculate though at a rate slower than that at which the infection caused the reduction. Fue estudiado en 24 conejos Nuevo zelandeses blancos, machos, los efectos de la infecci車n experimental de Trypanosoma congolense sobre la eyaculaci車n y los cambios producidos despu谷s del tratamiento con Diminaveto  . Los machos fueron colocados individualmente en jaulas de conejos est芍ndar. Durante el estudio fueron alimentados con raci車n especializada, con 10% de suplemento de prote赤nas, granos, legumbres, sal y agua fresca ad libitum. Los datos sobre las caracter赤sticas de la eyaculaci車n se obtuvieron de todos los machos en la primera fase (es decir, antes de la infecci車n) y en la segunda fase (es decir, durante la infecci車n, con 4,8x10(5) Trypanosoma congolense, por v赤a intraperitoneal). Datos similares se obtuvieron de 12 machos al seleccionados al azar, tratados con Diminaveto  7,0mg/kg despu谷s de la reconstituci車n durante la tercera fase. Los datos fueron analizados mediante t de student y an芍lisis de varianza. La infecci車n fue significativa (P <0,05) habiendo reducci車n de la motilidad de los espermatozoides, la concentraci車n y actividad de
