RESUME
Méthodologie et résultats : Vingt-quatre (24) lapins âgés de 5 mois environ et pesant entre 2,01 et 2,78 kg ont été répartis en 4 lots comparables de 6 lapins chacun. Ils ont été traités pendant 60 jours avec différentes doses d’Amprolin-300 ws via l’eau de boisson : 0 ; 30 ; 60 et 110 mg/kg de poids corporel. Les résultats obtenus ont révélé que la consommation d’eau a significativement (p<0,05) diminué chez les lapins traités aux doses 60 et 110 mg/kg de poids corporel par rapport aux témoins. Le gain de poids et le gain moyen quotidien ont diminué de manière significative (p<0,05) chez les animaux traités aux doses 30 et 60 mg/kg de poids corporel par rapport aux animaux du lot témoin. Par contre, l’indice de consommation a diminué de façon significative (p<0,05) chez les animaux témoins et chez ceux qui ont ingéré la plus forte dose d’Amprolin-300 ws (110 mg/kg de poids corporel) comparé aux lapins traités avec les doses 30 et 60 mg/kg respectivement. Le pH de la semence a significativement (p<0,05) augmenté chez les mâles traités aux doses 30 et 60 mg/kg de poids corporel par rapport Aux mâles du lot témoin. La motilité individuelle et la concentration des spermatozoïdes ont diminué de manière significative (p<0,05) chez les lapins qui ont ingéré la plus forte dose d’anticoccidien par rapport aux lapins témoins.
Conclusion and application des résultats : Ainsi, à la dose de 110 mg/kg de poids corporel, l’Amprolin-300 ws a réduit la consommation alimentaire, le gain de poids, le gain moyen quotidien, le poids spécifique et le pH de la semence. Cette dose a également inhibé la spermatogenèse et réduit le pourcentage de spermatozoïdes mobiles. Son usage devrait donc être règlementé.

ABSTRACT
Methodology and results: Twenty four (24) rabbits aged 5 months and weighing between 2.01 and 2.78 kg were divided into 4 comparable groups of six rabbits each and treated for 60 days with different doses of Amprolin-300 ws from drinking water: 0, 30, 60 and 110 g/kg of body weight. The results showed that water consumption was significantly (p<0.05) decreased in rabbits treated with 60 and 110 mg/kg of body weight of Amprolin-300 compared to control rabbits. Body weight gain and average daily gain decreased significantly (p<0.05) in animals treated with 30 and 60 mg/kg of body weight compared to control rabbits. On the other hand, feed efficiency decreased significantly (p<0.05) in control animals and those who ingested the highest dose (110 mg/kg of body weight) compared to rabbits treated with 30 and 60 mg/kg of body weight respectively. The pH of semen increased significantly (p<0.05) in animals treated with 30 and 60 mg/kg of body weight compared to control animals. Individual motility and sperm concentration decreased significantly (p<0.05) in rabbits who received the highest dose of Amprolin-300 compared to control rabbits.
Conclusion and application of results: Thus, at the dose of 110 mg/kg body weight, Amprolinws-300 reduced in male rabbit, food consumption, body and average daily weight gain, specific weight and pH of semen. It inhibited spermatogenesis and reduced sperm mobility. Therefore its use should be regulated.
