Summary

Three strategic anthelmintic programmes were evaluated for use in the prophylaxis of parasitic gastroenteritis in naturally infected N’Dama cattle aged 12 to 21 months at Nsukka, eastern Nigeria. Four groups A, B, C and D were used which grazed together and each consisted of seven animals. Group A was treated in April, July, August and December. Group B was dosed in April, August and December and Group C in July, August and September. Group D received no treatments. All three treatment programmes substantially reduced pasture contamination while programmes A and B also resulted in significantly improved weight gains. The potential net profit from the three programmes was 38·0 Naira, 33·10 Naira and 24·74 Naira per head respectively. The early dry season (December) treatment in Groups A and B contributed relatively little to their overall performance but would have minimised the carryover of infection to the following wet season.

Résumé

Trois programmes de stratégie anthelmintique destinés à la prophylaxie de la gastroentérite parasitaire chez des bovins N’Dama naturellement infestés âgés de 12 à 21 mois, ont été entrepris à NSUKKA, Nigeria oriental. On a utilisé quatre groupes A, B, C et D, composés chacun de sept animaux pâturant ensemble. Le groupe A fut traité en avril, juillet, août et décembre; le groupe B en avril, août et décembre; le groupe C en juillet, août et septembre; le groupe D n’a pas reçu de traitement. Tous les traitements ont réduit la contamination du pâturage de manière substantielle. Les programmes A et B ont conduit à une augmentation significative des poids corporels. Le bénéfice potentiel net des trois programmes est estimé respectivēment à 38,0 Naira, 33,10 Naira et 24,74 Naira. Le traitement de début de saison sèche (décembre) des groupes A et B a contribué relativement peu à leurs performances globales mais semble avoir diminué le partage parasitaire pour la saison des pluies suivante.

Resumen

Se evaluaron tres programas estratégicos con antihelmínticos contra la gastroenteritis parasitária en ganado N’dama en edades comprendidas entre 12 y 21 meses, en Nsukka, Oriente de Nigeria. Se utilizaron cuatro grupos de 7 animales cada uno, A, B, C, y D, los cuales pastorearon juntos. El grupo A fue tratado en abril, julio, agosto y diciembre; el B en abril, agosto y diciembre y el C en julio, agosto y septiembre. El grupo D sirvió de control. Todos los tratamientos en general, redujeron sustancialmente la contaminación de los pastos, y los tratamientos A y B produjeron aumentos de peso. La ganancia neta potencial derivada de los tres tratamientos fue de 38·0 naira, 33.10 naira y 24·74 naira respectivamente. El tratamiento al principio de la estación seca (diciembre) en los grupos A y B no contribuyeron significativamente a la productividad, pero minimizó posiblemente la infección parasitária en la siguiente estación húmeda.
