Effet de l'albendazole sur les helminthes gastro-intestinaux et la productivité des jeunes bovins de l'Adamaoua-Cameroun
Abstract
The Effect of Albendazole Treatment on Gastrointestinal Helminthes and Productivity of Weaned Cattle in the Adamaoua Cameroon. A study was conducted to evaluate the effect of Albendazole treatment on gastrointestinal helminthes and productivity of weaned cattle (9-21 months) belonging to the semi-intensive livestock production system in the Adamaoua-Cameroon. Two herds of male cattle grazing in the locality of Mbaoré were chosen after a coprological survey achieved at the end of the rainy season on 355 individuals. In each herd, 30 animals were randomly selected to constitute the experimental group (EG) and the control group (CG). EG cattle were treated with 10% albendazole (7.5 mg/kg BW) at D0. Fecal samples were collected and examined by the McMaster technique at D0 and D12 to assess the efficacy of the treatment. Thereafter, a coprological monitoring was conducted every 3 weeks from November 2013 to April 2014. A weight measuring tape was used to estimate the weight of the cattle at every faecal sampling day. Coprological examinations revealed that strongylosis, toxocarosis and trichurosis are the main gastro-intestinal helminthosis of young bovine with prevalences of 69.57%; 13.64%; 12.14% respectively. Results of the fecal egg count reduction test (FECRT) indicate a good efficacy of the anthelmintic used (FECRT>90%). Albendazole treatment at the beginning of the dry season has maintained the level of feacal egg output low throughout the dry season. The treatment with albendazole reduced the level of feacal egg gram (EPG) output to 50.99% in the EG compared to the CG (at the end of the season). A reduction of the seasonal weight loss (13.22%) was observed in the EG. However, there was no significant difference (P>0.05) of weight between the two groups.
