Coccidiosis is a disease caused by protozoa of the genus Eimeria which seriously affects young rabbits. Treatment based on the use of anticoccidial drugs is increasingly ineffective due to the rapid emergence of resistant strains of coccidia and the high cost of drugs. Consumer demand for rabbit products without chemical residues led to a growing interest in the use of medicinal plants as an alternative treatment for coccidiosis. The present study was carried out during the period of August to December 2020 to assess the anticoccidial effect of hydro-ethanolic extract of leaves of Artemisia annua L., in young rabbits. The antiparasitic efficacy of Artemisia extract was tested on 15 young rabbits (whose age varied between 7 and 9 weeks) divided into 5 lots of 3 animals. The average weight of these animals was 790 g. The results of this study show that the feces samples and the weight of young rabbits before administration of the treatment and the coprological examination (every 7 days for 4 weeks) show a fecal excretion reduction rate (FECRT) of 55.13% in the lot treated by sulfonamide. On the other hand, in animals received treatments extract of the leaves of Artemisia annua L., the average FECRT is evaluated at 69.64%, 79.22%, and 96.36% for respective doses of 400, 800 and 1200 mg/kg bodyweight and proves their anticoccidial effect. Furthermore, the variation in mean Eggs Per Gram (EPG) of coccidia and the average weekly weight gain (AWWG) of each lot were significant in the lots treated with hydro-ethanolic extract (P 0.05). The greatest reductions in oocystal excretion and weight gain obtained were those of lot 5, treated at 1200 mg/kg of hydro-ethanolic leaves extract of Artemisia annua L.

The study of the effect of added quantity of the essential oil of Callistemon viminalis on the in vivo digestibility of Pennisetum clandestinum and some biochemical parameters on the West African Dwarf goat was conducted with nine old West African Dwarf goats. After the adaptation period, each animal received 900 and 100 g/day of Pennisetum clandestinum hay and concentrate respectively, associated with 0, 100 or 200 mg essential oil/kg of DM. The samples of 100 g of each ration, faeces and 10 ml of urine were collected and analyzed for chemical composition and the evaluation of ingestion and digestibility. Also blood samples were obtained from jugular vein of all goats after in vivo digestibility test for the dosage of biochemical parameters. The results of this study show that the ingestion of dry matter, organic matter and the fibers were significantly (p 0.05) higher on the goat with the ration FPc + HECv200. The digestibilities of these same components were equally higher with the ration FPc + HECv200 (71.00% and 69.00% respectively for the dry matter (DM) and organic matter (OM)). Retained (5.64 g/j) and digested (51.33) nitrogen were significantly (p 0.05) higher with the ration FPc + HECv200. The values of blood metabolites studied increased significantly (p 0.05) with added quantity of essential oil in the rations, except for albumin, globulin, glucose and the low-density lipoprotein (LDL). In general, the incorporation of essential oils of Callistemon viminalis in the ration improved ingestion, digestibility and biochemical parameters on the West African Dwarf goat.
