A field trial of production and financial consequences of helminthosis control in sheep production in Ethiopia . We used a partial-budget analysis to evaluate profitability of different management strategies of three genotypes of sheep in a 2 x 2 x 3 factorial experiment conducted at Debre Berhan research station in the central highlands of Ethiopia . This involved two anthelmintic-treatment levels ( treated vs. non-treated ) , two supplementary nutrition levels ( protein-energy supplementation yes/no ) and three genotypes : indigenous Menz ( n=40 ) , 50 % Awassi x 50 % Menz crosses ( n=38 ) and 75 % Awassi x 25 % Menz crosses ( n=31 ) . All sheep were exposed to natural sub-clinical helminthosis challenge . Supplemented sheep were offered a concentrate mix daily on an individual basis . Anthelmintic-treated sheep were drenched with fenbendazole against nematodes and with triclabendazole against trematodes . Data were collected during the experimental period ( for 10 months from approximately 1 year of age ) on feed intake , live weight , eggs per gram ( EPG ) of faeces , packed-cell volume ( PCV ) , wool weight , and adult-worm burden . Actual market input and output prices were recorded . Supplemented sheep had significantly higher marginal profit ( MP ) per sheep than non-supplemented sheep ( ETB 33 vs. 4 ) . Likewise , anthelmintic treated sheep performed significantly better than their non-treated contemporaries ( MP=ETB 28 vs. 8 ) . The 75 % Awassi crosses were least profitable .
