The prickly pear cochineal Dactylopius opuntiae Cockerell (Hemiptera: Dactylopiidae) is a serious pest that causes severe damage to prickly pear cactus species of the genus Opuntia. Before its introduction to Morocco no control methods were...
Efficiency Change, Technological Progress and Sources of Long Term Agricultural Productivity Growth in Selected MENA Countries
We investigate the factors that affect total factor productivity growth in MENA countries. To this end, we start first by examining levels and trends in agricultural outputs and productivity growth using Torqnovist Indexes and then computing...
Lungworm infection in small ruminants in Ethiopia: Systematic review and meta-analysis
Lungworms are important parasitic nematodes of small ruminants that colonize the lower respiratory tract and cause high morbidity and economic loss throughout the world. This systematic review was conducted with the aim of estimating the pooled...
Bio-economic analysis of dual-purpose management of winter cereals in high and low input production systems
Dual-purpose (DP) management of cereals holds promise to reduce the feed gap and to better integrate crop and livestock systems especially in drylands where forage deficit is severe. However, there is limited information on which cereal species...
Changes in the milk fatty acid profile of Awassi sheep in response to supplementation with agro-industrial by-products
Awassi dairy sheep farmers in the Middle East are facing high feed costs, particularly during the milk production season, along with large fluctuation in grain and straw prices. Incorporating agro-industrial byproducts into the diet of Awassi...
