Bioassay of acaricide resistance on three common cattle ticks was carried out on four farms in Holotta area, Central Ethiopia, using a standardized FAO Acaricide Resistance Test Methods. Larval progeny of Boophilus decoloratus, Rhipicephalus e. evertsi and Amblyomma variegatum were subjected to l...

This study examined whether work applied at different stages of lactation had any effect on reproduction of cows under two feeding regimes. Twenty-four F1 crossbred dairy cows (12 Friesian X Boran and 12 Simmental X Boran) were allocated one of two diets (H + 3: natural pasture hay + 3 kg concent...


Zerbini, E.Gebre-Wold, A.[Effect of work applied at different stages of lactation on milk production, reproduction and live-weight change of F1 crossbred dairy cows used for draught]Effect of work applied at different stages of lactation on milk production, reproduction and live-weight change of F1 crossbred dairy cows used for draught

Improvement of the nutritive value of dual-purpose sorghum (Sorghum bicolor (L.) Moench) stover is an important objective for the semi-arid tropics where sorghum crop residue is extensively used for livestock feed. To identify the relative importance of genetic and environmental sources of variat...

A feeding system, draught cows, disease/work interactions and animal power introduction in a farming system are reviewed. A new feeding system for draught animals is described which enables feed requirements and the effects of work on liveweight and milk yield to be calculated. Recent data on the...
