The top three senescent internodes of six genotypes of pearl millet (ICMV 155 Nor 155, ICMV 155 bmr, ICMV 221, ICMH 356, ICMH 94410, NCD 2) and sorghum (CSV 15, CSH 9, local yellow, ICSV 93046, ICSV 89057, ICSV 112) were used to asses the relationship between cell walls and wall components and in...
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...
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...
Post-partum reproductive function of 50 F1 crossbred (Boran X Friesian) cows under smallholder farms around Holetta were monitored using plasma progesterone concentrations and profiles to examine Ovarian activity of cows and accuracy of estrus detection. Experimental cows were observed for signs ...
Cereal crop residues (straw, chaff, etc.) are important components of maintenance rations for ruminant livestock in many parts of the world. They are especially important in small-holder crop-livestock production systems in the sub-humid, semi-arid, and arid tropics and subtropics where most of t...
Cereal crop residues are important feed resources for ruminants in developing countries. However, they are poor in nutritive value because digestible energy, crude protein and mineral contents are all low. Techniques to improve the feeding value of crop residues by chemical or biological means ha...
