Omore, Amos O.Staal, Steven J.Osafo, E.L.K.Kurwijila, Lusato R.Barton, David N.Mdoe, N.S.Y.Nurah, G.K.Aning, G.[Market mechanisms, efficiency, processing and public health risks in peri-urban dairy product markets: Synthesis of findings from Ghana and Tanzania]Market mechanisms, efficiency, processing and public health risks in peri-urban dairy product markets: Synthesis of findings from Ghana and Tanzania

The study was carried out to identify risk factors associated with bacterial contamination of locally produced raw milk and its adulteration with water. A total of 419 respondents of different categories of milk agents in the study sites were sampled for data and milk collection in the dry and we...


Donkor, E.S.Aning, K.G.Omore, Amos O.Nurah, G.K.Osafo, E.L.K.Staal, Steven J.[Risk factors in the hygienic quality of milk in Ghana]Risk factors in the hygienic quality of milk in Ghana

Experiment 1, with rams (17.0 kg initial weight (M), and experiment 2, with steers (203 kg M), involved 2x2 arrangements of treatments to compare the effect of doubling the amount of stover offered (25 or 50 g/kg M daily) and chopping (unchopped or chopped), upon intake, selection and live-weight...


Osafo, E.L.K.Owen, E.Said, A.N.Gill, M.Sherington, J.[Effects of amount offered and chopping on intake and selection of sorghum stover by Ethiopian sheep and cattle]Effects of amount offered and chopping on intake and selection of sorghum stover by Ethiopian sheep and cattle

This research report presents an analysis of the problems encountered in the milk markets in Ghana and Tanzania. It is based on a study carried out during 1999 and 2000 to identify and quantify the public health risks and economic performance in dairy product markets in these two countries. The s...

The study was carried out to determine the extent to which antimicrobial drugs may be translocated into milk and the associated risk of exposure by consumers. A total of 394 milk samples were collected in the study sites in dry and wet seasons, and from different categories of milk market agents,...


Aning, K.G.Donkor, E.S.Omore, Amos O.Nurah, G.K.Osafo, E.L.K.Staal, Steven J.[Risk of exposure to marketed milk with antimicrobial drug residues in Ghana]Risk of exposure to marketed milk with antimicrobial drug residues in Ghana

Investigates the effect of cultivar and site of growing sorghum upon yield and composition of stover. Also studies the efects of pre-harvest leaf stripping and post-harvest storage.


Osafo, E.L.K.Owen, E.Said, A.N.Gill, E.M.McAllan, A.B.Kebede, Y.[Sorghum stover as ruminant feed in Ethiopia: Effect of cultivar, site of growth, pre-harvest leaf stripping and storage on yield and morphology]Sorghum stover as ruminant feed in Ethiopia: Effect of cultivar, site of growth, pre-harvest leaf stripping and storage on yield and morphology

The adoption of `improved' sorghum (Sorghum bicolor (L.) Moench) genotypes (i.e. drought tolerant, high grain-yielding and bird-resistant) by farmers in Ethiopia is low (Tilahun et al., 1992). Farmers prefer local, non-bird-resistant genotypes because their drought resistance and grain and stover...


Osafo, E.L.K.Owen, E.Ellis, R.H.Said, A.N.Gill, M.Sherington, J.[Stability of yields of sorghum genotypes: Implications for animal production in the tropics]Stability of yields of sorghum genotypes: Implications for animal production in the tropics

Presents results of a study conducted to determine the intake and selectivity of sheep and cattle offered sorghum stover in varying quantities and form (either chopped or unchopped). Includes data on live-weight gain, stover offered, stover intake, sheath intake, stem intake and stover refusal of...


Osafo, E.L.K.Owen, E.Said, A.N.Gill, E.M.McAllan, A.B.[Feeding sorghum stover to Ethiopian sheep and cattle: Effect of chopping and amount offered on intake and selection]Feeding sorghum stover to Ethiopian sheep and cattle: Effect of chopping and amount offered on intake and selection

Studies changes in the concentrations and composition of phenolic compounds in component parts of different sorghum varieties harvested at different growth stages and also after long time storage.


Khazaal, K.Mueller-Harvey, I.McAllan, A.B.Osafo, E.L.K.Owen, E.Said, A.N.[Effect of harvesting at different stages of growth and long term storage on phenolics in sorghum stover]Effect of harvesting at different stages of growth and long term storage on phenolics in sorghum stover
