Livestock manure is an important source of nutrients for crop production in semi-arid West Africa. An assessment of the potential of manure to sustain crop production calls for an estimation of the amounts of manure that could be produced and captured and the feed resources required to maintain l...

Associations among chemical properties, in vitro digestibility and ruminal degradability characteristics of herbaceous legumes, browse species and oilseed cakes were studied using correlation analysis based on a total of 50 feedstuff samples. Chemical properties were poorly related to in vitro or...

A study was conducted to investigate the effect of inclusion of Lablab meal on growth rate, feed intake and carcass composition of Black Head Persian (BHP) lambs. Twenty-four BHP castrate sheep with average weight of 14.1 +2.7 kg were allotted randomly to four dietary treatments. Lambs were indiv...

About 60 Black Head Somali rams were used in 21-month experiment period (18 months for growth to maturity and 3 months for fattening) to investigate the effect of age at castration on growth to maturity, fattening capability after maturity and market value of fattened mature rams which had been c...

Twenty-seven Boran and 37 Boran x Friesian bulls, weaned at six months of age, were allocated to either receive supplementary diet (16 percent crude protein and 10.8 MJ/kg DM energy) during the dry season or to serve as unsupplemented controls until 21 months of age. Body weight measurements were...

Twenty intact male Mubende goats were randomly divided into five groups of four goats each. Each group was randomly assigned one of the treatments resulting into a complete randomised design. All the animals were individually fed elephant grass (E), used as basal diet, ad libitum. Treatments were...

Mixed crop-lvestock production system is the major agricultural production system in Ethiopia with a wide array of Development challenges and opportunities. One of the key challenge in improving the agricultural productivity of the system is feed scarcity and undernutrition. The major basal feed ...

The first part of the paper describes the predominant livestock production systems in sub-Saharan Africa. The second part discusses free resources available to the smallholders, feed resources available to the estate/large scale farmers, production levels of crop residues and agro-industrial by-p...

Seasonal breeding is potentially a powerful intervention affecting productivily, particularly so in semi-arid environments where seasonal differences are great; however, variability is also great, increasing the risk for such interventions. Simulation was used to examine the effects of 5 breeding...

There are various methods of measuring milk yield from goats. In the present study 84 lactating Galla goats on a Rhodes grass (Chloris gayana) hay basal diet and supplemented with 500g (as is) of a concentrate diet constituting of poultry litter (0, 15, 30 or 45%) were used to compare milk yield ...
