In addition to assessing rate and extent of gas production from fermenting forages in vitro with rumen micro-organisms, gas production methods (e.g. Theodorou et at, 1994) may be used also to study the degradation kinetics of forage dry matter and its fractions. As the substrate dry matter can be...

Information is needed on the biophysical and economic rationale for labour-demanding (and therefore, expensive) backyard animal rearing systems on smallholdings in the uplands of Java where livestock have been an integral part of highly intensive agriculture for centuries. The occurrence of high ...

Comparisons were made between 24 Ethiopian rams and 24 Galla goats for voluntary intake, feed selectivity and growth performance when offered three levels of sorghum stover. The levels observed were 25,50 and 75 g/kg live weight per day. Measurements of intake, growth and feed selectivity were ta...

Using on-farm supplementation trials with a P rich block (Phos) and a sult block (Salt), deficiency of P in White Fulani cattle in Nigeria was investigasted. There was some evidence, significant in some locations but nonsignificant overall, that P supplemented dans produced heavier calves and sup...

Maize stover is the most abundant crop residue in the central Kenya highlands and it is often the sole forage offered to dairy cattle during the dry seasons. In recent years increasing offer rates of crop residues (excess feeding) to promote selective feeding by confined animals has been shown to...

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...

The effect of dry-season supplementation of White Fulani cattle in northern Nigeria with legume standing hay (fodderbanks) was investigated. Over 430 cattle were recorded in 8 herds over 2-5 years. Fodder bank supplementation may have reduced weight losses in calves and breeding females during th...

Maize was planted at two, three or four seeds per hole with uniform spacing and either the smallest plant (S) or the second largest plant (L) was thinned from each hole after 8 and 14 weeks from the four seed plots and after 14 weeks for the three seed plots. Two plants per hole were left to matu...
