The objective of this study was to evaluate the effects of pasture height at pre-grazing of Massai grass on the quality of available forage, forage intake and the performance of lambs raised for meat production. The treatments consisted of four…
The effect of alkaline hydrogen peroxide (AHP) treatment and urea supplementation on the feeding value of wheat straw was investigated in a 2 x 2 factorial experiment with sheep. Bales of wheat straw were dipped for a period of 24…
Experiments were conducted to examine the difference in intake between hay and silage made from lucerne (Medicago sativa) and whether these differences could be accounted for in terms of physical rumen characteristics. Voluntary intake was lowest on lucerne hay ensiled…
Straw is a major by-product of the grain industry. Indirect ammoniation by urea to improve the nutritive value of straw was investigated. Ammoniated and untreated wheat straw were compared in a 2 x 2 factorial experiment at CP levels of…
Groundnut and bean haulms were evaluated as feeds for indigenous Malawian goats. Generally, the results showed that the nutrients in the bean haulms were better digested and utilized by the goats than those in the groundnut haulms. However, provided that…
The ammoniation of wheat straw by urea in a stack method was investigated and compared to urea supplemented and untreated straw in an intake and in vivo digestibility trial. Ammoniation and supplementation significantly (P ≤ 0,01) improved the mean daily…
The utilization of urea-supplemented and ammoniated barley straw in sheep. Barley straw treated with urea (75 kg/ton straw) and with anhydrous ammonia (30 kg/ton straw) by the stack and oven methods were compared with urea-supplemented barley straw in an intake…
Comparison of enriched barley, wheat, triticale and maize for the fattening of early-weaned lambs. Alkali-ionophoreenriched barley, wheat, triticale and maize were evaluated as diets for the fattening of early-weaned (ca 10 weeks) SA Mutton Merino lambs kept under feedlot conditions.…
Lucerne hay (LH) was substituted by urea-ammoniated wheat straw (AWS) in four lamb-growth diets, all containing 60% roughage. The ratio of LH to AWS was 60: 0, 40: 20, 20: 40 and 0: 60 in the respective diets, which were…
Utilization of enriched barley and a wheat/barley mixture in feedlot rations for early weaned lambs. Whole barley and a wheat/barley mixture (67: 33) were enriched with either a locally composed supplement (containing urea and minerals absorbed into the grain, with…
A study was conducted to determine the effect of dietary energy and protein concentrations in a 3 x 5 factorial experimental design on the performance of growing and finishing ostriches. Energy concentrations amounted to 8.5, 10.5 and 12.5 MJ ME/kg…
