The objective of this study was to assess the effect of supplementation of Nigella sativa oil (NSO) as a growth promoter in broiler diets. A total of 300 unsexed one-day-old Arbor Acre broiler chicks were randomly divided into five treatment…
Six hundred one-day-old broiler chicks were used to determine the effects of Moringa oleifera leaf meal (MOLM), a probiotic, and an organic acid on growth, weights of digestive organs, and meat quality. Starter, grower, and finisher diets were formulated to…
The possibility of substituting maize for sorghum grain in fattening diets was studied in a digestibility trial with wethers and a growth study with steers. ln die digestibility trial a 6 x 6 Latin square design was used with maize,…
Sixty Merino lambs weighing 25 kg were randomly allotted to six different feeding levels as follows: ad libitum, 80%, 71%, 65%, 55% and 45% ad libitum. Individual intakes and live masses were determined weekly. From 25 - 33 kg live…
The use of ammoniated maize residue as a replacement for maize meal in the diet for fattening lambs, was investigated. Ammoniation of maize residue increased average daily DMI and ADG at the 0 and 20% concentrate levels. The feed conversions…
The effect of alkali-treated bagacillo in diets varying in proportion of bagacillo and molasses was studied in lambs. The bagacillo was treated with a concentrated solution of NaOH in a horizontal drum-type mixer to give a final concentration of 6%…
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…
Production traits of chickens of the Lesotho line, namely: body weight, body weight gain, feed conversion ratio (FCR) and mortality, were compared with four South African indigenous lines (Ovambo, Potchefstroom Koekoek, Lebowa-Venda and Naked Neck) and two exotic lines (Rhode…
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…
Data on cumulative feed intake, growth rate and chemical body constituents of 24 ostrich chicks, from a comparative slaughter experiment, were utilized to describe patterns of efficiency of feed utilization, deposition rates of protein, fat and body energy, as well…
Effects of intratesticularly administered zinc tannate (ZT) on growth performance, sexual development, slaughter, carcass and meat quality characteristics of young bull calves (-225 kg, 7 months old) were investigated. Comparisons were made across a three (treatments: ZT animals, intact bulls…
The production performance of primiparous Holstein Friesland and Jersey cows wascompared under local conditions during summer. A complete diet providing 15% crude protein (CP), 13% crude fiber (CF) and 10.8 MJ ME/kg dry matter (DM) was fed twice daily on…
Four laying strains were evaluated with regard to henday egg production, egg mass, feed conversion, mortality, Haugh units, shell thickness and percentage soiled, cracked and broken eggs produced under a battery, floor house and free-range system. This was done to…
