The aim of this study was to estimate the effect of diets with different energy levels on the growth performance of slow-growing chickens (so-called Korat chicken (KRC)). The KRC is a cross between a male Thai native chicken (Leung Hang…
Canola meal (CM) is a locally produced protein source that may be less expensive than soybean meal (SBM). This study evaluated the effects of replacing 0%, 25%, 50%, 75%, and 100% SBM with CM in diets for slaughter ostriches. The…
Nutrition contributes approximately 75% of the total input costs to an intensive ostrich production unit. An increase in the price of traditional protein sources thus necessitates finding cheaper alternatives. Sweet lupins were identified as a possible alternative; therefore, the effect…
A study was conducted to evaluate the effects of dietary total sulphur amino acids (TSAA) to lysine (Lys) ratio on performance of Ac layers (black-boned chicken). A total of 800 laying hens from 38 to 50 weeks old was allocated…
The effect on production performance of a synthetic or natural antioxidant and lipid saturation in the finishing diets of lambs was investigated. The four dietary treatments consisted of the same basal diet (187 g CP, 355 g NDF, and 71…
Livestock production in South Africa contributes substantially to food security. It is also a topic of public debate because of lack of knowledge and wrong information. This article aims to provide information on the worth and impact of the livestock…
The profitability of semi-extensive beef production is discussed on the basis of information collected over a 4-year period from 23 farmers from northern Natal who participated in the mail-in record system. Throughout the analysis, the performance of the group average…
A review based on recent research is presented on the production of Sanga (Nguni) cattle in South and South West Africa . The high calving rate of Sanga cattle (89,6%) compared to an average of 77,4% of four other breeds…
Levels of sheep and goat production, as well as aspects of the distribution of ownership of pigs and poultry, in three livestock-producing areas of Ciskei are discussed. Findings show low levels of production and reproduction and high mortality rates in…
Five diets were formulated on an iso-nutrient basis (approximately 12 MJ digestible energy, 16,5% crude protein, 5% non-degradable protein, 33% neutral detergent fibre, 18% acid detergent fibre, 0,8% calcium and 0,3% phosphorus) so that lucerne hay (LH) was substituted by…
Genetic and phenotypic correlations were estimated between lamb and ewe traits in a flock of Sabi sheep reared at the Matopos Research Station. Direct additive estimates of heritability were: 0.28 ± 0.04; 0. 17 ± 0.00; 0.25 ± 0.01; 0.39…
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…
The aim of this study was to evaluate the quality and quantity of cashmere produced by Boer goats in South Africa. No significant differences were found between reproductive status and qualitative and quantitative characteristics of cashmere produced by Boer goats.…
Many arid and semi-arid areas have been degraded to bare patches and interventions are necessary to restore a productive state. Fodder shrubs, both exotic and indigenous, have been used for revegetation and reclamation. Ideally the species to be used should…
