Recently, there has been an increased focus on developing high-energy and high-protein feeds for Hanwoo steers in Korea to reduce the fattening period and decrease production costs. The aim of this study was to investigate the effects of different starch…
Lupins are highly degradable in the rumen, and do not provide enough bypass protein for high-producing ruminant animals. The effects of extrusion on dry matter (DM) and crude protein (CP) rumen degradability of Lupinus albus and Lupinus angustifolius were determined…
Various studies on the food preferences of giraffe indicate that the leaves of the Acacia and Combretum species are the most important food items selected. The present study was aimed at comparing the chemical composition of the leaves and explaining…
Food preferences and food selection by giraffe have been extensively investigated but little data concerning the chemical composition of the preferred species are available. The aim of the present study was to determine whether the differences and seasonal changes in…
A study was undertaken to determine the relationship between the amino acid and crude protein content of maize using samples of yellow maize from the four main maize-producing areas of South Africa . After determining moisture, crude…
The effects of energy and crude protein (CP) supplementation on feed intake of lactating ewes grazing native pasture (veld) were studied during two autumn (1981 and 1982) and two spring (1983 and 1984) lambing seasons. The CP content of the…
The effects of energy and crude protein (CP) supplementation on diurnal and seasonal variations in rumen pH and concentrations of ammonia (NH3) in lactating ewes grazing native pasture (veld) were studied during two autumn (1981 and 1982) and two spring…
The effects of energy and crude protein (CP) supplementation to lactating ewes on the performance of the ewes and their lambs, while grazing native pasture (veld), were studied during two autumn (1981 and 1982) and two spring (1983 and 1984)…
While grazing native pasture, seven groups of 4 young Merino wethers received the following supplements daily via rumen cannulae: 0, 5 (Control), 15 and 30 g salt (NaCl); and 5, 15 and 30 g NaCl + 20 g crude protein…
Supplementary salt (NaCI) and crude protein (CP) were provided to young Merino wethers grazing native pasture. Twenty-eight wethers were divided into 7 groups and given the following supplements daily via rumen cannulae: 0, 5 (Control), 15 and 30 g NaCl;…
Consumption of low crude protein (CP) diets causes elevation in fat accumulation in chickens, and this effect is independent of dietary essential amino acid levels. Thyroid hormones, because of their metabolic regulatory characteristics, might be an effective factor in lipogenesis.…
Dietary selection trials were conducted on kikuyu pastures while being grazed for a period of 3,5 days in a four-week rotation, at stocking rates of 3,5 6,2 and 8,3 animals per hectare. The pasture was fertilized with 210 kg N…
The aim with this investigation was to quantify the impact of different veld condition classes, viz. poor, moderate and good on soil-water utilization (SWU: crude protein produced per unit of evapotranspiration), during four growing seasons (2000/01 – 2003/2004). Evapotranspiration was…
The aim of this study was to quantify the suitability of Boscia foetida as a fodder source for goats. Samples of leaves and twigs were taken in the Northern Cape and Limpopo provinces of South Africa. The concentrations of Ca,…
The aim of this study was to evaluate the nutritional value of Atriplex spp. for small stock production. Selected plants were harvested and analysed for crude protein, in vitro digestibility and leaf to stem ratio. Significant differences in nutritional value…
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…
Correlations were determined between the crude protein (CP) and lysine or methionine concentrations of grain from wheat (cultivar: palmiet), barley (cultivar: clipper) and triticale (cultivar: usgen 19) grown in the Western Cape region of South Africa. Twenty samples of varying…
Six indigenous (Pedi) goat wethers (18 months old) with an average body mass of25.1 kg were fed five diets, consisting of a mixture of lucerne (Medicago sativa) and teff (Eragrostis teff) in a cafeteria style arrangement (Trial 1). The diets…
