This study was conducted to assess the effect of nettle supplementation on heat-stressed broiler performance and physiology. A total of 540 Ross-308 broiler chicks were randomly assigned to nine treatments each with six replications of 10 birds. Three contents of…
The effect of the extrusion of canola oilcake meal (COM) and crushed sweet lupins (CSL) with molasses on the dry matter (DM) and crude protein (CP) degradability was determined in situ. Locally sourced (SOILL Moorreesburg, South Africa) COM and CSL,…
A study was conducted to evaluate the effect of yeast peptide supplementation on growth performance, nutrient digestibility, and blood metabolites in geese. One-day-old Sichuan white geese (n = 300, 95.16 ± 1.98 g) were randomly assigned to five dietary treatment…
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…
The objective of this study was to evaluate the nutritive value of maize stover silage diets containing pig excreta (PE), poultry litter (PL) or urea as nitrogen (N) sources, and sugarcane molasses (MOL) or bakery by-products (BBP) as energy sources.…

Metabolic adaptations and digestive ability were integrated to explain the ecological efficiency of the hyrax (Procavia capensis). Metabolic rate was shown to decrease linearly with a drop in ambient temperature, but at a lower rate than an animal of equivalent…
Reasons for low productivity of sheep grazing barrel medic (Medicago truncatula) were investigated based on studies of intake and digestion. Pasture analysis showed that barrel medic represented only 13 to 30% of the diet selected and this was similar to…
Anatomical and nutritional adaptations were studied in four African rodents (Cricetomys gambianus, Mystromys albicaudatus, Thallomys paedulcus and Saccostomus campestris). The stomachs of all species are markedly sacculated with a highly modified corpus containing either numerous papillae or several diverticula and…
A study was undertaken to examine the digestion and fermentation in the capybara (Hydrochoerus hydrochaeris) fed either forage or a predominantly concentrate diet. The large volume of digesta (3,66 and 2,73 kg), pH (6,6 and 6,3), NH3 - N (78…
The aim of this experiment was to determine the site and extent of digestion of nutrients in sheep fed broiler litter alone (100% litter treatment), broiler litter plus 7.5% sugarcane molasses (92.5% litter treatment) and broiler litter plus 15% molasses…
Non-ammonia nitrogen (NAN) passage to the small intestine and disappearance of NAN in that organ have been studied in multi-cannulated sheep on pasture or fed indoors. Forages under investigation included a number of subtropical grasses, foggages and hay, temperate grasses,…
Twelve steers fistulated in the rumen and duodenum were allocated to one of three diets and fed 80 g DM/kg W0.75/d. The diets consisted of about 80% maize meal, 11% cottonseed hulls and either 1.44% urea (Treatment A), 0.96% urea…
The effect of heat processing on ruminal degradation, intestinal digestibility (UDP-D) and absorbable amino acid (AA) profile of cottonseed oilcake (CSOC) and soybean oilcake (SBOC) was calculated. CSOC and SBOC were roasted in a drum roaster at six temperature settings…
Different protein-energy ratios in feedlot diets may effect several combinations of amounts of amino acids and glucose available for absorption in the small intestine. In this regard, the effect of protein concentration and degradation, and energy content of the diet…
Multivariate prediction models were developed from the results of three divergent trials with multicannulated steers. Diets differed in composition and physical structure. Energy contents varied from 10 to 13 MJ ME/kg DM, starch from 20 to 62%, CP from 102…
