The study was conducted to investigate the effects of different levels of buckwheat seed (BWS) with black cumin seed (BCS) supplementation on the performance, serum lipid profile and intestinal bacterial flora in broiler chicks. One hundred and twenty day-old Cobb-500…
In recent years there has been increased interest in the production of novel functional foods by utilizing eco-friendly materials and methods. Therefore, the present study was undertaken to determine the effects of dietary spirulina (Spirulina platensis), a blue-green microalga, on…
Twenty-six-week-old laying hens (90 Lohmann Classic Brown) received dietary treatments containing canola and linseed oil at 2% inclusion levels and a control diet for 21 days. The 2% dietary linseed oil, which had higher total polyunsaturated fatty acids (ΣPUFA) and…
The intestinal morphology and pH of digesta of broiler chickens at 35 days old were studied. Birds were reared on these dietary treatments (T). T1, positive control, contained 668 g salinomycin and 500 g zinc bacitracin per kg of feed…
This experiment was conducted with 480 Hubbard JA 957 one-day-old broiler chicks to determine the effects of adiCox®AP, a plant coccidiostat, and monensin on production parameters and meat quality. The birds were randomly allocated to three experimental diets: (A) with…
The present study was conducted so that the possible effects of thermally-oxidised dietary oil and vitamin E supplementation could be determined on the performance, lipid peroxidation, antioxidant defence system and some blood and meat quality traits of broilers. Broilers were…
Levels of bromine (Br) in groundwater that exceeded guideline concentrations of 0.01 mg/L prompted the investigation of the effect Br and iodine (I) in drinking water on the production parameters of broilers. The research was done over a 42-day growth…
When least-cost diets, based on metabolizable energy (ME) values are formulated one assumes that the ME values allocated are additive, so that the sum of the individual ME values will represent the ME value of the diet. An experiment was…
Thirteen feed ingredients, representative of those used in the feeding of poultry and pigs in South Africa, were assayed for apparent and true metabolizable energy content (AME and TME), with at least 60 determinations being made on each ingredient. The…
Evaluation of different commercial processing methods on the nutritional value of poulty byproduct meal. Poultry byproduct meal consisting of 5 volumes of feathers, 2 volumes of offal and 1 volume of blood, was processed in three different ways and evaluated…
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…
No difference in protein quality was noted between three species of earthworms, as evaluated by net protein utilization and relative nutritive values in growing chickens. Similar growth responses per g nitrogen intake were obtained for the earthworm meals, a broiler…
The aim of this study was to determine the chemical composition and digestibility of cowpea in poultry diets. Three cowpea cultivars, Glenda, Agrinawa and Indigenous were evaluated. The cultivars showed a wide range of protein contents (253.47 to 264.27 g/kg)…
Experiment I was carried out with 220 one-day-old broiler chicks to evaluate the effect of 11 different levels of vitamin E supplementation (viz. 0 to 200 mg α-tocopheryl acetate/kg diet) on the production performance of broilers and oxidative stability of…
Hulless barley contains more digestible nutrients than do whole barleys due to a lower content of indigestible fibre, but also contains a higher concentration of ß-glucans. The chemical composition and apparent metabolisable energy (AME) of five cultivars (3, 7, 12,…
Samples of sweet yellow lupins (Lupinus luteus; n = 4), broad leaf lupins (Lupinus albus; n = 12), narrow leaf lupins (Lupinus angustifolius; n = 8), faba beans (Vicia faba; n = 2), field peas (Pisum sativum; n = 4)…
The productive performance of major genes for feather reduction (naked neck and frizzle) and body size reduction (dwarf) in a dual-purpose layer strain was evaluated in the subtropical coastal region of southeast Africa (Maputo, Mozambique). The experimental material consisted of…
Day-old Amberlink pullets were fed chicken starter mash for the first seven weeks of age. Group A was choice-fed with pelleted protein concentrate, whole yellow maize and limestone powder from seven to 16 weeks of age. Group B received the…
Different amounts of hull were removed from sunflower oilcake to obtain oilcake with a protein content of 40% (SFOC 40), 42% (SFOC 42), 44% (SFOC 44) and 46% (SFOC 46). respectively. The increase in crude protein content from 40% to…
