(University of Pretoria, 2017)In conditions where supplementation of poor quality diets is a major challenge, forage legumes such as Sericea lespedeza can be a good alternative supplement for protein at lower cost than most commercial concentrates. ...
-
(University of Pretoria, 2017)The overall aim of the study was to study the effects of starch and urea supplementation on roughage intake, digestibility, and microbial nitrogen synthesis (MNS) in sheep fed low-quality Eragrostis curvula hay (< 3% CP, ...
-
(University of Pretoria, 2017)This study investigated the effects of electrical stimulation and delayed chilling on carcass and meat quality of indigenous and Boer goats in South Africa. Ten goats per breed were randomly selected from typical indigenous ...
-
(University of Pretoria, 2017)Through the measurement of grinding energy, the possibility exists to predict forage fragility as related to the chemical composition of forages. It is also possible to predict a potential relationship between forage ...
-
(University of Pretoria, 2017)Globally agriculture and livestock producers have come under increasing pressure over the environmental impact of production systems. The objectives of this study were to re-calculate the direct methane (CH4) and nitrous ...
-
(University of Pretoria, 2017)Commercial game breeding practices place immense pressure on the selection of antelope species with long horns and improved genetics in order to maximise their monetary values. Current hunting policies are aimed at the ...
-
(University of Pretoria, 2017)It has long been recognised that, as part of a balanced, moderate diet, animal source foods (ASFs) offer a wide range of benefits to human health. For many years our ancestors made ASFs part of the human diet by following ...
-
(University of Pretoria, 2016)The harmful health effects related to TFA intake are specifically those associated with coronary heart disease (CHD), cardiovascular disease (CVD) and related diseases (EFSA, 2010; Judd et al., 1994; Mensink & Katan, 1990). ...
-
(University of Pretoria, 2017)The purpose of this study was to quantify the nutritive value of two veld types in the Northern Cape and also to identify limitations regarding animal production directly from the natural pasture. The two veld types were ...
-
(University of Pretoria, 2017)Protein remains one of the most expensive nutrients to deliver in the pig diet. Theoretical benefits of supplementing protease enzymes include formulating diets with lower crude protein levels, using alternative raw materials ...
-
(University of Pretoria, 2016)Read abstract in the document
-
(University of Pretoria, 2016)Ractopamine hydrochloride (RAC) has been used in the pig production industry for over 30 years. RAC is a beta-adrenergic agonist which is supplemented in the feed during the last 28 days prior to harvesting in finisher ...
-
(University of Pretoria, 2016)The efficacy of exogenous phytase and protease, alone and in combination, or in combination with AGP, zinc bacitracin on performance and intestinal morphology in broilers was tested. Broilers were fed a diet containing ...
-
(University of Pretoria, 2016)The in vitro culture environment of cattle embryos can compromise the survival of developing embryos resulting in cell apoptosis. Detection of cell apoptosis is important for determining embryonic quality and reducing ...
-
(University of Pretoria, 2016)The aim of this study was to evaluate the effect of freezing methods and post-mortem ageing days for frozen beef m. longissimus lumborum (LL) on colour, moisture characteristics; characteristics and sensory characteristics. ...
-
(University of Pretoria, 2017)Recently, intense broiler selection for rate of body weight gain and improved feed conversion has been an area of focus for poultry breeders. Modern broilers achieve slaughtering age at 60% less time than 40 years ago. ...
-
(University of Pretoria, 2017)Indigenous chickens (Gallus domesticus) are the predominant poultry species kept under external systems in the rural and peri-urban poultry sector of Africa, which predispose them to various parasitic infections. The aim ...
-
Effect of ? carotene supplementation on oestrous synchronisation and milk production of Saanen goats (University of Pretoria, 2016)Goats play a major role in the life of rural populations, especially in the Sub-Sahara Africa. The use of nutritional supplements such as ?-carotene and the reproductive management techniques can lead to improved goat ...
-
(University of Pretoria, 2016)Protein, iron and zinc deficiencies are among the most prevalent nutritional deficiencies among children under the age of five years living in developing countries. Nutritional deficiencies are caused by insufficient dietary ...
-
(University of Pretoria, 2015)Rainfall variability in and between seasons, lower soil organic matter content, land degradation, and the associated low biomass yield and poor quality of forage are major constraints to livestock production in the subtropical ...
