Nutritional restriction of the growth rate of broiler breeder replacement pullets.
(1971)No abstract available. -
Performance of Hereford and Holstein heifers on kikuyu pasture (Pennisetum clandestinum), using n-alkanes for determination of digestibility and dry matter intake.
(1995)Kikuyu pasture (Pennisetum clandestinum) is potentially the most important source of roughage used to feed dairy heifers in summer in KwaZulu-Natal. It is commonly believed that on kikuyu pasture beef breed females ... -
The use of the N-alkane technique for measuring herbage dry matter intake in horses.
(1995)The use of n-alkanes as indigestible markers for the estimation of herbage dry matter intake in grazing ruminants, is reported to have significant advantages over other markers used for this purpose (Dove and Mayes, ... -
The effect of different methods of controlling urolithiasis on ovine mineral metabolism.
(1995)The widespread use of high-energy, low roughage diets among feedlot sheep has lead to the development of several production diseases (Bide et al., 1973). One of the least easily identifiable is urolithiasis, yet it is ... -
The long and short term effects of Leucaena leucocephala on ram fertility.
(2000)No abstract available. -
The evaluation of the growth parameters of six South African commercial crossbred pig genotypes.
(2002)Simulation modeling is an active part of animal nutrition. These complex programs rely on mathematical functions to predict the performance of an animal. The Gompertz equation is a simple, but accurate function that fits ... -
Family poultry studies in KwaZulu-Natal.
(2002)This work was in two parts, the first part was an on-farm survey of family poultry production and the second study was on-station research which investigated the replacement of maize by bread waste in layer diets. The ... -
The effect of feed type and diet quality on kinetics of digestion : the degradation properties of certain protein supplements, and the effect of concentrate supplementation and basal roughage quality on eating behaviour and particle passage from the rumen of sheep.
(2002)The unique anatomical structure of the ruminant animals' digestive tract allows them to convert forages containing high levels of fibre into the valuable products of meat, milk and wool. At the same time, an interdependent ... -
Influence of composition and storage conditions on diet quality and productivity of broiler chickens.
(2003)Two experiments were conducted to assess the effects of varying storage temperature and relative humidity (RH) on feed quality and nutritive value of such diets when fed to broiler chickens. The diets used in experiment ... -
Effect of urea-ammoniation of dietary roughage and concentrate ratio on ruminal microbial activity in Jersey cows.
(2003)The effect of untreated roughages on digestibility and rumen fill of the gut was reviewed as physical mechanism influencing the regulation of roughage intake. The review of literature also focused on identifying factors ... -
Dairy constraint analysis in Eritrea, with special emphasis on Asmara and surrounding dairy farms.
(2003)The overall objective of the study reported in this thesis was to assess the existing situation of the dairy sub-sector in Eritrea with special emphasis on the Asmara and surrounding dairy farms. The specific objective ... -
Liver abscesses and performance in feedlot cattle as influenced by dietary roughage level and tylosin inclusion.
(2003)The focal interest of this study was the problem of liver abscesses that occurs in intensively fed beef cattle. The literature on metabolic disorders and diseases associated with feeding high concentrate diets to beef ... -
A production function analysis of fresh milk production in the highlands of Eritrea.
(2004)This study presents a production function analysis of fresh milk producers in the Highlands of Eritrea for the year 2002, dealing with the most important factors of production. Most dairy farmers are located in the Central ... -
The effect of dietary protein and energy on feed intake and performance of laying hens.
(2005)This study was designed to devise a method by which the optimum combination of dietary energy and protein could be found that maximises the margin over feeding cost in an egg production enterprise. It was necessary to ... -
Factors influencing the rates of lipid deposition and withdrawal in growing pigs.
(2005)This study was conducted to determine the influence of factors on the efficiency of protein utilization and the rate of lipid deposition and withdrawal in growing pigs. Two experiments were conducted in total. The first ... -
The effect of group size and floor-space allowance on the efficiency of lysine utilisation by growing pigs.
(2005)Two experiments were conducted for this thesis, to determine whether an animal should be fed to its genetic potential in spite of this not being achievable due to an on-farm constraint. The first experiment was designed ... -
Choice feeding as a method of meeting the changing protein requirements of broilers during their growing period.
(2005)Broiler production is an important animal production enterprise with potential to make high returns. Increasing feed efficiency and early body weight gain has always been a top priority in the broiler industry. The general ... -
Testing for passive transfer of immunity in foals, and an evaluation of the African horse sickness vaccination schedule.
(2005)This thesis comprises an introductory review of the literature, followed by reports of two experiments which are presented in the form of scientific papers. For this reason, there may be some repetition between chapters, ... -
Constraints on smallholder dairying in Swaziland : Manzini Region & surrounding areas.
(2005)Summary: Swaziland has long had a disparity between the supply and demand of milk. Even at present milk production continues to be less than the market demand. The quantitative contribution of smallholder dairy farmers ...
