The current study investigated the effects of sex and stocking density and their interaction on growth performance and carcass characteristics of broiler chickens in a semi-arid sub-tropical environment. A total of 1008 day-old Cobb Avian48 chicks, namely 462 males and…
The present study was conducted to find out the dietary effects of mannan-oligosaccharides (MOS) supplemented diets on the production performance of four close-bred flocks (CBFs) of Japanese quail (Coturnix coturnix japonica) breeders. A total of 960 twelve-week-old birds of four…
This study was conducted to investigate the effect of dietary fatty acids (FA) on the fertility and hatchability of laying hens at the end-of-lay period (69 - 77 weeks of age). Five isoenergetic (12.4 MJ ME/kg DM) and isonitrogenous (170…
A study was conducted to determine the effect of egg weight on hatchability, chick hatch-weight, mortality and subsequent productivity of indigenous Venda chickens. Three hundred and sixty indigenous Venda chicken eggs were collected for a period of a week and…
A study was conducted to evaluate the growth performance of indigenous and Rhode Island Red (RIR) chickens under intensive management conditions for 22 weeks using standard commercial diets. Eggs from seven indigenous chicken lines were collected from the respective administrative…
Production traits of chickens of the Lesotho line, namely: body weight, body weight gain, feed conversion ratio (FCR) and mortality, were compared with four South African indigenous lines (Ovambo, Potchefstroom Koekoek, Lebowa-Venda and Naked Neck) and two exotic lines (Rhode…
Saanen and South African Indigenous goats were crossbred, and all three types were compared in terms of productivity, milk production and diseases between 1988 and 1994. Clinical mastitis occurred in the herd at a moderate level (28 cases of clinical…
To overcome a lack of data on the use and acceptability of saline water for goats, a survey of saline water use by drought affected goat producers in Australia was completed. The responses (n = 31) from all but one…
The aim of this study was to investigate the effect of thermal conditioning of broiler chickens during embryonic development on subsequent performance under standard rearing conditions. During incubation eggs from 32-, 45- and 56-week old Ross 308 broiler parent stock…
The growth performance of 18 Holstein and 20 Jersey heifer calves fed calf starter meals containing either cottonseed oil-cake meal (CSOCM) or soybean oil-cake meal (SBOCM) was compared. The diets were iso-nutritious in terms of crude protein and energy, and…
Two experiments were conducted to determine the response in performance, including uniformity and mortality, of two broiler strains to dietary protein content. In Experiment 1, 480 Cobb 500 and 480 Ross 788 day-old sexed broiler chickens were housed in cages…
