_______________________________________________________________________________ Abstract Growth and carcass characteristics of three Ethiopian goat breeds, the Afar, Central Highland (CHG) and Long-eared Somali (LES) were evaluated using three grainless diets varying in concentrate:roughage ratios (diet 1 was 50:50, diet 2, 65:35 and diet 3, 80:20) under(More)
Recent ambiguity about the role of animal fat in causing coronary heart disease, coupled with the controversy regarding the effect of various levels of energy nutrition on ruminant depot fats, prompted an investigation into the influence of high-energy nutrition, breed and slaughter weight on the fatty acid profiles of ruminants. Two isonitrogenous and(More)
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 eight different genetic groups, two diets (14.4 and 16.2% crude protein) and(More)
Goat meat in human nutrition as a primary and supplementary nutrient source is presented in terms of the dist ribution of goats, production characteristics, composition and nutrient value of goat meat, muscle fat and processed goat meat. Man is a complex being living in a complex environment, under varyingdegrees of psychological and physical strain. The(More)
Halofuginone was administered to both sexes of 2 broiler strains, Ross and Hubbard, in 4 dietary treatments, 0, 1.5, 3 and 6mg kg-1. Controls received dietary monensin at 100 mg kg-1. Group feed intake and body mass were recorded weekly. Skin tensile strength was monitored on Days 28, 35, 42 and 49 using a standardised cut of breast skin from carcasses(More)
Models for fault diagnosis can help reduce the time taken to accurately identify faults, but the complexity of modern enterprise systems means that the process of manually model-building is itself very time-consuming. We study here the relevance of bootstrapping a diagnostic model that can then be manually refined and augmented by domain experts. We present(More)
Afrikaner bulls (n = 30) between 9,5 and 15 months old, were allocated to 2 dietary treatments fed ad libitum. Diet 1 consisted of 70% concentrate and 30% Eragrostis curvula hay (11,4 MJ ME kg-1 DM) and Diet 2 of 40% concentrate and 60% E. curvula hay (9,3 MJ ME kg-1 DM). Five libido tests were conducted per bull between the ages of 16 and 28 months. Bulls(More)
South African Mutton Merino wethers (n = 32) were slaughtered, yielding carcasses with a mean weight of 22·18 ± 2·11 kg. Sixteen carcasses were electrically stimulated (ES) (21 V, 60 Hz, 120 s) immediately and all carcasses were chilled at room temperature (16°C) for 3 h and then overnight at 4°C, 95% RH. Both left and right Mm. longissimus lumborum et(More)
Forty steers of medium maturity were allocated randomly to four treatment groups of 10 steers each (C = Control, βA = β-Agonist, TO = Trenbolone acetate + oestradiol-17β and βTO = β-Agonist in combination with trenbolone acetate + oestradiol-17β). After 56 days on treatment, the β-Agonist treatment was stopped and the steers slaughtered on the ninth day(More)
