This study aimed to compare the effects of feeding 60 mg of the β-adrenergic agonist, zilpaterol HCl (Zilmax®), per steer per day versus feeding 120 mg of the β-adrenergic agonist, R-salbutamol (Salbutamate®10%), per steer per day for the last 30…
Six hundred one-day-old broiler chicks were used to determine the effects of Moringa oleifera leaf meal (MOLM), a probiotic, and an organic acid on growth, weights of digestive organs, and meat quality. Starter, grower, and finisher diets were formulated to…
Naringin is a major flavanone derivate that has many important biological functions in animals. However, its effect on pigs is unknown. The aim of this study was to investigate the effect of naringin supplementation on performance, carcass traits, meat quality…
The aim of this study was to evaluate the effects of commercial toxin binders on growth performance, organ morphology, immunity and serum biochemistry in broilers. Dietary treatments consisted of the negative control (NC): experimental diet with aflatoxin B1 <20 parts…
The aim of this experiment was to decrease the rumen degradability rate of recycled poultry bedding (RPB) protein using pomegranate peel extract (PPE) as the tannin source. Furthermore, to study the effects of this processing method on nutrient digestibility, rumen…
The study was conducted to determine the effect of the probiotics, Saccharomyces spp.Kb-5 and Saccharomyces spp.Kb-8, on growth performance, carcass characteristics, serum and meat cholesterol levels in ducks. Two hundred and forty 1-day-old healthy male ducks were randomly allocated to…
The aim of this study was to evaluate the effects of cross-breeding Turkish indigenous Morkaraman (M) ewes with prolific Romanov (R) rams on the reproduction and performance traits, growth traits, slaughter and carcass characteristics of the crossbred offspring under semi-intensive…
This experiment was conducted to determine the effects of pineapple stem by-product silage as a feed source in total replacement of Napier or corn silages on growth performance, feed intake and feed efficiency, ruminal fermentation, carcass characteristics and meat quality…
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 objective of the study was to determine the meat quality responses of weaner steers fed diets containing potassium humate (PH) in a feedlot. Twenty-two yearling male steers were randomly allocated to two treatments: control (n = 11), fed a…
In this study, performance and carcass characteristics of slow-growing broiler chicks, reared in organic or conventional systems, and fed a diet with an essential oil mixture (EOM, 48 mg/kg diet), were evaluated in the autumn and spring seasons. The rearing…
A study was conducted to evaluate the influence of feeding systems on carcass characteristics and composition of Mubende goats and their Boer goat crossbreds. A 2 x 3 factorial arrangement was used to randomly allocate 60 castrates, 30 purebred Mubende…
Megasphaera elsdenii (M.e.) NCIMB 41125 is a robust lactate utilizing strain of M.e. that is effective in minimizing the risk of ruminal acidosis in feedlot cattle. When dosed orally, cattle adapt smoothly to increasing concentrates in the diet, the incidence…
Six male and 24 female Pekin ducks per pen were randomly allocated to 12 pens to test the effects of quantitative feed restriction during the rearing period on subsequent reproductive performance. The feed treatments during the rearing periods were ad…
The aim of this study was to determine the effects of thyme (Thymus vulgaris L.), black seed (Nigella sativa L.) essential oils and flavomycin added to the diets on growth performance, carcass characteristics and intestinal organ weights of quails (Coturnix…
Growth, carcass characteristics and eating quality of meat from South African Mutton Merino wethers fed maize or different sorghum silage diets were studied. Forty newly weaned wethers (20 kg) were randomly allocated to 10 dietary treatments, viz. non-bird-resistant grain sorghum…
Malignant hyperthermia (MH) genotype, as expressed by the halothane genotype, was determined on a random sample of 100 pigs originating from the Western Cape. The pigs were slaughtered to investigate the effect of MH genotype on certain carcass characteristics and…
Animals, maintained from birth on a higher and lower fibre diet, were slaughtered when postnatal growth curves flattened off. Males tended to be larger than females. The meat of females tended to have higher lipid (9.2 g/100 g fresh mass)…
