Performance parameters and oxidation of body lipids of broiler chickens were investigated when their diet was supplemented with a commercial preparation of essential oils (Apacox) derived from selected herbs. One hundred and twenty day-old Cobb-500 female chicks were divided into…
Four hundred and eighty 54-week old Nick-Brown hens were assigned to four dietary treatments. Each treatment consisted of four replications of 10 cages (three hens per cage). The experimental diets were: 4.5 g available phosphorus (aP)/kg without phytase (control); 4.5…
The body composition, carcass characteristics and retail cuts of 61 Dormers (21 rams and 40 ewes) and 35 South African Mutton Merinos (SAMM) (17 rams and 18 ewes) were determined. A range of carcass measurements was recorded. Since there was…
The study was conducted to compare the effects of two essential oils, fed individually or in combination, with alpha-tocopheryl acetate (alpha-TA) on performance parameters and lipid oxidation of broiler meat enriched with n-3 PUFAs. Seven hundred and twenty day-old Hubbard-JV…
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…
In two experiments, one carried in South Africa and the other in Western Australia, the duration of sperm storage and the fertile period following separation of sexes were investigated by egg break-out and by counting the sperm in the perivitelline…
Repeated records (n = 58,295) of Bonsmara cows were used to evaluate mature cow weight (CW), using random regression animal models (RRM). Cows (n = 11,847), age two to 11 years (AY), were weighed at weaning of their calves. Data…
The potential of the yeast component, mannanoligosaccharide (MOS) to ameliorate the effects of aflatoxicosis was examined in growing Japanese quail. The product was incorporated in the diet at 1 g/kg and was evaluated for its ability to reduce the deleterious…
Data obtained from the Friesian Horse Studbook of Southern Africa and Friesian Horse Breeders’ Society of South Africa were analyzed to describe and evaluate the population regarding inbreeding and morphological body measurements. Eight different body measurements (height at withers, height…
The aim of the present study was to investigate the effect of dietary supplementation with an essential oil mixture, a commercially available organic acid and a probiotic on growth performance and carcass yield of broilers. One thousand two hundred and…
In this study the possibilities of using the Ile de France x Akkaraman (G1) genotype (IDFAG1) in improving the growth performance and carcass characteristics of fat-tailed Karakas sheep raised in rural farm conditions in the Van Region of Eastern Anatolia,…
Dry matter (DM) degradation of Glycrrhiza glabra L, Arbutus andrachne, Juniperus communis, and Pistica lentiscus was determined using two different techniques: (i) the in vitro gas production and (ii) the in situ nylon bag degradability technique. Samples were incubated in…
Dispersion parameters for number of piglets born alive (NBA) were estimated using a random regression model (RRM). Two data sets of litter records from the Nemscak farm in Slovenia were used for analyses. The first dataset (DS1) included records from…
A study was conducted to assess the effects of varying storage temperature and relative humidity (RH) conditions, and feed preservatives (a mixture of Mold-Zap (a fungal inhibitor) and Banox E (an antioxidant)) on performance, visceral organ weight, serum biochemistry and…
The objective of this study was to determine the effects of conjugated linoleic acid (CLA) oil supplementation on the growth performance and lipid metabolism in geese and the fatty acid concentrations in their liver and muscle tissues. One hundred and…
This study was conducted to investigate the effects of probiotic and/or prebiotic supplementation on growth performance and serum IgG concentrations in broilers. One thousand two hundred one-day old Ross-308 broiler chicks of mixed sex were randomly divided into four treatment…
Hulless barley contains more digestible nutrients than do whole barleys due to a lower content of indigestible fibre, but also contains a higher concentration of ß-glucans. The chemical composition and apparent metabolisable energy (AME) of five cultivars (3, 7, 12,…
Genetic diversity in candidate genes for fitness and production traits was explored in three populations of dairy cattle. The study focused on adipokines, including leptin (LEP), tumor necrosis factor alpha (TNF), interleukin-8 (IL8) and interleukin-10 (IL10) as candidate genes. The…
A study was conducted to determine the effect of supplementing the diet of breeder hens with a short-chain fatty acid (SCFA) premix, containing 509 g fatty acid salts/kg of which 285 g were calcium butyrate, on their eggshell characteristics and…
Female fertility is increasingly gaining importance in national dairy cattle breeding objectives worldwide. In South Africa, there is no routine prediction of breeding values for reproductive performance in dairy cattle and selection is mainly focused on production traits. The objective…
