The study investigated the effects of varying dietary calcium (Ca) levels and sources of oil on performance of broiler chickens. A total of 378 one-day-old birds were fed 6% palm oil (PO), soybean oil (SO) or linseed oil (LO) in…
A study was conducted to determine the effect of dietary inclusion of discarded cabbage (DC) on the intake and growth performance of lambs. Diets containing 0 (control, DC0), 100 g DC/kg (DC100), 150 g DC/kg (DC150) and 200 g DC/kg…
During a broiler breeder trial with 3200 Cobb 500 hens, the effects of lighting treatment after 20 weeks’ feed allocation and of feed form on the length of time taken to consume the daily allocation of feed were measured. Pullets…
Wet distillers grains with soluble (WDGS) were blended with whole maize plants on an as-fed basis at 0%, 20%, 30%, and 40% and ensiled in 3 L bottles to evaluate the silage fermentation characteristics and ensiling quality in a complete…
The experiment was conducted to investigate the effects of diets supplemented with glucose oxidase (GOD) on growth performance, serum parameters and faecal microflora of piglets. One hundred and twelve piglets (35 days old) were randomly assigned to two groups (four…
This study aims at examining the expression of genes on the mammary gland, corresponding to various levels of adaptation or acclimatization to environmental stress. The authors utilized 18 cows from three genetic groups, Holstein Brazil (HB), Gyr (GG) and Gyrolando…
This study was conducted to investigate the effects of ovary transportation in a semi-complex medium containing HEPES at different temperatures on the developmental competence and the quality of in vitro-produced embryos. The cattle ovaries were transported in normal saline (NS),…
It was hypothesized that maize steep liquor, which is high in crude protein, could replace soybean meal in supplementation strategies in lamb production systems. Therefore, the effects of replacing soybean meal with maize steep liquor at 0%, 33%, 66% and…
This study investigated the effects of replacing rapid-release nitrogen (N) from urea with a graded level of slow-release N (Optigen® II) source on intake, digestibility, rumen fermentation and microbial protein synthesis, when sheep were fed a poor-quality roughage diet. Five…
Infestation with gastrointestinal nematodes is probably among the most pervasive problems in small-stock production worldwide. Faecal worm egg count (FWEC) has been reported as an indirect measure of parasite resistance in livestock production. Environmental and genetic factors of FWEC were…
The objectives of the present study were to determine the organic matter digestibility (OMD), metabolizable energy (ME), antioxidant activity and total phenolic and flavonoid concentrations of stems and seeds of Juncus acutus. Stem and seed samples were collected from Hamsiloz…
The effects of organic acid, probiotic and a combination of the two on performance and gut morphology in broiler chickens were investigated. Two hundred and forty one-day-old Arbor Acre broiler chicks were randomly assigned to five dietary treatments with six…
The identification of genetic polymorphisms in the genes that play a crucial role in regulatiing growth and development of livestock enables us to evaluate the biological similarities and to acquire a better perspective of quantitative traits. The present study was…
Members of the Federation of Boxer Clubs in Southern Africa (FBCSA) have participated in official recording for many years. The aim of the study was to estimate genetic parameters and trends for pre-weaning survival and to assess inbreeding in the…
Wasted cladodes from the cactus pear (Opuntia ficus spp.) are an environmental nuisance, and alternative measures are required to utilize this product, such as utilizing it as a ruminant feedstuff. By simulating ruminal fermentation through in vitro gas production, the…
Increased public concern for animal welfare in the logistics chain has led to a rise in the scrutiny of the treatment of food animals. Factors affecting the status of welfare of slaughter animals begin at the farm and occur during…
The desire to reduce feeding costs in small-ruminant production systems has led to increased reliance on non-conventional locally available browse products as protein supplements. Browse products contain variable quantities of tannins, whose nutritional effects on the animal can be positive…
This study was conducted to evaluate the effects of different levels of buckwheat (Fagopyrum esculentum) alone or in combination with chitosan, in broiler diets, on the growth, feed intake and serum lipid profile of broilers. Starting as 10-day olds, 144…
A study was undertaken to evaluate the effects of Neoxyval (antimicrobial growth promoter (AGP)), TechnoMos (prebiotic), GalliPro (probiotic) and a mixture of TechnoMos and GalliPro (symbiotic) on growth performance, carcass yield, histomorphology and intestinal bacterial counts in broilers (0 d…
A number of fatty acids (FAs), such as omega-3, omega-6 and conjugated linoleic acid (CLA), which are present in the milk from dairy cows are considered essential FAs and beneficial nutrients for humans. The aim of the study was to…
