Probiotics and prebiotics in poultry nutrition
Under normal circumstances, there is a delicate balance of beneficial and pathogenic bacteria in the gastrointestinal tract (GIT). This is influenced by symbiotic and competitive interactions and relationships. The microbial communities will not only protect the GIT but also enhance productivity in the host. The use of probiotics and prebiotics are two approaches that have been examined and can potentially reduce enteric diseases in poultry and also enhance their productivity. These substances have been proposed to assist in the prevention of carcass contamination and improve the immune response in the chicken. Probiotics have been defined as 'a live microbial feed supplement which beneficially affects the host animal by improving its intestinal balance' (Fuller, 1989). The probiotic mode of action is by 'competitive exclusion', meaning there is competition for attachment sites in the GIT.
Abstract To study the ameliorative impact of mannan oligosaccharide (MOS) and sodium butyrate (NaB) during simultaneous aflatoxicosis and ochratoxicosis on carcass traits and organ weights, day-old broiler chicks (n=320) were divided into 10 treatment groups (T0: control; T1: T0+300 ppb aflatoxin B1 (AFB1)+250 ppb ochratoxin A (OTA); T2: T1+0.15% MOS; T3: T1+0.3% MOS; T4: T1+500 mg/kg NaB; T5: T1+1000 mg/kg NaB; T6: T1+0.15% MOS+500 mg/kg NaB; T7: T1+0.15% MOS+1000 mg/kg NaB;...

Introduction The use of antibiotic based growth promoters is presently facing serious problem and has raised global concern as some reports revealed their ill effects among which are development of microbial resistance to the products and their potential harmful effects on human health (Rahmatnejad et al., 2009). Moreover, antibiotics lead to drug resistance in bacteria and drug residues in meat (Issa and Omer, 2012). These shortcomings lead to the search for alternative...

1. Introduction Xylans, also known as arabinoxylans (AX) and pentosans, are the most abundant hemicelluloses in the cell walls of monocotyledonous plants, such as cereals. The presence of these polysaccharides has a direct negative impact on energy availability of monogastric diets (Choct and Annison, 1990), largely due to the direct effect of soluble AX on increasing digesta viscosity. These negative effects can be combatted by supplementing the diet with endo-b1,...

ABSTRACT The associated efficacy of Saccharomyces cerevisiae and vitamin E, in ameliorating ochratoxicosis was investigated in broiler chickens. Day-old broiler chicks (320) were divided into 8 treatment groups, viz. T1 (control; basal diet); T2 (T1 + 150 ppb OTA); T3 (T2 + 0.05% SC + 100 mg vitamin E-VE); T4 (T2 + 0.075% SC + 100 mg VE); T5 (T2 + 0.1% SC + 100 mg VE); T6 (T2 + 0.05% SC + 200 mg VE); T7 (T2 + 0.075% SC + 200 mg VE) and T8 (T2 + 0.1% SC + 200 mg VE/kg diet). Each...

Germination is the process by which dormant spores from bacteria become active and develop. Once germinated, the Bacillus organism can grow, produce metabolites and be of benefit to the gut health and performance of poultry. Germination is essential for the full expression a probiotic’s potential. Are you sure that your probiotic germinates inside your bird? With Alterion®, you can be...

INTRODUCTION
For many years, broiler intestinal health was supported by the widespread use of antimicrobial growth promoters (AGPs). These AGPs are antibiotic substances that were added to the feed at subtherapeutic levels, leading to improved animal performance. In the European Union, the use of AGPs was banned in 2006 while the Center for Veterinary Medicine of the US Food and Drug.

A number of cereals and other crops that are incorporated into the human and animal feed are susceptible to fungal attack and mycotoxin production, either in the field (before and after harvest) or during storage, transport, processing and feeding whenever conditions are favourable. The fungi involved produce highly toxic compounds as secondary metabolites referred to as mycotoxins, which can cause a variety of ill effects in humans and animals, from allergic responses to immunosuppression...
