Dietary modulation of gut microflora in broiler chickens: a review of the role of six kinds of alternatives to in-feed antibiotics (2009, background): “Bedford (2000) pointed out that the growth-promoting effects of antibiotics in animal diets are clearly related to the gut microflora because they exert no benefits on the performance of germ-free (GF) animals.”
Necrotic enteritis; a continuing challenge for the poultry industry (2006, background): “In the main, the addition of these enzymes reduces the viscosity of the digesta and as such should offer some protection against clostridial adhesion and thus disease outbreaks (Elwinger and Teglof, 1991; Bedford, 2000).”
Clostridium perfringens in poultry: an emerging threat for animal and public health (2004, background): “In Europe, antimicrobial growth promoters, used to increase weight gain in broiler chickens, will be banned from poultry feed due to the risk of spreading of antibiotic resistance (Bedford, 2000).”
Evaluation of cinnamon and garlic as antibiotic growth promoter substitutions on performance, immune responses, serum biochemical and haematological parameters in broiler chicks (2011, background): “Beker et al. (2003) demonstrated that as atmosphericO2decreases, growth rate is retardeddue to a depression in feed consumption.”
Potential strategies for controlling necrotic enteritis in broiler chickens in post-antibiotic era (2006, background): “The increased microbial activity in the caeca is a likely result of poorly absorbed products of enzymatic degradation entering the caeca, where they stimulate bacterial fermentation (Bedford, 2000).”
History of the use of antibiotic as growth promoters in European poultry feeds. (2007, background): “Moreover, safer nonantimicrobial substances have been studied as alternatives for replacing antibiotics to interact with the intestinal microflora, including enzymes ( Bedford, 2000; Hruby and Cowieson, 2006), prebiotics, and probiotics (Patterson and Burkholder, 2003; Kocher, 2006), or acidificati”
Effect of Formic Acid and Plant Extracts on Growth, Nutrient Digestibility, Intestine Mucosa Morphology, and Meat Yield of Broilers (2007, background): “demic cage trials, for example, where the microbiological stresses on the animal would presumably be unrepresentative of those encountered under normal commercial conditions [31].”
The Feasibility of Using Nutritional Modifications to Replace Drugs in Poultry Feeds (2002, background): “Bedford [82] proposed that proliferation of Clostridium perfringens and development of NE is facilitated by the appearance of large quantities of dietary protein in the ceca.”
Performance, immunity, serum biochemical and hematological parameters in broiler chicks fed dietary thyme as alternative for an antibiotic growth promoter (2010, positive): “A more balanced biota population in gut could lead to a greater efficiency in digestibility and utilization of food, resulting in an enhanced growth and improved FCR (Bedford, 2000).”
Thyroid Activity, Some Blood Constituents, Organs Morphology and Performance of Broiler Chicks Fed Supplemental Organic Acids (2008, background): “approved by Boling et al. (2001). Also, Abdo (2004) Additionally, the lowest levels were recorded in chicks observed an increase in blood calcium of broiler chicks received either AC (1.”
Feed additives to control Salmonella in poultry (2002, background): “Most antibiotic growth promoters act by modifying the intestinal flora, especially targeting Gram-positive bacteria, which are 502 World‘s Poultry Science Journal, Vol. 58, December 2002 associated with poorer health and performance of the animal (Bedford, 2000).”
The Effect of Probiotic and Prebiotic Feed Supplementation on Chicken Health and Gut Microflora: A Review (2012, background): “The increased microbial activity in the caeca is likely a result of poorly absorbed products of enzymatic degradation entering the caeca where they stimulate bacterial fermentation (Bedford, 2000).”
Combined effects of exogenous enzymes and probiotic on Nile tilapia (Oreochromis niloticus) growth, intestinal morphology and microbiome (2016, background): “302 Furthermore, xylanase may increase the digestion of NSPs (e.g. arabinoxylans) which could 303 provide substrates for utilisation by gut bacteria (Bedford, 2000).”
Isolation and characterization of a bacteriocin produced by an isolated Bacillus subtilis LFB112 that exhibits antimicrobial activity against domestic animal pathogens (2009, background): “But the emergence of multidrugresistant pathogens and imposed restrictions on the use of antibiotic feed additives have intensified the search for novel possible alternatives (Bedford, 2000; Wierup, 2000; Diep and Nes, 2002; Gillor et al., 2005).”
Use of Organic Acids as a Model to Study the Impact of Gut Microflora on Nutrition and Metabolism (2002, background): “This reduction in microflora, and its consequences, may be the underlying mechanism for beneficial effects of antibiotics [41].”
Alternatives to antibiotics for maximizing growth performance and feed efficiency in poultry: a review (2017, background): “…performance that is a result of enzyme supplementation thus has been linked to an increase in the overall Alternatives to antibiotics and feed efficiency in poultry digestibility and availability of nutrients for absorption (Bedford, 2000; Verstegen and Williams, 2002; Rebolé et al ., 2010).”
