a study was carried out to evaluate the effects of r. coriaria l. and p. farcta extracts as alternatives to antibiotic growth promoters in broilers diet. a total of 300 one-day-old male ross 308 chicks were randomly allocated to four dietary treatments (five pen replicates, 15 birds per pen) for the 0- to 28-d period, and all data were analyzed in a randomized complete design. dietary treatment...

Recent studies have evaluated the impact of alternatives to antibiotic growth promoters (AGPs) such as phytogenic feed additives (PFAs) in vitro and in vivo. Zhou and colleagues studied the antibacterial properties of 30 herbs on pathogenic Gram-negative and positive bacteria (1). Thirteen of the 30 herbs exerted a significant effect against Escherichia coli ATCC 25922 (p < 0.01, n = 11 and p <...

Phytobiotics represent a wide range of bioactive compounds that can be extracted from various plant sources. In recent years, some interesting and novel applications of phytobiotics in the production and well– being of monogastric animals have emerged, and these aspects are reviewed in the present paper. Recent studies at the University of New England indicate that water–soluble carbohydrate ex...

Potassium diformate (Formi) is odorless, low-corrosive and easy to handle. The European Union (EU) has approved it as non-antibiotic growth promoter, for use in non ruminant feeds. Maximum inclusion level of potassium diformate is 1.8% as registered by the European authorities which can improve weight gain up to 14%. Potassium diformate contains the active ingredients free formic acid as well a...

This report will review the history of antibiotic growth promoter (AGP) use in the animal industry, concerns about development of antimicrobial resistance, and response in the European Union and United States to these concerns. A brief description of the history of legislation regarding feed use of antimicrobials in Denmark and the experience of animal producers following the 1998 ban will serv...

in this research, we investigated the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, immune response and blood cholesterol in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and replicated 4 times with 12 chicks per pen in a completely randomize design experiment in 6 wk. diet ...

Application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. Therefore, scientists are searching for alternatives to antibiotics nowadays. Medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. In this paper, the benefits of...
