Phytogenics in poultry nutrition
Phytogenics, also known as phytobiotics, are natural bioactive compounds of botanical origin that are used as alternatives to antibiotic growth promoters (AGPs) and are added to feed to enhance animal performance. Although phytogenics encompass a wide variety of substances of biological origin, formulation, chemical characterization, and purity, they can be classified into four groups: (1) herbs (products obtained from flowering, woody, and nonperennial plants); (2) botanicals (whole or processed parts of a plant, such as roots, leaves, tree bark, and spices); (3) essential oils (hydro-distilled extracts of volatile plant compounds); and (4) oleoresins (anhydrous solvent-based extracts). These plant-derived products do not contain residues, are natural, and are less toxic than synthetic antibiotics or inorganic chemicals. Many are generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and can be used as feed additives in animal nutrition.
INTRODUCTION Benzoic acid provides an effective control against fungi, yeasts and bacteria (e.g. E.coli and Salmonella ). Essential oils can inhibit Clostridium perfringens and stimulate the secretion of endogenous digestive enzymes (e.g. amylase and lipase). A trial was performed to evaluate the effect of benzoic acid in combination with essential oils (thymol, eugenol and piperine) –feed...

INTRODUCTION Antibiotics are microbial metabolites produced by fungi and algae which have low molecule weight and can inhibit the growth of other microorganisms even in low concentrations (Nir and Ve-Senkoylu, 2000). While antibiotics have prevalently been used as growth promoters in animal nutrition, European Community has prohibited the use of antibiotics in animal nutrition as growth promoters from January 1, 2006 (Anonymous, 2005). As a...

CARVACROL and Phytogenic Feeds (PF)
Posted on June 4, 2013 by admin
Carcavrol has the distinct aroma of oregano. Oreganon oil consists of Carvacrol and Thymol in the main. Now apart from flavouring there is a lot of use of these and other essential oils in the feed industry as an alternative to antibiotics.
Restriction on the use of in-feed antibiotics in many countries has fuelled the interest in alternative products. A group of natural products known as phytogenics has been the focus...

Anticoccidial efficacy of ‘Coxynil” a herbal feed additive was tested against Einieria tenella in broilers, vs. a vs. Salinomycin. Body weight of birds challenged with E. tenella in Coxynil treated groups was higher as compared to Coxynil untreated & Salinomycin treated groups.. Oocyst out put, lesion score, HI titres against New Castle disease virus and T Cells were significantly higher in Coxynil supplemented groups. Examination of ceaca of the birds, revealed that the...

NEXT Enhance® 150 is a standardised combination of thymol and cinnamaldehyde, an active ingredient of cinnamon extract. This combination acts to optimise gut flora equilibrium in the broiler and breeder chicken, leading to better feed efficiency and growth for the animal. Continuing to understand the mechanisms behind the consistent benefits in animal trials, Carotenoid Technologies SA (CaroTech®) has worked exclusively with the Zootechnical Department at the University of Ljubljana in...

Chinese researchers are trying to convince poultry-, pig- and shrimp-farmers to replace antibiotics with traditional Chinese medicines to fight bacterial and viral infections.
Since the avian flu and Severe Acute Respiratory Syndrome hit Asia and damaged economies in the region, antibiotics have played a prominent role in the control of animal pathogens, said Jeffrey Tze-Fei Wong, director of the Applied Genomics Laboratory of Hong Kong University of Science and Technology. But continued...
