Feed additives for poultry Prepared by : Goran Rebwar

Feed additives ●Feed additives are non nutritive product used in minute quantities to improve ₋feed quality ₋nutrient utilization ₋growth performance ●feed additives can boost the results of quality feeds ●most of the feed additives improve gut health

Benefits of feed additives ●better nutrient absorption and utilization ●reduce the growth of intestinal pathogens ●improve production performance ●improve feed conversion efficiency ●reduce stress ●minimize the chances of disease ●provide the feed with better quality ●maximize profit

Feed additives for poultry ●growth promoters ●toxin binders ●antioxidants ●electrolytes ●emulsifiers ●feed preservatives ●pellet binders ●coccidiostates

Growth promoters 1.Antibiotic growth promoters 2.Natural growth promoters ●prebiotics ●probiotics ●symbiotic ●yeasts ●organic acids ●herbal growth promoters ●enzymes ●vitamins and minerals

Antibiotic growth promoters ●used in animal feed since 1940s ●antibiotic with low dose used to improve growth performance ●good for growth but many demerits i.e. − drug resistance − drug residues transfer to humans −transfer of drug resistant bacteria to human ●AGP are banned in poultry production

Some of AGP are ●Lincomycin ●Enramycin ●Avilamycin ●Amoxicillin ●colitis ●neomycin ●zinc bacitracin

Prebiotics,probiotics, symbiotic and yeast ●prebiotics are non – living substances which promotes the growth of probiotic ●prebiotics are the microbial culture which promote gut health through competitive exclusion ●prebiotics + probiotics = symbiotic ●commonly used yeast as growth promoter is saccharomyces cerevisiae

prebiotics Fructose oligosaccharide (FOS) Manna oligosaccharide(MOS) probiotics Lactobacillus plant arum Bacillus subtilize

Organic acids ●Organic acids positively affect gut of bird ●reduce pH of gut, pathogens and improve nutrient utilization ●organic acids that can be used in poultry are a. citric acid b. butyric acid c. formic acid d. propionic acid e. lactic acid f. tartaric acid g. malic acid h. fumaric acid

Herbal growth promoters ●Derived from spices, herbs and essential oils ●improve gut health and nutrient utilization a. turmeric b. black seed c. garlic d. ginger e. aloe Vera f. neem g. Fenugreek h. aniseed
