FEED ADDITIVES ,MOA, CLASSIFICATION AND USES IN RUMINANTS.

.

FEED ADDITIVES

A compound added to the ration for supply nutrients

Health and performance of animals To improve the level of production better Efficiency average daily gain

CONT ……

minimize the incidence of bloat Acidosis reduce liver abscesses control problems of foot rot control parasitic diseases

CLASSIFICATION

Nutritive feed additives Vitamins Minerals Amino acid

NON NUTRITION FEED ADDITIVES

Antibiotic Prebiotic Ionophore Chemobiotic

IMPORTANT GROWTH STIMULANTS

Enzymes Chemobiotic PH regulator Feed flavor Hormones Prebiotic Probiotic

ANTIBIOTICS

formation of bacterial cell causes the bursting of cell act on gram +ve and –ve bacteria

CONT..

Bacitracin Streptomycin Virginiamycin Flavomycin

IONOPHORES

transform the microbial fermentation increase the utilization of feed and gain Lasalocid and Monensin etc change the types of fatty acids increase capture of feed energy performance improves

PROBIOTICS

Opposite of antibiotics have a +ve effect on the host detoxify the harmful metabolites helpful in improving nutrient availability Use as milk replacers increase the growth of beneficial

microflora Decrease the growth of pathogenic

bacteria

OLIGOSACCHARIDES

Fermented in the intestine Nutrient source for lactic acid

producing bacteria Fermented by favorable bacteria Microbial number may be increased

YEAST CULTURES:

Progress the… feed efficiency Feed gain Health Increased DMI pH of rumen nutrient digestibility

USES OF FEED ADDITIVE

Greater milk production Increasing the protein and fat in milk Improve DMI Motivate VFA production Increase digestion Stabilize the rumen environment and

ph

CONT..

Improve growth Improve feed efficiency reduced heat stress

BUFFERS

combination of acid and salt Decrease the rate of acidosis E.g Potassium carbonate And Magnesium oxide

MOA OF NSP

influences on digesta viscosity also on the intestinal microflora located in the cell walls partial hydrolysis of pentosans and ß-

glucans

MOULD INHIBITORS

mixture of organic acids prevent the mould growth It inhibition the mould growth Use for preservation of feed compound avoidance of mycotoxin growth it have lengthy feed storage time

CATEGORIES OF FEED ADDITIVE

Acids  Acidity regulators  Antifoaming agents  Antioxidants  Bulking agents  Emulsifiers 

CONT..

Flavors  Glazing agents Humectants  Preservatives  Stabilizers
