Growth Promoters for Poultry Animals: How do they work?

In the past few years, there has been a substantial growth in the poultry industry, thanks to several growth promoting strategies and appropriate disease preventive and control measures among the flocks. Growth promoters are substances that are used by farmers and livestock owners with the intent of promoting growth, boosting overall efficiency, improving feed conversion efficiency and improving the quality of produce. These growth promoters are added to poultry feed supplements or induced in the form of injection to increase poultry nutrition.

There are different types of growth promoters used in poultry feed supplements such as antibiotics, probiotics, prebiotics, exogenous enzymes, antioxidants, herbs, and more. Apart from boosting production and promoting general health of the birds, several growth promoters seem to enable modulation of the immunity system and come with stress relieving properties. Let us take a look at the different types of growth promoters and how they increase poultry nutrition:


Antibiotic Growth Promoters (AGP) involve the use of antibiotics in poultry feed to improve overall growth and feed conversion. AGPs help improve the flock’s performance and keeps their health in check. It promotes growth by reducing growth-suppressing metabolites caused by microbes. These growth promoters also increase amino acid levels in the gut, and reduces stress and mortality in birds.


These are live microbial feed supplements which are used for balancing the population of microbes in the intestines. It restrains the growth of disease producing microbes in the birds, prevents digestive problems, enables absorption of nutrients, improves feed intake, increases growth rate and body weight, boosts fertility, reduces stress, and performs various other functions to enhance growth.


Prebiotics beneficially affect the host by stimulating growth of harmless bacteria. It provides energy and other limited nutrients to the intestinal mucosa. Probiotics also work by hindering the colonization of pathogenic bacteria in the birds.

Phytogentic Feed Additives:

Also known as PFAs or botanicals, Phytogenic Feed Additives are added to animal diet to improve performance and productivity. Phytogenics include essential oils, spices and herbs. These have several benefits such as antioxidants, anti-inflammatory properties, digestion promoting properties and more.

Organic Acids:

These acidifiers help in lowering gut pH among the birds, which in turn reduces the presence of pathogenic organisms. In order to hinder the growth of intestinal bacteria, dietary acidification is necessary, which reduces the availability of toxic bacterial metabolites.

Vitamins and Minerals:

Vitamins and minerals are used for improving growth as well as feed utilization, which in turn helps in better production. They also help maintain gut health and boost immunity in birds. Certain vitamins also have the ability to reduce weight loss in birds caused due to heat stress.

One of the most effective growth promoters for poultry is Easygrow by Natural Remedies. It improves mortality and immunity in hens, enables weight gain, allows for better flock uniformity, controls stress, and restores nutritional balance.
