Scientifically proven products to grow stronger birds from the inside out.

Get Flock Changing Results!
Frustrated with poor performance?

When sick birds, high feed conversion, low weights and wet floors persist no matter how much you disinfect, treat or supplement, it can make a farmer feel hopeless.


A day with no dead birds. Ranking number one. High weights, low feed conversion.

These don’t have to be daydreams. This has become a reality for thousands of broiler farmers we work with across the nation—and it’s possible for you too.

Scientifically Proven Products

Better birds from the inside out.

Each Southland Organics product is designed to strengthen your birds and their environment.

Our specially formulated supplements use biologically active, organic carbon and beneficial bacteria (probiotics) to strengthen nature’s defenses inside birds guts and in the litter below their feet.
This helps them fight off bad bacteria that cause disease like dermatitis, enteritis and so much more. It also helps boost their natural ability to absorb and process nutrients. This creates a healthier bird on every level. 

We believe so much in their effectiveness because science backs it up.

We put Big ole Bird, our poultry supplement and probiotic, to the test with two, third-party performance studies done by poultry science programs we knew farmers could trust—the Southern Poultry Research Group and the University of Georgia Poultry Diagnostic and Research Center.

These results translate into real cost savings and profit boosts for you.

Our Broiler Products

“I used Litter Life for the first time on this flock. I was amazed at the difference in ammonia, even after windrowing. I noticed the floors stayed drier through the 1st couple of weeks, saw better weight gains and better paw quality. All my farms averaged in the 9.80s to 10 lb at 60 to 61 days. That was using Big ole Bird, also.”

"I just wanted you to know I REALLY like the Mother Load. I don't know how I will finish, but I’m off to a great start. Floors pretty dry, good mortality and water consumption increasing every day. Great compliment to Big ole Bird in my opinion."
