There is a mistaken belief that Salmonella is transmitted to people primarily through dirty egg shells when, in fact, most cases of the illness are the result of an egg that was infected with Salmonella inside the hen's ovary. Most cases of the illness are the result of an egg yolk that was infected with Salmonella inside the hen's ovary. Probiotics given to baby chicks reduces the risk of Salmonella in eggs and disease later in life.
WHAT ARE PROBIOTICS?
Probiotics are live, nonpathogenic bacteria that contribute to the health and balance of the intestinal tract. These good bacteria can strengthen the immune system and help chickens digest food more efficiently, helping them stay healthy and grow better.
Most of us are familiar with the benefits that bacterial cultures in yogurt contribute to our own digestive health and some chicken-keepers give yogurt to their chickens to impart those same benefits. What many chicken-keepers do not know is that chickens are not equipped to digest dairy foods and would be better served by skipping the yogurt and ingesting the beneficial cultures (probiotics) alone.
Last year, I asked Dr. Rob McCoy, PhD, vice president of Manna Pro Poultry Nutrition his opinion about feeding chickens dairy and he indicated that birds do not possess the enzymes necessary to properly digest milk sugars. Considering the fact that mother birds do not nurse their young, it makes perfect sense. Feeding chickens a little yogurt occasionally is fine, but too much dairy can cause digestive upset and diarrhea. A better choice would be to give chickens probiotics specially formulated for them. A University of Guelph professor and an Agriculture and Agri-Food Canada food researcher have found that giving chickens probiotics stimulates their immune system and reduces the Salmonella bacteria in their gut by more than 99 percent.
The Inside Story About Salmonella Transmission: Egg Yolk Russian Roulette
In the commercial poultry industry, “stringent procedures for cleaning and inspecting eggs were implemented in the 1970s (which) made illness from Salmonella caused by chicken feces on the outside of egg shells extremely rare. However, unlike Salmonella infections from eggs in past decades, the epidemic that started in the 1980s and continues to cause illnesses today is due to SE (Salmonella enteritidis) being inside intact eggs with clean shells. The reason is that SE can silently infect the ovaries of healthy appearing hens and contaminate the inside eggs before the shells are formed. (A)n infected hen can lay many normal eggs while only occasionally laying eggs contaminated with SE. Chickens raised for meat can also be contaminated with SE.” source
A research team with the University of Arkansas studying the effects of probiotics on young chicks has found that giving probiotics to newly hatched chicks helps to keep them from developing and passing on diseases in later life, including Salmonella Enteritis.This information is significant, particularly for backyard chicken-keepers- providing backyard chickens with probiotics as soon as possible in life gives them the best chance to live a healthy, productive life, staving off illness and bacteria, including Salmonella.
Big Ole Bird (aka: BoB) Organic probiotics liquid. Mix 1 teaspoon to one gallon of water for 3 days, then take 2 weeks off, 3 days on, 2 weeks off.
BoB contains humates & fulvic acid, which impart health benefits to chickens in addition to the probiotic benefits! Read all about the BoB difference here.
What can probiotics do for laying hens?
- increase egg production, egg size & egg quality
- improve eggshell quality
- improve feed conversion
- keep bad bacteria at bay (acidifies the gut, reduces pH, competes with bad bacteria, elbowing it out, aka: competitive exclusion)
- improve absorption of nutrients in feed, decreasing feed costs
- stimulate the immune system, reduce the need for antibiotic use
Gro2Max probiotics: a 3.5 oz packet will make 28 gallons of solution. Use 1.5 teaspoons per gallon. Once opened, the package is good for 15-20 days.
Advantages of Probiotics
- 100% all-natural, organic & environmentally safe
- Safe and recommended for use in chicks
- No egg withdrawal period
- Can be used in traditional watering containers or poultry nipple watering systems (use a tea infuser or cheesecloth for dried, reconstituted probiotics)
- Can be used with chickens, ducks and geese
All of the data and research I have read supports the premise that probiotics are good for chickens in many ways and I feel strongly about adding it to my chickens’ waterers as soon as the day they hatch. If reducing the risk of Salmonella were the only benefit imparted by use of probiotics, that would be enough for me, but that there are so many other, proven benefits to my chickens and their eggs is what makes me so enthusiastic about recommending them. I encourage you to do your own research and draw your own conclusions. I have provided my sources and links for your reference.
