Are your laying hens suffering from diarrhea and laying "fecal eggs"? You got the very first step wrong!

In modern, large-scale layer farming operations, maintaining peak egg production and ensuring the stability of egg quality are the core metrics by which a farm's profitability is measured.

In modern poultry farming, the condition of the flock's droppings serves as the most intuitive "barometer" for assessing their overall health. When inspecting their poultry houses, many farmers frequently observe that the droppings contain undigested feed particles, or that the excrement appears as hard, egg-shaped pellets with abnormal coloration—a phenomenon vividly referred to within the industry as "chickens passing egg-like droppings" (also known as the "undigested feed" phenomenon).


This not only signals a disruption in the flock's intestinal function but also directly leads to reduced feed conversion rates and a decline in egg-laying performance, thereby inflicting heavy economic losses upon poultry farms. As a leading global provider of poultry health solutions, AGOVEE is dedicated to resolving such challenges through scientifically grounded nutritional and pharmaceutical strategies. This article offers an in-depth analysis of the causes and symptoms associated with the excretion of eggs mixed with feces in chickens, along with expert recommendations for its prevention and control.

I. What is "Fecal Egg Syndrome" in Chickens, and What Are Its Harms?

Clinically, "Fecal Egg Syndrome"primarily manifests as the excretion of unformed feces containing visible fragments of yellow or white corn and soybean meal granules. Furthermore, the surface of the droppings is often coated with a layer of oily or mucous-like substance. In severe cases, the feces may dry and harden into spherical masses (resembling "fecal eggs"), or take on colors resembling those of tomatoes or carrots.The essence of this phenomenon lies in compromised intestinal health in laying hens. When the intestinal mucosa is damaged, peristalsis becomes excessively rapid, or enzyme secretion is insufficient, feed is expelled from the body without being fully digested. The detrimental effects of this condition are primarily manifested as follows:

Reduced Feed Efficiency: Significant quantities of nutrients are lost through feces, leading to a substantial decline in the feed conversion rate.

Fluctuations in Egg Production: Chronic passage of undigested feed particles in droppings leads to malnutrition in the flock, resulting in a decline in egg-laying rates and deterioration in eggshell quality (e.g., an increased incidence of rough-shelled or malformed eggs).

Compromised Immunity: The intestine serves as the largest immune organ in poultry; damage to the intestinal barrier can precipitate secondary infections, such as *E. coli* and *Salmonella* diseases.

II. Analysis of the Primary Causes of Chickens Passing "Egg-like" Droppings

The causes of "egg-like droppings" in chickens are complex and multifaceted, typically resulting from the interplay of various factors:

1. Pathological Factors: Invasion by Pathogenic Microorganisms

This is the most common underlying cause of this condition. Among these factors, coccidiosis and enterotoxemia syndrome are the primary culprits.

Intestinal Coccidia: Coccidia proliferate extensively within the intestinal mucosa, leading to mucosal hemorrhage and necrosis, thereby impairing nutrient absorption.

Necrotic Enteritis: Caused by *Clostridium perfringens*, this condition results in thickening or necrosis of the intestinal wall and the production of large quantities of toxins.

Viral Infections: Such as proventriculitis caused by adenoviruses, which leads to abnormal gastric acid secretion and disrupts the initial stages of digestion.

2. Physiological and Management Factors

Heat Stress: In high-temperature environments, excessive water intake by the flock accelerates intestinal peristalsis and reduces feed retention time, triggering the typical phenomenon of undigested feed passing through the digestive tract.

Poor Ventilation: Excessively high concentrations of ammonia and hydrogen sulfide within the poultry house stimulate a stress response in the birds, thereby inhibiting the activity of digestive enzymes.

3. Feed and Nutritional Factors

Mycotoxin Contamination: Mycotoxins present in the feed—such as vomitoxin and zearalenone—directly erode the intestinal mucosa of the birds, leading to a complete breakdown of digestive function.

Nutritional Imbalance: An excessively high crude fiber content in the feed, or poor protein quality, places an increased mechanical burden on the intestines, making the birds highly susceptible to passing undigested feed particles in their droppings.

IV. Comprehensive Prevention and Treatment: Safeguarding Intestinal Health at the Source

When addressing the issue of "egg-like droppings" in chickens, antibiotic-only treatment often merely addresses the symptoms without resolving the root cause. AGOVEE recommends adopting a comprehensive strategy that integrates husbandry, prevention, and treatment.

1. **Optimize Environmental Management**

Maintain a dry and well-ventilated poultry house, and regularly remove manure to minimize the irritation caused by harmful gases to the flock. During hot seasons, utilize evaporative cooling pads to lower temperatures and

prevent heat stress-induced intestinal disorders.

2. **Strictly Control Feed Quality**

Insist on using high-quality raw materials, and consistently incorporate the mycotoxin adsorbent developed by AGOVEE into the feed to block the harmful effects of toxic substances on the intestines at the source.

3. **Scientific Pharmaceutical Intervention**

When the flock exhibits distinct symptoms of "fecal-egg syndrome" (passing feces along with eggs), immediately administer targeted poultry medications.


Controlling Diarrhea and Hemorrhage: Select highly effective anticoccidial agents in combination with sulfonamides.

Mucosal Repair: The repair of the intestinal mucosa is the core of prevention and treatment.

IV. AGOVEE Core Solution: Building a Healthy, Resilient Gut

As an innovative pioneer in the industry, AGOVEE has launched a specialized product series for intestinal regulation and repair, specifically designed to address issues such as undigested feed in droppings and related malabsorption phenomena in chickens. Our solution demonstrates significant efficacy across the following three dimensions:

1. Potent Antibacterial Action and Repair

AGOVEE products are rich in plant-derived essential oils (such as GARLIFORCE allicin extract) and functional organic acids

These ingredients effectively inhibit the proliferation of harmful bacteria within the intestinal tract while simultaneously promoting the growth of intestinal villi.

 In practical field applications, the implementation of the AGOVEE regimen has resulted in a greater than 30% improvement in the prevention and control of enteritis within poultry flocks.

2. Enhanced Feed Conversion Ratio

Our products significantly boost the activity of endogenous enzymes in chickens (such as amylase and protease), 

thereby ensuring that the nutritional components within the feed are more thoroughly broken down within the intestinal tract. 

following the use of the AGOVEE synergizing series, poultry farmers have consistently reported the marked disappearance of undigested particles in droppings; 

the excreted manure exhibits a normal color and excellent consistency, signifying a qualitative leap in feed conversion efficiency.

3. Stabilized Egg Production Performance

By establishing a healthy balance in the intestinal microecology, AGOVEE enables poultry flocks to maintain stable nutrient absorption capabilities, 

even under stressful conditions. This is particularly crucial for flocks currently at their peak laying stage, 

as it effectively prevents fluctuations in egg production—often caused by digestive disturbances—while significantly boosting the laying rate and improving eggshell color.
