CHROMFLEX™ C: Summer - Ice the birds

CHROMFLEX™ C is a unique combination of chromium propionate and coated Vitamin C, which helps to combats ill effects of heat stress by modulating energy metabolism in birds.

What is heat stress in poultry production?

Heat stress is a condition in which birds find difficulty achieving the balance between body heat production and body heat loss. 

How does heat stress affect poultry?

The normal body temperature of a bird varies between 40 to 42°C. The ideal environmental temperature for chickens is 18 to 24°C. An increase in environmental temperature causes an increase in body temperature. If there is increase in environmental temperature, body temperature also rises. In order to maintain the same body temperature of 40 to 42°C, birds lose heat through radiation, convection, conduction and evaporation.

Since the bird’s skin doesn’t have sweat glands, heat loss mainly happens through evaporation by panting. In order to lose 1 ml of water, the bird uses 540 calories of energy, which results in significant drop in production and weight. High mortality, decreased feed intake, lower-than-expected body weight gain, poor feed efficiency, reduction in egg production and poor eggshell quality are common adverse effects of heat stress often seen in poultry layer bird.

Physiology of heat stress:

The endocrine mechanism of stress regulation starts with the stimulation of hypothalamus and release of Adrenocorticotropic hormone (ACTH) from the anterior pituitary. This causes an increase of adrenal cortical steroid secretions in the bird. Continuous stimulation to the adrenal cortex leads to chronically high levels of corticosteroid hormone. This hormone is responsible for the formation of glucose from body's reserve of carbohydrates, lipids and proteins. Corticosteroids hamper insulin production and make body cells insensitive to insulin, which results in high blood glucose levels. Corticosteroids contribute to many of the disease associated with long-term stress, such as cardiovascular and gastrointestinal disease, hypercholesterolemia, metabolic rearrangements and antibody suppression.

CHROMFLEX™ C is a unique combination of chromium propionate and coated Vitamin C, which helps to combats ill effects of heat stress by modulating energy metabolism of birds. CHROMFLEX™ C enhances immunity, growth rate, production and livability.

The combination of chromium and Vitamin C has been found to give significant improvement over individual ingredients on performance of poultry. Chromium and Vitamin C work synergistically to combat the ill effects of heat stress. Chromium is a part of Glucose Tolerance Factor (GTF), which helps to stimulate the insulin release leading to better utilization of blood glucose. Chromium also helps in Vitamin C transportation through RBC. Vitamin C acts as an antioxidant and prevents oxidative stress. It helps to reduce the secretion of stress-releasing hormone, cortisol. It also helps in chromium absorption.
