Advantages of light programs

  1. Improved feed conversion ratio
  2. Increased vitality
  3. Improved growth
  4. Decreased mortality associated with heart problems
  5. Reduced mortality at the end of breeding period and increased appetite that helps to avoid weight loss
  6. Reduced incidence of ascites
  7. Reduced cost of energy



Practical recommendations with light management

  1. Dark hours can be continuous or intermittent according to growing conditions and hen house management.
  2. A constant 24 hours light is recommended for the first three days of breeding period
  3. The time at which the daily darkness begins throughout the breeding period must strictly follow the time it was at the beginning of the perid
  4. When light programs are used to regulate growth, the adequacy of the feeder and drinker space must be ensured so that birds can have free access to appropriate diet and water.
  5. The appropriate light intensity is 20-30 luxes for the first 7 days and 5-10 luxes afterwards.
  6. The most convenient way to reduce light intensity in hen house is to use dimmer or to substitute light bulbs according to age of birds.
  7. Light bulbs must be always kept clean. Dusty bulbs can decrease severity and effectiveness of light by up to 70%. It is recommended to install bulbs at 2.2 to 2.5 meters from the ground with 3.5 meters of intervals.
  8. During dark hours, be aware of any light entrance through air inlet valves and vents into the salon.

ArazDamKabir, with the management of engineer Pouria Kabiran, was established based on numerous foundations and with the aim of providing novel services in production and distribution of poultry and animal feed.   


The main target of the company is to maintain the customer satisfaction and, with reliance on its valuable experiences, aims at provision of health and nutritional services to the society through sustainable production of animal and poultry meat. The term Araz as refered to “clean originality” and “profound”, believes in the principle that promotion, profitability and customer satisfaction are prerequisite for cleanness, honesty and possessing novel scientific achievements and facilities.  

 ArazDamKabir with the utilization of professional knowledge of modern diet formulation, modern machinery, highly experienced personnel, research and development unit to update its products, and convenient and useful communication methods with customers, is trying to ascertain its duty of generation of superior quality and also distinguished services to customers.

Regarding undeniable importance of poultry and animal nutrition, we have aimed at supplying very high quality feed material that leads to production of highly efficient products and ensures customer profitability and health of final consumers in food chain of the society.

Nutrient requirements of broiler chicks change during the course of breeding period and birds have specific requirements for nutrients and diet formulation in each phase. The double-stage concentrates of ArazDamKabir have been formulated according to the latest achievements in poultry nutrition science worldwide to meet specific requirements of broiler chicks in each breeding phase with economically justifiable prices. 

The single-phase Omega concentrate has been formulated using the latest findings in poultry nutrition to yield, once used along with suggested diet formulations, an elegant balance in energy, amino acids, vitamins and minerals.

The Omega concentrate has been developed regarding all problems and challenges facing broiler farms throughout the country to satisfy all aspects of farmers needs.

In various part of our country, poultry breeding units bear huge economic burden due to viral and bacterial infections, deviating a considerable part of agricultural fund towards confronting poultry diseases.

Therefore, poultry raised in Iran need additional nutrients to those recommended in breeding catalogue. If the extra nutrients are supplied, birds can effectively fight viral and bacterial diseases and thus economic impact of the diseases can be avoided. Supportive concentrates of ArazDamKabir has been produced with the aim of respiratory and digestive disease control and are available throughout the country. The ingredients and recommended usage of ArazDamKabir are according to the latest achievements in the medical and poultry nutrition sciences and it has been formulated under direct consultation and supervision of highly experienced veterinary and poultry nutrition academics. These ingredients and their role in the improvement of respiratory and digestive problem are presented bellow.  


Vitamin A

Following diseases or stress, bird’s immune system is severely compromised and if supplemental vitamin A is not considered birds become highly sensitive to vast majority of pathogens. Delivering vitamin A to birds through diet or drinking water may prevent the incidence of the diseases in this condition.

Vitamin E

Vitamin E plays a major role in maintaining a healthy and effective immune system via elevating phagocyte activity. Phagocytes are a group of immune cells that engorge and neutralize pathogenic bacteria. Considering its important role during times of disease exposure, vitamin E must be delivered to birds to help immune system functionality.

Vitamin C

Vitamin C is not synthesized in sufficient amounts in birds under stress. This vitamin increases hormonal and cellular response to infections and thus increases bird’s resistance to infections caused by E. Coli, mycobacterium avium, Newcastle and infectious diseases of bursa and marek’s disease. Through its anti-oxidative effects, vitamin E stabilizes leukocyte membrane, and if available in adequate amounts, increases phagocytosis activity of neutrophils leading to destruction of pathogens.   


Selenium deficiency in the diet limits production and efficiency of glutathione peroxidase enzyme. This condition leads to the production of lipid hydroperoxide in the cell and damage to cell membrane. Research has indicated that one strategy to promote resistance in the poultry exposed to influenza virus is to use supplemental selenium to increase its level in the diet. 


Zinc deficiency in the body causes reduced appetite, weight loss and disturbed vitamin A absorption. Also, Zinc has an important role in regeneration of damaged digestive tissues following diseases.


The main function of amino acids is the production of proteins in the body. Among all amino acids, threonine has the most important role in the synthesis of proteins required by the immune system and white blood cells. Thus, increasing dietary threonine levels at the times of diseases can increase immune system capacity and help fight the diseases.

Organic acids

Some organic acids like formic and propionic acid, along their decreasing effect on gastro-intestinal pH, penetrate through membrane of gram negative bacteria into the cell, liberate H+ into bacterial plasma and disturb anionic component of DNA synthesis. This will inhibit bacterial proliferation, decrease digestive problems and improve animal health and performance.
