Breeder farms and hatchery as integrated operation

Good rearing management is the starting point for healthy, productive and profitable hatching egg production. Rearing management means all factors which influence the birds’ health and includes several factors such as house structure, climatic conditions (ventilation, temperature, litter condition), stocking density, feed and water supply, hygienic conditions as well as the qualification and knowledge of the stockman. These factors affect each other and can promote or inhibit the health condition of the flock. In aiming to achieve desired performance results, managers of breeder flocks should integrate good environment, husbandry, nutrition and disease control programs. The rearing management must be directed to satisfy the bird’s requirements, to promote the production and to prevent diseases. Any disturbance can cause stress, which will reduce the resistance of the birds, increase their susceptibility to infections and reduce their immune response to vaccines.
