Vitamins are very important in maintaining the health and functions of most living organisms. It is well known that vitamin deficiencies cause immune system disorders. Poultry vitamin requirements are usually determined under ideal breeding conditions. Because poultry are affected by various stresses in breeding halls, the need for vitamins to cope with stressors increases. The role of vitamins in improving bird performance during heat stress has long been studied. However, according to research, the amount of need for certain vitamins in heat stress conditions has not led to an absolute conclusion. Many poultry farmers not only use vitamin C during hot periods to prevent the harmful effects of heat on the emergence function, but also to improve the immune system, the quality of the final products produced, fertility and hatchability in flocks of broiler breeders. In poultry production, heat stress is defined as both acute and chronic. Acute heat stress refers to short and sudden, sudden periods of temperature rise, and chronic heat stress refers to long and slow periods of heat.
