Vitamin D is the most important nutrient for the proper absorption of calcium. Vitamin D is produced through direct sunlight, or through diet. It can be supplement with Vitamin D supplements. Without Vitamin D birds can not digest anything properly. But that is not the end of it. Birds require sunlight for other reasons also and Vitamin D does not play any part in it.There sunlight is a must or a source of light near to sunlight. There is a gland that surrounds the bird’s eye, called Harderian Gland. It measures the duration of light – called the photoperiod – and passes the information along to the pineal gland. The pineal gland and the pituitary gland both act as regulators to the endocrine system, and therefore to the entire metabolism of the bird. There duration of sunlight plays a vital role in stimulating the breeding cycle.
