Gross Morphological and Morphometrical Developmental Studies on Harderian Gland in Chicken

ABSTRACT

The present gross morphological and morphometrical study was conducted on the Harderian gland of chicken. A total of 32 numbers of healthy birds were procured from the Poultry Farm of Nagpur Veterinary College, MAFSU, Nagpur. The chicks were divided into 4 groups viz. 3, 10, 17, and 24 days of age with 8 chicks in each group. It was seen that the Harderian gland was found directed towards ventro-medial aspect of the eyeball in chicks and loosely attached by periorbital fascia to the underlying muscle. The average biometrical observations of left and right Harderian gland in respect of weight, length, width and area of gland were found increased with the advancement of age. Area of the gland increased on its length from 17th day to 24th day of age which resulted into more elongated glands
