Abstract
The current investigation was carried out on the seminal glands of six apparently healthy mature male Buffalo bulls and six immature. The specimens were collected and examined anatomically and histologically after being fixed in 10% buffered neutral formalin. The specimens were subjected to processing till paraffin sections were obtained and stained. The anatomical and histological findings of the seminal glands are varying with age. Anatomically, the immature seminal gland was small sized, flaccid in texture, white in color and measured about 0.80-0.95 gm in weight, 1.95-2.50 cm in length, 1.00-1.15 cm in width and about 0.46-0.60 cm in thickness. Meanwhile, in mature one became larger in size, firm in texture, pale yellow in color, multi-lobulated where had a very large lobules on its outer surface giving, cluster of grapes liked appearance. It measured about 7-8 gm in weight, 5-6 cm in length, 2-2.5 cm in width and about .80-1.3 cm in thickness. Microscopically, the seminal gland was observed consisting of a stroma of connective tissue and a parenchyma of differentiating and undifferentiating acini in immature animal. Meanwhile, in mature one, the parenchyma was consisted of secretory end pieces and well-developed duct system. With advancement of age, the thickness of the capsule and trabeculae increased, also the number of secretory end pieces per unite area increased and the amount of inter-glandular connective tissue stroma reduced.

The immature seminal glands were a pair of glands, present on the dorsal aspect of the pelvic urethra near the neck of the urinary bladder (Figure 1)
The seminal gland was composed of two main parts; stroma and parenchyma
Summary
The water buffaloes among the large animals play an important role in agriculture and have great economic and productive importance They are considered the main milk, meat and hide producing animals. They have the ability to convert the poor quality roughages into rich human foods, which is attributed to the features of its digestive system. The seminal gland is one of the most important male accessory genital glands in the body It play an important role in semen quality as it contains fructose and citric acid and spermatozoa- activating substances such as proteins, enzymes, mucus, vitamin C , flavin, riboflavin, sorbitol, inositol, ascorbic acid, prostaglandin, phosphoryle choline, ergothionin which are the vital components of the semen [2,3,4]. The high fructose concentration provides nutrient and energy for the sperm motility [5,6]
