Age Related Structural Changes in the Bulbourethral Gland of Gaddi Goat (Capra hircus)
A study was conducted on the bulbourethral glands of 30 Gaddi goats, divided into three groups of 10 animals in each viz; Prepubertal (1 day old to < 18 months of age), Pubertal (18 months to < 5yrs of age) and Postpubertal (>5yrs of age). The study revealed that the glands grew at a faster speed up-to 6 months of postnatal life after which the pace slowed down considerably. Almost 10 times increase in weight and more than three times increase in all the linear mensurations were observed in prepubertal group from the time of birth. The stroma vs parenchyma ratio which was 80:20 in one-day-old kids showed three times increase in parenchyma in prepubertal animals, and the ratio became 43:57. In one day old kids luminated and non-luminated secretory end pieces were arranged in small groups around widely luminated duct; the forerunner of the central cistern. Initially the gland contained serous as well mucous end pieces; the latter being more preponderant. But in pubertal animals it became a mucous type gland, with only a little numbers of serous end pieces. Histochemically, the glandular acini were reactive to PAS and Alcian blue indicated the presence of glycol-muco-complex in the secretory components of gland.
