Abstract
Animal husbandry practices like sheep and goat rearing offer many advantages for
beginners and also experienced farmers. They are well suited and productive for the
prevailing agro-climatic conditions in India. In mammals, health status is governed by the
organ of lymphatic system. Though spleen is the secondary lymphatic organ, it is the
largest among the lymphoid organs which plays a crucial role in immune function. For the
present study, splenic tissue from adult sheep and goat (6 Nos. each) were collected from
Corporation slaughter house, Chennai. Gross, microscopic and immunohistochemical
observations were done. Micrometric observations of various structures were also
recorded. The spleen of sheep was triangular, whereas, in goat it was roughly quadrangular
in outline. In both the species, parenchyma was covered by a thick capsule, predominantly
made up of collagen, elastic and smooth muscle fibres. Thickness of capsule in sheep was
150±10.33μ and in goat it was 141±11.5μ. Trabeculae originated from inner side of the
capsule and extended in to parenchyma in both the species. Parenchyma was made up of
white pulp and red pulp and the proportion of these were almost equal. The white pulp was
composed of splenic nodule and peri-arterial lymphatic sheath. Red pulp was compost of
irregular splenic cords separated by splenic sinusoids. Immunohistochemical localization
of T-lymphocytes revealed the distribution of T-lymphocytes around the PALS and also
scattered in the red pulp.
