Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    GROSS AND HISTOMORPHOLOGICAL STUDY ON EYE BALL OF THE ADULT SURTI BUFFALO (Bubalus bubalis)
    (AAU, Anand, 2014) MALSAWMKIMA; VYAS, Y. L.
    The present study entitled "Gross and Histomorphological Study on Eye Bail of the adult Surti Buffalo (Bubalus bubalis)" was carried out at the Department of Veterinary Anatomy and Histology in collaboration with Department of Veterinary Surgery & Radiology and Department of Veterinary Pathology, College of Veterinary Science & A.H., Anand Agricultural University, Anand, Gujarat. For this study, 20 eye specimens (10 right and 10 left) of buffaloes were used for the sonoanatomy, gross and histomorphological evaluations. The echobiometrical, biometrical and micrometrical measurements of the different parameters of the eye ball including cornea, sclera, choroid, retina and lens were recorded with the help of the scientific weighing balance. Vernier callipers, graduated eye piece and ultrasound machine. The histological sections were stained with Haematoxylin and Eosin Stain for routine staining and Masson's trichrome stain and Periodic Acid Schiff s stain for special staining. The ultrasonography of eye balls showed that the eye balls were appeared as ovoid structures with anechoic contents such as aqueous humour, vitreous body and lens. The cornea, anterior and posterior lens capsule, iris, ciliary body and corpora nigra were appeared as echogenic structures. The overall echobiometrical mean values of the anterior chamber depth, the antero-posterior depth of the lens, the vitreous chamber depth and the antero-posterior depth of both sides of the eye balls were 0.325±0.005 cm, 1.045±0.005 cm, 1.635±0.005 cm and 3.135±0.005 cm respectively. The overall biometrical mean values of the weight, the antero-posterior axis, the horizontal axis and the vertical axis of both sides of the eye balls were 31.16±0.01 gm, 3.67±0.00 cm, 4.04±0.00 cm and 4.01±0.01 cm respectively. The sclera was a white tough membrane of the eye ball perforated by the optic nerve at the posterior part. Histologically, it can be subdivided into three layers such as (i) the episclera (ii) the sclera proper and (iii) lamina fusca. The overall micrometrical mean values of the thickness of the sclera at the periphery was 445.96±23.05 µm and at the center was 856.95±33.84 µm. Histologically, the choroid was found to be composed of four layers such as (i) Suprachoroid (ii) Large vessel layer (iii) Tapetum and (iv) Choriocapillary layer. The mean thickness of choroid at the center of the tunic was 76.55±3.72 µm whereas, it was 48.86±1.78µm at the peripheral section of the tunic. The ciliary body was composed of ciliary muscles, collagen fibers, blood vessels, melanocytes, fibroblasts and processes. The cornea was an elliptical transparent membrane and the anterior surface was convex while the posterior surface was concave. The overall biometrical mean values of the vertical diameter, the horizontal diameter and thickness of both sides of the cornea were 2.37±0.00 cm, 2.905±0.015 cm and 1.20±0.09 mm respectively. The histological structure of cornea was composed of four corneal layers. These were (i) Anterior epithelial layer (ii) Corneal stroma (iii) Descemet's membrane (iv) Endothelial layer. The overall micrometrical mean values of the thickness of the epithelial layer, number of the epithelial layers, thickness of stroma, thickness of Descemet's membrane, thickness of endothelium and total thickness of both the center and periphery of the cornea were 99.29±0.625 µm, 9.35±0.06, 662.45±4.86 µm, 18.705±0.08 µm, 5.015±1.83 µm and 794.05±4.92 µm respectively. The histological structure of retina was composed of ten layers such as (i) Pigmented epithelium (ii) Layer of rods and cones (iii) External limiting membrane (iv) Outer nuclear layer (v) Outer plexiform layer (vi) Inner nuclear layer (vii) hiner plexiform layer (viii) Ganglion cell layer (ix) Nerve fibers layer (x) Internal limiting membrane. The thickness of the nerve fibers was greatly increased towards the optic disc. The nerve fibers were converged at the optic disc and passed through a sieve like structure of sclera, known as lamina cribrosa and then formed the optic nerve. The overall micrometrical mean values of the thickness of retina in the center of the tunic was 177.56±10.72 )µm and that of retina in the peripheral section of the tunic was 120.24±15.40nm. The lens was a transparent, soft and biconvex substance with the convexity more in the posterior surface than that of the anterior surface. The overall biometrical mean values of the weight, thickness and diameter of both sides of the lens were 2.525±0.005 gm, 1.32±0.00 cm and 1.845±0.005 cm respectively. Histologically, it was composed of three components namely (i) capsule, the outermost covering of the lens (ii) simple cuboidal epithelium and (iii) fibers, which formed the major portion of the lens. Almost all the biometrical observations of the eyeball including cornea and lens were non significantly lower in the right eye balls than that of the left eye balls and all the micrometrical observations of cornea were non significantly lower in the center than that of the periphery of cornea. However, the micrometrical observations of sclera, choroid and retina were non significantly lower in the periphery than that of the center of the tunics.
