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.

    CLINICAL STUDIES ON INTERDIGITAL HYPERPLASIA IN CATTLE
    (AAU, Anand, 2013) GOSAI, ROHITKUMAR K.; TANK, P. H.
    The present clinical work entitled "Clinical studies on interdigital hyperplasia in cattle" was carried out to evaluate clinical and epidemiological status of interdigital hyperplasia in cattle at different Panjarapoles and Gaushalas belonging to North Gujarat and Saurashtra region of the Gujarat State. A total 36 selected cases of interdigital hyperplasia in cattle were randomly allotted to three groups of 12 each, In Group-I conventional surgical excision was performed whereas, in Group-II and III animals were subjected to liquid nitrogen cryotherapy and thermocautery followed by conventional surgical excision, respectively. The relevant information was collected based on history, clinical symptoms, prevalence rate, breed, age, sex, methods of clinical management and rate of recurrence etc. and analyzed for defining the clinical status of interdigital hyperplasia in cattle. Different pathological stages of the interdigital hyperplasia in cattle recorded during the above clinical survey were documented. The pattern of its occurrence was categorized on the basis of etiology, location and degree of lameness to design the therapeutic and clinical and or surgical management of the malady. The overall incidence of interdigital hyperplasia was 0.49 per cent out of the total 8495 animals surveyed. The agewise incidence of interdigital hyperplasia in cattle was highest in animals between 10-12 years (1.20%). The highest occurrence of interdigital hyperplasia was found in Kankrej cattle (0.76%) followed by Gir (0.31%). The incidence of interdigital hyperplasia was higher in males (0.72%) than in females (0.17%). Majority of the cases of interdigital hyperplasia were seen in open yard with kachcha floor because of unhygienic conditions. The predisposing factors of interdigital hyperplasia in cattle were chronic irritation of interdigital skin due to poor hygienic condition, secondary bacterial infection and splayed claws. The occurrence of interdigital hyperplasia was higher (93.10%) in forelimbs than in hind limbs (6.89%). All the animals were kept off feed and water for 12 hours prior to anaesthetic induction and were given Inj. Benzathine penicillin 48 lakh lU i.m. and Inj. Melonex @ of 0.5mg/kg body weight i.m. 30 minutes before anaesthetic induction. After preoperative preparation, all the animals were restrained in lateral recumbency under mild sedation using Inj.Xylazine @0.01 mg per kg body weight i.v. Later on intravenous retrograde analgesia was achieved using 20 ml of 2% Lignocaine hydrochloride through radial vein in forelimb and tarsal vein in hind limb to provide adequate surgical anaesthesia. Fixing of wire loop at the tip of claws facilitated better exposure of lesion by widening the interdigital space and thus ease of surgical procedure in all the three groups. In conventional surgical excision, after surgical excision of fibrous mass profuse bleeding was noticed and controlled by applying pressure bandage and soaking of the bandage with tincture of benzoin. While, in liquid nitrogen cryotherapy after surgical excision bleeding was controlled by overlapping freezing followed by autothawing, whereas, in thermocautery after surgical excision. Cauterization of wound surface using hot firing irons was effective to control the bleeding and was found more efficient as it expedited healing without any recurrence. In all the three groups, interdigital space could be reduced by tightening of the claw wires, which additionally compressed the site and reduced the bleeding. The toe wiring was found dislodged on 2nd, 3rd and 4th week in some of the animals, during the postoperative observations. Histopathological examination of the interdigital growth showed classical features of fibroma characterized by excessive hyperkeratosis, capillarization, aggregation of lymphocytes around the capillary and epidermal thickening. In group-Ill animals, the time required for wound healing was significantly (p< 0.05) lesser than Groups-I and II animals. The bleeding was observed in three of the cases of group-I animals, whereas, in the group-II and III animals, there was no bleeding during the postoperative observations. Four animals showed mild degree of lameness up to six postoperative weeks which included 2 cases of Group-I, one case each of Groups-II and III. The rate of recurrence was 5.55% in Group-I animals, while Groups-II and III animals did not show any recurrence.
