It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country.

    PATHOLOGICAL STUDIES ON THE COMMONLY OCCURRING DISEASES IN BOVINE CALVES
    (CSKHPKV, Palampur, 2017-11-06) Mahajan, Shagun; Patil, R.D.
    The present study was conducted to determine the prevalence and the etiolpathology responsible for bovine calf mortality in Himachal Pradesh. A total of 41 nasal swabs and 185 faecal samples were collected from dead, clinically sick and non-clinical (healthy) animals. Necropsy of 30 calves (17 Males, 13 Females) of various age groups (< 1M, 1- 3M, 3-6M, 6-9M and 9-12M) was performed during August, 2015 to April, 2016. The pneumo-enteritis was the major cause of death in 63% of calves. Grossly,out of 30 calves, 8(26.6%), 8 (26.6%), 3 (10%) and 4 (13.3%) calves showed bronchopneumonia, interstitial pneumonia, pulmonary congestion and pulmonary congestion and edema respectively. However, 2(6.67 %) and 20 (66.7%) animals showed haemorrhagic enteritis and catarrhal enteritis respectively. Histopathologically, in bronchopneumonia cases, the bronchioles and the alveolar lumen were filled with polymorphonuclear cells. Staphylococcus aureus was isolated from the lungs showing sub-acute to chronic abscesses, whereas, in interstitial pneumonia thickening of inter-alveolar septa due to mononuclearcells infiltration, hyperplasia of the bronchial and bronchiolar epithelium with peribronchial and peribronchiolar lymphoid proliferation. Intestine revealed presence of macroschizonts and microschizonts of coccidian with infiltration of inflammatory cells. Shortening and fusion of villi, desquamation and sloughing of villi, apoptosis and necrosis with infiltration of inflammatory cells in mucosa and submucosa indicative of viral induced enteritis.The serotype (O7, 088 and O118) were isolated from necropsy cases and major parasite wasEimeriabovis(28 % in clinically sick, 17.55 % in healthy and 3.44 % in dead calves) followed by Strongyloides eggs (20.6 % in dead and 3.81% in healthycalves) and Neoascaris vitulorum (8%) in clinically sick calves. This is also suggestive that parasitism is also responsible for playing important role in calf mortality.Ciprofloxacin was found to be the most sensitive antibiotic followed by Gentamicin and Oxytetracycline was the most resistant drug. The present study revealed that pneumo-enteritis is the major cause of calf mortality with its peak occurrence at 6-9 months of age group.
