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.

    The present study was carried out to know the mortality pattern, gross and microscopic lesions of the colisepticemia in broiler chicken along with molecular detection of LPAI and avian mycoplasma in colisepticemia affected flocks. The study comprised of farm wise and age wise outbreaks due to Escherichia coli infection, gross and histopathological lesions of different organs, isolation, identification, biochemical characterization, antibiogram profile and molecular detection of virulence associated genes of Escherichia coli. Further, molecular detection of LPAI (H9N2) by RT-PCR and avian mycoplasma (Mycoplasma gallisepticum and Mycoplasma synoviae) by PCR in broilers affected with colisepticemia. Studies on the farm wise and age wise outbreak of colisepticemia among thirty broiler farms having total population of 1,71,317 birds of second to fifth week of age showed an average mortality of 1.89 per cent ranging between 0.32 and 6.75 per cent. The age wise outbreaks of colisepticemia revealed mortality 1.65, 1.97, 2.21 and 1.71 per cent during second, third, fourth and fifth week of age respectively. The outbreaks were higher in number during third, fourth and fifth weeks being the susceptible age for colisepticemia.

    PATHO - EPIDEMIOLOGICAL AND MOLECULAR IDENTIFICATION OF CHICKEN ANAEMIA VIRUS IN BROILERS
    (Department of Veterinary Pathology College of Veterinary Science and Animal Husbandry Anand Agricultural University Anand, 2020) Kabariya Digjay Vasantbhai; Dr. C. J. Dave
    Chicken infectious anemia (CIA) is known to be an emerging, immunosuppressive and highly contagious disease that affects young broiler chickens from 3 weeks of age. The disease's causative agent is Chicken anaemia virus (CAV), which belongs to the genus Gyrovirus of Circoviridae family. In commercial broilers, there is a better need to diagnose the sub-clinical type of CIA in the field because it interferes with the development of an immune system that makes affected birds more vulnerable to variety of infectious. It is very important to detect subclinical infection of CIA in flock as it is a risk factor for a clinical outbreak in the next flock and it can also cause immunosuppression which can lead to substantial economic loss. The present study was carried out in broiler birds belonging to 25 commercial farms suspected for CIA. The broiler birds having 10 per cent or above variation in size was selected. The pathological study comprised of information related to age, clinical signs, mortality pattern, hematobiochemical studies and gross as well as microscopic lesions in organs like thymus, bursa, bone marrow, liver, spleen and lung of affected broilers. The molecular study comprised extraction of viral DNA from different tissue by PCR for detection of CAV and also for phoA gene of Escherichia coli.

    (Department of Veterinary Pathology College of Veterinary Science and Animal Husbandry Anand Agricultural University Anand, 2019) Sagar R. Surjagade; Dr. B. P. Joshi
    The present study was carried out to know the incidence, mortality pattern, gross and microscopic lesions of the E. coli infection in broiler chicken as well as to know the antibiogram profile and antibiotic resistance gene in E. coli. The study comprised of epidemiological information in relation to autopsy incidence and farm wise mortality, gross and histopathological examination of different organs, isolation, identification, biochemical characterization and molecular detection of E. coli. Further antibiogram profile and detection of antibiotic resistance genes of E. coli isolates were carried out.

    (Department of Veterinary Pathology College of Veterinary Science and Animal Husbandry Anand Agricultural University Anand, 2019) Prajapati Ramdatt K.; Dr. D. J. Ghodasara
    The present study was carried out to know the prevalence of subclinical coccidiosis and necrotic enteritis in broilers affected with different diseases / pathological conditions received for post-mortem examination. The study was carried out in 50 broiler flocks of 2-7 weeks age. The study comprised of direct smear examination, molecular detection and oocyst count (OPG) of subclinical coccidiosis and molecular detection of Clostridium perfringens.

    (DEPARTMENT OF VETERINARY PATHOLOGY COLLEGE OF VETERINARY SCIENCE AND ANIMAL HUSBANDRY ANAND AGRICULTURAL UNIVERSITY ANAND, 2017) Disha Y. Raval; Dr. D. J. Ghodasara
    The present research work was carried out to know the etiopathology of field outbreaks of inclusion body hepatitis and efficacy of commercial vaccines against serotype 4 and 11 of inclusion body hepatitis- hydropericardium syndrome (IBH-HPS) virus. The field study comprised of farm wise mortality, gross and histopathological lesions, molecular diagnosis of IBH-HPS virus and its serotyping. The experimental study comprised of vaccine efficacy study of three commercial vaccines against serotype 4 and 11 of Fowl Adenovirus. The field outbreaks of IBH-HPS were recorded in 22 commercial broiler farms situated around Anand in Gujarat State during January 2016 to December 2016. The mortality of IBH/HPS in these field outbreaks ranged from 0.63 per cent to 11.19 per cent with an overall mortality of 1.83 per cent. Gross lesions of IBH-HPS were mainly observed in the liver and heart. The liver of affected birds was enlarged, friable, pale, had mottled appearance with presence of necrotic foci. Heart showed hydropericardium with presence of moderate to severe accumulation of straw colored fluid in the pericardial sac. Microscopic lesions were most consistently seen in the liver and heart. The section of liver from affected birds showed multifocal area of necrosis, mononuclear cell infiltration in the hepatic parenchyma and presence of basophilic intranuclear inclusion body in the hepatocytes. Few birds also revealed presence of eosinophilic intranuclear inclusion body in the hepatocytes. Histopathological examination of heart revealed mononuclear cell infiltration, severe vascular changes, oedema and mild haemorrhages in myocardium.
