    (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.

    STUDIES ON CLINICO-PATHOLOGICAL AND IMMUNOMODULATORY EFFECTS OF COW URINE AND ITS SYNERGISTIC ACTION WITH AQUEOUS POLY HERBAL EXTRACT IN COMMERCIAL BROILER CHICKS
    (AAU, Anand, 2016) FEFAR, DHAVAL T.; JOSHI, B. P.
    The present investigation was undertaken to study on clinico-pathological and immunomodulatory effects of cow urine distillate and its synergistic action with aqueous poly herbal extract containing Ocimum sanctum (Tulsi), Tinospora cordifolia (Guduchi) and Withania somnifera (Ashwagandha in commercial broiler chicks. A total of 324 day old Cobb-400 broiler chicks were randomly divided into nine groups comprising 36 chicks in each group. Group I served as negative control without administration of any treatment except plain water at ad libitum. Groups II and III were served as positive treatment control groups and administered with IBD intermediate plus vaccine and cyclophosphamide as immunosuppressive agents respectively. The remaining treatment groups IV to IX were given either cow urine distillate alone or its combination with aqueous poly herbal extract along with intermediate IBD vaccine and cyclophosphamide. All the birds of different experimental groups were observed for different parameters. Six birds from each experimental group were sacrificed on day 0, 7, 14, 21, 28 and 35 for collection of material for haematological, biochemical, histopathological and lymphoblastogenesis study. No observable clinical signs of abnormalities were noticed in group I as well as groups (IV and V) which were given either cow urine distillate alone or mixture of cow urine distillate and aqueous poly herbal extract throughout period of experiment. Varying degree of clinical signs of the nature of tendency to remain standing at one place with apathy, unthriftiness with ruffled feathers, dullness and drooping of the wings were observed in some of the chicks belonged to positive control group II (IBD vaccinated) and group III (cyclophosphamide treated) after two to three days of administration of immunosuppressive agents. Treatment groups VI, VII, VIII & IX did not reveal any clinical signs except mild depression and dullness in occasional birds. The signs were remained for three to four days and thereafter subsided and chicks appeared healthy throughout the period of study. There was no mortality in any experimental group throughout the study period. There was significant (P<0.05) increase in mean body weight in group IV (cow urine distillate) and V (cow urine distillate + poly herbal extract) compared to negative control group I. There was also significant (P<0.05) increase in mean body weight in groups VI & VII compared to positive control group II (IBD plus vaccine treated) as well as in groups VIII and group IX compared to its positive control from 14th day till the end of experiment. There was significant difference in feed conversion ratio in cow urine distillate treated group IV as well as cow urine distillate along with poly herbal extract treated group V as compared to control group I at 28th and 35th day of experiment. There was apparent though non significant improvement in FCR observed in groups VI and VII compared to group II as well as in groups VIII and IX compared to group III from 28th day of experiment till the end of the experiment. There was significant increase in bursa body weight, thymus body weight and spleen body weight ratio in groups IV and V compared to their respective control group I from 14th day till the end of experiment. There was significant (P<0.05) increase in bursa body weight, thymus body weight and spleen body weight ratio in groups VI, VII, VIII and IX in comparison to their respective positive control group on 21st day of experiment. On this day, there was significant (P<0.05) decrease in bursa body weight ratio and thymus body weight ratio in groups II and III as compared to control group I where as there was also significant (P<0.05) decrease in spleen body weight ratio in group III as compared to untreated control group I. Different haematological parameters revealed significant decrease (P<0.05) in haemoglobin (Hb), packed cell volume and TEC count in group III on 14th and 21st day of experiment as compared to control group I. Among different treatment groups, only groups VIII and IX showed significant decrease (P<0.05) in Hb, PCV and TEC values in comparison to group I and significant increase as compared to group III on 14th day of experiment. There was significant decrease (P<0.05) in the TLC in groups III, VIII and IX as compared to group I whereas significant increase (P<0.05) in groups VIII and IX as compared to group III on 14th day of experiment. There was also significant decrease in heterophil, lymphocyte and monocyte counts in group III on 14th and 21st day of experiment as well as in groups VIII and IX on 14th day as compared to group I where as the values of heterophil and lymphocyte counts were significantly higher in groups VIII and IX as compared to group III. All these findings indicated that cow urine and its combination with poly herbal extract have ability to counteract the effect of cyclophosphamide in broiler chicks.

    “STUDIES ON VISCERAL GOUT IN BROILER CHICKS WITH SPECIAL REFERENCE TO ASTROVIRUS
    (Anand Agricultural University, Anand, 2016) Ashish D. Chaudhari; Dr. C.J. Dave
    Visceral gout is a syndrome of major concern causing heavy economic losses in broiler chicks and poses a challenge to control because of its multifactorial etiology. In present study, attempts were made to confirm association of Chicken astrovirus (CAstV) and Avian nephritis virus (ANV) with visceral gout. Gout is a disorder of uric acid metabolism that allows uric acid to accumulate in the blood and tissues. The present epidemiological study was carried out to know the autopsy incidence of visceral gout from April, 2011 to March, 2016 and classified year wise and month wise to ascertain the susceptibility and relative incidence of visceral gout in commercial broiler chicks up to two weeks of age and role of Astrovirus in the causation of visceral gout
