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.

ThesisItem Open Access PHYSIO-PATHOLOGY OF SUMMER STRESS IN LAYERS(AAU, Anand, 1989) GHODASARA, D. J.; Prajapati, K. S.The present study was made on layer birds kept at AICRP on poultry, Gujarat Agricultural University, Anand Campus, Anand. The study was conducted during extreme period of summer heat. For comparison, base level data were obtained by conducting similar study during comfortable environmental temperature of winter season .The experimental birds were divided into five groups with different housing and managemental systems. Samples like blood, serum, plasma and tissues were collected during morning and after-noon from each group and used for the study. Study was also made on natural cases of heat stroke and FLHS. Relationship of heat stress with incidence of FLHS as well as effect of housing system were also analysed. Concentration, of thyroid hormone in plasma was significantly decreased during summer season. Serum cholesterol level decreased during summer season as well as in after-noon than morning serum samples, suggesting lowered functioning of liver under heat stress. Relative weight of adrenal gland was increased during summer season, indicating increased activity of adrenal gland. Short term increase in temperature caused increase in the glucose level while, birds exposed for long period of high cyclic temperature (summer season) caused decrease in level of blood glucose. Activities of AXF and ALT increased during summer season. Thesealso increased in after-noon samples during summer season. The level of AKP was significantly higher in cage birds than deep litter birds during summer season, suggesting more stress of caging. Heat stress and housing systems did not cause any significant change in the level of total serum protein and sodium. Concentration of potassium and calcium was decreased in summer season. Potassium concentration was also decreased in after-noon serum sample in all the groups. Effects of heat stress and housing systems did not alter - the values of haemoglobin, PCV and R3C count. Total leukocytic count was significantly decreased during summer season. Further the after-noon blood samples also showed decrease in TLC in summer season. Absolute count of heterophil increased and lymphocytic count decreased during summer season. Number of heterophil was also increased in after-noon blood samples during summer season while, it was reverse for lymphocyte. Seasons and housing systems did not cause any significant change in the number of eosinophils and monocytes. Increase in environmental temperature directly correlated with the increase in H:L ratio and was found to be a good measure of stress to the chickens. Birds sacrificed in the after-noon during summer season showed mild fatty changes in liver and congestion in trachea and lungs. Severity of these lesions increased in the birds, died due to heat stroke. Birds under summer groups showed variable degree of hyperplasia of interrenal cells of adrenal gland. Thyroid acini were lined by flattened epithelium. More or less similar microscopic lesions were also observed in the birds, died due to heat stroke, but severity was increased. Amount of fat deposition increased in the liver samples, collected in the after-noon during summer season. Maximum mortality due to heat stroke was observed in the month of May. Increase in mortality due to FLHS was correlated directly to increase in the environmental temperature. Mortality due to FLHS v/as significantly higher in the cage birds than deep litter birds. Striking gross lesions in FLHS were highly friable and fatty liver leading to rupture and fatal internal haemorrhages. Liver sections stained with Oil Red 0 from cases of heat stroke and FLHS showed increased deposition of lipid in hepatic cells.ThesisItem Open Access TOXICOPATHOLOGICAL STUDIES ON 'NALED TECHNICAL' IN RATS AND DOGS(AAU, Anand, 1989) DAVE, C. J.; Heranjal, D. D.The study on toxicopathological effects of naled technical was undertaken in rats and dogs. Naled technical (1-2, dibromo 2,2 dichloroethyl dimethyl phosphate) was given intragastrically to obtain the oral LD50 in laboratory inbred albino rats (Ratus morvegicus) which was found to be 425 mg/kg body weight (P0.05). Rtas of either sex were divided into four groups each comprising of three male and three female. Group I was provided with plain ground feed (without naled) which served as control. Group II, Group III and Group IV were given 12.5 25 and 50 mg naled per kg of feed, respectively. Weekly body weight was recorded and experiment was conducted in natural day-night rhythm. Initially u[pto four weeks, rise in body weight was observed compared to control which started decreasing after seven weeks of experiment.ThesisItem Open Access BOVINE LYMPHOSARCOMA IN CROSSBRED CATTLE HISTOPATHOLOGICAL, HAEMATOLOGICAL AND SEROLOGICAL STUDIES(AAU, Anand, 1980) VARGHESE, KOSHY; Heranjal, D. D.A rare case of lymphosarcoma in a Jersey X Kankrej cow with profuse enlargement of peripherial lymph nodes was studied in a crossbred farm near Anand, Gujarat. A number of other in a crossbred cattle were also showing enlargement of peripheral lymph nodes. The biopsy material of the peripheral lymph nodes of some of these cattle revealed lesions of lymphosarcoma. Two animals were euthanised and the autopay confirmed the biopsy findings and one animal died of lymphosarcoma. Haematological examination of all the animals revealed no significant or pathognomonic picture.ThesisItem Open Access EXPERIMENTAL STUDY ON PATHOLOGY OF CL. welchii TYPE D EPSILON TOXIN IN MICE AND Past. multocida IN RABBITS(AAU, Anand, 1988) PATEL, MAHESH B.; Heranjal, D. D.A.Pathological study on Cl. welchii type D in mice The study on pathology of Cl. Welchii type D epsilon toxin was carried out on healthy white Swiss mice which were injected with 0.1 ml of 1 : 1000 MLD intravenously. The disease was characterised by rapid and fatal course with a gradual development of symptoms and microscopic lesions in various organs.ThesisItem Open Access ETIOPATHOLOGICAL STUDIES ON CHICK MORTALITY(AAU, Anand, 1986) NAIK, ASHOK B.; Heranjal, D. D.Etiopathological study on mortality of chicks at the time of hatch and during 0 to 8 weeks of age was undertaken in seven hatches of three hatcheries and eight flocks of seven poultry farms situated in Gujarat State. Bacteriological, Vigrological, Parasitological and Histopathological studies were undertaken to know the cause of mortality. Escherichia coli, Streptococcus species and Staphylococcus species were found responsible for causing average mortality of 10.48 in chicks at the time of hatch.ThesisItem Open Access A STUDY ON PATHOGENESIS OF EXPERIMENTAL TRYPANOSOMA EVANSI INFECTION IN LABORATORY ANIMALS-ALBINO MICE, RATS AND RABBITS(AAU, Anand, 1982) Patel, Naresh M.; Heranjal, D. D.Study on pathogenesis of T. evanai was carried out in albino mice, rats and rabbits which were artificially infected with T. evansi. In mice and rats, the disease was characterized by rapid and fatal course with a steady increase of trypanosomes in the blood circulation, while in the case of rabbits, the disease took a chronic course with a relaping type of infection. Blood glucose level significantly decreased during the course of infection in all the three species of laboratory animals. Differential leucocyte count revealed significant neutrophilla, lymphopenia and monocytosis, which were expressed through a significant increase in the values of Neutrophil - Lymphocyte Index (N.L.I.) and Monocyte- Lymphocyte Index (M.L.I.) in mice and rats. However these values were non-significant in the case of rabbits.ThesisItem Open Access PATHOLOGICAL AND SEROLOGICAL STUDIES ON NATURAL OUTBREAKS OF ACUTE (VISCERAL) MAREK'S DISEASE IN CHICKENS(AAU, Anand, 1989) DAVE, PURNIMA N.; PRAJAPATI, K. S.Outbreaks of acute form of Marek's disease were studied in five successive flocks (AKP, RBCP, AICRP, CPRS and RRS)of WIfi birds at Poultry Complex of Gujarat Agricultural University, Anand. Study was carried out on pathological and serological aspects of acute MD. Daily mortality due to MD was recorded from 11th week onwards to 45 weeks of age in a l l the five flocks. Maximum mortality of 32.09 per cent was observed in the AKP flock. The mortality was higher in the male birds than the female birds in RBCP flock while the mortality was more in the female birds than the male birds in RRS flock. No significant difference was noticed between the sexes in r e s t of the flocks. Liver was most frequently grossly affected organ in all the five flocks. The gross lesions were of nodular or diffuse type in nature. The microscopto picture was essentially the same in the various visceral organs and tissues with characteristic pleomorphic lymphoid cell proliferation. Nuclear inclusions were clearly evident in the FFE of the skin stained by Page Green stain. Impression smears prepared from nodular growths of ovary revealed characteristic infrequent pyroninophilic lymphoblasts, Serological studies showed 40 to 90 per cent seroprevalence in various flocks while FF showed 100 per cent positive reactions in all the five flocks.ThesisItem Open Access THE STUDY OF BOVINE NEOPLASMS IN GUJARAT STATE WITH SPECIAL REFERENCE TO CANCER OF HORN(AAU, Anand, 1983) JOSHI, B. P.; Heranjal, D. D.Bovine neoplasms were surveyed from the recorded cases at the Department of Pathology from 1965 to 1982, Incidence of aquamous cell carcinoma of the horn was highest amongst the reported tumours. Kankrej bullocks were found to be most succeptible to cancer of horn, The incidence of cancer of horn was found to be maximum in the age group of 7 to 10 years which happens to be the period when bullocks are used maximum for draught purposes and cows for milk purposes. In front of the observed cases paring of horn, application of oil and paints and stress appeared to be the predisposing factors to cancer of horn.
