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.

    EFFECT OF PHYSICAL AND CHEMICAL AGENTS ON THE IONIC CONCENTRATION, CUTICULAR SECRETION, AND RATE OF MORTALITY IN THE DIFFERENT STAGES OF TICK, Hyalomma Anatolicum Anatolicum KOCH, 1844
    (AAU, Anand, 1984) Shah, Vallabh Ochhvolal; Avsatthi, B. L.
    The normal ionic concentration of haemolymph, cuticular secretion (wax), and rae of mortality in different stages of tick, Hyalomma anatolicum anatolicum Koch, 1844, and the alternations displayed by them to acclimatize the disturbed condition in response to the Silica (as an physical agent); Dimilin (anti-cuticulin substance), Kabat (growth regulator); and Ekalux and Sumiciddin (as an Acaricides) were investigated during present study. Such experiment on different stages of tick Hyalomma anatolicum anatolicum with different treatments indicated the potentiality of this tick to attain acclimatization easily by altering its basic homeostasis. In such tick nine biochemical characteristics were studied as a base for normal homeostasis and they were correleated with the rate of mortality in response to various treatments.

    STUDIES ON GASTRO-INTESTINAL NEMATODIASIS IN SHEEP UNDER FARM AND FIELD CONDITION IN PALANPUR DISTRICT OF NORTH GUJARAT
    (AAU, Anand, 1984) MOMIN, R. R.; Avsatthi, B. L.
    Studies were conducted from February 1983 to January 1984 (12 months). Faecal samples of 20 Patanwadi ewes, 20Patanwadi female lambs, 20 Crossbred ewes, 20 Exotic rams and 20 Marwadi ewes were collected per rectum from individual sheep at 2 week intervals. The degree of infestation was measured by egg counting and subsequent larval differentiation from faecal cultures. The post mortem materials for the study were collected for examination from sheep slaughtered in private slaughter house in Doesa. Four adult sheep of Marwadi breed were examined every month for the purpose, For Haematological study the samples from 3 Patanwadi adult ewes, 3Crossbred adult ewes and 3 Patanwadi female lambs were taken once in a month. Climatological data was collected from the Arid zone Meterological Station in Sardarkrishinagar.

    STUDIES ON ECTOPARASITES OF BUFFALOES (Bubalus bubalis) IN JUNAGADH AND KHEDA DISTRICTS OF GUJARAT STATE
    (AAU, Anand, 1988) KIKANI, M. H.; Avsatthi, B. L.
    Tick, mange-mites, fleas , lice and flies were enooantered on buffaloes (Bubal us bubalis ) during the period of investigation i.e . July 1987 to June 1988, Investigation work was canned out in Junagadh and Kheda districts of Gujarat State. The predominant species of ticks recoiled was Hyalomma anatolicum anato- licum followed by H.marginatum isaaci, Haemaphysalis bispinosa, Boophilus annulatus. B.miroplus, Rhipicephalus haemaphysaloides, and Hyalomma (H.) hussaini. H.a.anatolicum chiefly preferred to feed on perineal region, udder, scrotum, base of the tail, switch of the tail and axilla region; while H.marginatoia Isaaci preferred on perianum, base of the tail and switch of the tail; H.(H.) hussaini and Haemaphysalis bispinosa were observed on neck region; Rhipicephalus haemaphysaloides, were mainly observed on axilla and neck region; Boophilus annulatas were found on axilla and perineal region and B.mioroplus were observed on perineal region.

    INTERNAL PARASITES OF GOATS AND SHEEP WITH PARTICULAR REFERENCE TO HAEMATOLOGICAL AND BIOCHEMICAL STUDIES
    (AAU, Anand, 1989) PATEL, PREMDAS VINODBHAI; AVSATTHI, B. L.
    Present study was conducted from March, 1988 to February, 1989, Faecal samples of 30 goats and 30 sheep maintained under field and farm conditions were collected directly per rectum from individual animal at regular intervals Faecal samples were examined by Qualitative method and the degree of infection was measured by means of egg counting (Mc Master and Stoll 's technique) and larval differentiation was done by culturing faecal samples. The post-mortem materials from 24goats and 24- sheep each under field and farm conditions were collected every month and also the blood was collected for haematological study. Serum was separated out from these blood samples for biochemical study of serum calcium, phosphorus and total serum protein in infected and uninfected control goats and sheep. Study included the seasonal incidence of Fasciola gigantica Amphistomes, Trichostrongylid spp., Trichuris spp., Moniezia spp. ova in faeces. Oocyst of coccidia and cysts of ciliates. Mostly mixed infection were observed and marked variation was observed in the faecal egg count within as well as between various collections. The incidence of parasitic load was higher during monsoon as compared to winter and summer seasons.

    EVALUATION OF SOME COMMON DIAGNOSTIC PROCEDURES IN EXPERIMENTAL TRYPANOSOMA EVANSI INFECTION IN BUFFALO CALVES
    (AAU, Anand, 1982) KATHIRIA, LAXMAN G.; AVSATTHI, B. L.
    The present study..was conducted at the Department of Parasitology, College of Veterinary Science and Animal Husbandry, Gujarat Agricultural University, Anand to evaluate various reliable methods for diagnosis of latent and chronic T. evansi infection (Surra) in buffaloes. The observations regarding the symptoms exhibited by the experimentally inoculated buffalo calves, microscopic examination of their blood, haematologlcal and biochemical changes in their blood and serum, biological tests in albino rats and mice, chemical tests as well as passive haemagglutination test, were recorded. Seven buffalo calves 12-18 months of age were used for the present study, five of which were inoculated S/c with 4.5 x 10 power 7 live T. evansi and two calves were used as controls. No definitive symptoms which can help in diagnosis for presence of infection, were exhibited by inoculated buffalo calves except there was subnormal temperature (99° -102.5°F) in general, and transient enlargement of bilateral superficial lymphnodes with progressive weakness In one calf. Examination of thick blood smear was found superior to thin blood smear and wet blood preparation for detecting the trypanosomes In the circulating blood at Inoculated calves. Intermittent (periodic) paraaltaemla with varying number (0.02 to 13 per field of 45 X 10 magnification) was developed In four Inoculated calves, while blood of one calf did not reveal any trypanosomes at any day of examination upto 180 days. However, the biological tests carried out periodically in rats and mice with the blood of all inoculated buffalo calves, developed parasltaemla In respective rats and mice. The prepatent period varied In both the laboratory animals with the time of test before and after the appearance of trypanosomes in the peripheral blood of Infected calves. Prepatent period of 15 days was observed in a rat inoculated with the blood of an apparently healthy case in buffalo from field. On this base, it was postulated that the biological test is more superior than microscopic examination of blood. Haematological study revealed mild to moderate anaemia with periodic significant fall in total erythrocyte count, packed cell volume, and haemoglobin concentration. There was no significant change in total leucocyte count and eosinophils, however, significant progressive lymphocytosis and neutropenia were observed. As regards biochemical study, it revealed progressive hypoglycaeaia and late hypophosphatemia without significant changes in serum calcium and magnesium during the present study, together with haematological findings, changes in blood glucose and serum phosphorus probably indicate trypanosomal infection, however, detection of trypanosoaes on microscopic examination of body fluid and biological test can be a confirmative for Justifying the diagnosis. None of the three chemical tests viz., formolgel, nercurlc ohloride and nitric acid test gave specific reactions with the sera of inoculated calves, this indicates their limitation in diagnosis of T. evansi infection in buffaloes Passive haemagglutiaation test was found sensitive as it showed the antibody titres ranging from 1:10 to 1:1280 from 7th to 120th day post-infection. On the basis of the present study, the biological testa in rats or mice can be considered as more reliable for solidifying the diagnosis of latent T. evansi infection in buffaloes.

    ECTOPARASITES OF CAMEL (Camelus dromedarius) WITH PARTICULAR REFERENCE TO TICK FAUNA
    (AAU, Anand, 1987) PATEL, ABDULKADAR ISMAIL; AVSATTHI, B. L.
    Ticks, mites, flies and myiasis producing maggots were observed on body of camels during the period of investigation i.e. March 1985 to November 1986. The predominant tick species was found to be Hyaloma dromedarii. Other species encountered were H. impeltatum. H. marginatum, H. anatolicum anatolicum, H. truncatum, H. hussaini and Rhipicephalus spp. H.a.anatolicum preferred to feed on perianal region, H. marginatum on perineum and below the base of tail while H. dromedarii and H. impeltatum were observed on all over the body. Other important sites included nasal nares, shoulder and throat. Clipping of hairs resulted in concentration of ticks in nasal nares and perineum. Only adults and nymphs were observed on the body of camel while larvae were never seen. Maximum tick infestation was observed during summer while low during winter reaching to the lowest level in December (Average temperature: Maximum 28.47°C; Minimum 12.17°C and relative 67.75 percent).
