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.

    STUDIES ON MYCOTIC MASTITIS IN EXOTIC AND CROSSBRED CATTLE WITH SPECIAL REFERENCE TO ITS INCIDENCE AND DIAGNOSIS
    (AAU, Anand, 1984) SIMARIA, MULJI B.; DHOLAKIA, P. M.
    The present study was taken up to assess the incidence of mycotic infections of under in apparently healthy quarters of lactating cows and diagnosis in milk samples from clinical cases, Simultaneously, the prevalence of subclinical mastitis (SCM), and pathogenicity of fungal strains were also studied. The milk samples from 150 lactating cows (53 Jersey, 30 Kankrej and 67 crossbred) were collected. In addition to this 82 milk samples from clinical cases of mastitis received in Department of Bacteriology were also included in the present study. Subclinical mastitis (SCM) was recorded as 15.33 and 5.27 per cent on animal and quarter basis with California Mastitis Test. Although, incidence of SCM was highest in Jersey herd (8.82% quarterwise), fungal isolation was as low as 2.45 per cent, Hence CMT did not prove efficient enough to detect fungal infection in apparently normal udders.

    STUDIES ON ADVANCED METHODS OF ASCERTAINING BRUCELLOSIS IN CATTLE
    (AAU, Anand, 1985) PATEL, J. B.; JHALA, V. M.
    The disease Brucellosis caused by the infection of Brucella abortus in cattle adversely affects the economy of livestock rearing due to losses of calves created by abortions in suffering animals along with loss in milk production. The disease is worldwide in distribution and calves lost due to abortions create highly adverse economic impact on the animal husbandry development. The disease also occupies a special importance being zoonotic in nature. It is# therefore, essential to diagnose the disease in a herd as early as possible for its effective control. It is now well established that the Brucella organisms being the facultative Intracellular organisms the cellular immunity plays a major role in the host resistance. In view of the above facts, the present work was carried out in cows at Livestock Research Station, Gujarat Agricultural University, Sardar Krushinagar, employing following six parametars to study their efficacy. (1) Screening of individual cow by milk ring test using ABR i.e. Aboirtus Bang Ring Antigen. (2) Above cows and the cows which were not in milk but having the history of abortion, were subjected to serum plate agglutination test. (3) All above sera samples were further examined by Serum Tube Agglutination Test (STAT). (4) Fourteen sera samples from positive, doubtful and negative reactors to STAT were sent to International Brucella Laboratory, Indian Veterinary Research Institute, Izatnagar for confirmation by complement fixation test. (5) Determination of conglutinin (K) and immunoconglutinin (IK) level in sera of positive, doubtful and negative reactors to STAT . (6) Measurement of cell mediated immunity in vitro by leucocyte migration inhibition test. Prom the results obtained it could be concluded that:- i)The serological tests namely milk ring test plate agglutination test, tube agglutination test may serve as useful tool for diagnosis of brucellosis in a herd. ii) The level of K and IK in sera of positive, doubtful or negative reactors to STAT have no significant difference and there was no significant correlation with agglutination titre, hence the determination of K and IK may not be of use in diagnosis of Brucellosis. iii) The Brucella organisms are being the facultative intracellular micro organisms, the cell mediated immunity plays an important role in resistance. The measurement of cell mediated immunity in vitro by leucocyte migration inhibition test led to the conclusion that this test may be of very great value as a modern advanced method for the diagnosis of Brucellosis where cellular immunity is considered to play a significant role.

    STUDIES ON MICROFLORA OF BOVINE SEMEN AND THEIR EFFECT ON SEMEN QUALITY
    (AAU, Anand, 1983) KHER, HIRABHAI N.; DHOLAKIA, P. M.
    Tho present study ims alaed to assess the baoterial load and types of organisms presant In saaien and their relation to semen quality. The study also included antibiotie sensitivity pattern of the isolates in vitro. Totally 45 bulls belonging to (a) Regional A. I. Centre, Rajkot, (b) Central Semen Collection Station, Mehsana, and (c) A. I. Centre, Godhra were studied during the year 1982-83. Bacterial load in the range frota 630 to 14375 organisms per ml for neat semen and in the range from 12300 to 130000 per ml for preputial washings had been encountered. The bacterial load from neat semen was high in summer season followed by monsoon and winter season, while that of preputial washings was high in monsoon season followed by summer and winter season. The semen quality was found fairly good , irrespective of bacterial load of ejaculates. Within the centre, bacterial load of neat semen and preputial washings was higher in buffalo bulls than that of cow bulls and was not varying according to type of sheath.

    QUANTITATIVE AND QUALITATIVE STUDIES ON GENITAL BACTERIA OF NORMAL AND REPEAT BREEDING BUFFALOES AND CLINICAL TRIALS WITH AMIKACIN
    (AAU, Anand, 1989) GOSWAMI, I. C.; KHER, H. N.
    The present study was aimed to assess the bacterial load and types of bacterial organisms present in cervical mucus of normal and repeat breeding buffaloes. The study also included antibiotic sensitivity pattern of the isolates in vitro and clinical trials of amikacin on selected numbers of repeat breeding buffaloes. The samples of cervical mucus were examined from 100 buffaloes, of which 35 were normal and 65 were repeat breeders. The samples were collected from A.I. Centre of Veterinary College, Anand and two villages , namely Bedva and Jitodia , near by Anand town. Bacterial load was encountered in the range from zero to 10,600 organisms per ml of cervical mucus with the average of 1,475 in normal buffaloes and in the range of zero to 1,37,000 organisms per ml of mucus with the average of 26,609 in repeat breeders. The average bacterial load was 18 times higher in repeat breeders than in normal animals. Out of the 100 samples of cervical mucus exajnined for cultural Isolation, bacterial organisms were isolated from 75 samples. Out of the 35 samples from normal animals, 18 samples were found to be culturally positive which yielded 21 isolates. Prom 65 cases of repeat breeders, 55 samples were found to be culturally positive which yielded 76 isolates . Thus, the frequency of occurrence of organisms was higher in repeat breeders than in normal group. Totally 97 isolates were recovered from 73 culturally positive mucus samples. Gram positive organisms (81.84 per cent) predominated over gram negative bacteria (18.16 per cent). Twenty five isolates of gram positive cocci were obtained which included Staphylococcus aureus. Staph.epidermidis. Micrococcus spp. and Streptococci. Diphtheroids formed predominant group (39.18 per cent) of the isolates. They included Gorynebaoterium pryogenes, Coryn.bovis, Coryn.murium, Coryn.ulcerans, Coryn.xerosis, Coryn. eq.ui. Kurthia spp, and Listeria monocytogenes. Gram positive spore forming bacilli constituted 16.48 per cent of the isolates. They were Bacillas circulans, B.cereus, B.maceran, B.bad ins, B.firmus, B.coagulans and B.megaterium. Eighteen isolates (18.56 per cent) of gram negative bacilli were recovered which included Sscherichia coli, Snterobaoter cloacae, Pasteurella haemolytica, Acinetobacter lwoffii, Pseudomonas aeruginosa, Klebsiella aerogenes and untypable gram negative bacilli. Out of seven drugs tested, chloramphenicol was found to be the most effective with only 21.65 per cent of organisms resistant to it . The resistance of the Isolates observed to different drags was as follows: gentamicln - 25.77 per cent, Go-triaoxazole - 41.24 per cent, tetraoyolin - 42.67 per cent, streptomycin - 53.76 per cent, furazolidone - 63.91 per cent, and penicillin - 69.08 per cent. Clinical trial with amikacin on 22 repeat breeding buffaloes showed that average bacterial load in the cervical mucus before the treatment was 37,551 organisms per ml of mucus, whereas it was 4,600 organisms per ml of mucus after treatment. The count after treatment was 35.61 times less than the count prior to the treatment. The in vitro sensitivity trial of the isolates also showed that amikacin was the most effective drug with only 20 per cent of the isolates resistant to it. It was concluded that the bacterial load was significantly higher in cervical mucus of repeat breeders when compared to the mucus in normal fertile animals. The gram positive bacteria predominated over the gram negative bacteria. Of all the drugs tested in vitro, chloramphenicol was found to be the most effective on bacterial isolates. There was significant effect of amikacin on bacterial load of cervical mucus in the repeat breeders which correlated well with in vitro sensitivity trials.

    STUDIES ON CONGLUTININ AND IMMUNOCONGLUTININ IN JOHNE'S DISEASE IN SHEEP
    (AAU, Anand, 1984) PATEL, S. M.; JHALA, V. M.
    Johne’s disease is one of the naturally occuring debilitating infectious disease of farm animals. In sheep, it affects the health of sheep and thereby wool and mutton production. It is, therefore, essential to diagnose the disease in flock as early as possible for its effective control. Various tests are employed to establish its prevalence of detection of the disease in farm animals, however, from the perusal of literature, it was evident that no studies seem to have been made to correlate the levels of cogultinin (K) or immunoconglutinin (IK) in the sera of sheep suffering from Johne’s disease and its utility in early detection.

    SEROEPIDEMIOLOGY, EXPERIMENTAL INFECTION AND IMMUNOSUPPRESSIVE EFFECT OF INFECTIOUS BURSAL DISEASE VIRUS
    (AAU, Anand, 1989) JHALA, M. K.; KHER, H. N.
    Infectious bursal disease (IBO) is considered as one of the major infections of poultry, and owes its significance by its immunosuppressive effect, which not only leads to the activation of the silent infections,but also brings about suppression of immune response to various vaccines. Present study was aimed at the seroepidemiology, pathology and immunosuppressive effect of Infectious bursal disease virus (IBDV) in poultry. Out of the 420 sera tested, 116 (27.61 per cent) were found to contain precipitins against IBDV by Agar gel diffusion test (AGDT). Seroprevalence was only found in Surat (98.05 per cent) and Baroda (19.83 per cent) districts , while Kheda and Ahmedabad districts were found to be free from the seroprevalence of IBDV at the time of the study, indicating the existence of IBD in the south Gujarat. Out of the 35 bursal samples processed by AGDT, not a single bursa tured out to possess IBDV antigen, indicating the existence of sub-clinical form of IBDV in the south Gujarat.
