ThesisItem Open Access Studies on Some Aspects of Caprine Mycoplasmasmosis(Birsa Agricultural University, Ranchi, 1987) Anup Bhaumik; B. B. VermaThe present study was conducted on some aspects of caprine mycoplasmosis. The salient features of the investigation were: 1. The incidence of Mycoplasma species in natural cases of pneumonia in kids was found to be 20.7 percent. This was lower than found earlier by other workers. The present result indicated that control and preventive measures taken against the infection were effective. 2. Two mycoplasmas ware isolated from these cases: M. mycoides subsp. mycoides (81.8 %) and Marginini (18.2 %). 3. The strain of M. mycoides subsp. mycoides isolated from clinical cases was found to be highly pathogenic as it produced mycoplasmia in mice and a typical disease of broncho-pneumonia in kids. All the kids died between 8 and 16 days post inoculation, showing symptoms of acute pneumonia. 4. The nasal discharge of experimentally infected kids was found positive for . mycoiden subsp. mycoides on 6th day post inoculation and remained positive till the kids died. 5. Agglutinins appeared on 12th day post inoculation in 2 kids and in 3 Kidson 14th day. Thus agglutination test was not found sensitive test to detect, agglutinins or diagnose the disease at the earlier stage.ThesisItem Open Access Experimental Studies on oral fluid Therapy in Goats Diarrheic Goats(Birsa Agricultural University, Ranchi, 1987) Abdul Salam Osmani; R. P. SinhaThe opidemiological investigation revealed that the majority of goats suffered from diarrhea when they approached lush green grasses. The overall incidence of diarchoae in adult goats was 16.3% in a population of 350 goats. The analysis of different causative agents of diarrhoea indicated 59.65% of goats suffered from diarrhoes due to bacteria, 10.52% due to haemonchus infection, 3-51% due to trichuris infection, 3.52 due to trichostrongylus infection and 22.81% due to dietetic errors. Among the bacteria E coli was the onlyisolates from diarrheic goats. All isolates of g coli ware tested biochemically and the serotypes 024 025 °45′ °54' °61 °121* °138 148 and untypable strains were isolatad, out of which only 028 and 045 serotypes were found highly pathogenic. Majority of E. coli strains ware sensitive to chloramphenicol. Diarrhea vas induced in goats by administering magnesium sulphate which caused gradual loss of body weight and on day 9 of diarrhea there was 10.54 ± 1-24 to 10.58 1.32% loss of body weight. Such a model to study the fluid volume and electrolyte losses in adult ruminants, as a result of diarrhoea was made for the first time. Significant rise of packed cell volume (0.37 0.009 to 0.38 0.013 1/1) from normal 0.29 0.010 to 0.32 0.012 1/1 was noted significant fall of blood pH (7.08 0.051 to 7.16± 0.021) in diarmhoaic goats was noted on day 9 of diarrhoeaThesisItem Open Access Studies on Contagious Caprine Pleuropnemonia with Particular reference to its Sero- Prevalence Determination by Complement fixation test(Birsa Agricultural University, Ranchi, 1982) Gopal Singh Kansam; B. B. VermaPresent investigation was carried out to map out of the prevalence of contagious caprine pleuropneumonia of kids in ICAR Coat Unit, Ranchi Veterinary College, Ranchi and goats of Menipur, in order to map out its prevalence a total of 218 goats from Cost Unit of Ranchi Veterinary College, Ranchi and Spon five districts of Manipur were studied. Out of 163 goats from ICAR Goat Unit, Ranchi Veterinary College, Ranchi, 71 were Black Bengal, 92 were cross-bred (Block senal x Jamunopori), 52 were mole, 111 female, 60 vere 0-3 months of age, 58 were 3-6 months of age and 37 were 6 months above. Serum samples were collected from each of 163 goats. These were tested for complement fixing antibodies using Mycoplama Acalacting antigen. The distribution of goats showing highest or antibodies according to age, sex and breed indicated that more younger kids of 0-3 months (35.2) were highly significant than the kids of 3-6 months (31%) and 6 months above (21.6 s). There was no significant difference as far as sex was concerned. Similarly, no significant difference was also observed in the two breed groups of pure Black Bengal and Cross bred (Black Dangel x Jamunapari). A comparison of reactor rates to different categories of animals suggested that the contagious caprine pleuropneumonia (CCFF) was exclusively confined to the goat population irrespective of age, sex and breed of the animale.ThesisItem Open Access Studies on Incidence on Chemotherapy of Bovine trypanosomiasis (Trypanosma evansi)(Birsa Agricultural University, Ranchi, 1984) Kafeel Ahnad; B. B. Verma1.studies on incidence of surra in cattle and buffaloes were carried out by examination of blood smears and care prepared from enlarged lymph nodes in all 240 number of cattle and 87 buffaloes were examined out of this 19 of cuttle (7.91 %) and 9 of buffaloes (10.34 %) were found positive. Thus overall incidence of disease in cattle and buffaloes ware (8.56 %). II. 22 clinical cases showing nervous symptoms were also investigated only 2 of them were found positive for surra. other were rabies (31.81 %), avitaminosis (27.27 %), anaemia (9.09 %), paraplegia (9.09 %), parturient paresis (4.54%), naval 111 (4.54 %) and paralysis of hypoglossal nerve (4.54 %). In addition to 2 cases of surra showing nervous symptoms another 2 cases were also encountered in which symptoms were different. Cardinal symptoms were intermittent fever of 30 to 45 cays, progressive loss of body weight moderate degree of anemia and occasional coughing. The local strain of Trynanosona evensi was found highly pathogenic to mice all nice died between 48 and 60 hours post inoculation. Further the cross-bred calves between 1 and 1 years of age were also found to suffer from subacute and chronicThesisItem Open Access Experimental Studies on oral Fluid therapy in Adult diarrheic Goats(Birsa Agricultural University, Ranchi, 1987) Abdul Salam Osmani; R. P. SinhaPH increased significantly on day 9 of treatment to 7.34 0.021 and 7.32 0.040 in both the groups, and 2 respectively, whereas increase of ruminal fluid pH during treatment was not significant. Likewise significant increase of blood glucose level to 2.73 0.012 to 2.86 ± 0.27 mmol/1 was noted but the increase of serum calcium and total sarum protein was not significant during the period of ORS. Serum sodium level in T₁ group and ruminal fluid sodium level in both the groups increased significantly on day 9 of CRS whereas the increase of serum sodium level in 72 group was highly significant. But non-significant rise of serum potassium and ruminal fluid potassium level was noted during the days OF CRS in both the groups. It was, thus, concluded that the ORS II containing sodium chloride, trisodium citrate 2-hydrate, glycine and glucose was superior to ORS I containing sodium chloride, calcium gluconate, magnesium sulphate, potassium dihydrogen phosphate, dextrose and glycine.ThesisItem Open Access Studies on some aspects of Pneumonia in Kids with particular reference to contagious Caprine Pleuro – Pnumonia(Birsa Agricultural University, Ranchi, 1982) Murli Manohar Gupta; B. B. VermaPresent studies were conducted on some aspects of pneumonia in kids with particular reference to contagious caprine pleuro-pneumonia; The salient features of the investigation were i 1. Pneumonia was found to be the largest single cause of mortality among the kids. The proportional mortality ratio (P.M.ratio) was 79 per 100 deaths and the C-SDR 775 per 1000 kids. 2. The kids’ upto 6 months of age were found to be highly susceptible to pneumonia. Out of 196 deaths, 173 (88.2%) were in this age group. 3. Black Bengal and crosses of Black Bengal x Jamnapari were equally susceptible to pneumonia and sex had no significant (P 0.05) influence on the mortality. 4. Lighter kids having birth weights less than 1.5 kg were found to be significantly (PL0.01) more susceptible, to pneumonia than those weighing between 1.5 - 2.5 kg. 5. The morbidity and mortality from pneumonia was significantly (PL0.01) lover during autumn than the other three season’s winter, summer and rainy. 6. Autumn born kids were significantly (PL0.01) less prone to the disease than those born during the other three seasons.ThesisItem Open Access Studies on incidence comparative diagnosis and control of Bovine Mastities in and around Ranchi(Birsa Agricultural University, Ranchi, 1987) Bhabatosh Pal; B. B. VermaStudies on some aspects of bovine mastitis in cows and buffaloes of organized dairy farms and cases brought at the College Hospital were studied with reference to incidence, association of occurrence of subclinical mastitis with number of lactation, quantity of milk production, stage of lactation, comparison of sensitivity and specificity of indirect tests, isolation of causative organisms, in vitro drug sensitivity test, level of Chloramphenicol in blood and milk of affected buffaloes and efficacy of the treatment. The salient features of investigation were: 1. The incidence of all forms of mastitis in cows was 39.5 per cent. The incidence of subclinical mastitis vas 28.39 per cent. In buffaloes overall incidence of mastitis was 41.07 per cent. The incidence of subclinical mastitis in buffaloes vas 23.21 per cent. Thus from this study it was concluded that the incidence of subclinical mastitis both in cows and buffaloes was fairly high in this region. 2. The association of number of lactation with the occurrence of subclinical mastitis in cows was investigated. It was found that the increased number of lactation, the incidence of mastitis was high. It was 50 per cent in 4th lactation, whereas it was only 7.4 per cent in 1st lactation.ThesisItem Open Access Studies On Incidene And Chemotherapy Of Intestinal Nematodiasis In Suckling Calves(Birsa Agricultural University, Ranchi, 1990) Pradhan,Krishna; D. K. ThakurIt was observed that pomegranate on an average was 78.2% effective. Although it did not suppress faecal eggs counts completely, a distinct reduction rate of 76 % against strongyloides spp., 89 % for bursate worms, 83 % for Ascaris and 69 % for a mixed infection of ascaris and bursate worm respectively were recorded by 7th day. Cucurbit seeds however, showed an efficacy of 40 percent. A substantial pod effect was observed though complete cessation in fiscal eggs output was not found. An efficacy of 45 % and 43 respectively were noted against pure bursate infection and mixed trichuris barsate vorm by 7th day. On the other hand, an efficacy of 29 % against mixed ascaris - bursate and 99 % against strongyloides bursates infection were noted by 7th day.ThesisItem Open Access Further Studies ON Hypophosphataemia in Cattle With Special Reference To Changes in Ruminal Fluid(Birsa Agricultural University, Ranchi, 1989) Guehait, Birendranath; B.B. VermaIn Chotanagpur area hypophosphatemia is very common in cross-bred cattle. In these animals it was experienced that tendency of depraved appetite, poor growth rate, eating of inanimate objects, loss of production and progressive emaciation continued. So far, no study has been made with respect to changes in ruminal fluid in hypophosphataemic animals. With this view hypophosphataemia vas experimentally produced in cross-bred calves to study the day to day changes in ruminal fluid. Simultaneously blood changes were also studied. These observations were substantiated by extending the work on clinical cases of hypophosphataenia. Experimental calves and clinically affected animals were treated with sodiun acid phosphate by different routes. 1. Hypophosphateemia vas produced experimentally in 4 cross-bred cow calves of around 6 months age by feeding phosphorus deficient ration. 2, In about 70 days typical symptoms of hypophosphatasnia were observed when the serum phosphorus level fell down from 6.73 0.55 to 3.52 0.20 mg percent. The symptoms were anorexia, marked swelling of the knee joints, lameness, stiff gait, narrowing of pelvic cavity and chest wall, progressive loss w
