ThesisItem Open Access Studies on Cultural And Nitrogen Management in Wheat in Rice-Wheat Sequence(Birsa Agricultural University, Ranchi, 1986) U. N. Verma; U. K. VermaStudies on cultural and nitrogen management in wheat in rice-wheat sequence were made in two sets of experiments conducted at Birsa Agricultural University Farm, Kanke, Ranchi. The first set of experiments was conducted in split plot design replicated three times during rabi seasons of 1982-83 and 1983 84. Treatment combinations consisted of two conditions of tillage (zero and optimum tillage) and four levels of nitrogen (25, 50, 75 and 100 kg ha) in main plot and four times of nitrogen application (all basal, 1/2 basal + 1/2 at CRI, 1/2 basal + 1/2 at boot and 1/3 basal + 1/3 at CRI + 1/3 at boot) in sub plot. The second set of experiment was conducted in a factorial randomi seed block design with four replications. The treatments consisted of combination of two tillage conditions (zero and optimum tillage) and three methods of weed control (unweeded check, two hand hoeings at 15 and 30 days after sowing and post-emergence application of 2,4-D at the rate of 1 kg a.e. ha). Wheat variety tested was Sonalika. The soil of the experimental plot was loam to silt loam in texture, medium in fertility and acidic reaction. Ploughing reduced bulk density and organic carbon content of soil but it had no effect on germination and seed ling establishment of wheat. Number of weeds m -2 was higher under optimum tilled plots but dry weight of weeds was greater under zero tillage. Untilled plots showed comparatively lower dry weight of roots at maximum tillering stage, however, the difference was gradually reduced at flowering. But for number of effective tillers no other yield attribute was markedly affected by Variation in tillage condition. Grain yields from optimum tilted plots were only 7 to 10 per cent more than that from the zero tilled plots (direct drilling of wheat in between two rows of rice stubbles). Energy use efficiency (BUB), grain energy productivity (g wheat MJ1) and benefit cost ratio on the other hand, were greater under zero tillage condition. Consumptive water use was higher under optimum tilled plots than under zero tilled plots. Consumptive use rate , increased from seedling to boot stage and then declined gradually during maturity. Crop responded well to nitrogen application up to 100 kg ha. Best indices of yield attributes, higher grain and straw yields, better uptake of nitrogen, higher EUS, energy productivity, net profit and benefit cost ratio were obtained when 50 per cent nitrogen was applied basal and 50 per cent at CRI stage. Late application of nitrogen at boot stage increased the test weight of thousand grains and protein con tent of grain .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 Quantitative And Qualitative Dietary Restrictions And Their Influence On The Performance Of Layers And Broilers(Birsa Agricultural University, Ranchi, 1989) Prasad, C. M.; R. R. P. SinhaOn the basis of the experiment conducted on layers and broilers during different periods of their growth and production, the following conclusion may ne drawn. 1. Expeller pressed kosum cake (PKC) protein is not a suitable substitute for groundnut cake protein, however, it may be added in layers' diet upto a maximum level of 6.0 % of the mash for a short period during scarcity. 2. Solvent extracted kosum cake (SEKC) protein can replace the groundnut cake protein at 5% of the mash success fully. However, it may be used upto 20% level on isocaloric basis in layers diet for economical egg production for short period during scarcity. 3. Skip-a-day feeding during laying period is not economical, as such, it should not be practiced. 4.Skip-a-day feed with or without SEKC (0, 50 and 70 % replacement of groundnut cake nitrogen) supplementation during growing (13-22 weeks) period is beneficial for subsequent egg production in WLH chicks.
