ThesisItem Open Access STUDIES ON THE EFFECTS OF VARIOUS FOOD -PLANTS ON THE GROWTH AND DEVELOPMENT OF B=DIACRISIA OBLIQUA AND ITS CONTROLS(Birsa Agricultural University, 1978) PRASAD, DEVENDRA; PREMCHANDResults of the effect of different food plants has opened a nar avenue for finding out the pretical utility of the toxic factor present in jorar and lantana upon which the caterpillars did not survive in the laboratory. Velvet bean, however, proved lethal in the laboratory as well as it was found free from damage by the Bihar hairy caterpillars. Regults of the chemical control suggest that the labomtory findings are not always successful to the same extent. Hence, field studies should be the basis of recommendationsof a pesticides against a particular insects. There is plenty of scope for conducting trials on the breeding and utilisation of Ganthecona bug in controlling the insects. Nuclear polyhedrosis has a potential value for the control of the insects. This may be taken up for a detailed study.ThesisItem Open Access Possibilities of increasing income jin Dryland Farming(Birsa Agricultural University, 1980) Tudu, Tika Ram; Singh, R.K.The present study is undertaken to assess the possibilities of increasing income in dryland farming with existing technical know-how and resource supplies. For the particle purpose. Dryland project at chandwa and its adjacent villages were selected. The various aspects of cost and return were collected £ron forty randomly selected farmers through personal interview to workout input-output coefficient. Later on farmers were differentiated into three different group’s viz. small, medium and large groups according to size of holding ranging between 0 to 5 acres, 5 to 10 acres and more than 10 acres respectively. The optimum plans were developed for each group of farms by adopting linear programming techniques. The optimum plans with their respective existing plans have been compared in respect of land use, cropping pattern and farm income. The study reveals that the farm income in different classes can be increased to higher level by adoption of optimum farm plans in place of existing plans. In all cases superiority of optimum plans over present plans is distinctly noticeable. On the basis of observations and analysis of the present study, the suggested optimum plans for dryland farming area have capabilities to increase the farm income to cons durable higher level. It is very clear from the study that adoption of optimum plans may combat the low productivity and uncertain farm returns of the dryland farming area.ThesisItem Open Access Genetic studies on pattern of Growth Rate and Milk Production in Goats(Birsa Agricultural University, Ranchi, 1980) Kumar, Ravindra; Singh, C.S.P.1.Types of single, twin and triplet kiddings (in percentage) in Black Bengal goats carrying kids of the same breed were 78.86, 21.14 and 0 respectively. Corresponding values were 72.38, 26.67 and 0.95 when Jamnapari+ Black Bengal kids were born. 2. The birth weight of Saanen was the highest (3.33+0.296 kg) followed by Jamnapari (2.38+0.141 kg), Saanen+Black Bengal (2.23+0.166 kg), Barbari (1.80+0.081 kg), k Jamnapari + Black Bengal (1.32 0.037 kg) and Black Bengal (1.21 + 0.027 kg) respectively. 3. The birth weight and body measurements of Saanen kids were higher than Jamnapari, Barbari, Jamnapari + Black Bengal and Black Bengal. 4. Saanen kids had initial advantage of body weight and measurements over their Jamnapari contemporaries. Which declined with the advancement in age. 5. The body weight and body measurement of Saanen kids were higher than Barbari, Jamnapari+ Black Bengal and Black Bengal till 6th month of age. 6. The average daily gains in Saanen, Jamnapari, Barbari, Jamnapari + Black Bengal and Black Bengal were 70.31± 0.004, 59.68 0.004, 48.10 0.002, 47.89 0.003 and 40.42 0.002 g respectively. 7. The effect of breed on daily gain in weight was significant. 8. Effects of breed was significant on length, height, chest girth and paunch girth at birth, 4th and 16th week.ThesisItem Open Access Studies on The Bionomics and control of Diamond Back Moth(1980) Tigga, Lucretia; Tigga, Lucretia; Prem chand; Prem chandLaboratory studies were made on the bionomics of Plutella xylestslla incubation Perion , larval and pupal periods and their survival exhibited marked effect of fluctuations with little variations in atmospheric temperature. Total life cycle occupied shorter period during warmer months and longer during cooler months.ThesisItem Open Access CHANGES IN SOILS PROPERTIES UNDER DIFFERENT TOPOSEQUENCE AND LAND USE SYSTEM(Birsa Agricultural University, 1981) JAISWAL, Ashok Kumar; MATHUR, B.S.From the studies made in this project on soils. developed from the same parent material - Granite gneiss. under similar climatic conditions but differing in land situations and management practices, the following conclu sions can be drawn in respect of the variations in their properties.ThesisItem Open Access Studies on Bionomics and Control of Rice Gall Midge(Birsa Agricultural University, 1981) Choudhary, Rajeev Kumar; PremchandSeveral grasses serve as alternate host of rice gall midge(orseolia oryzee wood – mason)with a view to know that how the population of rice hall midge develops on grasses, when rice crop is also standing in the field a fortnightly survey was conducted in and around university farm between july and September 1985. The gale midge could be found on three grasses viz eleusins indica recorded the maximum infestation in 3rd week of july and this was the peak period of activity . other two grasses viz. Eleusine indica,Bothriochloa sp. And paspalum sp. Eleusine indica recorded the maximum infestation in 3rd week of july and this was the peak period of activity. Other two grasses showed the incidence only in August. Occurrence of parasite (platygaster orysae cam.) on gall midge in case of grasses could be found in the 3rd week of july. It went on increasing till first week of September. Probably this high level of parasitism resulted in nil population of gall midge in the 3rd week of September. In case of rice , incidence of orseolia oryzae (wood mason) was recorded in the middle of August.The peak period of activity could be observed in last week of September. Later, a sharp fall in incidence was noticed. Polyembryonic species of parasite (platygaster oryzae cam.)was recorded from galled tillers of rice in last week of August. Level of parasitism increased gradually and reached its peak in the 4th week of October. This high level of parasitism probably reduced the gall midge population to nil in the first week of November. In the chemical control trial of rice gall midge quinalphos 50 gave better performace followed by rice husk + quinalphos EC in case of broadcast sowing followed by bushening.In this cultural practices, quinalphos 5G showed the lowest incidence and recorded the highest yield. As far as transplanting practice is concerned,Karanj cake powder + fenvalerate EC recorded the highest yield and maximum benefit cost ratio.Phorate 10G showed the lowest incidence and recorded the 2nd highest yield.ThesisItem Open Access STUDIES ON THE PATHOLOGICAL CHANGES OF EXPERIMENTAL ALDRIN POISONING IN GOATS(Birsa Agricultural University, 1981) Singh, KAUSHAL KUMAR; JHA, G.J.1.Preliminary trial was conducted on eight goats to find out the minimum toxic dose of aldrin for Indian goats. On the basis of the preliminary trial, it was concluded that the minimum toxie dose of aldrin for goats was 25 mg/k body weight. 2. The acute toxicity was produced experimentally in goats by drenching aldrin as a single oral dose at the rate of 50 mg/ka body weight, 25 = B / l * a body weight and 12.5 mg/ body weight. On the other hand, chronic aldrin toxicity was produced by administration of 2.5 mg/k body weight of the drug daily for 21 days. 3. The clinical symptoms of acute aldrin toxicity was more pronounced in the animals which were drenched with lethel doses of aldrin. Dullness, depression and suspension of rumination were evident half an hour after drenching. Froathy salivation, grinding and chumping of teeth, hyper sensitivity and convulsions were observed at least 4 hours post drenching. Unlike acute aldrin toxicity, no clinical symptoms of chronic aldrin poisoning in goats could be observed in the present study. 4.The gross lesions of acute aldrin poisoning consisted of petechial hemorrhage in the muscles, liver, lungs and kidney. The adrenal gland was enlarged. On the contrary,ThesisItem Open Access CLINICO-PATHOLOGICAL STUDIES ON JOHN'S DISEASE IN GOATS AND ITS THERAPY WITH ANTITUBERCULOUS AGENTS(Birsa Agricultural University, 1981) ZAHINUDDIN, M.; Sinha, R.P.The primary seats of involvement in this disease were the intestine and the mesenteries lymph nodes. The treatment has been found to minimize the cellular reaction of the intestinal tissue and infiltration of epitheloid cells. Administration of drugs for a period of six months could not make the animals free from M. Johnei infection. From the various parameters used to control the effects of drug therapy it was concluded that the administration of drugs for a period of six months helped significantly in maintaining the health of the goats and further that the combination of drugs containing streptomycin, isoniazid end sodium amino slaicylate was superior to that containing streptomycin, isoniazid end andcetaznona.ThesisItem Open Access Observation on Clinicopathological Changes and effect of treatment of respiratory affections in Goats(Birsa Agricultural University, Ranchi, 1981) Quasimuddin, Mohammad; Verma, B.B.Studies on some aspects of respiratory affection of goats were carried out during the present investigation. The salient features of investigations as follows: 1. The prevalence of respiratory affections in goats during the period 1977 to 1979 was found to be mostly associated with bronchopneumonia followed by pleurisy, bronchitis, rhinitis and pulmonary abscess. The morbidity was highest during the winter season followed by spring, summer and rainy season. of the affected goats 55.39 per cent were less than 4 months of age and the remaining 44.72 per cent were adults. 11. Further studies on the incidence of respiratory affections revealed similar pattern of morbidity and mortality. Maximum number of goats, particularly kids fell sick during the winter season whereas morbidity in spring season was the lowest. 111.Eighty goats and 90 kids were examined. Most characteristic symptoms observed in kids were fever, in an acute form of the disease, bilateral nasal discharge coughing, stunted growth, presence of abnormal lungs sound and anaemia. Bronchopneumonia and bronchitis were the commonest respiratory affections. According to the course of the disease, three forms were encountered; peracute form in which courseThesisItem Open Access Genetic and phenotypic evaluation of different economic traits in OT and OM strains of white Leghorn Birds(Birsa Agricultural University, 1981) Singh, Lal Babu; Singh, R.L.The present study was undertaken to compare two strains (OT and OM) of white Leghorn birds at initial stage of lay with respect to various production and reproduction traits besides response to selection on the basis of egg production upto 200 days of age. The average hatch weight of chicks was 31.86 0.091 and 30.00 0.372 g in OT and OM strains respectively showing significant difference between the two strains. The heritability for this trait in OT and OM strains was -0.062 ± 0.115 and -0.150 0.159 respectively. Positive phenotypic, genetic and environmental correlations of hatch weight with body weight at 20 weeks of age were obtained in both the strains. The average body weight at 20 weeks of age was 1061.35 13.00 and 1003.20 16.425 g in OT and OM strains respectively indicating significant difference between the two strains. The heritability estimates for this trait were 0.379 +0.198 and 0.829 ± 0.408 in OT and OM strains respectively. Positive phenotypic, genetic and environmental correlations were found between body weight at 20 weeks of age and egg production upto 200 days of age in both the strains, whereas this trait was observed to be negatively correlated with age at 1st lay in both the strains. The average age at 1st lay was obtained to be 164.92 0.766 and 171.22 ± 1.048 days in OT and On strains respectively. There was highly significant difference between the two strains.ThesisItem Open Access Somes aspsects of rsepeat breseding in crossbred cattle(Birsa Agricultural University, 1981) Sharma, Ram Naresh; Singh, B.K.The repeat breeding females were treated with suitable drugs selected on the basis of the results of antibiogram. The overall conception rate obtained in the treatment groups was significantly higher than that in the control.ThesisItem Open Access A STUDY ON THE ECONOMICS OF FERTILIZER USE AS EFFECTED BY DIFFERENT METHOD AND RATES OF FERTILIZER APPLICATION UNDER LIMITED IRRIGATION IN WHEAT(Birsa Agricultural University, 1981) SINGH, DIPAK; KERKETTA, R.In order to study the economics of fertilizer use with different rates and methods application under limited irrigation on wheat (Sonalika ) an experiment was conducted during rabi season of 1980-81, at the Ranchi Agricultural collage farm, Kanke (Ranchi). The soil of the experimental plot was loamy soil of average fertility. The soil reaction was moderately acidic (ph5.4). There were three levels of fertilizer 25%, 50% and 100% of the recommended dose (100:60:40). Fertilizers were applied by two Methods. (1)Broadcast and (2) Furrow placement . Half of Nitrogen and Total amount of P and K were applied (as per treatment) as basal dose and the remaining half of nitrogenous fertilizer was applied at first interculturing as top dressing. There were three irrigational treatments, one irrigation (at crow root initiation (cri), two irrigations (at CRI and jointing stage) and three irrigations (at cri, jointing and flowering stage). One common light post sowing irrigation was provided to get good germination. From the results of experiment, it was observed that under one to three irrigations, three irrigation can profitably be used for securing maximum profit. Even with one and two irrigation wheat cultivation can profitably be done under normal climatic conditions in Chotanagpur. The fertilizer dose to the tune of 25% and 50% of the recommended dose is suitable in Chotanagpur for wheat cultivation as the late are poor for better yields fertilizer should be placed in furrows. It was concluded from the experiment that the suitable and feasible technology for wheat cultivation in Chotanagpur may be with 25% to 50% of the recommended dose of fertilizer applied in furrows with three irrigation. This finding may not be very anthertic as it is based on one year experimental data and hence further research on this aspect is necessitated to confirm the findings.ThesisItem Open Access Pharmacokinetics of some chemotherapeutic agents in poultry(Birsa Agricultural University, 1981) Yadava, Kameshwar Prasad; Banarjee, N.C.SUMMARY AND CONCLUSION 1. It has been observed that sulfonamides were absorbed from the G. I. tract of birds as per pH-pka relationship. 2. Evidence has been adduced that following single dose oral administration, sulfadimethoxine, sulfamethazine, spanbolets and sulfaquinoxaline showed max) at different time intervals indicating variation in their absorption rate from the G.1. tract of birds. 3. It has been observed that sulfadimethoxine showed the highest (max) followed by sulfamethasine, spanbolets and sulfequinoxaline post-single dose oral administration. 4. Evidence has been presented that sulfadimethoxine and sulfamethasine produced effective ther) for a longer duration of time indicating their therapeutic usefulness in the systemic infections in the chickens. 5. It was observed that sulfadimethoxine gave the longest by value followed by sulfamethazine, spanbolets and sulfaquinoxeling. 6. Evidence has been adduced that the total area under the blood level-time profile (AUC) obtained after multiple oral dose administration was largest for sulfadimethoxine followed by sulfamethazine, spanbolets and sulfaquinoxaline indicating their relative bioavailability. 7. It has been observed that acetylation was one of the major pathway of aulfonamide metabolism in the chicken and the rate and extent of this biotransformation varied with different sulfonamide compounds.ThesisItem Open Access Studies on preservation of Heterospermic buck Semen(Birsa Agricultural University, 1981) Sinha, Manoranjan Prasad; Singh, B.K.On the basis of the results obtained in the experiment, it was concluded that heterospermic semen samples prepared from sires of different breed was superior to heterospermic semen samples prepared from sires of the same breed and homospermic samples.ThesisItem Open Access The performance of Rice Variety under limited input conditions(Birsa Agricultural University, 1981) Rahman, Azizun; Verma, U.K.Significant loss of sodium on the 5th day of diarrhoea(140.83+0.7 to 140.26+0.61 mmol/1) from the normal value of 149.42+0.52 mmol/1 was noted. On the other hand significant increase level of potassium on the day S (5.41+0.03 to 5.4+0.03 mmol/1) was noted relative to the normal level of 4.9+0.03 mmol/1. On oral fluid therapy gain of the body weight was 4.84+0.36 to 8.07+0.05% on the 7th day of treatment. The packed cell volume on this day of treatment came down significantly to 0.28+0.002 to 0.29+0.002 whereas the blood pH increased significantly to 7.30+0.05. Increase in the blood glucose and total serum protein levels were noted on this date of hydration in the kids. Serum sodium level increased significantly on the 7th day of oral therapy whereas potassium level decreased significantly on this day. It was concluded that the oral fluid containing sodium chloride, calcium gluconate, magnesium sulphate, potassium dihydrogen phosphate, dextrose and glycine was highly effective and superior to the fluid containing sodium chloride sodium bicarbonate, glycine and glucose.ThesisItem Open Access Anoestrum in crossbred cattle and its response to treatment with secrodyl(Birsa Agricultural University, 1982) Singh, Jaswant; Singh, B.K.On the basis of the results obtained in the present study, it can be safely concluded that the optimum dose of Secrodyl is, 2 ml intramuscularly on the first day followed by 1 ml intramuscularly daily for next 3 days for the treatment of true anoestrum in cattle.ThesisItem Open Access STUDIES ON GENITALLA OF SOWS(Birsa Agricultural University, 1982) DAS, PRAMOD KUMAR; Singh, B.K.1.The results obtained in this study was based on examinations of 301 genital organs of female pigs, procured from Government Bacon Factory, Ranchi, during the period from December 81 to July ¹82. 2. Only non-gravid genitalia were used for the study and they belong to four breeds of pigs - Landrace, Yorkahire, crossbred and deshi. 3. Four age groups were made 6 to 12 months, 12 to 18 months, 18 to 24 months and 24 to 48 months and the results obtained in different age group were compared. 4. Observations were made on these aspects biometry of genitalia, abnormalities in pig genitalia and histopathology of same diseases. 5. Two hundred and forty one normal genitalia were used for biometrical study. 6. Sixty (19.94%) genitalia were found to be grossly abnormal. 7. On the basis of palpable structures, left ovary was found to be more functional than the right. 8. Non-significant effect of breed was observed on all the measurements of ovary except thickness. 9. The oviduct of exotic and crossbred pigs was found to be longer than the deshipigo.ThesisItem Open Access Studies on Host-Parasite Relationship and chemotherapy of Paramphistomum cervi in Goats(Birsa Agricultural University, 1982) Singh, Rajeshwar Prasaf; Sahai, B.N.The present study was undertaken to find out the effect of pure Peremphistomuncervi infection on biochemical, haematological, histopathological and histochemical alterations in goats. An attempt was also made to find out the suitability of immuno-diagnosis and chemotherapeutic agents in the diagnosis and treatment of paramphistomiasiscervi, respectively. BIOCHEMICAL STUDY. During the present study, estimation of total serum protein indicated highly significant (at 1% leve decrease in total serum protein on 20th day post-infection whereas the decrease in total serum protein per cent was significant at 5% level on 40th day after the infection. However on 60th day the decrease in total serum protein was not significantly different from the control value. HAEMATOLOGICAL STUDIES. Hematological studies further revealed severe anemia from 10th day till 60th day post-infection. Both hemoglobin, packed cell volume per cent and total erythrocyte count showed significant to highly significant decrease after E. cervi infection in all experimental kids. On the other hand total leucocyte count was significantly elevated (PL 0.01).
