ThesisItem Open Access Antibacterial Study of A Few Indigenous Plants Commonly Found in Jharkhand(Birsa Agricultural University, Ranchi, 2001) Sushma Tigga; J.P. SonamWith an objective of formulating herbal preparations for treatment, antibacterial property of 30 locally available indigenous plants was assessed over five common pathogens of man and animals namely (1) Bacillus anthracis (2) Staphylococcus aureus (3)Salmonella paratyphi B (4) Escherichia coli (5) Beta haemolytic streptococcus Crude, aqueous, alcoholic and ether extracts of the plants were screened by disc diffusion technique. Minimum inhibitory concentration/minimum bactericidal concentration (MIC/MBC) value were determined with the preparation possessing antibacterial property by serial tube dilution technique. Thirty plants examined were Imli (Tamarindus indica), Babul (Acacia arabica), Sharifa (Annona squamosa), (Dendracalamina)ThesisItem Open Access Effect of Supplementation of Antistress agent on the performance of Broilers under different system of management(Birsa Agricultural University, Ranchi, 2001) Pankaj kumar; C,M PrasadThe experiment conducted on commercial broilers with different antistress agents have the following conclusions. Supplementation of zeetress as antistress agent was found to be the best over glucose and honey in improving the body weight gain, feed conversion ratio, haematobiochemical profiles, carcass characteristics and survivability of broilers for a period of 6 weeks under cage and deep litter systems. The performance of broilers raised under cage system of management were found to be better than deep litter system with different antistress agents tried in the experiment. The be The beneficial effects of zeetress and honey over glucose and control were possibly due to better adaptogenic and stress alleviating effect. The inclusion of zeetress and honey in the broiler rations were found to be beneficial for commercial broiler production.ThesisItem Open Access Studies On Dehydration With Special Reference To Electrocardiographic Changes And Their Amelioration In Canine(Birsa Agricultural University, Ranchi, 2001) Ansar Ahmed; S.HaqueThe work as "Studies on dehydration with special reference to electrocardiographic changes and their amelioration in canine" was conducted in the Department of Medicine, Ranchi Veterinary College, Ranchi from March, 2001 to August, 2001. The salient features of investigation were summarized as follows. Studies were conducted to screen out the cases of dehydration in dogs in Ranchi by electrocardiographic (ECG) changes, total serum protein and packed cell volume alterations. The experimental studies were made to observe the symptoms and to record the electrocardiographic, biochemical and haematological changes in pups of experimental and control groups.ThesisItem Open Access Immunological Studies on Salmonella Pullorum Vaccine Chicks(Birsa Agricultural University, Ranchi, 2001) Anjuman Ara; B.K. Tiwary1.Inactivated Salmonella pullorum (E-404) vaccine was found to be good immunogenic and elicited both humoral and CMI response. 2.Levamisole was able to enhance both humoral as well as CMI response. 3. Inactivated Salmonella pullorum (E-404) vaccine + levamisole gave 100 % protection, whereas inactivated Salmonella pullorum (E-404) vaccine was able to protect only 80% of chicks, challenged with 10 LD,, dose of virulent Salmonella pullorum bacteria. 4. DABG and DATG proved to be good immunosuppressant and specific in their action. 5. Humoral immune response was more suppressed by DABG whereas DATG profoundly suppressed the cell mediated immune response. 6. The protection percentage in the group of chicks immunized with inactivated Salmonella pullorum vaccine was low in DATG treated group in comparison to DABG treated group. 7. On suppressing T cells, mortality was higher than after B cells suppression in chicks challenged with 10 LD,, dose of S. pullorum. 8.Cellular immune response plays definite role in protection against Salmonella pullorum infection in chicks. However, some role in defenses mechanism is also played by humoral immunity and both are involved in protecting the birds against the menace of this dreaded salmonellosis i.c. pullorum disease.ThesisItem Open Access Micronutrients Status And Their Supplementation In Relation To Reproductive Performance of Crossbred Cows(Birsa Agricultural University, Ranchi, 2001) Asad Hussain; A.K.SinhaThe present study was carried out at Military Dairy Farm, Namkom. A total of 36 crossbred cows (first to third calvers) were selected and distributed in three groups. 2. Two Nutrisacc boli twice daily orally were fed to each animal in one group (T₁) and 4 gm of Biochrome powder once daily in second group (T₂) from 15 days before the expected date of calving to 15 days after calving. Third group (T3) was kept as control. 3. Four micronutrients viz., iron, copper, manganese and zinc were estimated in sera samples of 18 cows (six from each group) on 15 days before expected date of parturition (D-15), on the day of parturition (D'0') and on day 15 after parturition (D+15) were estimated by Atomic Absorption Spectrophotometry (GBC Model 902). 4. Increasing trends in average values of micronutrients were recorded in both the treated groups (T, and T₂) at D '0' and D +15 with the highest values at D+15. 5. Highly significant effects of treatments on average serum values of micronutrients were observed at D+15. 6.Average serum micronutrient values were higher in both the treatment groups (T, and T₂) as compared to control group (T₂). 7. Average serum micronutrients values were higher in Nutrisacc bolus fed group (T₁) than Biochrome powder fed group (T₂). 8.Average interval from parturition to first estrus was shortest (76.57) 11.09) in Biochrome powder fed group (T₂). 9 Average interval from parturition to fertile estrus was also shortest (129.46± 16.51) in group T₂. 10. Average number of insemination per conception was lowest (2.53 +0.38) in group T₂ 11. Lowest incidence of retention of foetal membranes (6.66 %) was recorded in group T₂ 12. An increasing trend with respect to average birth weight and subsequent body weight of female cows was observed in group T₂ 13. Average milk yield was higher in groups T, and T₂ than in group T₁ recorded at weekly intervals. 14. Better reproductive performance, more body weight gains in female calves and better milk yield were observed in the cows of Biochrome powder fed group (T₂).ThesisItem Open Access Clinicopathological and Biochemical Studies in Mange in Pigs(Birsa Agricultural University, Ranchi, 2002) Pratima Minj; S.HaqueStudies on mange infection in pigs were conducted in Department of Veterinary Medicine, Ranchi Veterinary College, Ranchi. The work was done with respect to manage infection prevailing in different age groups and breeds considering both sexes of swine. 1.The highest incidence of mange infection was recorded in older age (28.00%) than in younger age (8.80%). 2. The highest incidence of mange infection was observed in female (18.54%) than male (10.79 %). 3.The incidence of mange was more or higher in Desi (26.9%) breed than the other breeds like Tamworth (16.12%) , Hampshire (11.64%), Large White Yorkshire (14.38% ) , Russian Charmukha (25.00% ) , Landrace (20.00%) and T & D (14.85%).ThesisItem Open Access Pharmacological Studies of Anti hyperglycemicActivity of Some Indigenous Plants in Rabbits(Birsa Agricultural University, Ranchi, 2002) Nrip Kishore Pankaj; Dr.M.AlamHolanhena antidysenterica and Caesalpinia bonduc have shown promising antihyperglycamic effects in fasting as well as post-prandial hyperglycemic rabbits. Both test drugs in post-prandial normal rabbits produced hypoglycemia, however C. bonduc produced hypoglycemic effect in fasted as well as fed normal rabbits. These test drugs had antihypercholesterolemic effect in fasted as well as fed hyperglycemic rabbits; no such effect could be observed in normal rabbits. The seed powder of Holarrhena antidysenterica and Caesalpinia bonduc could reduce fasted as well as fed BUN / serum urea level in hyperglycemic rabbits. But this effect was not observed in normal rabbits. These indigenous drugs have no effect on hemoglobin percent. Test drugs nad no significant effect on gain or loss in the body weight, although Caesalpinia bonduc treated group had little gain in the body weight but reverse was with Holarrhena antidysenterica treated groups. Histopathological findings indicated toxic effects of Caesalpinia bonduc on vital organs like liver, kidney, and heart. Holarmena antidysenterica showed some toxic effects on liver, kidney and heart but as compared to Caesalpinia bonduc the effects were mild.ThesisItem Open Access Integrated Nutrient Management In Maize-Wheat Cropping System(Birsa Agricultural University, Ranchi, 2001) Sushil Kumar Pathak; S.N.SinghOn going long term manurial trial started since 1983 at Birsa Agricultural University Farm, Kanke, Ranchi was selected for this experiment during two consecutive years of 1997-98 and 1998-99 to find out the effect of integrated nutrient management in maize-wheat cropping system, the most extensively adopted in the uplands of Chotanagpur plateau region. The soil of the experimental plot was Ultic-paleustalf, Red loam soil belonging to the Red-Yellow-Light-Grey Catenary Soil Association Group, representing major soil group of this region. The experiment was laid out in randomised block design with three replications. The treatments comprised of three organic sources viz. FYM, paddy straw and green karanj leaves (Pomganea pinnata) substituting 25 per cent and 50 per cent of the optimum doses of NPK during kharif season thus making six treatments, which were evaluated against four varying levels of inorganic fertilizers along with one each of unfertilized control and farmer's practice (only 50 kg Urea ha). The recommended dose of NPK for both maize and wheat were 100:50:25 kg N:PO, KO ha. At the inception of the experiment during 1983, the soil was well drained, loam in texture having Bulk density (1.39 g cm), Mean weight diameter of soil aggregates (0.718 mm), pH (6.5), water holding capacity at 33 KPa (19.6%) and 1500 K Pa (11.3%), organic carbon (0.410 %), available N (255.0 kg ha ¹), available P (14.19 kg ha-¹) and available K (190.7 kg ha). After 14 years of experimentation it was found that FYM either substituting 50 per cent (T) or 25 per cent (T,) of recommended NPK dose of inorganic fertilizers in maize and getting 100 percent or 75 per cent NPK in wheat, respectively scored over all other treatments as regards yield, economics, energy efficiency and maintenance of soil health. These two treatments, T, and T, produced wheat equivalent yields of 71.37 and 68.94 q ha fetching net returns of Rs. 28,918-67 and Rs. 28,694-33 per hectare with a benefit:cost ratio of 1.37 and 1.45, respectively. As against this only Rs. 21,803-33 ha was realized from T₂, the treatment getting 100 per cent NPK to both maize and wheat through inorganic fertilizers. The mean maximum uptake of N, P and K was also higher in these two treatments receiving FYM in kharif. The quantities of NPK removed by the system were 207.85, 29.43, 210.41 kg ha' in the treatment substituting 50 per cent N (T) and 204.52, 27.98 and 201.62 kg ha in the treatment substituting FYM in lower proportion i.e. 25 per cent (T) Energy production as well as energy-use-efficiency by the system in these two FYM treated plots exhibited higher values as compared to other treatments but were statistically comparable to each other. The values of maximum energy output (1,14,197 and 2,84,089 MJ ha¹ by grain and total biomass, respectively) was recorded in T. (substitution of FYM in higher proportion while T, (lower substitution of FYM) recorded highest energy-use-efficiency (3.772 and 9.460 by grain and total biomass) and lowest value of specific energy (427.57 MJ ton"). The other organic sources (paddy straw and green karanj leaves) were not as effective as FYM, but, they had definite favourable impact on soil properties. Paddy straw induced development of the highest organic carbon content in soil and the karanj leaves were as effective as FYM in available N content in soil. Yield under these organic sources were comparable in case of maize and superior in case wheat at their higher substitution to T,, the treatment getting 100 per cent NPK in both crops through inorganic fertilizers. Soil fertility analysis viewed that there was considerable improvement in physical condition of soil by reducing bulk density and enhancing mean weight diameter of water stable aggregates as well as water holding capacity at both 33 K Pa (Field capacity) and 1500 K Pa (Permanent wilting point) besides maintaining soil pH by the organo-inorganic combinations (T, to T). Considerable build-up in organic carbon percentage as well as in available N, P and K was also noticed through integration of organic sources with inorganic fertilizers (T, to T.).ThesisItem Open Access Effect of different feed Additives as growth promoter under different management systems on Broiler Production(Birsa Agricultural University, Ranchi, 2001) Shobhamani Marandi; A.K.SrivastavaOn the basis of results obtained in the present investigation, the following conclusions were drawn: Commercial broiler production is more profitable under cage managemental system as compared to deep litter. Chicks should be reared during brooding period (0-14 days) on deep litter. After brooding period birds should be transferred to individual metallic cages for better growth, feed conversion efficiency and economic return per unit of investment. Vimeral as feed additives which resulted in better growth and feed conversion efficiency as compared to other feed additives under deep litter system of management should be preferred. Vimeral should be offered @ 5 ml/100 birds during brooding period (0-14 days) and thereafter @ 7 ml/100 birds upto 42 days of age. Livfit @ 5 ml/ 100 birds and Calvit,,@ 10 ml/ 100 birds should be given during brooding period. Livfit @ 10 ml/100 birds should be given from 15 to 28 days and thereafter @ 20 ml/100 birds till 42 days of age. Calvit,, should also be given @ 20 ml/100 birds from 15 to 42 days of age for better performance. Livfit with Calvit,, which resulted in faster growth, better feed conversion efficiency and return per unit of investment as compared to other feed additives under cage system of management should be preferred. As earlier growth is positively associated with final weight and daily gain during 0 to 42 days of age, attempt should be made to accelerate growth during early phase of life of birds. Attempt should be made to improve blood Hb and serum Ca to accelerate growth, since these parameters are positively associated with live weight. Attempt should also be made to keep SGOT level within the limit by giving feed additives for better growth as it is negatively associated with body weight of broilers. and to asses the genetic worth of the parental population of the inbreds derived from different population. These population was generated from not less than forty five genetically and geographically diverse germplasm collected from India. Pre-slaughter live weight might be considered as slaughter criterion due to its positive association with different carcass characteristics.
