ThesisItem Open Access Studies on Mite Infection in Dog and Its Control with Special Reference to Demodicosis(Birsa Agricultural University, Ranchi, 1997) Manoj Kumar Jha; Dr.A.R.DebThe sarcoptes scabiei infestation was observed more 41 (19.09%) whereas Demodex canis was less 21(6.70%) different breeds of dogs. The mite infestation was recorded highest (27.36) in 6-12 months of age group as compared to other age groups. The males were more susceptible (21.83%) to the mites infestation than females (17.26%). Further study revealed that infestation was more common during winter season (22.95%) as compared to other seasons. Dogs reared under good management condition, the occurrence of infestation was less (15.38%). The localised infection of demodicosis was observed more (4.15%) than generalized condition (2.55%). Hematological study in experimentally infected pups revealed lower value of hemoglobin concentration and packed cell volume whereas differential leucocyte count showed lymphocytosis and eosinophilia. The biochemical profiles study indicated the increase in the value of globulin where as decrease in cholesterol, total lipid and albumin was observed.ThesisItem Open Access Studies on the Performance Of Different Cultivars Of Kagzi Lime (Citrus aurantifalia Swingle)And Their Reaction To Bacterial Canker(Birsa Agricultural University, Ranchi, 1996) Rajeev Kumar; C.SinghIn this investigation, detailed observation were recorded on the tree growth, fruit yield fruit quality and tolerance to canker. The salient finding of the trial are summarized as under: 1.The maximum tree vigour as manifested by tree height, girth and canopy was obtained on Nepali Kagzi closely followed by Banarasi and Madrasi and minimum tree vigour was recorded in seedling lime (hight 148.67cm , girth 15 cm and canopy 123.33 cm3). 2. Banarasi recorded the highest number of shoot (9.67) per square metre followed by Madrasi (9.50).Lowest number of shoot was noted a seedling lime. Similar trend was observed in case of number of leaves per square metre. 3.Banarasi was observed to attain the highest percentage of fruit set(60.67%) followed by Madrasi in seedling lime (27.67%) . Lowest fruit set was found in seedling lime (27.67%) 4. Baranasi Topped the list in respect of yield in Kologram as well as in number of fruits per plant (416.00,13.50 Kg per plant ) followed by Madrasi (374.33, 11.60 kg per plant ) and lowest yield was noted on seedling lime (126.33,3.36 Kg per plant) 5.Weight of ten fruits was maximum in Nepali Kagzi (550g) followed by Banarasi (325g) and Madrasi (315g). Minimum fruit weight was found in seedling lime (230.33g).ThesisItem Open Access Studies on the Prevalence Of Eimeria Species Infection In Fowls And Control Of Caecal Coccidiosis In Broiler Chicks(Birsa Agricultural University, Ranchi, 1995) Santoshi Toppo; R.N.P.SinhaThe feed conversion ratio was found to be narrower in m = 100 and AV/CCP/12 medicated groups and still narrow ratio was observed in AV/CCP/12 treated control group. Feed consumption was found to be higher in AV/CCP/12 treated control group but the feed consumption was found to vary slightly in both the drugs treated and infected control, Body weight gain was found to be more in AV/CCP/12 treated infected and control. groups of birde before and after infection. On the basis of the parameters recorded during 14 days observation in respect of prepatent period, clinical symptoms, OPG feed consumption, body weight gain, it was found that 25x10³ viable oocysts challenge infection was well tolerated by both the drugs treated birds. Typical histopathological changes were observed in infected control groups whereas the degree of histological alteration were less in the drug treated birds.ThesisItem Open Access Studies on The Incidence of Haemoprotozoa And Control Of Theileria Annulata Infection In Cattle Of Chhotanagpur, Bihar(Birsa Agricultural University, Ranchi, 1993) Anil Kumar Singh; Dr.K.D.PrasadIt was observed that SBTRA-LD administered o 1 ml/20 kg body weight intravenously for 5 days could help in recovering only 50 per cent treated animals. The recovered animals rather remained weak, anemic and carrier of the infection till 15 days post treatment. Thus the drug was found unsuitable in during clinical T. annulated infection in calves. The GO-LABHA was observed to cure all the four treated animal when given 1 ml/kg body weight orally for 10 days. The drug was found to eliminate the protozoa from the circulation till 25th day post-infection and treatment along with regain in haemograms and normal body temperature without any apparent adverse effects. Thus, the drug was found to be satisfactory in the treatment of theileriasia in calves. However, the drug should be tried on large number of experimental and natural clinical cases before being advocated to use in field conditions.ThesisItem Open Access Studies On Eimeria Tenella Infection In Poultry With Special Reference To Incidence And Immunoprophylaxis(Birsa Agricultural University, Ranchi, 1989) Deb, Asit Ranjan; B. N. sahaiOut of 1,200 poultry intestines examined, 228 intestines were found positive for tenella infection. The age-wise incidence revealed the highest (35.78 %) occurrence of infection in 0-3 months followed by 16,46 and 4.09 par cent in 3-6 and above 6 months age groups, respectively. The seasonal incidence indicated that 29.75, 16.25 and 11.00 per cent birds were infected with E. tanelle during monsoon, winter and summer seasons, respectively. It was also observed that the birds reared under intensive and free-range systems of management harboured 23.45 and 7.05 per cent infection. Thus, it was concluded that terella infection is common in age group 0-3 months in monsoon season under intensive manage mental condition. LETENSITY OF EINERIA ZENELLA INFECTION The moderate to intense infection of tonella vas observed in the birds of both 0-3 and 3-6 months age groups. There was non-significant (P>0.05) difference in the intensity of infection during monsoon, winter and summer seasons. Where as under intensive system of management moderate (+) intensities of infection was more (52.68 %) than that of other grades. But there was non-significant (P>0.05) difference of intensities under free-range system of management.ThesisItem Open Access Studies On Epidemiology, Host-Parasite Relationship And Immunity To Coccidial Infection In Goats(Birsa Agricultural University, Ranchi, 1989) Sinha, Rai Nandan Prasad; B.N. SahaiThe present study was undertaken to ascertain the incidence and intensity of coccidial infections in goats, their transmission in sheep and vice-versa, host-parasite relationship, chemoprophylactic control of experimental coccidiosis in kids alongwith attempt to immunize passively against the mixed coccidial infections in kids by immune serum transfer experiment. Incidence: The incidence of coccidia in goats in and around Ranchi was found to be 46.06 per cent after examining 1380 faecal samples and 157 intestinal scrapings of goats. The seasonal incidence of coccidia in goats indicated 64.62 and 50.29 per cent infections in rainy season under farm and village conditions, respectively. The incidence was highest in rainy season as compared to summer and winter seasons, which was statistically significant (P < 0.01). The coccidial infections in male and female goats were found to be 46.95 and 44.65 per cent respectively, which was statistically non-significant (P>0.05). The four breeds viz., Jamunapari, Beetal, Black Bengal and cross breds, under farm conditions did not show any impact on the incidence of coccidia. It was also statistically non-significant (P>0.05). The present investigation revealed highest incidence of 69.54 and 62.03 per cent in goats under six months of age in farm and village management conditions respectively.ThesisItem Open Access Studies On Pathology, Transmissibility And Chemotherapy Of Manage Infestation In Rabbits(Birsa Agricultural University, Ranchi, 1988) Bhattacharyya Debasis; A. BasuIn the present study, clinical manifestation and gross pathology of body coat were observed in both natural and experimentally infected rabbits at weekly interval upto 56 days post-infection. The incubation period was also observed in both groups of animals. In natural infection, the incubation period was 13 days, whereas, in artificial infection this period was seen to be 25 days. The site of onset of lesion, in natural infection group, was over the nose, whereas in experimentally infected cases the lesion started from the base of the ears, after which the spread of lesion was more or less similar in both groups. During first two weeks pei. the lesion was restricted on the facial region of the body. From third week onward, the lesions were seen on other parts of the body e.g. paws of hind and fore legs and external genitalia of both male and female. There were scab formation, alopecia and wrinkling of skin with dull, depressed and emaciated condition of the animals. On examination of the skin scraping, intensity of infection was found to be maximum at seventh and eighth week P.i. in artificially infected group (++++) and eighth week p.i. in naturally infected group (****).ThesisItem Open Access Studies On Some Aspects Of Experimental Infection Of Toxocara canis LARVAE In ALBINO MICE(Birsa Agricultural University, Ranchi, 1988) Samanta Subhamoy; M. Z. AnsariStudies on the prevalence of Toxocara canis in dogs in and around Ranchi, on the basis of faecal examination revealed that of 197 faecal samples 42 (21.32 were positive for infection. The infection rate was higher 38.03 % (27 of 71) in 'stray dogs than 11.91 % (15 of 126) in 'owved dogs. In both stray' and 'omned' groups of dogs the infection rate was higher in young dogs of less than 1 year (1) age (47.17 % and 24.49 %) and lower in those above 1 year (1) age (11.11 % and 3.89 %) , respectively. On sacrifice of T. canis positive pups, the mean vorm burden vas 10.4 worms/pup and the ratio between male and female worms was almost equal (1.08 : 1). Temperature had profound effect on the embryo nation of T. canes eggs. Eggs kept in cultures reached the infective stage in 32-39 days at 17°C and 12 - 14 days at 27°c. Egg cultures maintained at 37°c disintegrated before reaching the infective stage. The average measurement of unembryonated eggs vas 86.2 by 75.6 , embryonated eggs 86.7 by 77.7 and second stage larvae, recovered from visceral organs, 352.8 by 20.3. Larval recoveries were maximum of 76.8 % in liver on day 2, 22.4 % in lungs and 11.1 % in kidney on day 5, 3.7 % in spleen and 2.7 % in eye on day 10, 57.3 % in skeletal muscles on day 15 and 40.1 % in brain on day 30 post-infection.ThesisItem Open Access Incidence OF Infection in Domestic Animals And Its Control In Mice And Buffaloes(Birsa Agricultural University, Ranchi, 1988) Laha, Ramgopal; K.D PrasadThe present investigation was conducted on "Incidence of Trypanosoma evansi infection in domestic animals and its control in mice and buffaloes to know the status of the protozoa in cattle, buffaloes and goats in and around Ranchi by blood and spleen smears examination alongwith biological test. For developing an effective chemotherapeutic and prophylactic control against the infection in aice and buffaloes, TRIBEXIN Prosalt (IDPL, Hyderabad) was tried in a single S/C dose a 6,66 mg/kg but. The effectiveness of the drug was evaluated on the basis of criteria taken into account. The overall incidence of evansi in cattle and buffaloes revealed 22 (3.17 %) cattle and 12 (2.69 %) buffaloes out of 693 and 446 animals tested, respectively were harboring the organism during the year of examination. But the seasonal incidence of the infection indicated that 4.32, 4.29 and 0.76 per cent cattle were positive for the protozoa during summer, rainy and winter seasons, respectively. The infection rate in buffaloes during summer, rainy and winter seasons were 3.30, 4.29 and 0.61 per cent, respectively. None of the goats tested were found carrier of the protozoa. When the infected mice were therapeutically treated with the drug it cured the mice from the acute infection within 24 hours PF whereas the pretreated mice did not allow the parasites to establish in thes. Further observations showed that the infected mice regained the normal values of DLC, Hb and PCV shortly after treatment. But the treated and subsequently
