    STUDIES ON EPIDEMIOLOGY, HOST PARASITE RELATIONSHIP, IMMUNITY AND CONTROL OF Eimeria spp. INFECTION IN FOWL (Gallus gallus) OF JHARKHAND
    (Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2013) Kishor, Birendra; Deb, A. R.
    The studies were conducted on the prevalence, immunization and therapeutic control of Eimeria species infections in fowls. The results obtained have been discussed earlier in detail, the same have been summarized as follows: 1. A total of 2100 faecal samples and 1490 intestinal samples from birds were examined during the present investigation and 1216 faecal samples (57.095%) and 687 intestinal scrapings (46.107%) were found positive for the Eimeria species infections. 2. The per cent prevalence of E. tenella (34.24 %), E. necatrix (10.34 %), E. acervulina (0.62%) and mixed infection with E. tenella + E. necatrix (4.91%), E. tenella + E. acervulina (3.09%), E. necatrix +E. acervulina (2.47%) and E. tenella + E. necatrix + E. acervulina (2.34%) were recorded. 3. The fowls of 0-3 months age were found highly susceptible to the different Eimeria species of infections on the basis of faecal sample and intestinal scraping examination. 4. The maximum prevalence of Eimeria spp. infection was recorded during monsoon season followed by winter and summer on the basis of faecal sample and intestinal scraping examination. 5. The haemato-biochemical observations showed decrease in haemoglobin and PCV values in infected untreated birds throughout the experimental studies. 6. TLC (%) values were also found increased in infected untreated birds throughout the experimental observations. 7. Lymphocytes (%) significantly found increased in during infection. 8. The marked monocyte (%) population was noted reduced and eosinophils (%) were seen to get increased in the infected untreated birds. 9. Whereas the basophiles (%) were found unchanged in all groups on different days of observations. 10. The neutrophils (%) significantly decreased in infected untreated birds. 11. The total serum protein (g/dL) was found decreased in infected untreated birds. 12. The AST (I.U/dL), ALT (I.U/dL) and the serum glucose (mg/dl) were noted to be significantly increased in infected untreated birds. 13. The x-ray irradiated 32(mAs) group and 12th passaged oocysts inoculated fowls had higher body weight gain. While the infected birds showed reduced body weight gain. 14. The oocyst Per Gram (OPG) was observed to be more in infected untreated birds while the lowest OPG count was observed in 32(mAs) x-ray irradiated oocysts inoculated birds. 15. The cent percent efficacy of neem leaf water extract and Amprolium hydrochloride treated were observed in infected treated birds. 16. The severe lesion score (++++) was observed in infected untreated fowls. 17. The high stimulation index (S.I) value was observed on 31th day in passaged oocysts inoculated fowls. 18. A distinct band of precipitation was observed in Agar Gel Precipitation Test in 12th Passaged birds.

    “STATUS AND CONTROL OF GASTROINTESTINAL HELMINTHS AND THEIR IMPACT ON THE ECONOMICS OF CHOTTANAGPURI SHEEP production”
    (Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2013) Jena, Anurag; Deb, A. R.
    The studies conducted on the status and control of gastrointestinal helminths and their impact on the economics of Chottanagpuri sheep production has been summarized and concluded as follows: SUMMARY 1. The overall prevalence of G.I. helminths in Chottanagpuri sheep at Ranchi and its localities was 62.55%. 2. The helminths identified were Paramphistomum Spp., Fasciola Spp., Moniezia Spp., Strongyloides Spp., Trichostrongylus Spp., Haemonchus Spp., Trichuris Spp., Oesophagostomum Spp., Ostertagia Spp. and Cooperia Spp. 3. The area-wise prevalence (Husir, Patratoli, RVC Sheep Unit, Bijalia, Agru, Chaildag, Hesal, Chandra, Mayapur, Kutatola and Obaria) of G.I. helminths in Chottanagpuri sheep showed that highest percentage of infection was recorded in Obaria (78.43%) and lowest in RVC Sheep Unit (32.14%). 4. Sex-wise prevalence of G.I. helminths in Chottanagpuri sheep indicated that females were having more (66.24%) infection than males (56.60%). 5. The age-wise prevalence of G.I. helminths in Chottanagpuri sheep showed that the sheep aged between 3-9 months were having 60.86% degree of infection while 0-3 months and above 9 months were having 66.14% and 53.50 % infection respectively. 6. The seasonal prevalence of G.I. helminths was significantly more in rainy (73.22%) than winter (60.73%) and summer (52.36%) seasons. 7. The Fenbendazole and Ivermectin were 100% effective against G.I. helminthiasis in growing lambs on 10th and 7th day post-treatment EPG observations. 8. The haematological studies (Hb, PCV & TEC) during G.I. helminthiasis and treatment indicated significant return Hb, PCV & TEC value towards normal while the infected animals had slightly decreased Hb, PCV & TEC values. 9. The average weekly body weight (Kg) gain in growing lambs during G.I. helminthiasis and simultaneous treatment indicated significant increase in body weight, where as the increased rate in weight gain of infected lambs was considerably lower. 10. Fenbendazole was also found to be 100% effective against G.I. helminths on 10th day post-treatment EPG observation in pregnant sheep. 11. There was significant improvement in Hb, PCV & TEC values of the pregnant sheep post-treatment. 12. Significantly higher body weight and growth rate up to weaning in lambs born of parasite free pregnant sheep were observed. 13. There was 27.27% mortality up to weaning in lambs born of parasitized pregnant sheep whereas 100% survival was observed in lambs born to parasite free pregnant sheep. 14. In growing lambs, there has been a net body weight gain of 23.15 kg between Fenbendazole treated group and control group, similarly a net body weight gain of 25.05 kg has been found between Ivermectin treated group and control group. 15. Net body weight gain of 28.40 kg has been found in between lambs born of parasite free and parasitized pregnant ewes. 16. Significant margin of profit viz. Rs.1084 and Rs.1158 approx. were obtained in both Fenbendazole and Ivermectin treated groups per each growing lamb respectively and similar, profit of Rs.1340 approx. was obtained up to weaning from the lambs born of parasite free pregnant sheep.
