    “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.
