Krishna; Venkataramanan, R.; Anilkumar, R.; Sreekumar, C.; Thangavel, K.; TANUVASVaccination is the process by which the response of an animal’s immune system to an infectious disease is stimulated by a method, other than developing and living through the disease. This process attempts to render the animal resistant to that disease upon future exposure. Historically, the vaccination process was an easy one. With the emergence of many new vaccines in the market and the realization that vaccination is not risk free, the process is no longer so simple (Rynders, 2005). The present paper discusses the different vaccines available for canines, their advantages, and regimen to be followed.ArticleItem Open Access Entropion in New Born Lambs(INTAS Polivet, 2009) Venkataramanan, R.; Selvan, P.; Anilkumar, R.; Krishnakumar, S.; Iyue, M.; TANUVASEntropion is a condition where the eyelid(s) are turned inwards causing irritation and abrasions to the surface of the eye. In the new born lamb this condition initiates severe keratitis and conjunctivitis, which if neglected can lead to corneal opacity, corneal ulceration, iris prolapse, suppurative panopthalmitis and sometimes even loss of eye. In case of bilateral affections this can cause complete blindness and death due to starvation. The present paper describes the diagnosis, treatment and correction of entropion in lambs.OtherItem Open Access Fertile Period in Crossbred Chicken(TANUVAS, Chennai, 2018-12) Prabhakar, R.; Priyadharshini, M.; Anilkumar, R.; Thavasiappan, V.; Krishnakumar, S.; Prema, N.; TANUVASAn experiment was conducted in crossbred chicken to study the period of fertility after artificial insemination. Semen was collected two times a week by standard abdominal massage method in adult crossbred male. Immediately after the collection, semen was inseminated into three laying hens and eggs were collected after third day after the insemination. Eggs were collected continuously for fifteen days without further insemination.ThesisItem Open Access Genetic analysis of growth performance in farm-bred New Zealand White Rabbits(TANUVAS, Kattupakkam, 2015) Sakthivel, M.; TANUVAS; Balasubramanyam, D.; Gopi, H.; Kumarasamy, P.; Raja, A.; Anilkumar, R.The population of New Zealand White rabbits was evaluated for its genetic structure and growth performance. Data on pedigree information for 18 years (1995- 2012) and growth for 15 years (1998-2012), collected from records maintained at the Sheep Breeding Research Station, Sandynallah, The Nilgiris were utilized for the study. The different growth traits studied were body weights at weaning (W42), post- Weaning (W70) and marketing (W135) age and growth efficiency traits víz., average daily gain (ADG), relative growth rate (RGR) and Kleiber ratio (KR) estimated on a daily basis at different age intervals from weaning to marketing.ArticleItem Open Access Immunization against androstenedione to improve the reproductive efficiency in Nilagiri and Sandyno ewes(2021-12) Anilkumar, R.; Chandrahasan, C.; Selvaraju, M.; TANUVASHealthy Nilagiri (90) and Sandyno (90) ewes were selected and allotted to 3 treatment groups of 15 ewes each, viz. AF (Androstenedione immunogen full dose), AH (Androstenedione immunogen half dose) and CC (Control ewes). The experiment was carried out in main and off breeding seasons. The ewes from AF and AH groups were injected with 2 ml (full dose) and 1 ml (half dose) of androstenedione immunogen at 8 and 4 weeks respectively before the start of breeding season. Immunization of ewes against androstenedione had no significant effect on tupping and lambing percentage. The litter size at birth was significantly increased in AF (1.47±0.07) and in AH (1.40±0.07) groups. The litter size was highest in AF Sandyno ewes (1.60±0.09) and in AH Nilagiri ewes (1.43±0.11). The litter size for immunized group ewes was higher during main breeding season (1.40±0.04) than off breeding season (1.23±0.06). Nilagiri (1.31±0.05) and Sandyno (1.33±0.05) ewes had similar litter size at birth. The litter weight at birth and weaning were significantly higher in AF (3.95±0.13 and 13.89±0.61 kg) groups followed by AH (3.80±0.13 and 13.19±0.61 kg) and CC (3.18±0.13 and 10.89±0.66 kg) groups. The weaning percentage/ survivability were similar for all the treatment groups.ArticleItem Open Access Impact of Hogget Feeding on Growth and Reproductive Performance in Nilagiri and Sandyno ewes(Intas Pharmaceuticals Ltd., 2020-12) Anilkumar, R.; Prema, N.; Prabhakar, R.; TANUVASFifty ewe hoggets of Nilagiri and Sandyno breeds aged 10-11 months were allotted to two treatment groups to study the effect of level of concentrate feed on production, reproduction and life time lamb produced (LTLP). Hoggets from group I was supplemented with 300 grams of concentrate feed per day as against 150 grams of concentrate feed given to hoggets in group II. The effect of additional feeding is reflected in significantly higher growth rate, Average daily gain (ADG), overall weight gain and Mean greasy fleece yield in group I ewes of both Nilagiri and Sandyno ewes. Tupping and lambing percentage of group I ewes were significantly higher and was more pronounced in Sandyno ewes. However, this was compensated by significant (P<0.01) increase in litter size and twinning percentage in group I Nilagiri ewes. Ewes from Group I Nilagiri and Sandyno bred 122 and 194 days earlier and gave birth to their first lambs at 97 and 179 days earlier than group II ewes. Total weight of lambs weaned was 3.04 and 1.61 times higher in group I Sandyno and Nilagiri ewes. The average LTLP was higher in group I Nilagiri (5.50 vs. 4.00) and Sandyno (5.10 vs. 4.30) ewes surviving for five or more years. Feeding an additional quantity of feed to ewe hoggets improved the production, reproduction and life time lamb produced.ArticleItem Open Access Impact of Intensive Nutrition and Management on Growth Performances of Dorset Nilagiri Crossbreds lambs (Dorni)(Intas Pharmaceuticals Ltd., 2020-12) Anilkumar, R.; Krishnakumar, S.; Thavasiappan, V.; TANUVASSuitability of Dorset Nilagiri crossbred lambs for intensive system of management was evaluated. Thirty-six (36) Dorset Nilagiri crossbred lambs were randomly allotted to two groups of 18 lambs (9 ram and ewe lambs) each with group A under intensive and group B under semi intensive system of management. Lambs under intensive and semi intensive system of management were provided with 200 and 150 grams concentrate per day per animal from three to six months, 300 and 200 grams per day per animal from six to 12 months respectively. The Hogget, nine months and yearling weight (17.10±0.59, 23.99±0.68 and 27.83±0.63 vs. 14.51±0.59, 18.36±0.68 and 20.60±0.63 kg) were significantly higher (P<0.01) in group A lambs. Lambs from group A, had significantly (P<0.01) higher overall body weight gain and ADG (15.99±0.36 kg and 59.31±1.30 g) than lambs from group B (9.25±0.36 kg and 34.17±1.30 g). Among the three stages, the ADG highest during 6-9 months in Group A ewe lambs (87.17±4.76 g). Significant reduction in ADG was observed during 9-12 months. Wool yield was significantly higher in group A lambs.OtherItem Open Access Kikuyu Pasture Quality in Temperate Terrain of Nilgiris During September to December(TANUVAS, 2013-08) Sakthivel, P.C.; Prema, N.; Rajkumar, C. Paul Princely; Anilkumar, R.; Iyue, M.ArticleItem Open Access Management of Foot Rot in Lambs(INTAS Polivet, 2009) Thangavel, K.; Krishnakumar, S.; Prema, N.; Venkataramanan, R.; Anilkumar, R.; Iyue, M.; TANUVASA total of 155 cases of lambs with lameness were presented for treatment from January, 2009 to July, 2009 at an organized sheep farm. The affected lambs were segregated into four groups and different treatment regimens were assessed. Animals of group 1 were treated by hoof trimming and foot bath. Those of group II were administered Streptopenicillin, along with hoof trimming. For group III, hoof trimming, foot bath and Streptopenicillin were administered, while the animals of group IV were treated with a combination of hoof trimming, foot bath, Streptopenicillin and topical oxytetracycline. Significant difference (P<0.01) existed between treatments I, II and treatments III and IV. Among the treatments, it was found that animals of groups III and IV responded better (80.0 and 94.3 percent, respectively). The salient features of foot rot and different management options available for treatment and control of this condition are discussed.ArticleItem Open Access Nutritional Value And Suitability Of Carrot Whole Top as Green Fodder(TANUVAS, Chennai, 2015-01) Venkataramanan, R.; Gunasekaran, S.; Sreekumar, C.; Anilkumar, R.; Iyue, M.; TANUVASThe carrot tops had high crude protein (144 g/kg), calcium (24.3 g/kg) and phosphorus (7.7 g/kg), comparable to sun hemp (Crotalaria junctea), fodder berseem and oil cakes, respectively. Milk from animals fed with carrot tops were free from residues of organochlorine, carbamate and organophosphorus pesticides. Carrot tops are perishable in nature and hence were preserved as feed blocks to extend shelf life. The nutritional value and keeping quality of the blocks were also studied. The studies revealed that carrot whole tops can be a promising alternate source of green fodder, especially in hilly regions where there is a shortage of green fodder during winter.ArticleItem Open Access Plasma Protein - An Indicator of Nutritional Status and Herd Health in Ovines(Intas Pharmaceuticals Ltd., 2020-12) Krishnakumar, S.; Anilkumar, R.; Prema, N.; Prabhakar, R.; Thavasiappan, V.; TANUVASA total of thirty seven (37) sheep were selected and their plasma samples were collected and analyzed for plasma urea nitrogen, total protein, albumin and globulin in monsoon and summer season. Dung samples were also tested for Haemonchosis. The results showed that monsoons showed higher mortality with higher Hemonchus infectivity than summer season. Every one unit of blood urea nitrogen increased, 0.953 times mortality decreased. And every one unit of globulin increased, 0.0163 times of mortality decreased, because of higher antibody titer level by active infection/ immunization. Every one unit of albumin increased, 0.0004 times of mortality was decreased. Plasma protein estimation provides better insights into herd health investigations in ovine.ThesisItem Open Access POLYMORPHISM OF KERATIN - ASSOCIATED PROTEIN (KAP) 3.2 GENE AND ITS ASSOCIATION WITH WOOL TRAITS OF SANDYNO AND NILAGIRI BREEDS OF SHEEP(TANUVAS, Chennai, 2017) Bharathesree, R.; Murali, N.; Saravanan, R.; Anilkumar, R.; TANUVASKeratin Associated Protein was one of the major genes that influence the wool traits in sheep. Gene mapping studies of keratin proteins have identified some chromosomal regions which have significant association with various wool quality and production traits. Among all the classes of Keratin Associated Protein gene, KAP 3.2 and KAP 6.1 genes are found to be polymorphic having impact on wool characteristics.ThesisItem Open Access POSTPARTUM RESUMPTION OF OVARIAN CYCLICITY DURING TWO DIFFERENT LAMBING SEASONS AND ITS RELATIONSHIP WITH MELATONIN RECEPTOR IA GENE POLYMORPHISM IN NILAGIRI EWES(TANUVAS, Chennai, 2015) Promod, K.; TANUVAS; Kulasekar, K.; Asokan, S.A.; Anilkumar, R.; Subramanian, A.; Ravikumar, G.The present study was conducted to determine the ovarian changes and the association of MTNRIA gene polymorphism with the resumption of ovarian cycles during postpartum period and to assess the efficacy of Ovsynch protocol for ovulatíon synchronisation during main lambing season (MLS) and second lambing season (SLS) in Nilagiri ewes.ArticleItem Open Access Soil Fertility of Grasslands under Influence of Grazing(2012-12) Venkataramanan, R.; Krishnakumar, S.; Sreekumar, C.; Anilkumar, R.; Iyue, M.; TANUVASGrazing is one of the important biotic factors that influences the formation and sustenance of grasslands.
