ArticleItem Open Access Bargur Cattle : Characterization and Management Practices(Indian Vet. J., 2013-11) Ganapathi, P.; Rajendran, R.; Subramanian, A.; Meenakshisundaram, S.; TANUVASBargur cattle are generally red with white patches on the body. The extent of white patches varied among animals. The coat colour also varied from cherry red to light red. Muzzle and eye lashes were mostly brown. In majority of adults, the horn took backward, forward and upward direction. Hooves were brown in colour. In adult bulls, bullocks and cows, height at withers, body length and chest girth were 119, 114 and 119; 126, 126 and 139; 116, 115 and 124 cm respectively.OtherItem Open Access Carcass Characteristics and Sensory Quality of Synthetic Multi Colour Broiler (Nandanam B3) Developed for Backyard Poultry Rearing(TANUVAS, 2014-12) Kanagaraju, P.; Omprakash, A.V.; Babu, M.; Sanglimadan, K.; Balasubramanyam, D.; Rajendran, R.; Prabakaran, R.; Thyagarajan, D.OtherItem Open Access Carcass Traits and Sensory Quality of Nandanam Broilers-II Developed for Backyard Poultry Rearing(TANUVAS, 2014-12) Omprakash, A.V.; Kanagaraju, P.; Babu, M.; Sanglimadan, K.; Balasubramanyam, D.; Rajendran, R.; Prabakaran, R.; Thyagarajan, D.ArticleItem Open Access A Case Report on Rare Presentation of Multiple Uterine Torsions in a Wistar Albino Rat(TANUVAS, Chennai, 2021-07) Jalantha, P.; Rajendran, R.; TANUVASUterine torsion is twisting of uterus or its horn perpendicular to its long axis. This is a case report of uterine torsion in an adult Wistar Albino breeder. The rat was in advanced stage of gestation with no overt signs of illness. The rat was found dead with distended abdomen and four dead pups beside her in her cage. On post mortem examination, 270o uterine torsion was observed in left uterine horn in between the two dead foetuses present and there was a 360º torsion between the caudal foetus and the cervix. One dead fetus was observed in right uterine horn. Uterine torsion in this case was attributed to the foetus-maternal disproportion. Occlusion of uterine blood vessels leads to extensive uterine damage and consequent sequestration of blood to uterus might have resulted in hypovolemic shock and death of the rat. Being a rare condition in rats, uterine torsion should always be considered as a complication in parturition.ArticleItem Open Access Chromosomal characterization of Umblachery breed of cattle (Bos indicus) – a famous South Indian breed of Tamilnadu, India(Informatics Publishing Limited, 2008-11) Kumarasamy, P.; Sivaselvam, S.N.; Rajendran, R.; Thangaraju, P.; Nainar, A. Mahalinga; TANUVASUmblachery breed is an excellent draught cattle of Tamilnadu, noted for its strength and sturdiness especially used in the marshy fields for wed ploughing. Several genetic markers have been used for identification of farm animals. The present study was undertaken to characterize the Umblachery breed with chromosomes. The diploid chromosome number in Umblachery cattle was 2n=60 comprising of 29 pairs of autosomes and one pair of sex chromosomes. All autosomes are acrocentric, the X- chromosome is submetacentric and Y chromosome is acrocentric. C-banding in Umblachery cattle was showed all autosomes with darkly stained centromere but the sex chromosomes were found to be C-band negative.ArticleItem Open Access Comparative External Egg Quality Characteristics of Nandanam Chicken-II and Nandanam Chicken-IV Birds(Indian Veterinary Journal, 2016-02) Premavalli, K.; Rajendran, R.; Sangilimadan, K.; Kanagaraju, P.; Omprakash, A.V.; Thyagarajan, D.; Babu, M.; TANUVASA total of 60 fresh eggs comprising of thirty eggs each from Nandanam Chicken-II and Nandanam Chicken-IV birds reared under deep litter system of management was collected at 40th week of age and studied for its external egg quality characteristics. The overall mean egg weight, egg shape index, egg specific gravity and egg surface area were 52.98±0.48g, 75.90±0.62, 1.048±0.01 and 65.46±0.41 respectively. Non significant (P≥0.05) differences were observed in egg weight, shape index, specific gravity and egg surface area. It can be concluded that Nandanam Chicken-II and Nandanam Chicken-IV birds had comparable external egg quality characteristics.OtherItem Open Access Comparative Study on Hematological Profiles in Different Species of Poultry(TANUVAS, 2010) Pandian, C.; Thangapandiyan, M.; Sundaresan, A.; Rajendran, R.; Ashok, A.; Mani, K.OtherItem Open Access Detection of Lethal Mutation (A781G) in Growth Hormone Gene causing Early Embryonic Death in Vembur Sheep of Tamil Nadu(TANUVAS, 2014-12) Seevagan, M.; Jeichitra, V.; Rajendran, R.; Tirumurugaan, K.G.ArticleItem Open Access Detection of Lethal SNP (A781G) in Growth Hormone (GH) gene of Indian Sheep(Elsevier, 2015) Seevagan, M.; Jeichitra, V.; Rajendran, R.; Tirumurugaan, K.G.; TANUVASThe polymorphism of A781G locus of the growth hormone (GH) gene was analyzed in 112 Vembur sheep. HaeIII – RFLP of the GH gene (422 bp) revealed the existence of two genotypes viz., AA (366 and 56 bp) and AB (422, 366 and 56 bp), and two alleles viz., A and B. Genotypic frequencies for AA and AB were 0.43 and 0.57, and allelic frequencies were 0.71 and 0.29 for A and B respectively. BB genotype was absent. Highly significant Chi-square value (P < 0.001) showed that the population is not under Hardy–Weinberg equilibrium at the A781G locus. This indicates that molecular markers associated with embryonic survival are to be explored for their use in MAS in Vembur population.ArticleItem Open Access Distribution and Population Status of Bargur Cattle(Indian Veterinary Journal, 2009-09) Ganapathi, P.; Rajendran, R.; Subramanian, A.; TANUVASThe Bargur breed of cattle is primarily a hilly draught breed of Tamilnadu. Bargur cattle are medium sized animals. They are red coloured with varying extent of white markings. They are semi-wild and hardy to handle. The information of habitat, distribution and population status would help in decision making regarding conservation. Hence, the present study was taken up with the objective of getting information on distribution and population status of Bargur cattle.OtherItem Open Access Economics of Inclusion of Meat by Product - Ossein on Part Time Egg Production Performance in White Leghorn(TANUVAS, 2010) Pandian, C.; Sundaresan, A.; Rajendran, R.; Kumaravelu, N.; Mani, K.; Thyagarajan, D.ArticleItem Open Access EcoP151 வரைமுறைப்படுத்தும் நொதிகளின் மூலம் வேம்பூர் மற்றும் கீழக்கரிசல் செம்மறியாட்டினங்களில் வளர்ச்சி ஹார்மோன் மரபுக் காரணிகளின் பன்முகத்தன்மை அறிதல்(Veelan ariviyal tamil iyakkam, Newdelhi, 2016) Cheevagan, M.; Jeichitra, V.; Rajendran, R.; Ilavarasan, R.ArticleItem Open Access Effect of Egg Size on the Hatching Performance of Beltsville Small White Turkey(Indian Vet. J., 2013-09) Premavalli, K.; Babu, M.; Rajendran, R.; Omprakash, A.V.; Reetha, T. Lurthu; TANUVASThis study on effect of egg size on the hatching performance of Beltsville Small White turkey showed that the egg size had significant (P<0.05) effect on the hatching performance of Beltsville Small White turkey. Eggs weighing 71 – 75g had significantly (P<0.05) higher fertile hatchability (77.81%), numerically high total hatchability (65.04%) and significantly (P<0.05) low dead in germs (6.12%) and dead in shell (16.07%). It is concluded that medium sized Beltsville Small White turkey eggs weighing 71 to 85 g are optimum for obtaining good hatchability.OtherItem Open Access Effect of Egg Storage Period on Hatchability and Embryonic Mortality in Broiler Breeder(TANUVAS, 2010) Premavalli, K.; Thyagarajan, D.; Rajendran, R.; Babu, M.; Mani, K.ArticleItem Open Access Effect of Mating Ratio on the Hatching Performance of Guinea Fowl(Indian Veterinary Journal, 2013-05) Premavalli, K.; Rajendran, R.; Babu, M.; Omprakash, A.V.; TANUVASThe study showed that the mating ratio had significant effect on hatching performance of pearl guinea fowl. The birds with mating ratio of 1:4 and 1:5 had significantly (P<0.01) higher fertility (81.05, 75.89%), total hatchability (73.68, 62.50%) and fertile hatchability (90.91, 82.35%). Hence it is concluded that mating ratio of 1:4 and 1:5 may be optimum for guinea fowl birds reared under intensive system of management as they had good fertility, hatchability and low embryonic mortality.OtherItem Open Access Effect of Mating Ratio on the Hatching Performance of Guineafowl(TANUVAS, 2010) Premavalli, K.; Thyagarajan, D.; Prabakaran, R.; Rajendran, R.ArticleItem Open Access EFFECT OF NON-GENETIC FACTORS ON SURVIVABILITY IN MECHERI SHEEP(Indian Society for Sheep and Goat Production and Utilization, 2013-04) Jeichitra, V.; Rajendran, R.; Rahumathulla, P.S.; Karunanithi, K.; TANUVASData on 1763 records of Mecheri sheep at Mecheri Sheep Research Station, Pottaneri, Salem (Tamil Nadu) over a period of sixteen years (1991 to 2006) were analyzed for pre- and post-weaning survivability (0-3 months, 3-6 months and 6-12 months of age). The effects of various non-genetic factors viz., period of lambing, season of lambing and sex of lamb on survivability were analyzed. The least squares means for0- 3, 3-6 and 6-12 months survivability were 94.521063, 93.521067 and 92.46:0.80%, respectively. Period and season of lambing had significant (P<0.05 / P<0.01 ) effects on pre-weaning survivability. Post-weaning survivability was influenced in general by the period and season of lambing (P<0.01). Sex of lamb was a non-significant factor for the survivability except for 6-12 months survivability.ArticleItem Open Access EFFECT OF NONGENETIC FACTORS ON BIRTH WEIGHT, WEANING WEIGHT AND PREWEANING GAIN OF BARBARI GOAT(TANUVAS, 2009-05) Bharathidhasan, A.; Narayanan, Rita; Gopu, P.; Subramanian, A.; Prabakaran, R.; Rajendran, R.; TANUVASA study was conducted to analyse the effect of sex, season, type, parity and year of kidding on birth weight and weaning weight of Barbari goat. The average birth weight of male kids was 4.17 % higher than female kids. However, the average weaning weight of female kids at 3 months was 2.28 % higher than male kids. Birth weight of kids born during northeast monsoon and summer season were higher than southwest monsoon and winter seasons. Further, the weaning weight at southwest monsoon showed the highest value over weaning weights of other seasons. The birth weight and weaning weight of single born kids were of higher weight than twin birth kids. Birth weight of second parity was higher than first and third parity. The weaning weight and average pre weaning daily gain were also higher in second parity than first parity. Birth weight of kids born during year 2007 (1.98 ± 0.08 kgs) had higher values than year 2006 (1.85 ± 0.08 kgs) and year 2005 (1.81 ± 0.10 kgs). However, weight at 3 months had lower value during year 2007 (6.21 ± 0.51 kgs) than year 2006 (7.65 ± 0.47 kgs). The average daily gain was also more during year 2006 than year 2007. It was concluded that there was no significant effect of nongenetic factors on early production parameters of the Barbari goat.
