ArticleItem Open Access Canine Parentage Verification Using Microsatellite Markers(Indian Veterinary Journal, 2018-09) Divisha, R.; TANUVASA study was designed to assess a panel of ten microsatellite markers to determine parentage in four representative pedigree breeds of dogs - the Dalmatian, Dachshund, Labrador Retriever and Shih-Tzu. The microsatellite loci of interest were amplified by polymerase chain reaction and the resulting augmented products were run on a genetic analyser. Allele sizes, analysed with the help of a gene mapping software, were measured and compared, to determine similarities between the progeny and their putative parents. Conclusively, the microsatellites were found to be a reliable molecular tool in parent- age analysis due to its uniform distribution throughout the genome.ArticleItem Open Access Echidnophaga gallinacea on country chicken (Aseel) in different agro climatic zones of Tamil Nadu and its control by using herbal preparation(2020) Soundararajan, C.; Prabhu, K.P.; Arulprakash, M.; Divisha, R.; Pandian, Serma Saravana; TANUVASPoultry fleas are known to cause severe irritation, anemia, blindness and death in chicken. A total of 2580 country chicken (Aseel) from 12 villages of six districts and three agro-climatic zones in Tamil Nadu, India were examined for flea infestation from April 2019 to March 2020. The collected fleas were identified as Echidnophaga gallinacea. The overall prevalence of flea infestation in country chicken was 25.54% with western zone alone having 40.80% which was significantly (P< 0.01) higher than the north eastern and hill zones. The infestation was comparatively more in adult birds than chicks. Three different preparations were used to control the fleas in country chicken: a 1% Deltamethrin solution, ground Acorus calamus (Vasambu) powder made into a paste with coconut oil and Psidium guajava (common guava) leaf extracts. The preparations deltamethrin, vasambu paste and guava leaf extracts controlled flea infestation in the chicken after 2nd, 4th and 5th day of application, respectively.ArticleItem Open Access Future challenges and Strategies to overcome in Indian Poultry Industry(2016-08) Prakash, M.
