Research ArticleOpen accessIn the abstractGenetic Characterization of a Bovine Breed (Tabapua) Under Artificial Selection Located in the Amazon RegionJose Elivalto Guimaraes Campelo, Marcone Helmer da Silva, Ednaldo da Silva Filho et al.Brazil currently has the biggest commercial bovine cattle population in the world. Several different breeds that come from Europe and India compose it. They are primarily used for dairy and meat production. In Brazil, several high quality genetic background cattle are kept in a condition known as pure breed, meaning no other animal of different genetic background is interbreeding with … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 30 Jan 2013 · 7,552 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy and Identification of Insulin-Like Growth Factor-I Gene Polymorphisms in Zel Sheep PopulationSeyed Mohsen Kazemi, Cyrus Amirinia, Hossein Emrani, Shahaboddin GharahveysiProblem statement: The IGFs play an important role in regulating somatic growth according to nutritional conditions. Polymorphisms of IGF gene are reported to be significantly associated with many traits. Approach: In these study 142 samples of DNA from Zel sheep were used for detecting the polymorphisms of promoter region of the Insulin-like Growth Factor-1 (IGF-1) gene. Therefore DNA extracted from … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 13 Jan 2012 · 7,739 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Polymorphism Exon 9-11 at the Leptin Gene Receptor in Breeder Hens of Mazandaran Native FowlsHossein Ali Abbasi, Shahabodin Gharavysi, Rohullah AbdullahpourProblem statement: Leptin a 16 kD protein synthesized by white adipose tissue and involved in regulation of feed intake, energy balance, fertility and immune function. In order to evaluate the leptin gene receptor polymorphism, we have used a Restriction Fragment Length Polymorphism (RFLP) method. Approach: Blood samples were collected from randomly chosen 100 native fowls breeding station of Mazandaran. The … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 17 Sep 2011 · 7,700 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacterization of Bovine Calpastatin Gene in Nelore Cattle Using Polymerase Chain Reaction-Restricted Fragment Length PolymorphismsAlireza Majidi, Jothi Malar Panandam, Awis Qurni Sazili, Siti Shapor SirajProblem statement: In beef cattle production, of meat quality and carcass traits are important. Traditionally beef cattle breeding programs unfortunately are time consuming and also recording of carcass and growth traits need heavy cost, Approach: Marker Assisted Selection (MAS) should be utilized in beef herds, along with economically important phenotypic traits, for genetic progress to made with respect to improving … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 7,329 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Diversity Analysis of the Gohilwari Breed of Indian Goat (Capra hircus) Using Microsatellite MarkersSubodh Kumar, S. P. Dixit, N. K. Verma et al.Problem statement: Gohilwari breed of goat is a multipurpose goat mainly for milk and meat purposes and best suited in its harsh climatic condition. This breed is inadequately characterized till now at DNA level. So the present study was undertaken for population genetic analysis at molecular level to exploit the breed for planning sustainable improvement, conservation and utilization, which subsequently … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,925 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMethylenetetrahydrofolate Reductase (MTHFR) from Mediterranean to Sub-Saharan AreasRosa Chillemi, Andrea Angius, Ivana Persico et al.There are differences in the allele frequency of MTHFR polymorphism between Western and African population. The aim of this study is to determinate the prevalence of MTHFR C677T and A1298C polymorphisms in young and old people living in different areas from Mediterranean to sub-Saharan areas. The observed vs expected genotype frequencies of 677T were in Hardy Weinberg equilibrium, with the … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 7,590 accessesView PDF Cite
