The present study describes the genotypic distribution of rotaviruses (RVs) in an Indian bovine population with unexpectedly higher proportions of G3 alone or in combination of G8/G10. PCR-genotyping confirmed that 39.4% (13/33) of the prevalent RVs were the G3 type while 60.6% (20/33) were dual G3G10 or G3G8 types. P typing revealed that 93.9% (31/33) of the samples were P[11] while 6.1% (2/33) possessed a dual P[1]P[11] type. Sequence analysis of the VP7 gene from G3 strains viz. B-46, 0970, and BR-133 showed that these strains had sequence identities of 90.5% to 100% with other bovine G3 strains. The highest identity (98.9% to 100%) was observed with RUBV3 bovine G3 strains from eastern India. The G3 strains (B-46, 0970, and BR-133) showed 97.5% to 98.8% sequence homologies with the Indian equine RV strain Erv-80. Phylogenetic analysis demonstrated that G3 strains clustered with bovine RUBV3 and J-63, and equine Erv-80 G3. Overall, these results confirmed that the incidence of infection by RVs with the G3 genotype and mixed genotypes in the bovine population was higher than previously predicted. This finding reinforces the importance of constantly monitoring circulating viral strains with the G3 genotype in future surveillance studies.

Chicken (Gallus gallus), duck (Anas platyrhynchos), turkey (Meleagris gallopavo), guinea fowl (Numida meleagris) and quail (Coturnix japonica) are the common poultry species consumed as meat throughout the world. In this work, a molecular technique has been developed for identification and differentiation of meat originating from these species. This tool helps in detection of misrepresentation of different poultry meats. The technique involves the extraction of DNA from the given sample, polymerase chain reaction (PCR) amplification of mitochondrial 12S rRNA gene using universal primers, restriction analysis with selected restriction enzymes, followed by identification of meat species based on restriction fragment length polymorphism (RFLP) pattern. In this study, we used HinfI, Mph1 103I, MvaI, and Eco47I to identify and differentiate to poultry species referred to above. This species identification technique has also been applied successfully to processed meat products including those cooked at 120 degrees C for 30 min. Simplicity of interpretation of results combined with versatility makes this a convenient and appropriate technique in the hands of meat analysts for identifying poultry meat species.

The change in the total livestock population over past 3 livestock censuses is depicted below: CattleThe total cattle population is 9.59 million numbers in the state. There is a 14.50% decrease in number of cattle during the inter census period (2007)(2008)(2009)(2010)(2011)(2012).The above graph shows that the total exotic/crossbreed cattle population has increased from 1.10 million in 2003 to 2.39millionin census-2012. The indigenous cattle population has decreased from 8.19 million in 2003 to 7.19 million in 2012.The exotic/crossbred and indigenous cattle population has shown percentage changes of 26.34% and -22.81% respectively during the inter censuses period (2007-2012).
