Multiple-trait genomic evaluation for milk yield and milk quality traits using genomic and phenotypic data in buffalo in Brazil

R. R. Aspilcueta-Borquis, Neto, F. R. Araujo, Santos, D. J. A., Hurtado-Lugo, N. A., Silva, J. A. V., and Tonhati, H., Multiple-trait genomic evaluation for milk yield and milk quality traits using genomic and phenotypic data in buffalo in Brazil, vol. 14, pp. 18009-18017, 2015.

The objective of this study was to compare the multi-trait model using pedigree information and a model using genomic information in addition to pedigree information. We used data from 5896 lactations of 2021 buffalo cows, of which 384 were genotyped using the Illumina Infinium® bovine HD BeadChip, considering seven traits related to milk yield (MY305), fat (FY305), protein (PY305), and lactose (LY305), percentages of fat (%F) and protein (%P), and somatic cell score (SCS).

Detection of Salmonella Enteritidis in asymptomatic carrier animals: comparison of quantitative real-time PCR and bacteriological culture methods

B. M. Maciel, Dias, J. C. T., Romano, C. C., Sriranganathan, N., Brendel, M., and Rezende, R. P., Detection of Salmonella Enteritidis in asymptomatic carrier animals: comparison of quantitative real-time PCR and bacteriological culture methods, vol. 10, pp. 2578-2588, 2011.

Quantification of Salmonella in asymptomatic carrier animals can be used to assess microbial risk and monitor the level of contamination in domestic animals used for food production. We examined the sensitivity, specificity and accuracy of real-time qPCR, without pre-enrichment or selective enrichment stages, for the quantification of S. enterica serovar Enteritidis in resistant mice, as a model of asymptomatic carrier animal. The results were compared with those obtained by traditional bacteriological culture methods, the gold standard test.
