Study genotypes southwestern Chinese wheat varieties

Through the genotyping of 138 samples, researchers mapped two groups of wheat varieties from southwestern China. Group I presented non-T6VS/6A1 lines from different origins, while group II presented T6VS/6A1 lines, most of which originated from Guizhou, China. The study, conducted by researchers at the Suranaree University of Technology in Thailand and the Guizhou Academy of Agricultural Sciences in China. Read More →

Research evaluates the microbiological quality of vacuum packed beef from Mato Grosso state in Brazil

Beef production in Mato Grosso follows satisfactory hygienic and sanitary conditions of the processing environment and final product. These were the conclusions of a study conducted by researchers from the Federal University of Mato Grosso, in Brazil, which evaluated refrigerated vacuum-packed beef produced by Mato Grosso state establishments holding Federal Inspection Service (SIF).

Research tests concentration of toxic metals in commercial yerba mate in the southern Brazilian states

The Yerba mate commercialized in the Brazilian states of Rio Grande do Sul, Paraná and Santa Catarina has a high concentration of cadmium metal, exceeding the limit established by the National Agency of Sanitary Surveillance (ANVISA). Even so, when used in hot infusions, yerba mate exhibits low concentrations of toxic metals such as arsenic, cadmium and lead. Read More →

Literature review covers supplementation of progestogens in pigs gestation

Although it has already been described for decades, the use of progestogens in manipulating swine gestation needs to be evaluated under current conditions of swine production. There are still few available scientific data on this technique and its commercial viability. Researchers from the Federal Universities of Pelotas, Santa Maria, and the state of Rio Grande do Sul have reached these conclusions from a literature review of studies on the manipulation of the childbirth of the female swine.

What are the factors that explain the voluntary adoption of beef cattle traceability at farm level?

The traceability of beef origin is a requirement for some import markets. Research results show that capital-intensive livestock production system, high scale production, access to specialized information and high level of social capital increase the probability of voluntary adoption of beef cattle traceability at farm level.
