Lemongrass may be considered an interesting alternative to obtain extracts rich in bioactive compounds, with antioxidant activity and antimicrobial capacity. This was the conclusion of a study on the extraction of bioactive compounds from lemongrass (Cymbopogon citratus), carried out by researchers from the Federal University of Santa Maria. … Read More →

Small doses of a mexican weed plant called Cosmos bipinnatus are able to reduce enteric methane emissions from dairy cattle. This is the conclusion of a study conducted by researchers from the Universidad Autónoma del Estado de Mexico, in Toluca City, the Universidad de Colima, in Tecoman, Colima, Mexico, and the Molina Center for Energy and the Environment, in La Jolla, California, United States of America. … Read More →

The evaluation of the normalized difference vegetation index (NDVI) carried out by active optical canopy sensor can be used for the nitrogen fertilization in a varied dose in wheat, allowing the adjustment and variation of the nitrogen rate applied in different parts of the field. … Read More →

The finishing systems of pantaneiro lambs in feedlot and semi-feedlot are economically viable activities, since they allow the remuneration of all the factors of production and the invested capital. The internal rates of return of these types of termination are 27% for feedlot systems and 16% for semi-feedlot systems. … Read More →

Cropping systems had more than 50% incidence of soybean root rot. Among them, the pasture-soybean-pasture system is the least indicated to be applied in succession to soybean cultivation. The higher compaction of the soil and predisposition to root rot of soybean, caused by the application of the system, caused a loss of 23 kg per hectare of soybean for each 1% in the increase of root rot. These results were collected by researchers from the State University of Santa Catarina (UDESC), in Lages, Santa Catarina, Brazil. … Read More →

The air inlet temperature of 130°C in the spray dryer provided greater encapsulation efficiency of the microparticles Lactobacillus acidophillus La-5 and Bifidobacterium Bb-12. In addition, this temperature also made the physicochemical characteristics more desirable in these particles, such as low water activity and humidity, which ensure better microbiological stability. … Read More →

What changes in composition present the vegetation and forage mass of the remaining native areas of the Brazilian Pampa biome during winter? This question mobilized researchers from the Federal University of Santa Maria (UFSM), in Santa Maria, Brazil, to conduct a study on the effects of grazing methods on the composition of the forage mass of a natural pasture in the interior of Rio Grande do Sul. … Read More →

What are the main virulence factors of the agent of symptomatic carbuncle in cattle Clostridium chauvoei? How is the circulation of this pathogen? What are the main measures of disease control? Trying to answer these questions, researchers from the Federal University of Santa Maria, in Santa Maria, Rio Grande do Sul state, Brazil, conducted a literature review on the main topics about symptomatic carbuncle in cattle. … Read More →

With this study it was possible to recover 80% whey proteins using membrane of 10 kDa. These proteins showed good protein solubility, emulsion stability, and most were identified as β-lactoglobulin (18.3kDa) and α-lactalbumin (14.2kDa). Therefore, the use of membranes is an alternative to recover whey proteins in the industrial process. … Read More →

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 →
