What is the most viable way to finish Pantanal lambs?

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 →

How cropping systems affect soybean yield?

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 →

Research tests ideal temperature for encapsulation of probiotics

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.

Research studies effects of grazing methods on the composition of the forage mass of a grassland

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.

Review brings together key topics on blackleg in cattle

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.

Membranes can be used to recover whey proteins?

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 →

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 effects of enzymatic hydrolysis on different collagens

The use of ultrasound concomitant to the enzymatic hydrolysis potentiates the structural breakdown of collagen. This was one of the results obtained by the study carried out by researchers from the Federal University of Santa Maria, Brazil, who evaluated the effects of assisted enzymatic hydrolysis with or without ultrasound on the functional properties of hydrolysates of different collagens.

Study evaluates tolerance of soybean genotypes to Asian rust

Several soybean genotypes tested were tolerant of Asian soybean rust, with relatively high grain productivity level. These were the results of a study carried out by researchers from the Department of Genetics of the University of Agriculture Luiz de Queiroz/USP, Piracicaba campus, São Paulo, Brazil Read More →
