The color of soybean seeds influences its quality

The premature ripening of soybeans can produce greenish seeds, directly affecting the quality of the lots. Observing this, researchers from the Federal University of Pelotas (UFPel) and the University of Passo Fundo (UPF), evaluated the influence of the presence of green soybean seeds on the physiological quality of soybean seed lots.

Innovative method measures chlorophyll content in millet leaves

Responsible for the green color of plants, chlorophyll is an essential indicator in monitoring plant nutrients during their growth. Traditional methods for measuring chlorophyll, in addition to taking a long time, damage the leaves. Alternatively, a model based on hyperspectral images was developed to detect the chlorophyll content in millet leaves. Read More →

Study tests the effects of different preservatives for milk

Milk producing establishments must send milk samples monthly to laboratories accredited by the Federal Government of Brazil. The preservation of these milk samples requires the addition of preservatives, such as sodium azide and coranphenicol, and different amounts of these components have different effects on the conservation of milk.

Influence of cattle feed on the quality of beef in Uruguay

Uruguay has beef production as one of its most important economic activities. The quality of this meat can be affected by peculiarities of the animals’ production system, such as their food for example. The Longissimus Dorsi muscle, when tested in three different food systems, also showed differences in its quality. Read More →

Did you know it is possible to determine the soil quality through infrared?

Infrared methods are often used in science. To determine the quality of soil fertilization, clay and soil organic matter (MOS) are essential components. For the analysis of these components, the use of the analytical technique of near infrared spectroscopy (Near Infrared Spectroscopy – NIRS) presents a sustainable alternative. Read More →

How to preserve the health of farm tractor operators?

The vibration produced by tractor operation has negative effects on the health of the operators of these agricultural machines. To evaluate the transmissibility of vibrations, a research presents an innovative method that allows to observe the influence of tractor-coupled agricultural equipment on the operator’s whole body vibrations.

Can Dachshund dogs develop retrobulbar meningioma?

A study of a female Dachshund breed with altered neurological signs resulted in a diagnosis of multifocal lesion. At necropsy, it was found to be a rare tumor in the retrobulbar region, affecting only 3% of dogs. The research draws attention to the importance of including this possibility of pathology during diagnosis. Read More →

Scientist-tested methods enhance fiber properties

The capacity of dietary fibers to improve digestion and metabolism is directly linked to the physico-chemical properties of these elements, such as water retention capacity, oil binding and fiber cations. The research found that it is possible to improve the functional characteristics of the fibers, through methods such as micronisation and extrusion. Read More →
