The impact of using tannin extract in cattle and sheep diet

Several cows grazing on a vast grassy field.

During the rearing of dairy cattle and sheep, the diets managed impact the composition of the milk produced, especially regarding fatty acids. Researchers evaluated the use of a condensed tannin in the fat profile of the milk of these animals and concluded that black acacia extract improves the nutritional quality of sheep’s milk, with no adverse impact on cattle.

The conversion of degraded pastures to forest legumes and soil depth promoted changes in the chemical composition of carbon. Through chemical carbon fractionation it is possible to detect in a fast and promising way soil chemical changes caused by land use and management techniques. Read More →

Water use in coconut crop can be more efficient during drought with deficit irrigation

Well-lit photo of a coconut tree with at least 10 coconuts on the tree and very wide leaves. On the ground, grass, soil, and two piles of coconuts (about 30 coconuts).

Sustained deficit irrigation can increase the efficiency of water use in dwarf coconut irrigation, but significantly reduces its productivity. The use of this technique is only economically justified in situations of restricted water supply for irrigation, as occurs during droughts in the Brazilian Northeast. Read More →
