Copper toxicity in broilers – a hidden effect?

ALESSANDRA MONTEIRO and STÉPHANE DUROSOY question if older meta-analyses and literature reviews on the use of copper as a growth promoter are still relevant, as some ingredients in old feed formulas could have interfered with the results. As an example, they focus on the interactions between copper and roxarsone.

Methionine application – spray accuracy and homogeneity

WILLIAM GOH, CLAIRE XU and KEVIN LIU compiled 86 lab reports from 22 feed mills across six countries in the Asia Pacific region, that clearly show both recovery and homogeneity of liquid OH-methionine are as reliable and consistent as the dry form of methionine.

Feed form affects apparent metabolizable energy of feed ingredients in broilers

MAHMOUD KHALIL, REZA ABDOLLAHI, FIFI ZAEFARIAN and RAVI RAVINDRAN investigate the impact of mash versus pelleted feed on energy evaluation of individual feed ingredients for broilers.

Variability in nutrient measurement of feed ingredients

AMY MOSS, PETER CHRYSTAL, TAMSYN CROWELY and GENE PESTI demonstrate that high variability in nutrient measurement of feed ingredients can drastically reduce the profitability of poultry production.

Using NIR technology to mitigate rising feed cost

LIHONG ZHANG AND KEVIN LIU present an update on the advancement of NIR calibrations, broiler trials to validate the prediction results, and possible applications to rapidly quantify the relative values of common ingredients.

Targeted application of enzymes reduces economic impact of COVID-19

DIEGO PARRA and JAE CHEOL KIM present how a maximum matrix nutrition strategy can extract the maximum possible nutrients from the diet while providing the highest profitability to help animal protein producers adapt to the COVID-19 new normal.
