Duarte Neves (Zinpro)      This study aims to evaluate shell translucency as a novel eggshell quality parameter to predict hatchability of fertile eggs. A total of 22,140 eggs were collected from 738 broiler breeder flocks between 25 to 65 wks of age, from multiple commercial hatcheries in the US. Translucency was completed with Zinpro® BlueBoxTM using a 3-point score syste ...

1. IntroductionThe use of a low-crude-protein diet fortified with essential amino acids is a part of a precision feeding and has gained commercial acceptance to improve protein utilization, minimize environmental impact and thus increase the sustainability of broiler production, because it reduces the cost of production [1–3]. Protein accounts for the second most expensive nutrient in poultr ...

INTRODUCTION Poultry needs protein for growth, egg production, immunity, enzymatic activity, tissue turnover, and much more (Beski et al., 2015). Similar to other essential amino acids (AA), supplemental branched-chain amino acids (BCAA) such as isoleucine and valine allow for a reduction in the crude protein (CP) in the diet, whereas leucine is generally found in higher amounts in the cornbased d ...
