1 INTRODUCTION During the last decades, the productivity of laying hens has improved significantly, with higher number of eggs produced over the laying cycle and higher efficiency to utilize feed nutrients. This increase in productivity implies in a change in the requirements, and consequently, these hens become more demanding in nutrients, mainly amino acids (Elliot, 2008). Optimization of protein supply by understanding the amino acid needs of these hens requires a thorough...
INTRODUCTION Dietary amino acids (AA) and crude protein (CP) have been demonstrated to affect BW, body composition, organ development, and feathering in broiler breeder pullets (Hudson et al., 2000; Ekmay, 2011; van Emous et al., 2013). Breeder pullets are fed to achieve target BW, and meeting growth objectives during the rearing phase has been related to improvements in reproductive parameters such as fertility, hatchability, and embryo mortality (Leeson and Summers, 2000;...

Botanicals represent a wide class of complex compounds that naturally contain active principles with numerous biological functions. Among them, the anti-inflammatory and antioxidant actions are of key interest to support intestinal health during stressful phases. The aim of this study was to investigate the ability of a thymol-based blend of botanicals (BOT) to protect intestinal Caco-2 cells from the damages induced by an inflammatory challenge in vitro. Caco-2 cells were differentiated on...
INTRODUCTION Aflatoxin Testing in Changing Times: The Context at a Glance As toxic contaminants of very high concern, aflatoxins stand out as a key area of focus in today’s food safety testing arena. The issues surrounding the rising importance of accurate, defensible aflatoxin test results are numerous and complex. Chief among them are a growing public awareness of the health and economic implications of foodborne toxins, the increasing...
