What is the pre-slaughter phase? The preslaughter phase is the last phase of the broiler chicken’s life before slaughter. This phase includes multiple steps: withdrawal of feed and water, catching, loading into transportation crates, and transportation by road, In some cases, chickens may be placed in lairage (waiting area)...
Just remember that chickens do not have AMYLASE in their saliva. So feed digestion is not immediately as other animal species. As an adult, they love to have GRIT on their CROP and many of the stone pieces will stay for days in there. So soluble calcium will be released at different concentrations each day. Calcium grit is usually provided at molt time rather than as calcium supplement. So regulation of GRIT intake from layers would take a few days to be constant....

Recent publications by Verhelle und Saremi (2024) and Westreicher-Kristen et al. (2025) reported broiler feeding experiments to evaluate the nutritional value of guanidinoacetic acid (GAA) in comparison to L-arginine (L-Arg). Basically, reported broiler performance responses are in agreement with expectations based on literature. However, the authors drew misleading conclusions on the efficacy of GAA. It is our objective to clarify this matter because both publications confirm high arginine...

1. Introduction Chickens represent the most widespread source of animal protein that is acceptable for nearly all communities, and, not surprisingly, the highly efficient commercial production of chickens is practised daily worldwide. However, chickens also represent a reservoir of zoonotic agents like Salmonella or Campylobacter. Chickens in commercial production are hatched from disinfected eggs in a clean hatchery environment, despite Gallus gallus being evolved to hatch in...
