Relationship between neonatal glutamine supplementation and amino acid profiles, protein synthesis in splanchnic tissues and the plasma metabolome in 5-day-old piglets with low birth weight

The incidence of low birthweight ( LBiW ) piglets, which show impaired growth compared to normal birthweight ( NBiW ) littermates, has increased with litter size. We previously reported that glutamine increased the bodyweight and plasma glutamine concentrations in LBiW piglets, w...

Dynamics of Kidney Calcium and Phosphorus Mineral Handling in Laying Hens During the Transition to Egg Production

ABSTRACT The transition from immature pullets to sexually mature female chickens is accompanied by pronounced structural and functional modifications. This is accompanied by coordinated changes in hormonal and metabolic pathways that primarily regulate reproduction, nutrient util...

Effects of variable incubation temperature during embryonic days 10–13 on leg muscle transcriptomics in day-old broiler and layer chicks

Abstract In chickens, secondary myogenesis occurs during embryonic days (ED) 10–13, which is a critical developmental window sensitive to incubation temperature as a key environmental factor. This study investigates transcriptional profiles in leg muscle of broiler (Ross 308; Ros...

Social cues on stone tools outweigh raw material properties in wild primates

1. Abstract The ability to select appropriate tool material enabled early hominins access to new resources and environments. The underlying mechanisms driving tool selection effectively remain unknown. Observations of extant primates have demonstrated strong selectivity for speci...
