Poultry Science, 2017 The objective of this study was to compare the laying performance, egg quality, and serum biochemistry of hens maintained in conventional cage rearing system (CRS), flat net-rearing system (NRS), and free range system (FRS) under summer conditions. Indigenous Xianju chickens (n = 540) were randomly allocated into cages or pens of rearing system groups,

Safety and efficacy of Nutrase P (6‐phytase) for chickens for fattening, other poultry for fattening, reared for laying and ornamental birds [PDF]
EFSA Journal, 2020 Nutrase P is available in powder, granulated, thermostable granulate and liquid forms. It is based on a 6-phytase produced by a genetically modified strain of K. phaffii. The production strain contains four copies of the ampicillin resistance gene and one copy of a bleomycin resistance gene.

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space
Advanced Robotics Research, EarlyView.A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...
