Hen Nutrition and Welfare - Laying Performance

How hen nutrition affects welfare, covering calcium metabolism, gut health, and nutritional deficiency conditions.

Key Facts

Laying hens require 4.5-5g calcium daily for eggshell formation, substantially more than non-laying birds
Calcium deficiency causes medullary bone depletion and osteoporosis, increasing fracture risk
Access to insoluble grit improves gizzard function and feed utilisation in laying hens
High-producing hybrid strains are at greater nutritional stress than lower-yielding traditional breeds
Nutritional enrichment through varied foraging materials supports gut health and behavioural welfare simultaneously
