Fibre-based feed supplements - fermentation and moisture characteristics, edibility and particle size influence cage-reared laying hens' preference based on feed consumption and time at the feeder.

1. Past studies have shown that fibre-based feed supplements, such as silage, are well accepted by laying hens and can reduce feather pecking and cannibalism. What is uncertain is whether fermentation and moisture characteristics, edibility or particle size influence the hen's choice for a fibre-based feed supplement or if there are more preferred materials.

Minimum light intensity threshold to prevent negative effects on broiler production and welfare.

1. Research focused on lower light intensity levels is required to set minimum standards appropriate for production and welfare of intensively housed broilers. The objective of this research was to study light intensity (0.
