Poultry Health

Crushed and graded limestone products are an important component of a feed regime for poultry flocks. Graymont supplies several grades of quality grits and finely ground materials suitable for layers, broilers and breeders from various supply points across Graymont.


A number of factors should be taken into account when selecting a suitable limestone product such as bird species, life stage, feed delivery system and the calcium content of seasonal or standard feed regimes.
