Zolcal-D provides the ageing layer with an adequate supply of calcium and vitamin D to assist with keeping optimal health alongside improving shell quality, it may not stop shells becoming thin altogether as this is a partially natural occurrence.

Chicken Vet recommends Zolcal-D for use in hybrid laying hens over 50 weeks of age and for rehomed ex-commercial layers at any time. Zolcal-D is also suitable for rare breed layers during and after their second season of laying.

Zolcal-D is a veterinary formulated liquid supplement to be administered in fresh clean drinking water. It provides supplementary dietary calcium and vitamin D. Vitamin D promotes the absorption of calcium in the gut, maintaining calcium and phosphate concentrations in the blood, which enable normal mineralisation of bone. Some of the calcium is used from the hen’s bones which is processed into calcium carbonate which assists in shell formation. This can make layers in later life susceptible to osteoporosis (brittle and poor bone density) and the shell of the egg becomes thinner if they do not receive an adequate supply.
