Equimins Country Living Egg Shell Improver – 1kg Egg Shell Improver is pure dicalcium phosphate, produced from phosphate rock, with no animal products in it. What makes it useful is not the calcium alone but the ratio: Equimins supply calcium and phosphorus at 1.3:1, which is the proportion a bird can actually put to work laying down shell. It is a white, tasteless powder that goes straight onto the feed, and a 10ml measure is supplied in the tub. This is the 1kg size, which at half a measure per bird per day is a long run for a small flock. Performance & Benefits Supplies calcium and phosphorus in Equimins' stated optimum ratio of 1.3:1. Pure dicalcium phosphate from phosphate rock, with no animal products. White and tasteless, so it mixes into feed without birds turning away from it. Equimins say it promotes growth in livestock and poultry and helps guard against ailments such as rickets and anaemia. 1kg tub with a 10ml measure included — one level measure is 10g. Suitable For Laying hens producing thin or fragile shells. Ex-commercial and rescue hens rebuilding condition. Other livestock and small animals — Equimins publish rates for dogs and for smaller animals as well as poultry. A flock of a few birds, where the 500g tub would be gone in a season. Not a substitute for grit. Hens still need insoluble flint grit to grind feed in the gizzard, and free-choice oyster shell alongside a layers ration; this is a measured supplement, not either of those. Feeding Sprinkle a small amount onto the food. Poultry: approximately half a 10ml measure per bird per day. Average dog: one measure per day. Smaller animals: a quarter to half a measure per day. One level 10ml measure weighs 10g. Replace the lid after use and store the tub at 10–20°C. Composition & Analysis Composition: pure dicalcium phosphate, produced from phosphate rock.
