LIMESTONE GRANULAR 2-3MM is very rich in calcium for poultry and fish. It is much used as an additive to animal feed. Normally they mixed about 5% for animal feed. It is a good input material for all feed mills. Besides the calcium content, many feed mills also concern on the content of magnesium oxide and iron oxide because it is hazardous metal for the animal.
The limestone for feed is exploited from our Yen Bai mining with high quality and whiteness.
