BioStart CALF

The level of rennet activity that causes the milk to clot (curd) in the newborn calf is highly variable. Weak curd formation is frequently seen in young calves and can be corrected by the addition of rennet to milk.

BioStart CALF is a concentrated rennet enzyme additive which turns colostrum or milk into a firm curd in the abomasum – the critical phase of casein digestion. This slows the milk’s passage through the digestive tract which aids digestion of all milk nutrients. BioStart CALF ensures milk digestion efficiency from day one.

  • Concentrated rennet enzyme additive
  • Aids milk clot formation in the abomasum
