Feed Additives


A highly-proven, rumen protected bypass fat, Megalac™ is a source of energy to support body condition, fertility and production. Megalac™ is a calcium salt of palm fatty acids.  

Feeding Recommendations

Feed between 0.2 to 0.5 kg/c/d.

The product is available in blends. Also available direct to farm in 25 kg bags (1 tonne minimum delivery) or 800 kg bulk bags (1.6 tonne minimum delivery).

Note: Consult your milk supply company for FEI guidelines


Megalac™ is a rumen-protected fat supplement which increases energy supply in diets without increasing the acid load in the rumen and risk of acidosiss, unlike starchy sources of energy such as cereals.

Megalac™ is an ideal supplement to increase energy supply in early lactation diets of cows and sheep and is well-proven to improve cow fertility.

Cattle Feed Storage on Farm

As with any grain or meal feed products need to be kept dry as moisture combined with heat can cause fungi to grow. Common on farm storage methods are: in a shed or unused fertiliser bin; in a covered pit; on a concrete pad; or in a cutting, covered with plastic sheet and tyres. Most feed should be used reasonably expediently (within 40 - 50 days). The longer you plan to store feed products the better your storage facilities need to be.
