Rumen enhancer feed additive BEWI-SPRAY® Omega

Supports fertility

Product overview
BEWI-SPRAY® Omega is a rumen-protected fat powder containing natural linseed oil, developed for dairy cows in early lactation. It combines rumen-stable fat with linseed oil to optimise the supply of essential fatty acids and increase the energy concentration of the ration without impairing rumen function.

The challenge
Dairy cows frequently show low expression of oestrus symptoms and reduced insemination success, often due to insufficient energy supply after calving. Rapid return to the oestrus cycle and a needs-based energy supply are crucial for optimal ovarian and follicle development.

Your benefits

• Highly concentrated for the production of concentrates and feed supplements
• Supports health and fertility in high-producing dairy cows
• Ensures supply of alpha-linolenic acid
• Suitable for GMO-free feeding (VLOG-verified)
• Available directly from the manufacturer

Our solution
BEWI-SPRAY® Omega delivers a targeted combination of rumen-stable fat and linseed oil to improve energy balance and essential fatty acid supply in early lactation.

• Rumen-stable fat increases energy density of the ration without affecting rumen function
• Linseed oil supplies alpha-linolenic acid
• Increases milk yield without reducing milk fat content
• Contributes to improved fertility

Application and dosage
Use to support energy balance and fertility in early lactation and during periods of high performance demand (e.g. post-calving or reduced oestrus behaviour).
Dosage: Add BEWI-SPRAY® Omega as a feed supplement at 200–500 g per cow per day.
