Nutrimaize 46 (Regulated Protein Release)

Nutrimaize 46 is a sweet black liquid high in both Sugars and Protein which is based on a blend of pure cane molasses and bonded urea. Ideal as a dietary Protein Supplement for maize silage or other low protein forages it also increases Intakes and helps to improve Milk Quality. The bonded urea element in the liquid gives a phased release of energy and protein for Better Rumen Utilisation.

How does Nutrimaize work

Nutrimaize has been developed for use as a major supplier of ERDP in dairy diets based mostly on maize silage or other low protein forages. It combines the ease and cost effectiveness of a liquid feed with the high nutrient density required in modern dairy diets.

The protein contained in NutriMaize is derived mainly from Bonded Urea. This is manufactured by a unique process which involves the bonding of urea to individual glucose molecules. This greatly increases the resistance to enzyme attack, thus avoiding the sudden, excessive release of ammonia associated with non-bonded urea.

Bonded Urea is broken down slowly enough for the rumen microbes to make use of it. Therefore a phased release of nutrients is achieved which provides rumen microbes with a steady supply of both protein (ERDP) and energy (FME) to manufacture microbial protein for the cow's use.

Ideal as a maize balancer or for diets based on whole crop wheat. The high nutrient density of Nutrimaize 46 is designed to make it perfect for very high yielding cows. This allows sufficient nutrients to be supplied in a relatively small volume. This unique process of bonding together molecules of sugar and urea gives a phased release of energy and protein sources for rumen microbes to utilise.

To provide full flexibility on-farm NutriMaize is available as either a 28, 46 or 66% protein liquid.

The bonding process

The process of bonding requires a source of sugar as a base, making cane molasses the natural choice. The urea is added and bonds to glucose molecules using a precise combination of heat, time and acidity. The mix is then normalised leaving Bonded Urea in stable form in the liquid.

Trial Work

Nutrimaize has been evaluated on a number of commercial farms with great success. At Rodbaston College in Staffordshire, Nutrimaize 46 was introduced to the dairy cow diet as a 1:1 replacer for Rape/Soya. A feed rate of 2kg of Nutrimaize 46 via TMR was given which increased forage intakes, reduced feed costs and improved milk quality. Milk ureas were not increased with the introduction of Nutrimaize 46 confirming 'true' bonding of urea.
