Knewe®-Mg prebiotic.

Knowledge of nutrition for economy, welfare and environment

A Knewe® approach to animal nutrition, driving triple bottom line results.

A new feed supplement product from sustainable biofuel production that provides environmental benefit, enhances animal welfare, and boosts animal productivity.

Knewe®-Mg has a prebiotic effect in the rumen of cows, sheep, deer and other grazing animals, helping the rumen flora process forage more effectively so that a good deal more protein can be recovered for use by those flora.

Therefore, crude protein intake can be reduced while still maintaining microbial protein production. This leads to a significant reduction in urea excretion, and also leads to a substantial decrease in the amount of nitrogen passed to the hindgut and excreted in faeces (and reduction in faecal odour).

Knewe®-Mg also has significant welfare benefits through providing efficient magnesium and calcium nutrition and supporting immune function.

Knewe-Mg® for dairying

The economic benefits of Knewe®-Mg for dairying

~20% better feed utilisation leads to significant productivity gains (a gain of 1.3 MJ/kg of Metabolisable Energy). This may manifest in various ways, including:

  • Increase in milk solids.
  • Improved liveweight gain.
  • Improved feed protein utilisation.
  • Reduced replacement costs from fewer carryover cows, and fewer animals lost to milk fever, mastitis, calving issues.
  • Reduced health maintenance costs.

The economic benefits of Knewe®-Mg are considerable, but will vary from farm to farm. Knewe® has a proprietary calculator tool to help estimate benefits using farm-specific inputs.

The welfare benefits of Knewe®-Mg for dairying

  • Efficient mineral nutrition:
    • Improved animal disposition: less aggression and fewer injuries
  • Fewer milk fever cases, and easier calving
    • Better condition recovery after calving
  • More rapid commencement of lactation
    • Earlier resumption of oestrus and conditioning of the endometrium for implantation.

The environmental benefits of Knewe-Mg® for dairying

  • Lessened impact on the environment, and reduced greenhouse gas emissions
    • Nitrogen loss to the environment down 30%
  • Reduced methane output
    • Reduced animal waste per kg of milk solids produced
  • Assists with Farm Environment Plan compliance.

Knewe®-Mg usage

Knewe®-Mg is easily intergrated into an existing feeding programme.

Knewe®-Mg is fed in pelleted form. Knewe®-Mg can be integrated with, and will enhance, any other nutrition formulation. Knewe®-Mg will comprise ~2% of of a dairy cow’s diet.

Knewe®-Mg’s ability to enhance protein utilisation means the amount of protein in the formulation can and should be reduced. In a conventional dairy diet, Knewe®-Mg enables the recovery of at least 50g more nitrogen per day, meaning it is possible to reduce daily crude protein intake by at least 300g. A proportion of the forage in the diet can be replaced by low-nitrogen supplements such as cereal straw and molasses.

Monitoring metabolism of excess protein for energy through milk urea concentration (either on an animal-by-animal basis, or at bulk milk level) can confirm the potential crude protein reduction.

Some of the benefits of Knewe®-Mg may not become apparent until the product has been used for ~8 weeks or more.

​Knewe®-Mg for beef farming

Economic benefits

  • Better feed utilization: productivity gains. Outcomes may include:
  • Up to 30% faster weight gain
  • Reduced finishing time by up to 25%
  • Increased meat yield by up to 5%
  • Improved meat quality (1 to 2 Wagyu score points).

Welfare benefits

  • Better maintenance of body condition throughout growth and development
  • Less aggression, fewer injuries
  • Improved immune performance (from yeast components).

Environmental benefits

  • Improved dietary protein utilisation reduces nitrogen excretion;
  • Improved dietary fibre utilisation reduces methane emissions;
  • Reduced faecal volume and odour.

​Knewe®-Mg for sheep farming (wool, meat, milk)

Economic benefits

  • Better feed utilization

Welfare benefits

  • Enhanced body condition after weaning, prior to mating – enhances twinning.
  • Reduced risk of milk fever and reduced risk of metritis.

Environmental benefits

  • Improved dietary protein utilisation reduces nitrogen excretion;
  • Improved dietary fibre utilisation reduces methane emissions;
  • Reduced faecal volume and odour.

Knewe®-Mg for deer farming (venison, velvet, milk)

Economic benefits

  • Better feed utilisation
  • Maximal calcium acquisition leads to better antler-production potential
  • Best possible velvet growth.

Welfare benefits

  • Reduced risk of milk fever
  • Earlier oestrus in dams
  • Fawns fed by dams receiving Knewe®-Mg grow significantly faster
  • Health status optimised by best immune support from yeast components, optimal metabolic energy status;
  • Reduced aggression improves handling, risk of injury.

Environmental benefits

  • Reduced nitrogen loss to the environment
  • Reduced methane output

How is Knewe®-Mg produced:

Knewe®-Mg is manufactured under licence by Lantmännen Agroetanol AB, the Swedish Farmers’ Cooperative, for Knewe Biosystems NZ Ltd.

Knewe®-Mg is made from fermentation products by a patented process, in which the acidic components are reacted with nutritionally-important minerals. This process makes the fermentation products shelf- stable, and the minerals much more bioavailable.
