2. Farm – O – San Reviva – The orange energy boost to support the cows recovery after calving.

In the period before and during calving dairy cows don’t eat and drink in. The cow can lose large amounts of water and electrolytes with blood calcium levels decreasing. This can make the animal lethargic, causing a further reduction of dry matter intake (DMI).

The metabolic changes that occur around calving can lead to a significant drop in DMI. Therefore, encouraging DMI (appetite) after calving is essential for giving cows the best start in lactation by minimising metabolic disease and optimising milk production.

Farm-O-San Reviva is a highly palatable post-calving drink that should be given immediately after calving. Easy to make, Reviva requires hot water between 40-45 degrees which is easily supplied at the correct temperature by Calor’s Rinnai hot water solution.

The benefits of Reviva are;

  • Easy to digest source of energy.
  • Contains large amounts of energy and calcium.
  • Rehydrates and replenishes mineral loss in the cow quickly.
  • Increases blood calcium levels and DMI.
  • Increases uptake of calcium from the gut.
  • Enriched with a flavouring agent, making it highly palatable to cattle.

    In a recent trial of 440 cows, 222 were offered Farm-O-San Reviva and 218 were offered a competitor product. The graph below shows that 207 of the cows offered Reviva directly after calving accepted it in comparison to 145 cows taking to the competitor drink, a difference of over 30%.

3. Milkivit – more than just a milk replacer

Calf rearing is both demanding and satisfying but considered important to the overall health and performance of a herd.

High growth rates in the first weeks of life (800-1,000g/day) lead to increased milk production during the first and second lactation.

An animal’s productive potential as an adult is influenced by the growth achieved early in life, with the first two months of a calf’s live providing the opportunity to boost their lifetime performance.

  • Milkivit portfolio of products.

Milkivit from Trouw Nutrition provides farmers with a range of premium calf- rearing products to give their calves the best possible start and a lifetime of high milk production.

The Milkivit range of milk replacers, endorsed by Lifestart, is made with the highest-quality skimmed milk and whey powders – providing the perfect balance of nutrients to rear strong, healthy calves no matter what system you use.Milkivit Energizer ECM is the first in a range of Energized Calf Milk (ECM) products designed to revolutionise the way we feed calves. LifeStart science indicates that having higher energy levels and lower osmolality in milk replacers is overall beneficial.

Milkivit solutions benefit you and your herd with:

  • Higher daily weight gain during the rearing phase
  • Reduced mortality and increased resilience
  • Breeding and first calving 1 to 3 months earlier
  • Higher milk production by leveraging the calf’s genetic potential
  • Reduced replacement rate and increased longevity
