Our range of



GlycoPass is a highly palatable energy source.

GlycoPass has been proven to increase fertility and conception rates as well as improving forage intakes and butterfat and protein levels. Glycopass is available in both liquid and meal form.

Available in 25kg bags.

We have been feeding GlycoPass for a few years now. It has improved conception rates and milk solids in our high-yielding herd.

GlycoPass is a source of rumen-protected glycerine. Glycerine is a great source of glucose for ruminants; however, a large amount of this glucose is degraded in the rumen and so it is not of any use to ruminant animals.

GlycoPass allows the majority of the glycerine to bypass the rumen and go straight to the small intestine where it will be available to start the glyconeogenesis pathway to be converted to glucose. This will then increase blood glucose levels, helping to improve performance.

Focusing on glucose supply during early lactation can reduce the mobilisation of body reserves and therefore reducing negative energy balances.

GlycoPass can be fed through compound feeds or blends, added to TMR’s, top dressed onto silage or fed through a liquid dispenser.

Testimonial / Case Study

Alan Porter a dairy farmer from Lisburn, County Down has recently introduced GlycoPass to his ration. He milks 250 Holstein cows with four A5 Lely robots, he calves cows all year round and his current rolling average is 9,700 litres/cow/year.

He recently invested in in increased cubicle numbers and feed space alongside the robots to increase cow comfort and health. Alongside Genus, fertility records are recorded on a three-week basis.

He states that, “Since feeding GlycoPass the results speak for themselves. Pregnancy rate for the six months previous to introducing it were 23%. For the six months after it has been 30%! This has been achieved by an increase in conception rates from an already healthy 38% to an impressive 46% during the same six-month period.”

“The cows were performing exceptionally well on the GlycoPass and our feed cost/litre decreased due to the average days-in-milk falling with improved fertility. Milk constituents have also improved over the same period due to improved forage intakes and overall rumen and cow health”.

Why use farmgate nutrition?

  • Improve intakes
  • Higher milk yields
  • Reduce body condition score losses
  • Greater reproductive efficiency
  • Lower levels of SARA
  • Heathier, more profitable cows
