Milk yields get a boost from Actisaf®

"Last year we saved money on blend because the quality of forage was better and cows are performing so well on the diet"
    Adding probiotic yeast to the diet at Hare Appletree Farm has helped farmer, Andrew Metcalfe, improve milk yields whilst achieving more milk from forage.

    Andrew farms in partnership with his mother, Christina, and father, John, on a 250-acre traditional mixed hill farm in Quernmore, Lancaster. The farm has a herd of 85 cows and flock of 450 sheep, both of which graze the farm’s traditional pastures. The herd is mostly made up of British Friesians, which suit the farm’s system and location – some 400 metres above sea level with stony, heavy, clay soils. The herd calves all-year-around and replacements are reared on the farm.

    Andrew started working with Mark Gorst from Advanced Nutrition in September 2014 and in April the following year, as the cows went out to grass, Mark suggested adding Rumisaf, which contains Actisaf premium probiotic yeast, to the cows’ diet. “When we started working with Mark our average yield was 7,500 litres per year,” explained Andrew. “I knew we could be doing better – I only had to look around at other farms in our area to see that. It was a case of getting some help to get to where we wanted to be.”

    One of the main limitations on the farm is having to use the same fields for the sheep and lambs, as well as for the cows and silage. “It’s a balancing act,” explained Andrew. “We can only take two silage cuts as there isn’t enough time to do three by the time we’ve lambed and can move the sheep off the grazing land and on to the moorland, so we focus on getting the best quality from those two cuts,” said Andrew. Quality of grass is also a limiting factor and Andrew is in the process of reseeding some areas of the farm.

    After starting to work with Advanced Nutrition, the cows were put on to what Mark describes as a “relatively straightforward” ration. They are buffer fed a TMR of grass silage, chopped straw and blend, along with Rumisaf and minerals from Advanced Nutrition. “I recommend Rumisaf to farmers where we need to gain control of the rumen,” said Mark. “In Andrew’s case we introduced it when the cows were turned out to grass to ensure a good transition, we have left Rumisaf in the diet and since then we have never seen any issues when cows are brought back in, or when silage changes, which would typically be times when rumen function is challenged.”

    Following the introduction of the new approach to feeding, milk yields have risen steadily and now stand at 9,000 litres/year with butterfat at 4.2 per cent and protein at 3.2 per cent. “Importantly for us, 3,000 of our litres are from forage and, since introducing Rumisaf  into the diet, litres from forage have increased by around 800,” said Andrew. While this improvement can’t all be attributed to the addition of yeast, Andrew feels it certainly played a role alongside better forages.

    “Last year we saved money on blend because the quality of forage was better and cows are performing so well on the diet,” said Andrew. “The results speak for themselves, we were at 7,500 litres/year and we’re now at 9,000. The cows are healthy and look well, we don’t see any rumen upsets and we have seen the improvements in yield – the new approach works well and I’m pleased with the response from Rumisaf,” he concluded.
