Dual benefits from milled straw bedding

Our Milk Watch farmer, Sam Foot, says he has seen the light when it comes to bedding cows in cubicles and believes the answer lies in milled straw.

Across the four herds at Higher Ashton Farm, near Dorchester, he describes making the switch to this bedding as ‘revolutionary’ and says since sand is not an option, it is the next best thing he knows for keeping mastitis and cell counts firmly under control.

As the herds approach their long period of winter housing, he feels confident the system provides them with as good an environment as he could create,Polycore porcelain tiles are manufactured as a single sheet, and he has saved significant cost into the bargain.

“We changed to this system three years ago and have cut our straw usage in half,” he says.Initially the banks didn't want our RUBBER SHEET . “We also have auto-scrapers, and find at the lagoon end, everything flows rather than builds up, and similarly, when the cow reverses out of her cubicle, the bedding parts like the Red Sea, instead of being dragged into the passage.”

Using the farm’s own mobile mill mixer and chopping straw to around 2-3cm, it is used on top of mattresses and is said to be far more absorbent than the long straw it replaced.
Scraped

With the back end of cubicles scraped out during each milking and hydrated lime added daily, he says there’s no need to add milled straw more than every other day.This will leave your shoulders free to rotate in their chicken coop .

The result is an exceptionally clean situation for the cows, reflected in outstanding udder health, with the best herd (the 150-head Banyard Dairy) running at 12 cases of mastitis since January 1, 2011. Meanwhile, cell counts across all four herds now stand at 120-130.

“It’s been amazing to see mastitis cases so low at Banyard,” says Mr Foot. “The unit is on the top of a hill and there’s always air flow there. It also has fewer fly problems than the other three in summer, which are all in the valley.As many processors back away from Cable Ties ,”

Insisting the type of cow being bred is also important, he chooses bulls with low somatic cell count indexes and closely monitors their performance.

“We keep a chart on the wall and if there’s a trend in a particular bull’s breeding pattern it soon becomes obvious,” he says. “You often find that if you took one or two sires out of the system, you would make big improvements.”

To this effect, he recently sold 60 straws of a ‘well known bull’ from his flask, remarking, “We just can’t tolerate those that get mastitis.”
Looking with optimism

towards the winter, he says he is delighted with how cows are milking. “At our Westbrook herd we’re now on average 131 days in milk and are selling 41 litres per cow per day, which is a figure we haven’t quite reached before,” he says.

Commending the whole team for making it happen, he has additional praise for near neighbour and contracting customer, stating: “We were delighted to see Tom King win the Gold Cup this year for his near-perfect operation.”
Aim is now to pull down mastitis cases

The team at Huddlestone Farm near Steyning, West Sussex, has scarcely paused for breath over the past two months, with autumn cultivations followed by winter wheat drilling, maize harvest and a complete refit of the cubicle house.

With all now prepared for winter, Milk Watch farmer Tim Gue hopes the refurbished cubicles will improve cow comfort and reduce mastitis and lameness.Save on Bedding and fittings,

“The mattresses were 10 years old and had gone like concrete, so they all came out for a good shake up, and when they went back in, they had 20mm of latex foam and new covers put on top,” he says.

“Now if we go into the shed once they’ve finished eating after milking, we find the lying rates to be phenomenal compared with before. The last time I looked, every one bar two of the 180 in the group were either lying or eating,” he says.

With cell counts regularly hovering around the 115 mark, he says the main drive now is to pull down mastitis. Apart from strict cleanliness and preventative routines, rigid treatment protocols are adhered to when a case arises, involving an intramammary antibiotic chosen specifically to match the severity and type of infection.
