Jeremy Platt and the staff at Lea Hall Farm, Wimboldsley, Cheshire, are targeted on strong heifer efficiency to common 23 months at first calving.
Setting the foundations for that is good colostrum administration at beginning: calves are fed three litres of pasteurised colostrum throughout the first two hours.

After a second feed, calves then transfer to an computerized milk machine the place they’re fed 150g of skimmed milk powder/litre of water.

Calves are supplemented with ad-lib pellets from day one, alongside finely chopped straw ad-lib.
At 90 days calves are moved in batches of 25-30 to the youngstock unit at Lea Hall Farm.
Here, they transfer onto a complete combined ration (TMR) of grass silage, straw, half mix (24% crude protein) and half heifer rearer pellets (18% crude protein).
“The proportion of protein depends upon the grass silage,” says Mr Platt. “This yr, the mix is increased. We put a number of the nuts within the TMR and that has helped that food regimen transition. Gradually, calves transfer throughout to 100% mix.”
Once in calf, they’re turned out to graze. They are moved again inside and placed on a transition food regimen three weeks earlier than calving.
Calf and heifer well being
Good vaccination protocols are key to stopping any examine in progress. At seven days, calves are vaccinated in opposition to pneumonia, and a repeat dose is given at weaning.
Heifers additionally obtain ringworm, bovine viral diarrhoea, leptospirosis and infectious bovine rhinotracheitis vaccines.
Heifers are foot-bathed with formalin as soon as every week, which has introduced down general digital dermatitis within the herd.
Mr Platt says: “In a gaggle of 100 we would have seen one or two [cases], however it is extremely contagious, so we didn’t need to go away it unchecked.
“We stamped on it shortly and began foot-bathing weekly, and we don’t see any digital dermatitis in our heifers now.”

“You need to rear your heifers as effectively as attainable on the least expensive price. Rearing prices have principally gone up on the again of upper feed prices and labour.
“I’m hoping the expansion positive factors we make will counter that price. It’s nonetheless cheaper to rear them then function a flying herd, and we aren’t bringing in unknown ailments. Plus, you might have a pool of heifers to choose from.”
