Short-term gains in calf rearing could mean long-term losses

Producers are advised not to be tempted to cut corners in calf nutrition to save costs.

“The consequences of this can be long lasting,” says Cargill’s calf and heifer specialist Bianca Theeruth.

 

“Maintaining target growth rates in calves and youngstock is like achieving high interest rates – it is the herd investment,” says Ms Theeruth. “I appreciate, with volatile and falling milk prices, why producers might look to shave costs from the milk powder of creep feed bill and use a cheaper option but this will soon be reflected in growth rates.”

 

Less expensive and lower-spec calf milk replacers or creep feeds can look appealing for producers contemplating their cash flow, but it is often a false economy. “The danger here is it is just short-term gain. At the end of the month, the balance sheet may look slightly better, but remember this is a long-term investment and there will be a price to pay in the longer term. Lower growth rates can affect age at calving and this has been shown to impact on lifetime productivity.”

 

Increasing the age at first calving from 24 to 28 months can cost about £160 per heifer in feed costs alone and a recent Belgian study showed animals which calved at 24.6 months had 3.85 lactations compared with three lactations for those calving at 27.9 months, and 34 more productive days during their life than the older calving heifers.

 

“While the natural reaction to any squeeze on income is to try to reduce costs, the money spent on youngstock is vital and an important financial investment – not a luxury.”

Keeping calves and heifers on target

  • Heifers need to be gaining 0.75-0.8kg/day from milk feeding phase up to calving
  • The key rules are to ensure plenty of quality colostrum is fed, starting soon after birth, providing a high quality milk replacer through a reliable feeding system and giving calves solid feed of high quality from three days old to help rumen development and prevent growth rate checks
  • Calves should have access to fresh clean water
  • Post-weaning, heifers need fresh grazing and drier forage with concentrates offered to help to stabilise intakes and performance
