Kingshay Dairy Costings Focus Report 2021

Kingshay's Dairy Costings Focus Report 2021 shows big herd health improvements, with dairy herd health and fertility seeing some marked improvements over the past year.

Looking at all of the main health incidences recorded in Kingshay Health Manager – from milk fever to difficult calvings - every one has dropped, year-on-year, which is a great result.

  • Mastitis cases have dropped from 36 cases per 100 cows last year to 32 this year – down from 41 in 2017.
  • Lameness has followed a similar downward trend, from 43 cases per 100 cows in 2017 to 36 this year, likely due to increased culling for lameness and the use of mobility scoring, routine foot trimming and footbathing.
  • Fertility has improved, too; despite the calving interval remaining unchanged at 397 days, cows required fewer services per conception and culling for infertility fell from 7.9% to 6.7%, year-on-year. That means infertility costs have dropped by 13%, to £176/cow.

What does this mean?

As a result of this improved herd health, farmers have managed to slash antibiotic use, from 21.6mg/kg PCU in 2018 to 16.1mg/kg PCU this year. This year 77% of herds were below the RUMA target of 21mg/kg, with the amount of critically important antibiotics used down from 1.5mg/kg PCU in 2018 to 0.39mg/kg PCU now. “This is a fantastic result and shows the efforts which vets and producers have made to protect these important antimicrobials for human medicine,” says Kathryn Rowland, senior farm services manager at Kingshay.

When it comes to production and financial performance, there are some equally encouraging trends. Based on actual figures from over 1,250 herds with 250,000 cows across the UK, yields and milk solids reached a record high this year across all types of production system, averaging 8,512 litres/cow and 638kg/cow, respectively. However, with higher input costs margins have taken a hit, particularly given the impact of the COVID-19 lockdown on milk prices last year. On average, the margin over purchased feed eased back from 20.44p/litre or £1,720/cow last year to 20.16p/litre and £1,716/cow this year (year ending March 2021).

When comparing the different production systems, organic producers once again topped the table in terms of margin over purchased feed (MOPF), both on a per litre and per cow basis. While no one system is right for all, the figures provide producers an opportunity to benchmark against similar farms and identify potential areas for improvement.

“Encouragingly, the bottom quartile of producers have managed to really narrow the gap on the top 25% across every type of system, showing that attention to detail and incremental gains remain key to success,” says Mrs Rowland.

For the first time this year, Kingshay produced figures for crossbreed herds, as well as Channel Island and organic, all of whom are making tremendous use of forage. “Over all herds, yields from forage have consistently increased over the past three years, although concentrate usage has also risen across the board to support higher yields,” she explains.
