Genetic traits in cattle worth over £360 per head

The British Limousin Cattle Society has released research indicating that genetic traits in cattle can be worth in excess of £360 per animal.

Genetic Traits – Key Results

£150 per animal – Bettering carcass quality

£96 per animal – Improving feed efficiency

£79 per animal – Lowering days until slaughter

£42 per animal per annum – Higher Fertility

 

Alison Glasgow, Technical Manager, Limousin Cattle Society

Three main studies have been carried out with genetic traits in Limousin Cattle being the focus:

Genetic Traits Study #1

– Video image analysis to ID quality of carcass of 6 prime cuts over 20,000 cattle.

– These results were put together with data from the British Cattle Movement Service on crossbred animals and pedigree information with the aim of producing Genomic Estimated Breeding Values.

– Extra value of all 6 prime cuts combined showed that there was a difference of up to £150 per animal.

– Results showed that differences of up to 2KG were noted even on animals of the same grade and carcass weight for striploin cuts.

 

Genetic Traits Study #2

– More work has been done on economic performance attributes e.g. fertility, slaughter (age) and feed efficiency.

– Results displayed a 44-day difference between the top 1% and bottom 1% for cattle to finish.

– The society went further than just pedigree animals with their genetic traits data and also looked at crossbred cattle data via the British Cattle Movement Service.

– The results revealed that Limousin cattle had the following against the next best breed:

  • 5% less heifer replacement rate
  • 2% greater longevity
  • 1% less calf mortality rate

 

Genetic Traits Study #3

– Research into intake and food conversion rates to produce a Genomic Estimated Breeding Value is currently in process and is around 50% complete with 800 animals tested so far.

– The results currently show that when feed is more efficiently used on animals it saves around £96 per animal.

 

Ms Glasgow stated:

“A rough estimate using finishing costs of £1.80/day means the difference is £79 per animal.”

“Getting replacement rates down can save £42 a cow a year.”

 

Genetic Improvement of Cows in the UK

– It is estimated that there is a £4.9 million per year area of profit for farmers in the area of genetic improvement.

– There is a heavy focus on maternal trait recording and this is setting a baseline for further developments in the future.

– Genetic engineering progress has been continuing to rise in the UK and has made a huge impact on the potential to increase progress rates.

 

Genomics

– Genomics looks at the function, structure and mapping of Genomics and DNA, in this case, in the beef industry.

– The results of Genomics are vital for developing and producing more effective vaccines for cattle. These vaccines not only prevent disease but they help the cow’s immune system develop extra antibodies for use against future diseases

– SNP (Single Nucleotide Polymorphism) technology is the most used for genomic testing in cattle.

– Genomics has helped a lot in regards to beef traceability and if food was to be recalled it’s exact origin can be traced if genomic has been involved along the way
