Getting an of a heifer calf's potential as quickly as possible is the key to getting the best return from the investment in replacements. 

"While heifers are the lifeblood of your business and the future of your milking herd, they represent a significant investment and you need to maximise the return, which means only rearing the very best," comments Rob Horn, technical sales specialist at . 

"Each heifer reared to calve in at two years old is going to cost around £1,700-£2000.  This is why it is crucial you only rear the best quality calves which will grow into efficient and profitable dairy cows. But how do you identify the calves worth investing in?   

"The simple answer is by having the best quality and independent data to inform your decision-making," says Rob.  

Key knowledge  

can provide all the information you need from a single tissue which will tell you the genomic makeup of the heifer and crucially whether she is clear of BVD.   

"The genomic data tell you everything about her future capabilities, while the BVD status will ensure you only rear heifers that will grow to their potential." 

This not only provides dual perspectives from a singular sample but also delivers cost savings, time efficiency, and contributes to the overall enhancement of herd biosecurity.  

Your sample will undergo processing at the company's Ayr-based laboratory, ensuring that both BVD and Genomic results are obtained from a unified location, streamlining the information gathering process for your convenience. 

Samples are first tested for BVD status and only samples from calves identified as BVD negative will then be genomically tested.  These results, which are evaluated according to the AHDB standards, are back on farm in a matter of days ensuring rapid turnaround and full taceability throughout the process. 

Cow performance  

Genomics can help you can predict how well a cow will perform and how it compares to the other animals in your herd at a glance. This lets you see the best, rank your animals, and puts you in greater control of your herd. 

If the calf is you will know not to invest in her, saving the rearing costs and allowing labour to be focussed on BVD negative animals.  Then the Igenity genomics results give you an accurate picture of how well BVD negative animals will perform by looking at around 50 traits including production and management. 

By identifying your best animals and confirming they are BVD free, Rob says it is possible to maximise the rate of herd improvement, only breeding from the best genetics and ensuring the sires selected will improve the traits you need to improve. 

aims to help you understand the data's implications for your herd. Igenity data is independent from semen sales and not tied to a semen supply contract, which allows you to have unrestricted access to the widest selection of sires ensuring you can make the best breeding decisions for the future of your business.  

"Getting the most comprehensive data on heifer calves gives the power to reduce uncertainty when selecting heifer replacements, maximising the return on investment in heifer rearing while improving the rate of genetic gain."
