FERTILITY FOCUS AT ROYAL HIGHLAND SHOW
Herd monitoring technology improves conception rates through accurate heat detection and optimised insemination timing.
With the use of sexed semen to breed replacement heifers and accelerate the genetic progression of dairy and beef herds becoming increasing commonplace, Allflex Livestock Intelligence’s focus at this year’s Royal Highland Show (Ingliston, Edinburgh, 23rd – 26th June 2022) will be to showcase the role of technology in ensuring conception rates from sexed semen remain on par with those from conventional semen.
“Because the sorting process can make sexed semen slightly less durable than conventional semen, conception rates from the former tend to lag 10-15% behind those typically achieved from conventional inseminations,” explains Paul Mitcham, Allflex’s monitoring sales manager in the UK.
“For this reason, as well as safeguarding its viability by ensuring sexed semen is stored and handled with care and precision, it is also vital that sexed semen is used at the optimum timing. For conventional semen the general rule of thumb is for artificial insemination to take place at around 8 to 14 hours after peak heat, but for sexed semen this should be delayed to between 14 and 20 hours.
“Relying on visual heat detection makes it difficult to determine exactly when each heat starts,” Paul continues, “which is why more and more herd managers are turning to technology to accurately detect the onset of oestrus.”
The advanced electronics housed within the latest generation of Allflex’s SenseHub collars and monitoring ear tags have been proven to accurately and reliably detect more than 95% of heats, including the majority of silent heats in dairy and beef herds. “This information is subsequently relayed to the herd manager or AI technician as easy to interpret graphs and text alerts to ensure each animal, irrespective of whether she is ear-marked to receive sexed or conventional semen, is inseminated at the optimum time. As such, each animal will have a higher chance of conceiving,” Paul Mitcham adds.
“To help dairy and beef farmers understand more about how technology can improve their herds’ fertility scores from sexed semen, Allflex’s team of herd monitoring experts will be at the Royal Highland Show to showcase the SenseHub system and to offer practical heat detection and insemination timing advice.”
The Allflex stand will also showcase the company’s portfolio of livestock tagging, tissue sampling, electronic identification (EID), weighing and handling equipment including the Alligator Pro mobile sheep handling system.
