FTAI captivates cattle farmer

John Roberts, a Braidwood cattle farmer, says he will use the fixed-time artificial insemination method this season after yielding positive results previously.

John Roberts puts his in-calf heifers out on hilly country to get them fit before calving. As a result, he says, he does not pull many calves.

With his wife Fay, Roberts runs up to 600 head of black cattle at Braidwood, NSW. They moved out of Herefords in the 1980s and are now constantly on the lookout for incremental improvements that will add to the bottom line.

Two years ago, after a chance meeting with a vet who was a proponent of Fixed Time Artificial Insemination (FTAI), Roberts decided to give it a try over about 100 heifers. He liked what he saw the first year and is repeating the process this season.

“About 50 per cent of them got in calf to AI through the sync program, which is a pretty good outcome. We got a compressed calving period with them, which gives us a run of early growth young cattle.”

Roberts wants to lift the quality of the gene pool in his herd to get better muscling and quicker weight gain.

“We chose to use the high ranking ABS bull, Millah Murrah KLOONEY K42. That’s one of the advantages of an AI program – we can choose high quality bulls that get the genetic gain going.”

Local vet John Sullivan manages the synchronisation program and does the insemination work. He sees many benefits in a fixed-time process for beef producers, not least of which is the ‘whole of breeding life’ benefits from getting heifers in calf earlier.

“The earlier we can get a heifer in calf, the more chances we have of getting her in calf next time,” Dr Sullivan said.

A distinct difference between FTAI and a normal AI program is the reduced labour requirement as no heat detection is required with FTAI. With FTAI, a manageable mob of up to 100 cattle can be processed in three yardings over 10 days.

“The heifers are synced in a single session and then inseminated 10 days later. There’s usually about a six hour window in which to get the whole mob done,” Dr Sullivan said.

Most of the cost of medication for the FTAI program is offset by the reduced labour costs. By bringing calving forward and delivering a group of young cattle with uniform weaning weights, producers can expect a sales benefit that outweighs the extra effort in managing a more concentrated AI program.

The benefits of the FTAI program are about improving the genetic profile of the herd over a number of years.

“The fixed time AI program changes the structure of the herd over time,” said Dr Sullivan.

John Roberts is pleased with the program so far and plans to continue it with his heifers for for the time being.

“It will help us to upgrade the gene pool in our cattle and improve the genetic base,” Roberts said.
