Top tips from past MSA Award winners

23 February 2022

Implementing a production system that revolves around the winter-dominant rainfall of Flinders Island in Bass Strait is among the keys to turning off cattle at their best for Martin and Rosemary Walker.

Martin and Rosemary, and their children, Kate, Grace, Tom and Lucy, ‘Marapana’, have been MSA-registered producers since 2006 when they diversified their Merino operation into beef production, and today run 100% grassfed Hereford and Angus herds comprising a total of 300 breeders.

In 2019, the Walkers won the MSA Excellence in Eating Quality Progress Award for Tasmania. Here, they share how they ‘made the grade’ to take away the top prize for their state.

On-farm strategies for success

The Walkers utilise a range of tools to ensure their cattle are suitable for markets including MSA.

Those practices include rotational grazing to carefully manage pastures, low-stress stock handling techniques, and using estimated breeding values (EBVs) to select bulls with desirable traits.

“The average annual rainfall here is 720mm. Due to the winter-dominant rainfall, we calve from 1 August onwards for eight weeks, and wean from 1 March onwards,” Martin said.

“We aim to turn-off the cattle at 16 months of age, in theory in December.

“All of the cattle go to Tasmania, to the north-west coast. We target the feedlot or backgrounding market usually, and in a good season, we grow more out for direct consignment as two-year-olds for processing at Greenham, Smithton.

“We try to have the numbers off by the end of spring and brace ourselves for summer when rainfall is unreliable and there is a definite feed gap.”

  1. Rotational grazing

The Walkers utilise rotational grazing practices with the cattle run on perennial pastures including ryegrass and clover, as well as phalaris, cocksfoot and fescue.

With one property on mostly sandy loam and the other mostly clay, Martin has been strategically using gibberellic acid to help bulk up their body of feed for the cold and wet winter months, leading in to calving.

Gibberellic acid is a naturally occurring plant hormone that stimulates growth through cell expansion.

“We apply it to the grass in May and June, lock up those paddocks for 30 days and the plant doubles in size for mid-winter when you need the feed,” Martin said.

  1. Using EBVs

Martin is an advocate for the MSA program because of its target specifications and the carcase feedback it provides.

In response to MSA carcase feedback, the Walkers now look at EBVs for fat cover when buying bulls from recognised studs in Tasmania.

“We select bulls based on EBVs prior to a sale, and then visual structural characteristics,” Martin said.

“The EBVs we look at are birth weight, positive rib and P8 fat cover, and 400-day and 600-day weight gains.”

  1. Low-stress stock handling

Low-stress stock handling is another important element in their production system.

“The cattle travel 45 minutes by truck to the local port, then have a nine-hour sea voyage to Tasmania, and then three hours on a truck to Greenham’s at Smithton, so it’s important that they’re quiet,” Martin said.

“With rotational grazing, I’m amongst them regularly so they’re used to having me around, and I’ve also done a stock handling course, which has been helpful in learning how to move amongst them.”

Final tip:

All of these elements go into producing cattle that achieve MSA compliance, and Martin said his best tip for other producers is simple: “Have them in as good condition as you can.”
