FILLING the pasture-based feed gap during the winter months – one of the big profitability challenges for beef in the south – has been the focus for 2017 Nuffield scholar Stuart Tait.
With support from Meat and Livestock Australia, Mr Tait conducted global research into cost-effective ways to manage and fill the seasonal feed gap in pasture-based beef systems.
Mr Tait manages his family’s mixed enterprise across three properties on the NSW Central Tablelands, and his desire to develop a more profitable farming system and boost the business’ productivity motivated his Nuffield research.
“I felt that we weren’t fully capitalising on the climate and rainfall in our region. Wanting to make the most of the land we have, I used my Nuffield scholarship to travel throughout New Zealand, Europe, the United Kingdom, North and South America to piece together the jigsaw puzzle of more profitable grazing,” Mr Tait said.
“Beating seasonality and developing a year-round solution to fill the seasonal feed gap was a key focus of my research. I looked at innovative ways to overcome difficult autumn conditions such as stockpiling pasture, self-feeding silage pits and bale grazing.”
Mr Tait’s report, released today, makes a number of recommendations around increased data analysis, flexible enterprise mixes, and also proposes examples of annual forage sequences that allow for pasture-based production throughout the year.
One such example involves the use of dual-purpose winter wheat to recommence the crop cycle after perennial pasture.
“The forage sequences leverage productive species like cocksfoot, lucerne and chicory through spring and summer, with dual purpose wheat filling the feed curve through winter,” he said.
“This approach also encompasses innovative feeding techniques from around the world, including the use of self-feeding silage pits during the challenging autumn months.
“I started this journey to investigate dual-purpose cropping systems, but it quickly became clear that the best results are achieved when we look at the overall beef forage system, including everything from paddock subdivision to technology and data analysis.”
Another key finding of the report involves the method of pasture stockpiling, which is becoming increasingly popular in North America in the place of expensive hay making.
In addition, visiting a number of ranchers and consultants on the prairies of western Canada, Mr Tait observed the method of swath grazing, used to stockpile feed for the harsh Canadian winter.
“Swath grazing involves swathing pasture or annual crops, like oats, into windrows prior to winter. The swathes are left in situ, and snap freeze at the onset of winter,” he said.
“Cattle are given a set feed allocation, and are grazed behind an electric wire along the swathes under the snow.
"Back home, there is potential for this method to be applied to perennial grasses like phalaris, following spring periods of excessive growth. The stockpiles could then be used during the autumn period for non-lactating pregnant cows.”
Mr Tait’s research was borne from the simple understanding that increasingly, producers need to do more with what they have.
“No one is making any more farmland, so we must make the most of the land we have,” he said.
“If we can develop a resilient and simple year-round forage based grazing system, that encompasses a range of techniques and approaches, then we’ll be better placed to run productive, profitable beef enterprises for generations to come.”
