“I had been thinking about our cow feeding problem for a long time,” says John Cockerell of Warrain Jersey Stud, at Waaia in northern Victoria. “We had been feeding silage twice a day, and a lot was being left in the paddock as waste. We also needed a system that filled a void in their intake at milking time.”
“Over time I looked at other systems, they were either too big, too much work, or too expensive. Then, at a field day, I found a system which was exactly what we wanted.”

John and Margaret Cockerell’s stud has been established for over 30 years, beginning at Apollo Bay, then moving to a 120 acre (47 ha) soldier settlement block at Waaia in 1980. In 1992 they purchased next door and then a block further over in 1998. They now have a total of around 340 acres (136 ha).
John says that they have an effective cropping, pasture and grazing area of around 118 hectares. Cow numbers have peaked at 330, and they are currently milking 325. They also carry about a hundred 15 to 24 months old heifers, plus another 74 yearlings.
Focus on Production
The breeding program is 100% AI, and John and Margaret have been using US bloodlines for over 18 years.
“We are aiming at what we call a ‘functional dairy animal’, with a focus on improving udder wearability. We are totally production- orientated, driven by the ability to service debt. That has been critical just as much in the past as it is now. We’re now using mainly US bulls and a small amount of Danish and Canadian blood.
“Our cows are much bigger than the traditional Australian Jersey milker of a few years ago, but with our systems and experience over the years, we can manage them bigger.”
The Cockerells have a 22 swing-over shed, using a DeLaval plant with automatic removers, with Larsen stall gates. Margaret says milking takes about two hours and 2_ hours in spring with fresh cows. The cows get grain and a protein and mineral supplement in the bail.
In 1999 they put in a Waste-Not Fair-Go dairy feed pad with room for a ‘batch’ of 66 cows each side - the equivalent of three sides of their milking shed.
The cows go straight from the milking shed to the feed pad. It takes about 25 minutes to milk each batch, so the cows spend a minimum of 25 minutes - and up to 40 minutes - feeding at the pad. The aim is for them to eat approximately 2 kg dry matter of feed.
Huge Production Increases
John says that the resultant lift in milk production has been outstanding: “When we started using the Waste-Not feed pad, we jumped 850 litres per cow in the first year. The second year we increased a further 300 litres per cow. This was all without feeding any more grain. We just changed the feeding pattern.” The cows at Warrain Jerseys are now averaging 6500 litres per year.
Protein has jumped from 225 to 265 kg, and butterfat from 270 to 315 kg under the Waste- Not Fair Go system. John says these are the numbers which really count and shows the value of the feeding system.
This feed pad design, which works well for any size of dairy operation, allows operators to maintain pasture as the focus on the farm, and ensures that animals are getting a fair ration and a controlled amount of fibre.
“We like to think that they’re eating more because they have more time to eat” says John.
The Cockerills put in an 18” raised dirt pad topped with 12” gravel to start with, and then concreted that over after a year. This size of feed pad is relatively smaller than most people would expect for these herd numbers, and so concreting the area becomes feasible.
Margaret says that the area where the cows are standing whilst feeding used to get chopped up a bit as the cows dug in their rear feet to get purchase. But the area is now very easy to clean. Manure is all contained on the concrete, and John or their son, Edan, just picks up the manure with a front end loader, and spreads it back onto the paddocks.
They are looking to improve this access area for even better cow flow, and also to improve the effluent disposal side of the system.
Quality Feed is the Key
They mainly feed round bales of silage, or alternatively good quality clover hay and lucerne, depending on the season.
John or Edan replaces some of the feed each day as it is eaten, but it is all generally eaten out over a maximum of three days. According to Terry Allan of Waste-Not Stockfeeders, this is the ideal rate of consumption of the feed.
“We originally planned to keep the feeder full all the time, but secondary fermentation of the uneaten silage on the bottom of the pad became a problem. Now we just refill it when it’s needed.
“We went from conventional round baled silage to chopped and inoculated silage, which means that you can get more feed into a bale. A 4’ x 4’ chopped bale gives more feed and dry matter at the same cost, so you might as well get as much as you can.
“It is really important to control what you put in. The better the quality, the more they’ll eat it up. We can quickly tell if there’s lower quality because intake drops. If it’s baled right, with the right pH, it’s OK for three days without getting hot. The biggest thing is that we believe we can stabilise rumen pH, because of the fibre that they get from the feed pad. |
