Whole-crop snips beef costs
BEEF animals have finished at under 50p/kg of liveweight gain when fed fermented whole-crop wheat on one Yorkshire farm.
So the audience at the Maize Growers Association whole-crop conference last week was told by farm manager Ian Burton, Marton Hall Farm, Skipton.
The feed costs compared well with claims made for cereal systems at 75-80p/kg gain and grass systems at 51p/kg gain, he added. And even in this difficult year the beef enterprise made a margin.
The farms costs for rearing bulls from its 150-cow dairy herd were based on feeding fermented whole-crop ad lib from 12 weeks until finishing. Bulls ate a total of 5.3t a head of whole-crop supplemented with 1kg a head a day of a 20% protein blend.
"Blends of under 20% protein resulted in lower production, but when over 20% protein was fed there was little benefit," said Mr Burton.
The bulls, finished at 13-15 months old, were mainly Holstein Friesian, with some Simmental and Charolais crosses and averaged 1.12kg a day liveweight gain. "Feeding whole-crop produces a lean animal that the buyer wants," he said. Bulls weighed 500-550kg and killed out well at a fat class of 2 to 4. Other benefits of feeding whole-crop were good animal health with no metabolic problems and low bedding costs compared with wetter diets.
Mr Burton grows wheat for whole-crop because the cold, wet climate is unsuitable for maize for the dairy herd. He also claimed it was unlikely the wheat grain would ripen enough to combine it.

Whole-crop wheat helps provide a low-cost diet for Ian Burtons bull beef.
