Farm Table says:

Little outdated, but interesting research on use of stale bread and bread rolls in a feedlot setting.

What is the problem?

Intensively feeding animals can be a costly exercise, and as a result many producers are exploring innovative ways to reduce their input costs. Commercial by-products from the human food industry (eg brewers grain, citrus pulp and apple pulp) have recently become popular in animal production. Bakery waste displays favourable characteristics for animal production, however, limited information is available on its use in feedlot rations.

This trial aimed to understand if bakery waste could be successful in a production ration for intensively fed sheep.

What did the research involve?

  • Dietary treatments consisted of three levels of bread: 0%, 25%, 50%
  • 21 merino weaners allocated to one group and fed rations for 70 days.
  • Bread used was predominately sliced bread and bread roles. The bread was dried and crushed prior to incorporation into the rations.

What were the key findings?

  • No significant difference in LWG between treaments
  • Feed intake lower in 50% bread group
  • Feed conversion and wool growth higher in 50% bread group
  • No clinical signs associated with digestive upsets evident
