Summary
A feedlot productivity study of 450 head, testing groups of cattle with two doses of powdered Calcium Peroxide and a control was commenced at Tullimba feedlot, but was terminated after five days due to persistent cattle refusal of the diets containing Calcium Peroxide.
Objectives
1. Delivery of a 450 head (45 x 10 head pens), 100 day feedlot productivity study to evaluate the effect of two doses of powdered Calcium Peroxide and a control group on feedlot performance (DMI, F:G, ADG) and carcase characteristics (HSCW, MSA grading data).
Key findings
A feedlot productivity study of 450 head, testing groups of cattle with two doses of powdered Calcium Peroxide and a control was commenced at Tullimba feedlot, but was terminated after five days. The productivity study occurred prior to the respiratory calorimetry study. A decision to terminate the experiment was made as the intake of the Calcium Peroxide treatment groups was unacceptably low (40 to 60% compared to control) impacting the ability to be slaughtered at the same time as the Control group and cattle welfare. The respiration chamber experiment was not commenced.
Benefits to industry
This study, whilst unsuccessful, provides valuable information to industry and highlights the need to consider the physical and chemical properties of new potential products and the delivery mechanisms of those chemistries.
MLA action
MLA will continue to invest and look for new ways to reduce enteric methane emissions of cattle whilst increasing productivity of animals.
Future research
Further research on incorporating Calcium Peroxide into a coated pellet is recommended to overcome handling risks as well as reactivity in the mouth before reaching the rumen.
