The growth potential of copper when fed at levels of 100 to 250mg/kg is widely recognised. It has been suggested that copper acts in an antibiotic-like fashion by influencing microflora in the gut1. The solubility of the dietary Cu source has also been identified as a factor related to copper simulated growth2 implying observed benefits are partially due to absorbed Cu. It is suggested that Cu binds to peptides and amino acids in the gut, and that this aids in Cu absorption3. The growth response of Cu in young pigs is affected by source.

Key Findings

In a series of seven trials
• Pigs fed 100ppm Cu from Zinpro CuPLEX® copper lysine grew faster and consumed more feed than pigs fed a higher level of Cu (200-250ppm) from ordinary copper sulphate (figures 2 &3);
• Overall pigs fed CuPLEX® were 0.58kg heavier and consumed 39g more feed per day than pigs fed ordinary copper sulphate (figures 1 & 2);
• Previous research indicates that both CuPLEX®, and Availa®Cu have similar efficacy
