Minimum inclusion levels of copper and zinc proteinate maintain performance and reduce faecal excretion in growing and finishing pigs
Hernández, A., Mullan, B.P., D'Souza, D.N. and Pluske, J. (2007) Minimum inclusion levels of copper and zinc proteinate maintain performance and reduce faecal excretion in growing and finishing pigs. In: Manipulating Pig Production XI. Proceedings of the 11th Australasian Pig Science Association (APSA) Biennial Conference, 25 - 28 October, Brisbane, Australia p. 44.
Hernandez et al (200S) found that total dietary levels of 25 ppm copper (Cu) and 40 ppm zinc (Zn), in the sulphate or proteinate form (Bioplex®), reduced the concentration of Cu and Zn in faeces by 80 and 60% respectively and maintained the growth of growing pigs, compared to a diet containing 160 ppm of both Cu and Zn. These results indicated reduced levels of supplemental Cu and Zn might be possible. In the present study we therefore measured the impact of increasing inclusion levels (IL) of Cu together with low (treatments 1-4) or high (treatments S-8) IL of Zn in the Bioplex® form on performance and faecal levels.
