siMMinTM:On Line Software Tool to Simulate Zinc Balance in Feeding Programs of Growing Pigs
Copper and zinc are essential nutrients that are usually supplied above nutritional requirements in pig diets.As a result,high Zn and Cu concentrations are found in animal wastes.which poses a risk of soil accumulation when pig manure is spread on arable land.Moreover,technological treatments of pig slurry concentrate zinc in the solid fraction and this by-product may exceed maximal authorised Zn content when used as organic fertiliser.The mass balance approach has been recently updated to measure the excretion of heavy metals (Cu,Zn)from pig production.siMMinM has been developed with the support of INRA with the following objectives:-the software should be intuitive and easily usable in any pig farm whatever the conditions ;-it focuses on the pig growing life,from the weaning until slaughter;-calculation can be adapted to each user,taking into account farm variables of pig growth performance and feeding program ;-the software enables to simulate changes in each variable compared to the existing situation,in order to measure the rate of improvement in the total reduction of zinc in the life of the growing pig and the change in Zn concentration of animal waste;-the calculator tool benchmarks any situation to existing EU regulation.The software is on line since January 2013 at www.animine.eu/simmin/and can be utilised by all stakeholders involved in pig production.
