Effects of varying protein- and amino acid contents in different pig diets
Abstract
The negative effects of a protein oversupply on the environment are well known. Nevertheless, in the past farmers have been very hesitant to implement optimized feeding strategies (i.e. phase feeding diets with reduced protein content but optimum levels of essential amino acids) for growing pigs. In the future, farmers who are growing pigs will have to prove that they are using these optimized feeding strategies in order to be eligible for subsidies. Because there is quite an uncertainty about the practical implications among farmers and extension personnel, an experiment was designed in which some of these questions were adressed under close-to-field conditions. Each one out of four different diets was fed to 20 pigs. There were 10 replicates per group, one pen with two pigs represented one replicate. The control group was fed one diet containing 17.4 % crude protein and 1.04 % lysine throughout the whole growing-fattening period. In the other three groups, different phase feeding concepts were used which resulted in different dietary protein and amino acid contents. The effects on growth, feed consumption, carcass characteristics and profitability were investigated. Besides scientific purposes, the results of this experiment will also serve as a case study for the extension service.
