Abstract:
The content of crude nutrients, minerals and amino acids from kitchen waste were determined. The study was carried out on six selected pig farms and took four weeks in June and September. The content of dry substance, crude nutrients and minerals differed highly between the waste of different kitchens. In opposite to this findings the daily and weekly analysed crude nutrients and minerals were not remarkably different within one farm. The average fat content of the garbage was between 12.2 % of dry matter in one farm using the kitchen waste of two homes for old people and 32.2 % in another one using the kitchen waste of 10 restaurants. The protein:energy ratio was 10.9:1 or 11.4:1, respectively. The average lysine content was higher than 5 g/16 g N and lysine:methionine plus cystine: threonine ratio was about 1:0.6:0.6. Performance results measured on the 6 farms were used to test the applicability under practical conditions. Kitchen waste with an adequate supplementation was found to have good performance results. Due to the small differences in nutrient content of the same kitchen waste, analyses of garbage seem to be sufficient every three months. An economical evaluation of different ways of use was found on the basis of estimations and informations given by the farmers. There should be paid a producer fee of 0.10 - 0.17 Euro per kg garbage to enable an efficient utilization.
