title: [Studies on the suitability of solid materials in porcine feces for use in the fattening of cattle. 1. Procedure and results of fattening trials].
abstract: Mixtures of pelleted fool containing 30% or 50% of solid material from pig semi-liquid manure were fed to fattening bulls in a 252-day feeding trial. The controls (comprising 9 animals each) received pelleted straw concentrates. The digestibility of the pellets used in these trials was tested on sheep. The animals accepted these pellets readily after a period of adjustment (consumption of dry matter per animal per day: 7.58 kg and 8.20 kg). The daily weight gains of the experimental animals were 1176.0 g and 1003.5 g. The energy required per kg of weight increase was found to be 3.72 kEFr and 4.02 kEFr. The solid materials obtained from pig semiliquid manure were found to have a lower feeding value than the pig faeces, the feeding value of the solid materials corresponding to that of meadow hay of medium quality. The solids may be used to advantage for fattening cattle when fed in combination with straw, cereals and sugar beet products.
