[Nutrient supply of health and sick fluid fed calves].
In the department for calves being fed with fluid feed of a specialised enterprise for calf rearing the daily intake of fluid feed (skim milk improved with milk substitute), concentrated feed and hay of a total of 341 female animals and the daily intake of energy and protein was calculated thereof. The average consumption of nutrients of the 206 healthy calves was compared with some international and national norms for the demand of nutrients. The comparison with some international values of demand and the results of the partial correlation analysis between energy and protein intake and live weight increase showed that the applied nutrition regime (particularly the kind of fluid feed) has resulted in an excessive supply of the calves with proteins and an insufficient supply with energy. This could not be realised from the GDR nutrients norm for the raising of calves published in 1976. Based on theoretical considerations and some recent findings of the science of nutrition we derived values of the protein and energy demand of our own. Subsequently an attempt is made to assess the supply with nutrients for sick calves.
