Abstract
Two experiments comprising 24 calves, lasting 44–46 days, have been carried out in order to examine the influence of powders from heat-treated skim milk and whey on indigestion in young calves. The frequency of diarrhoea increased much (P < 0.01) in the first experiment when feeding the heat-treated products, but little in the other. Possible reasons for this difference are discussed. Calves fed heat-treated products in the first experiment consumed 13.8 1 of electrolyte fluid per head per day 14–22 days after commencing the test, when both diarrhoea and fluid consumption reached peak values. It is postulated that some of the calves might have succumbed without electrolyte fluid.

Sammendrag
To forsøk over 44–46 dager med i alt 24 kalver har vært utført for å undersøke virkningen av pulver fra varmebehandlet skummet- mjølk og myse på indigestion hos unge kalver. Hyppigheten av diaré 0kte mye (P < 0,01) i det første forsøket når det ble gitt varmebehand- lete produkter’ men lite i det andre. Mulige årsaker til denne forskjellen er diskutert.
Kalver gitt varmebehandiete produkter i det første forsøket drakk i gjennomsnitt 13,8 1 elektrolyttvæske pr. dag 14–22 dager etter be- gynnelsen av forsøket. Både diaré og væskekonsum var da på det høgste. Det ble antatt enkelte kalver ville ha bukket under dersom de ikke hadde fått elektrolyttvæske.
