title: [The effect of addition of formic acid to the rations on the energy metabolism of sheep and young bulls].
abstract: Total metabolism trials were carried out with 8 fattening bulls and 4 male sheep receiving rations supplemented with formic acid. Comparative trials were performed with lucerne conservates. The following results were obtained: Formic acid supplements of up to 0.7 gm/kg liveweight per animal/day did not influence the ruminal fermentation and the digestibility of the food beyond ordinary dissimilation processes nor did they influence the energy turnover in the animals. Already in the rumen, the added HCOOH was largely broken down into CO2 and CH4. Higher levels of N retention were observed if the animals were fed fresh lucerne silage supplemented with formic acid as compared with dried green feed and the other types of silage.
