Abstract: A scientific experiment was conducted with five lambs, a cross between breeds Meat Stara Zagora and Pleven Black-headed. The influence of the addition of feed material from grain distillery industry on cellulolytic activity,
total and generic composition of rumen infusoria in lambs has been investigated. Zarnela - spirit producing dried residue from wheat (DDGS - Dried Distillers Grains with Solubles) is a feed additive, a byproduct from the production of ethanol from feed material - wheat. Production plant is alcohol in center of Gorna Oriahovica, Bulgaria .
The assay was performed in two periods - the control and experimental. During the control period the animals received a ration consisting of 1.000 kg meadow hay and 1.000 kg barley. During the experimental period the ration consisted of 0.800 kg barley mash , 0.200 kg grain and 1.000 kg meadow hay. The following indicators: cellulolytic activity of rumen microflora, total and generic composition of rumen infusoria were investigated.
The addition of the feed material grain Zarnela affects rumen fermentation in lambs as:
1. Increasing no significantly cellulolytic activity of rumen microflora.
2. Total number of rumen infusoria during the test period after the addition of Zarnela was increased (P<0.05, P<0.001) at all hours of the study.
3. The addition of Zarnela does not lead to significant changes in the generic composition of rumen infusoria, both before and after feeding.
