STUDY OF DIGESTAROM® 1324 EFFECT ON SELECTED PARAMETERS OF MAIZE DDGS QUALITY IN PIG NUTRITION

Abstract

A digestibility experiment using six ileally cannulated growing gilts (initial body weight 39.9 kg) was carried out to study the effect of DIGESTAROM® 1324 - phytogenic feed additive supplemented to the diet, on total tract and ileal digestibility of nutrients. The main components of the diets (56.6 %) were maize-based distillers dried grains with solubles (DDGS) - produced from the fuel ethanol industry- supplemented with starch (20 %), sugar (20 %), minerals and vitamins (2.4 %). Cellite (1 %) was added to the diets as a source of acid insoluble ash. The tested preparation DIGESTAROM® 1324 was added to the experimental diet D in amount of 0.03 %. Diet C was the control diet. The supplementation of DIGESTAROM® 1324 to the diet insignificantly improved total tract and ileal digestibility of dry matter, organic matter, nitrogen, ash and phosphorus. The increase was within the span 0.6 – 2.2 %. Values of apparent and true ileal digestibility of amino acids were higher in the experimental diet D compared with the control diet C for all amino acids except for histidine. The improvement varied from 0.2 % (leucine) up to 15.2 % (proline). The tested preparation DIGESTAROM 1324® influenced positively but no significantly all parameters studied in the experiment.
