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

摘要

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.
