[Digestibility of nutrients in a feed mixture in certain swine helminthiases].
The average digestibility coefficients of feed mixture nutrients in pigs infected medium severely to severely by the helminths Ascaris suum and Oesophagostomum dentatum were lower in comparison with the post-dehelminthization condition (dry matter by 3.1%, crude protein by 6.7%, fat by 8.9%, nitrogen-free extracts and fibre by 2.2%, organic matter by 3.1%). The content of total digestible nutrients made 679 g in infected pigs and 708 g in dehelminthized pigs. In the period following the experimental infection of pigs by the helminths Ascaris suum, characterized by the formation of antibodies and adaptation after heavy injury of the organism, the digestibility coefficients of feed mixture nutrients were in comparison with the state prior to infection influenced positively. In two metabolism trials, on the 9th to 13th day after infection the digestibility coefficients increased as follows: of dry matter by 4.8% and 3.6%, crude protein by 8.2 and 4.2%, nitrogen-free extracts and fibre by 2.0 and 3.5% and organic matter by 3.0 and 3.3%. The decrease in fat digestibility coefficients was observed in both cases, by 12.4% and 9.9%. Prior to infection the content of total digestible nutrients was 712 g and 682 g, after infection 731 g and 707 g.
