The effect of the use of the emulgator Lysoforte was investigated in the 33 days” experiment on piglets. Piglets weaned at the age of 28 days were divided into two groups - experiment (E) and control (C) - 10 piglets in each. In E group Lysoforte was fed as an additive (1 kg/ton) to the commercial mixture ČOS without growth promoters. The live weight and feed consumption were recorded individually. At the end of the first week of the experiment the piglets” faeces were collected during two days to determine the digestibility of dry matter, nitrogenous substances, fibre, fat,organic matter and ash by means of a calculation of the proportion of ash insoluble in HCl. There was no effect of Lysoforte on the daily gain of piglets (C = 339 g, E = 342 g), but the feed intake per kg live weight gain was found lower (C = 1.899, E = 1.770 kg). The digestibility of all proximate feed components was found higher in E piglets - the inter-group difference for dry and organic matter reached approx. 5%, those for fibre, nitrogenous substances and ash from 9.5 to 13.4 %, and 49% for fat. The economic evaluation proved the return of increased expenses per 1 kg of the feeding mixture by adding Lysoforte from 14.40 to 14.60 CZK/kg. The cost of feed per 1 kg live weight gain was reduced by 5.5% (C = 27.346, E = 25.842 CZK).

W 33-dniowym doświadczeniu stosowano w żywieniu prosiąt odsadzonych w wieku 28 dni pasze COS (bez stymulatorów wzrostu) oraz bez dodatku (grupa kontrolna - C) bądź z dodatkiem (grupa doświadczalna - E) emulgatora Lysoforte (1 kg/tonę). W końcu pierwszego tygodnia doświadczenia określono strawność suchej masy, związków azotowych, włókna, tłuszczu i popiołu zawartych w paszy C i E. Nie stwierdzono wpływu dodatku Lysofortu do paszy na przyrosty warchlaków (grupa C - 339, grupa E - 342 g dziennie). W grupie E wystąpiła jednak poprawa wykorzystania paszy (grupa C « 1,90, grupa E - 1,77 kg/kg przyrostu. W gnipie E stwierdzono poprawę strawności wszystkich badanych składników pokarmowych. Koszt I kg przyrostu okazał się w grupie żywionej paszą z Lysofortem (E) niższy o 5,5% w stosunku do grupy kontrolnej (C).
