Badania nad wplywem preparatu ziolowego podawanego maciorom na ultrastrukture komorek trzustki zewnatrzwydzielniczej u prosiat

The aim of the studies was to establish on the basis of ultrastructural examinations whether the tested herbaceous preparation added to the feed of sows may influence pancreas activity (pars vesicularis) of suckling piglets. The tested preparation contained: Folium urtice, Fructus Silybi mariani and Exocarpium fagopyri. The preparation was added to feed once daily at a dose of 20 g/animal from the 90th day of pregnancy to the 28th day of lactation. Pancreas for ultrastructural examinations were collected immediately after slaughter from randomly selected 1 and 21 day-old-piglets. It was found that the examined preparation had a positive effect on sows and also on the pancreas ultrastructure of piglets. Active substances of the examined preparation acting both directly and in interaction with endogenous factors stimulated pancreatic secretion. In older piglets the preparation also intensified exocythose.
