Abstract

The objective of the presented study was to examine the influence of Fusarium mycotoxins (zearalenone – ZEN and deoxynivalenol – DON), administered separately and in combination, on the activity of cecal enzymes (β-glucosidase and β-glucuronidase) in gilts which were fed fodder contaminated with these mycotoxins. The activity of β-glucosidase and β-glucuronidase varied in the range of 0.170-1.236 μmol · h−1 · mg−1 and 8.701-96.704 μmol · h−1 · mg−1, respectively. In the first two weeks, the toxins had no significant effect on the activity of β-glucosidase and β-glucuronidase in the ascending and descending colon. After week 3 and later on, ZEN and DON administered as a mixture led to the highest increase in the activity of both enzymes. Administered separately, DON affected the activity of enzymes more than ZEN. From the third week of the experiment, an increase in the activity of CW β-glucosidase and β-glucuronidase was observed.

Abstract

Introduction: The aim of the study was to determine the effects of supplementation of sows’ and growing pigs’ diets with three newly developed synbiotic and two extant commercial probiotic products on selected immune parameters under field conditions.

Material and Methods: The study was performed on 30 sows and 48 piglets of the Danbred breed. Immune parameters such as concentration and proportion of white blood cells and their subpopulations, immunoglobulins amount in serum, and serum concentration of cytokines and acute phase proteins were recorded with the use of a haematology analyser and ELISA kits.

Results: No significant differences between treatment groups and controls were found with regard to the immune parameters evaluated except for serum immunoglobulin concentration, which was significantly increased by synbiotic products B and C and probiotic product D.

Conclusion: The results of the study indicate that the synbiotic products B and C and probiotic product D are worthy of further investigation as promising candidates to improve the immune status of healthy sows and their offspring.
