Special Issue Information

Dear Colleagues,

The enhanced awareness of global consumers regarding animal welfare has led to an increase in the use of phytogenic feed additives to mitigate the negative effects of stress on farm animals in recent years. Therefore, the development of alternative phytogenic feed additives and novel plant extracts is urgent, as this would improve the productivity, health, and welfare of animals. Rapid developments regarding the potential application of phytogenic feed additives have occurred, mainly due to the 2006 EU ban on the use of antimicrobial substances as growth stimulators; however, they are also used as sensory, technological additives or substances, thus positively affecting the quality of animal products.

This Special Issue aims to publish original research papers and reviews on the use of phytogenic feed additives or plant extracts in stress mitigation in farm animals. The key areas of interest include the use of phytogenic feed additives or plant extracts to enhance animal productivity and the innate immune response, and reduce the inflammation response.

The scope of this Special Issue therefore includes

  1. the use of phytogenic feed additives (PFAs) to mitigate the negative effects of stress;
  2. the roles of bioactive compounds of different PFAs, such as polyphenols and flavonoids, antioxidants, growth-promoting and immune-modulating agents, in stress management in farm animals.

This study investigated the effects of a phytogenic feed additive (PFA) containing a blend of herbs, plant extracts and essential oils from the Lamiaceae, Schisandraceae, Zingiberaceae and Fabaceae families on the fecal score, intestinal histomorphology and fecal excretion of F4-fimbriated enterotoxigenic Escherichia coli (F4-ETEC) in post-weaning piglets. Thirty 31-day-old weaned piglets were randomly allocated to three treatment groups. The positive control (PC) group received colistin via drinking water from d 8 to 14 post-weaning and the same basal diet as the negative control (NC) group; the treatment group received the basal diet with PFA supplementation (1 g/kg of feed). The experiment lasted 21 days. At day 9 post-weaning, all piglets were orally administered 3.0 × 1010 CFU/piglet of the F4-ETEC strain. The PC piglets had higher fecal consistency than the NC and PFA piglets. PFA supplementation resulted in a lower percentage of piglets excreting F4-ETEC in the feces on days 4–7 post-challenge than in the NC group (p < 0.05) but a higher percentage versus the PC group on day 3–7 post-challenge (p < 0.05). The number of goblet cells (GCs) in the jejunum of the PFA piglets was higher than the NC and PC piglets (p < 0.01). The GC density in the jejunum of the PFA piglets was larger than in the PC piglets (p < 0.05) and similar to the NC piglets (p > 0.10). Mucus thickness in the jejunum of the PFA piglets was similar to the NC piglets and PC piglets (p > 0.10). In conclusion, PFA supplementation to the F4-ETEC-challenged piglets reduced the prevalence of fecal E. coli excretion and improved jejunal histomorphology. Full article
