“…The requirement of valine for young rainbow trout was lower than that reported for juvenile rainbow trout [25,26]. In vertebrates, growth largely relies on intestinal health [50], which is correlated with the intestinal mucosal immune [51,52]. As mentioned above, valine-insufficient diet causes growth reduction in young grass carp, which led us to hypothesize that valine deficiency have negative effect on intestinal mucosal immune for fish.…”

“…Plants contain many active substances such as phenolic compounds (mainly tannins and flavonoids), essential oils, and others (Reuter et al, 2007;Schnitzler et al, 2008). Herbs can be used as dried parts of plants (Kong et al, 2007a) or as extracts prepared mainly using water or ethanol as solvents (Kong et al, 2007b). Such extracts are more practical than dried plants because of their higher content of active substances and easier application.…”

ABSTRACT:The effect of a mixture of herbal extracts on piglet performance was estimated on 178 piglets allocated to 3 groups comprising 6 litters each. Group I (control) was fed with the standard barley-wheatsoybean mixture. Group II received the same mixture supplemented with a blend of formic and propionic acids. Group III received the basal diet supplemented with a mixture of water extracts from sage, lemon balm, nettle and coneflower (20, 30, 30, and 20%, respectively) at 500 mg/kg feed. The experiment lasted for 84 days but on day 56 six piglets from each group were slaughtered and their gastrointestinal tract was removed. Apparent digestibility was estimated using the Cr 2 O 3 indicator method. Acidity of digesta was measured in the stomach, ileum, and caecum, and volatile fatty acid content was evaluated in the ileum and caecum. Amounts of bacteria and morphological structure were evaluated in the ileal digesta and epithelium, respectively. In the experimental groups less dead and culled piglets were observed than in the control group. Piglets in the herb-supplemented group grew faster than control animals and showed significantly higher final average body weights. There was no significant difference in feed utilization. Acetic acid content was higher in both groups receiving supplements. The amount of propionic acid in the caecum of animals from the herb-supplemented group was lower than in animals from groups I and II. There were no significant differences in bacteria population in ileum chyme. The herbal extract improved the structure of the ileal epithelium by significantly increasing villus height. Better digestibility of nutrients could be due to higher villi in this group. Keywords: piglet nutrition; ileum; intestine morphology; plant extracts Herbs and their extracts have been used in human and veterinary medicine for a long time (Viegi et al., 2003). Plants contain many active substances such as phenolic compounds (mainly tannins and flavonoids), essential oils, and others (Reuter et al., 2007;Schnitzler et al., 2008). Herbs can be used as dried parts of plants (Kong et al., 2007a) or as extracts prepared mainly using water or ethanol as solvents (Kong et al., 2007b). Such extracts are more practical than dried plants because of their higher content of active substances and easier application. Herbs probably may replace antibiotics and synthetic growth promoters banned by the European Union (Namkung, 2004).The positive effect of herbs in pig feeding was found by Mellor (2000). Paschma (2004) examined the influence of herbal supplements on sows' performance. The beneficial effect of herbs added to feed mixture for fatteners on their weight gains, carcass meat content, and meat quality was noted by Szewczyk et al. (2006) and Hanczakowska et al. (2007). Sage (Salvia officinalis) contains essential oils which have strong antimicrobial and antioxidant activities (Bozin et al., 2007). Another plant with similar properties is lemon balm (Melissa officinalis), the antimicrobial activity of which was fou...
