          Abstract

          Background

          The aim of this study was to determine the effects of plant essential oil supplementation on growth performance, immune function and antioxidant activities in weaned pigs.

          Methods

          In the study, 24 weaned pigs were used to explore the effects of plant essential oil (PEO) on growth performance, immune properties and antioxidant activities. Pigs were fed with a basal diet (CON) or basal diet containing different concentrations of PEO (PEO50: 50 ppm; PEO100: 100 ppm; PEO200: 200 ppm). After 3 weeks, all pigs were slaughtered and blood and tissue samples were collected for biochemical analysis.

          Results

          The results showed that PEO supplementation quadratically increased body weight gain (BWG) ( P = 0.031), linearly ( P <  0.05) and quadratically ( P <  0.05) decreased F:G. In addition, IgG increased linearly ( P <  0.05) and IgM increased linearly ( P <  0.05) and quadratically ( P < 0.05) as PEO supplementation. Similarly, MDA in serum, jejunal mucosa and pancreas were linearly decreased ( P < 0.05) and GSH in serum (linear and quadratic, P < 0.05), duodenal mucosa (linear and quadratic, P < 0.05) and in ileal mucosa (linear and quadratic, P < 0.05) were notably increased. Futhermore, antioxidant-related genes expression levels of GST in spleen (linear and quadratic, P < 0.05), GPX1 (quadratic, P < 0.05) and SOD1 (linear, P < 0.05) in spleen and GST in liver (quadratic, P < 0.05) were markedly upregulated by PEO supplementation increasing.

          Conclusions

          These results suggest that PEO improves growth performance, immune function, and antioxidant activities in weaned pigs, and it may also relieve weaning stress if used as a feed additive in the livestock industry. And that supplementation 200 ppm PEO in diet would seem to be economically feasible.

            Essential oil and aromatic plants as feed additives in non-ruminant nutrition: a review

            This paper summarizes the current knowledge regarding the possible modes of action and nutritional factors involved in the use of essential oils (EOs) for swine and poultry. EOs have recently attracted increased interest as feed additives to be fed to swine and poultry, possibly replacing the use of antibiotic growth promoters which have been prohibited in the European Union since 2006. In general, EOs enhance the production of digestive secretions and nutrient absorption, reduce pathogenic stress in the gut, exert antioxidant properties and reinforce the animal’s immune status, which help to explain the enhanced performance observed in swine and poultry. However, the mechanisms involved in causing this growth promotion are far from being elucidated, since data on the complex gut ecosystem, gut function, in vivo oxidative status and immune system are still lacking. In addition, limited information is available regarding the interaction between EOs and feed ingredients or other feed additives (especially pro- or prebiotics and organic acids). This knowledge may help feed formulators to better utilize EOs when they formulate diets for poultry and swine.

              Effects of dietary essential oil components on growth performance, digestive enzymes and lipid metabolism in female broiler chickens.

              1. The present experiment was conducted to describe the effects of thymol, cinnamaldehyde and a commercial preparation of essential oil components (CRINA Poultry), in female broilers. Feed and water were provided for ad libitum consumption. 2. Feed intake, weight gain and feed:gain ratio were not different among the treatments. Water intake was significantly lowered by cinnamaldehyde. Relative liver weight (g/100 g of body weight) was highest in birds given thymol, but this was seen only at the age of 21 d and not at 40 d. Patterns of digestive enzymes in pancreatic tissue were similar for the 4 treatments. 3. Amylase activity in intestinal digesta was highest in chickens given CRINA Poultry for 21 d, but the effect had disappeared after 40 d. Ileal digestibility coefficients for starch and protein were high and identical for all treatments. 4. Fatty acid composition of diet was reflected in that of adipose tissue. Plasma lipid concentrations were not changed by any dietary treatment. 5. Thus, the present results show no effect of essential oil constituents on growth performance in female broiler chickens, but it cannot be excluded that positive effects would have been observed under less hygienic environmental conditions or when using a less digestible diet.
