“…Yan et al (2012) observed that dietary supplementation of Taraxacum officinale, a medical herb, significantly increased (P<0.05) the ADG and G:F in weaning pigs. In the study by Li et al (2012), the addition of EO containing thymol and cinnamaldehyde at 100 and 150 g/tonne improved (P<0.05) the daily weight gain and feed conversion ratio (FCR) of weaner pigs. Likewise, Ouwehand et al (2010) reproted that the mixture of thymol and cinnamaldehyde would have the best potential to control the proliferation of pathogenic bacteria and contribute to better gut health.…”

Phytogenic feed additives have become attractive alternatives for use in animal diets. The objective of the present study was to evaluate the effect of a phytogenic-based feed additive on growth performance, nutrient digestibility, blood profiles, fecal noxious gas emission, and intestinal morphology of weaning pigs after dietary challenge with E. coli K88. A total of 120 crossbred pigs [(Yorkshire × Landrace) × Duroc)] with an initial body weight (BW) of 6.09 ± 0.96 kg (21 d of age) were assigned randomly to 1 of the 4 dietary treatments. Each pen housed 5 pigs, and there were 6 pens/treatment. Treatments included: T1, negative control (without antibiotics); T2, T1 + antibiotic; T3, T1 + 0.05% phytogenics; and T4, T1 + 0.2% commercial mix of organic acids. Overall, the average daily gain (ADG) with the T3 treatment was higher (P<0.05). At wk 1, the apparent total tract digestibility (ATTD) of dry matter (DM) was increased (P<0.05) with T4 treatment. The ATTD of ash with T3 and T4 treatments was greater (P<0.05). At wk 3, pigs fed with the T4 diet had a significantly higher (P<0.05) ATTD of DM. The ATTD of ash and calcium (Ca) was significantly increased (P<0.05) with the T4 treatment. Pigs fed with the T3 diet had a higher (P<0.05) ATTD of phosphorus (P). At wk 6, the ATTD of ash was significantly increased (P<0.05) with the T1 and T3 treatments. The data indicate that phytogenics positively affect growth performance of weaning pigs, indicating that their use as an alternative in the diets of weaning pigs can significantly improve ADG, under challenge with E.coli K88.

“…In the treatment, OE increased the growth performance and nutrient digestibility in finishing pigs. Moreover, other studies have suggested that essential oils improved growth performance, measured in terms of BW, ADG, ADFI, and G : F, because they stimulated intestinal enzymes, leading to increased nutrient digestibility, balance of microbiota, and feed intake (Huang et al, 2010;Li et al, 2012b;Lan et al, 2016). Additionally, a previous study revealed that a microencapsulated feed containing organic acids and essential oil added to finishing pig diet could increase growth performance, nutrient digestibility of DM, and energy (Cho et al, 2014).…”

Experiment 1 was a feeding trial in which 75 (LandraceⅹYorkshire)ⅹDuroc pigs with average initial bodyweight (BW) of 26 ± 1 kg were used. It was assigned to three pigs/pen and five pens/treatment. Experiment 2 was a metabolic trial in which 25 (LandraceⅹYorkshire)ⅹDuroc pigs with average initial bodyweight (BW) of 36 ± 1 kg were used. The basal diet consisted of maize (57.71 %), soybean meal (32.45 %), and wheat bran (5 %). Treatments consisted of i) CON (control diet); ii) OE (organic acid + essential oils) (Aviplus-S ® ), that is, CON + 0.05 % OE; iii) OC (organic charcoal) (Olga Black ® ), that is, CON + 0.1 % OC; iv) AE (anise extracts) (RESQ ® ), that is, CON + 0.015 % AE; and v) PB (probiotics) (Bonvital ® ), that is, CON + 0.1 % PB. Average daily gain (ADG) and gain/feed ratio (G : F) were significantly higher in the OE and AE groups than in the others. Average daily feed intake (ADFI) for OE, OC, and AE treatments was significantly higher than that for CON and PB treatments. Dry matter (DM) digestibility was significantly higher in AE than CON. Crude protein (CP) was significantly higher in OE, AE, and PB than CON. CON and other treatments did not cause significant differences in blood l-density lipoprotein (LDL), and glucose. NH 3 emissions were significantly lower in all treated groups than in CON. Among the treatments, NH 3 emissions were lowest in OE and AE. H 2 S emissions were significantly lower in OE, AE, and PB than in CON. Among the treatments, OE and AE were most effective at reducing H 2 S emissions. The emissions of volatile fatty acids (VFAs) showed no significant difference between treatments and CON. In conclusion, this experiment was shown to be more effective on growth performance, malodour emission, blood profiles, and nutrient digestibility in OE and AE than other additives.

“…It was found that encapsulated essential oils containing thymol and cinnamaldehyde reduced the incidence of diarrhea by 50% and enhanced the immune status of newly weaned pigs. The addition of essential oils also improved the performance of piglets, resulting in greater growth rate and improved feed conversion rate (Li et al, 2012).…”

“…They are plant secondary metabolites which contain complex mixture of volatile compounds with variable chemical compositions and concentrations (Li et al, 2012). It has been recognized that some essential oils can be used as antimicrobial agents because of their ability to control foodborne pathogens (Burt et al, 2004).…”

Each category of pigs is susceptible to diseases caused by pathogenic bacteria, which negatively reflects on animal health, farm production results or meat quality. Animal feed is one of the potential reservoirs of pathogenic bacteria and infection source of domestic animals. Salmonella spp. is major microbiological hazard in animal feed. Thus, there is importance for implementation of strategies for preventing feed contamination with Salmonella, by minimizing dust, maximizing hygiene of space and processing equipment in feed mills and implementing control measures in each stage of feed production. Existing Salmonella feed contamination can be eliminated by conditioning and later different heat treatments (pelleting, extrusion, expansion) in production process while changing physical structure of the feed (coarsely or finely ground mash or pellets) can influence on conditions for Salmonella development in gastrointestinal tract of pigs. Contamination of feed by pathogenic bacteria and conditions for their development can be also controlled by addition of acidifiers, prebiotics, probiotics and, more recently, essential oils of plant origin, into feed. Various strategies for prevention of feed bacterial contamination, processes for feed decontamination, as well as possibilities for controlling pathogenic bacteria, especially Salmonella, in pig feed were presented and discussed in this article.
