“…In our previous reports, the dietary supplementation of a microencapsulated organic acid blend with inorganic acids such as MCFAs or essential oil had positive effects on the growth performance and nutrient digestibility in growing (13) and finishing pigs (14,15), but not yet in layer hens. Thus, the objective of the present study was to evaluate the effects of a microencapsulated organic acid blend with MCFAs on egg production, weight, quality, fecal microflora, and nutrient digestibility in laying hens.…”

A total of 144 Hy-Line brown laying hens were used in a 10-week trial to evaluate the effects of a microencapsulated organic acid blend with medium chain fatty acids (MCFAs) on egg production, weight, quality, fecal microflora, and nutrient digestibility in the hens. The hens were divided into four groups and different dietary treatments were given to each group. The control group received no microencapsulated organic acid blend with MCFAs. The second group received 0.05%, the third group received 0.1%, and the fourth group received 0.2% of a microencapsulated organic acid blend with MCFAs. Laying hens fed on a microencapsulated organic acid blend with MCFAs showed an increase in the egg production rate (linear, P > 0.001), in the Haugh units (linear, P = 0.010), and in eggshell strength (linear, P = 0.012; quadratic, P = 0.005). Also, the same hens had higher calcium concentrations in the blood at 35 weeks (linear, P = 0.042). The dietary supplementation of a microencapsulated organic acid blend with MCFAs increased the Lactobacillus fecal content and decreased the E.coli fecal content in the hens. In conclusion, the microencapsulated organic acid blend with MCFAs had positive effects on egg production, egg strength, Haugh units, calcium concentration, and fecal Lactobacillus and E. coli contents in laying hens. Thus, we suggest that the microencapsulated organic acid blend with MCFAs could be used as an alternative to antibiotics in laying hens.

“…In our previous reports, the dietary supplementation of MOE had shown positive effects on the performances in poultry (Mohammadi Gheisar et al 2015) and finishing pigs (Cho et al 2014). The study on the effect of MOE supplementation in sows is limited.…”

“…Organic acids (OA) and essential oils (EO) supplementation has shown a functional similarity to antibiotics, thus offering an interesting alternative to growth-promoting source in livestock nutrition. Previous reports indicated that OA and EO supplements in pig diets had beneficial effects on growth performance (Cho et al 2006;Wang et al 2009;Grilli et al 2010;Gong et al 2014), nutrient digestibility (Yan et al 2010;Cho et al 2014) and both of them are appropriate antibiotic alternatives in swine diets (Rota et al 2004;Mroz 2005). Similar benefits generated by the inclusion of OA and EO to sows diets have been reported by other authors (Kis & Bilkei 2003;Allan & Bilkei 2005;Miller et al 2009;Kluge et al 2010;Ariza-Nieto et al 2011).…”

“…Previous studies indicate microencapsulation would increase the effects of OA and EO (Burnell et al 1988;Cho et al 2014;Zhang et al 2014;Mohammadi Gheisar et al 2015;Upadhaya et al 2015a,b;Mohana Devi et al 2016). The effects of micro-encapsulated organic acids and essential oils (MOE) in pigs and poultry have been variable because of different study conditions and differences in the type of MOE used as well as variation in the dose provided (Zhang et al 2005;Upadhaya et al 2014;Mohammadi Gheisar et al 2015;Lee et al 2015).…”

This study was conducted to evaluate the effect of microencapsulated organic acids and essential oils (MOE) on reproductive performance, nutrient digestibility, piglet diarrhoea score, and blood profiles in sows and suckling piglets. A total of 60 multiparous sows (Landrace Â Yorkshire) with an average initial body weight (BW) of 249.47 ± 11. 62 kg were used and randomly subjected to three treatments such that 20 replicates per treatment were maintained in this trial. Dietary treatments consisted of a basal diet supplemented with 0, 500, 1000 mg MOE/kg respectively. The BW of sows increased (linear, p ¼ .014) before farrowing; after farrowing and weaning showed both linear and quadratic (p ¼ <.001) effects with the increase in the dose of MOE in the diet. Further, results showed that tendency of reduced (p ¼ .063) BW loss and increased (linear, p ¼ .046) digestibility of dry matter in sows fed with MOE in the diet. The back fat loss and blood profiles were unaffected (p > .05) both in the sows and suckling piglets by the dietary treatment. Dietary inclusion of increasing level of MOE in sows' diet increased (p < .05) BW, average daily gain, faecal score of suckling piglets and reduced the number of diarrheal piglets. Therefore, the addition of MOE can be considered as safe and effective enhancement in both farrowing and lactating sows as it favours the growth, nutrient digestibility and helps in avoidance of diarrhoea among suckling piglets.

“…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). More recently, lactic acid bacteria were proved to be effective in this regard.…”

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.
