Analysis of the effect of dietary protected organic acid blend on lactating sows and their piglets

Abstract

-The objective of the present study was to evaluate the effects of blends of dietary protected organic acid supplementation on growth performance, nutrient digestibility, blood profiles, faecal microflora, and gas emission on sows and piglets with emphasis on their modes of action to improve pig performance. A total of 12 sows with an average initial body weight (BW) of 252.40±11.7 kg were used in this trial. Growth performance, blood profiles, and nutrient digestibility of sows and piglets fed protected organic acid were evaluated. The dietary treatments included a basal diet (CON); CON + 0.1% protected organic acid; and CON + 0.2% protected organic acid. The BW and back fat of sows was checked four days prior to farrowing and at the weaning day to calculate BW loss and back fat loss during that period. Inclusion of 0.2% protected organic acid provided a greater digestibility than CON diets throughout the experimental period in lactating sows. Dietary supplementation with 0.2% protected organic acid led to a higher white blood cell and lymphocyte concentration than CON treatment in sucking piglets. Immunoglobulin G concentration observed was greater in protected organic acid groups in lactating sow and sucking piglets. Increased faecal Lactobacillus counts with decreased E. coli concentrations were observed with the diets of protected organic acid fed to lactating sows. The E. coli counts were decreased in weaning piglets. The faecal H 2 S contents were decreased in 0.2% protected organic acid diets during farrowing on day 1. Dietary supplementation with protected organic acid blends beneficially affects the nutrient digestibility, ileal noxious gas (NH 3 and H 2 S) emission, as well as intestinal microbial balance in lactating sows.

Evaluation of the effectiveness of supplementing micro-encapsulated organic acids and essential oils in diets for sows and suckling piglets

“…In the present study, DM digestibility was increased with MOE supplementation which was consistent with the findings by Kluge et al (2010) and Mohana Devi et al (2016) reported that the inclusion of 2% benzoic acid and protected organic acid blends respectively in the diet of lactating sows improved the digestibility of nutrients. Similarly, Bolduan et al (1988), Jongbloed & Jongbloed (1996) found that dietary supplementation of OA increased the ATTD of DM, but not in organic matter.…”

“…Similarly, Cho et al (2014) reported that the addition of 0.05% MOE in diet of pigs improved growth performance and 3 kg/ton AviplusV R added to weaned piglet diets increased ADG (from d 15 to d 41) and at the end of study (Grilli et al 2010). Dietary MOE supplemented sows were significantly effective on BW change and the relevant result of effect was tendency to reduction of body weight loss in lactation period, which result consistent with Mohana Devi et al (2016) reported that the effect of dietary supplement with protected organic acids on reproductive performance in sows. This perhaps is a consequence of improved intake and utilisation of food supplements with no relationship with sow back fat loss during lactation as suggested with previous reports (Ilsley et al 2003;Matysiak et al 2012;Kingori 2012;Chengquan et al 2015;Hossain et al 2015).…”

“…This study showed that losses of backfat and weaning to oestrus interval during experimental period showed no effects in the MOE-treated sows. Likewise, Ilsley et al (2003) and Mohana Devi et al (2016) found that had no significant effect on the loss of backfat during lactation among sows.…”

“…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).…”

Organic acids in piglet nutrition – a review

“…Dzięki temu kwasy uwalniane są dopiero w jelitach, gdzie skutecznie redukują patogenne bakterie. Wyniki badań wskazują również, że zastosowanie kwasów chronionych poprawiło znacznie wskaźniki wzrostu, strawność substancji odżyw-czych oraz ograniczyło powstawanie amin biogennych w jelicie grubym, a także uwalnianie amoniaku i siarkowodoru z kału (8,41).…”
