Effects of mannanoligosaccharide and/or organic acid mixture on performance, blood parameters and intestinal microbiota of broiler chicks

Abstract

The experiment was conducted to evaluate the effects of organic acid mixture and/or mannanoligosaccharides (MOS) on growth performance, blood parameters and intestinal microbiota in 120 Ross 308 male broiler chicks, over a period of 21 days. Birds were maintained in battery brooders confined in an environmentally controlled experimental room. There were 4 dietary treatments, each consisting of 6 replicates. Dietary treatments were: (i) basal diet (as a control), (ii) basal diet + MOS 2 kg/ton feed, (iii) basal diet + organic acid mixture 3 kg/ton feed and (iv) basal diet + MOS 2 kg/ton feed + organic acid mixture 3 kg/ton feed. Weight gain of the broilers in this study was significantly influenced by the addition of organic acid mixture (P<0.01). The lowest feed intake and feed conversion ratio (FCR) were detected in the MOS supplemented groups (P<0.05). Erythrocyte length (EL) was significantly increased in MOS + organic acid mixture fed groups (P<0.05). In ileal digesta, lactic acid bacteria counts increased in MOS + organic acid mixture fed groups (P<0.001). Otherwise, E. coli counts decreased in MOS, organic acid mixture and MOS + organic acid mixture fed groups compared to control groups (P<0.001). In caecal digesta, lactic acid bacteria counts increased (P<0.001), whereas E. coli numbers decreased compared to control groups (P<0.001)

Combined supplementation of organic acid blend and mannanoligosaccharide suppresses expression of heat shock protein 70 in broilers

“…Increased yeast in GIT is good for better digestion of dry matter and crude fiber (Bagheri et al, 2009). Combined supplementation of MOS and OAB increased counts of LAB and yeast which are in line to the findings of Ozduven et al (2009). Similar effects have been documented by many scientists (Sohail et al, 2013).…”

“…The first group (CONT) was kept as control and was fed basal diet (Table 1). The second group (MOSG) and third group (OABG) were supplemented with MOS (Actigen®-Alltech Lexington, UK, 2gm/kg of basal diet) and OAB (Acid Lab -Pulse, Wuzburg, Germany, 3gm/kg of basal diet) respectively whereas, the fourth group (MOS+OAB) was given combination of both MOS and OAB (2gm and 3gm respectively per kg of basal diet) (Ozduven et al, 2009). The OAB contained formic acid 16.84%, ammonium formate 9.25%, lactic acid 33.60%, propionic acid 5.05% and sodium chloride 35.26 %.…”

“…Ltd. Mumbai, India) for yeast were used. Counts of LAB and yeast after four days of incubation at 30°C were recorded and converted to logarithmic colony forming units (cfu/g) (Ozduven et al, 2009).…”

“…Very few experiments have been conducted which divulge about the synergistic effects of organic acid blend (OAB) along with MOS (Ozduven et al, 2009) and to the best of our knowledge no data is present regarding the expression of heat shock protein (HSP) 70 after feeding combination of OAB and MOS. Therefore, this study aims at investigating the single and combined effects of OAB and MOS small intestine microflora and expression of HSP 70 in broilers.…”
