Effects of microencapsulated probiotics and prebiotics on growth performance, antioxidative abilities, immune functions, and caecal microflora in broiler chickens

Abstract

The study was conducted to evaluate the effects of microencapsulated probiotics and prebiotics in broilers. A total of 108 one-day-old male Arbor Acres broilers were randomly divided into 3 groups (CON: basal diet; MEP: basal diet + compound microecologic products; ANT: basal diet + antibiotics), and there were 6 replicates per group and 6 birds per replicate. Compared with CON, diets supplemented with MEP or ANT significantly increased average daily gain and serum immunoglobulin M level at day 21, and serum total antioxidant capacity (T-AOC) level at day 42. Compared with CON and ANT groups, birds in MEP group had greater serum T-AOC, immunoglobulin A, interleukin-2 (IL-2) levels, and caecal Lactobacilli counts at day 21, and had greater serum IL-2, interleukin-6 levels, and caecal Lactobacilli counts at day 42. In conclusion, compound microecologic products had beneficial effects on body weight gain, serum immune function, and caecal Lactobacillus counts in broilers, which can be recommended as alternative to antibiotics.

Effects of xylanase and probiotic supplementation on broiler chicken diets

“…The predominance of the Lactobacillales is important since the order contains a variety of microorganisms with probiotic potential. The results of the present study support those of Wang et al (2018), who reported that the Lactobacillales were the most predominant order in the ileal mucosa samples, whereas the Clostridiales were the most predominant in cecal digesta samples. Lactobacillus aviaries were most prevalent in the supplemented group, accounting for 57.16, 70.52, and 36.10% of intestinal microbiota sequences from the xylanase, probiotic, and co-supplemented groups, respectively.…”

Assessment of Refined Functional Carbohydrates as Substitutes of Antibiotic Growth Promoters in Broilers: Effects on Growth Performance, Immune Responses, Intestinal Micro-Flora and Carcass Characteristics

“…Similarly, Abdel-Hafeez et al (2017) reported that feed consumption in the prebiotic group was higher than in control group in broilers. However, Baurhoo et al (2009), Eseceli et al (2010 and Wang et al (2018) reported that feed intake was not influenced by dietary supplementations of AGPs and prebiotics in broilers. The results of the present findings regarding weight gain and FCR are in agreement with the findings of Shahir et al (2014) who reported improved weight gain and FCR in broiler birds fed diet containing yeast based prebiotics.…”

Impact of Prebiotics and Synbiotics Administered in ovo on the Immune Response against Experimental Antigens in Chicken Broilers

“…Many beneficial effects of the dietary application of nondigestible carbohydrates (prebiotics) in poultry have been well-documented [1][2][3][4][5][6]. Inulin fermentation products in the gut have anti-inflammatory effects [7].…”
