We aimed to investigate the effects of Clostridium butyricum-, Bacillus subtilis-, and Bacillus licheniformis-based potential probiotics on the growth performance, intestinal morphology, immune responses, and caecal short chain fatty acids (SCFAs) and microbial structure in broiler chickens. Three treatment groups containing a total of 1200 one-day-old AA broilers were included: birds fed with a basal diet only (Con), birds fed with added 1010 probiotics cfu/kg (ProL), and birds fed with added 1011 probiotics cfu/kg (ProH). The dietary probiotics significantly improved the final and average body weights and serum immunoglobulins A, M, and Y. The probiotics also enhanced the ileal morphology and improved the caecal acetate, butyrate, and propionate contents. Furthermore, 16S rRNA sequencing revealed that dietary compound probiotics modulated the caecal microflora composition as follows: (1) all birds shared 2794 observed taxonomic units; (2) treatment groups were well separated in the PCA and PCoA analysis; (3) the relative abundance of Parabacteroides, Ruminococcaceae_UCG-014, Barnesiella, Odoribacter, [Eubacterium_coprostanoligenes_group], [Ruminococcus]_torques_group, and Butyricimonas significantly varied between treatments. The compound probiotics improved the growth performance, serum immune responses, the ratio of ileal villus height to crypt depth, and major caecal SCFAs in broiler chickens. The dietary C. butyricum-, B. subtilis-, and B. licheniformis-based probiotics improved overall broiler health and would benefit the poultry industry.

Seed Extracts

Grape seed is rich in vitamin E, flavonoids, and proanthocyanidins and has the potential to be used as an antibiotic substitute in broilers. We investigated the effects of grape seed proanthocyanidin extract (GSPE) on growth performance, immune responses, cecal microflora, and serum metabolism in early stage broilers. Data indicated that GSPE improved broiler growth performance by strengthening antioxidant capacity, enhancing immune responses, and increasing cecal short chain fatty acids. 16S rRNA sequencing indicated that GSPE changed the predominant cecal microflora and induced the metabolism of amino acids, lipids, and carbohydrates. An UPLC-Q-TOF/MS-based metabolomics analysis identified 23 serum metabolites (mainly related to lipid, amino acid, and alkaloid) were extremely changed by GSPE treatment. The correlations between the changes of cecal microflora and serum metabolites in birds fed with GSPE were analyzed. Hence, GSPE potentially provides active ingredients that may be used as antibiotic substitute and reduces environmental pollution by grape by-products.

Abstract. A study was conducted to investigate the capability of Myrtus communis essential oil (MCE) in counteracting the deleterious effects of aflatoxin B1 (AFB1) on growth performance, serum biochemistry and humoral immune responses in broiler chickens. In a completely randomized design, 300 day-old male chicks were assigned to four treatments with five replicates of 15 birds for 42 days. Chickens, up to day 7 of age, were fed the same diet and then, they were fed the experimental diets. The dietary treatments were 1) the negative control (no dietary aflatoxin or MCE), 2) the positive control (diet containing AFB1 at 0.5 mg/kg, without MCE), 3) diet containing AFB1 at 0.5 mg/kg plus 500 mg/kg MCE, and 4) basal diet containing 500 mg/kg MCE, without AFB1. Growth performance was measured from day 7 to 42. Serum biochemical parameters, organ weights on day 42 and the antibody titers against Newcastle and influenza viruses on day 28 of age were determined. Addition of aflatoxin to diet decreased (P<0.05) the weight gain and feed intake and MCE supplementation diminished (P<0.05) the inhibitory effects of AFB1 on the growth performance. Addition of AFB1 to diet of chicks increased the serum activities of aspartate aminotransferase (AST), alkaline aminotransferase (ALT), alkaline phosphatase (ALP), and decreased the antibody titers against Newcastle and influenza viruses. Addition of MCE to diet alleviated the negative effects of AFB1 on these parameters (P<0.05). In conclusion, our results showed that addition of MCE may reduce the adverse effects of AFB1 on broiler chickens.
