Abstract Background The development and utilization of probiotics had many environmental benefits for replacing antibiotics in animal production. Bacteria in the intestinal mucosa have better adhesion to the host intestinal epithelial cells compared to bacteria in the intestinal contents. In this study, lactic acid bacteria were isolated from the intestinal mucosa of broiler chickens and investigated as the substitution to antibiotic in broiler production. Results In addition to acid resistance, high temperature resistance, antimicrobial sensitivity tests, and intestinal epithelial cell adhesion, Enterococcus faecium PNC01 (E. faecium PNC01) was showed to be non-cytotoxic to epithelial cells. Draft genome sequence of E. faecium PNC01 predicted that it synthesized bacteriocin to perform probiotic functions and bacteriocin activity assay showed it inhibited Salmonella typhimurium from invading intestinal epithelial cells. Diet supplemented with E. faecium PNC01 increased the ileal villus height and crypt depth in broiler chickens, reduced the relative length of the cecum at day 21, and reduced the relative length of jejunum and ileum at day 42. Diet supplemented with E. faecium PNC01 increased the relative abundance of Firmicutes and Lactobacillus, decreased the relative abundance of Bacteroides in the cecal microbiota. Conclusion E. faecium PNC01 replaced antibiotics to reduce the feed conversion rate. Furthermore, E. faecium PNC01 improved intestinal morphology and altered the composition of microbiota in the cecum to reduce feed conversion rate. Thus, it can be used as an alternative for antibiotics in broiler production to avoid the adverse impact of antibiotics by altering the gut microbiota. Graphic Abstract

Reasonable Proportion

While vitamins naturally occurring in plant and animal based feed ingredients can supply a reasonable proportion of the birds daily needs, their contribution is rarely considered during formulation. This situation arises due to variability, especially in cereals and vegetable proteins, for example, the vitamin E content of corn can vary from 10 to 40 IU/kg. Because of this uncertainty in the natural supply of vitamins within a feed, the bird’s vitamin supply is therefore met by the addition of synthetic vitamins, usually in the form of a so called premix, that contains all vitamins and perhaps some other micronutrients and feed additives. This premixes use according to producer suggestions and in some cases their doses can be higher than real requirements. Skinner et al (1992) removed vitamin premixes from 21 day of age and did not report any adverse effects. Gwyther et al (1992) showed sever performance reduction by vitamin premix withdrawal from 21 to 49 day of age. This experiment was conducted to determine the effects of Vitamin supplement levels on broiler chickens from 28 to 49 days of age.

Dietary Treatments

An experiment was conducted to compare the effect of dietary sodium selenite and selenomethionine on selenium and α-tocopherol concentration in breast meat, oxidative stability of meat in broilers, and on growth performance, but only as an unimportant criterion in this case. Sexed broiler cockerels Ross 308 were allocated to 3 dietary treatments, each comprising 100 chickens. The basal diet was supplemented with 0 (control) or 0.3 mg/kg Se from sodium selenite (SS) or selenomethionine (SM). Dietary supplementation with SM increased (<I>P</I> < 0.05) body weight, but only by about 3%. Breast muscle Se concentration was increased (<I>P</I> < 0.05) by both Se sources, but more by SM (1.32 mg/kg dry matter; 0.47 mg/kg DM in control). The concentration of Se in excreta was 3 times higher with SS supplement than with SM supplement. Dietary Se supplementation increased (<I>P</I> < 0.05) the α-tocopherol content of breast meat from 25.9 mg/kg DM in the control to 33.2 mg/kg DM when SM supplementation was used. Furthermore, lipid peroxidation decreased compared to the control. The inclusion of SM in the diet reduced (<I>P</I> < 0.05) malondialdehyde (MDA) values in breast samples after 0, 3, and 5 days of cooler storage, whereas SS decreased (<I>P</I> < 0.05) the MDA of breast meat after 0 and 3 days of storage. The results of this experiment indicate that selenomethionine in the diet of broilers is capable of simultaneously increasing the content of selenium and vitamin E in broiler meat plus its stability in storage.
