“…The total liver carotenoid levels in the canthaxanthin treatment group were also significantly higher than those in the Lutein Bead and Lyco Bead treatment groups (p<0.05). The finding that canthaxanthin accumulates at higher rates than other synthetic red pigments is consistent with reports in the literature (Klasing, 1998;Waldenstedt et al, 2003). Vitamin E supplementation was found to significantly increase the liver vitamin E concentrations (p<0.05); however, the different antioxidant treatments did not significantly affect the liver coenzyme Q 10 levels (Table 6).…”

This study investigated the effects of the addition of different antioxidants to broiler diets on their live performance, liver antioxidant composition and concentrations, immune response, and meat and skin color. A total of 945 three-day-old Ross 308 broiler chicks of both genders were randomly allocated to one of nine dietary treatments (n=105), with three replicates 35 chicks per pen, as follows: T1: control (commercially available corn-and soybean-based broiler diet); T2: selenium (control+0.5 mg/kg Sel-Plex TM Se yeast); T3: vitamin E (control+200 mg/ kg Kavimix-E-50 α-tocopherol acetate); T4: lutein (control+100 mg/kg 5% Lutein Beads XB); T5: lycopene (control+100 mg/kg 5% Lyco Beads XB);T6: canthaxanthin (control+25 mg/kg 10% Carophyll . Feed (starter, grower, developer and finisher phases) and water were provided ad libitum for 42 days. Body weights, feed intake, feed conversion values and plasma carotene concentrations were recorded weekly, and liver antioxidant concentrations were recorded at the end of the experiment. Newcastle disease (LaSota) vaccination was performed on day 22. HI titers were measured on days 14, 21, 35 and 42 to determine the effects of the antioxidants on the immune system.The addition of selenium, vitamin E, and carotenoid supplements to the commercial broiler diet significantly increased antioxidant accumulation in the liver and the plasma. All antioxidants assessed significantly improved the immune response. Selenium and vitamin E supplementation also significantly improved total carotenoid concentrations in the plasma. The carotenoids enhanced skin and meat color. None of the supplements tested influenced growth (p>0.05).

“…Enteritidis ATCC 13076 (Demiriz et al 2011). Waldenstedt et al (2003) studied the antibacterial effect of the carotenoid astaxanthin produced by the microalga Haematococcus pluvialis (Chlorophyceae) on C. jejuni and C. perfringens in the GIT of chickens. An in vivo experiment reported that the counts of C. jejuni remained unchanged and that the counts of C. perfringens decreased significantly (Waldenstedt et al 2003); however, our in vitro findings were the opposite.…”

ABSTRACT:The green alga Planktochlorella nurekis (Chlorellaceae, Chlorophyta) is considered a producer of antibacterial mixture of long-chain fatty acids, which has possibly similar composition and mode of action as chlorellin produced by another green alga, Chlorella vulgaris. Although the antibacterial properties of C. vulgaris have been reported, the interactions of P. nurekis with bacteria have not been determined yet. The aim of this study was to elucidate the effect of P. nurekis water suspension on growth of selected gastrointestinal bacteria in vitro so that it could be used as a suitable feed supplement in animal farming. Unknown bacterial populations occurring in the algal suspension were identified using 16S rRNA sequencing assay. Selected strains were cultivated with lyophilized P. nurekis and the antibacterial effect was monitored. The composition of fatty acids and heat sensitivity of antibacterial substances were also examined. Sequencing analysis of 71 bacterial 16S rRNA genes in xenic algal suspension identified common environmental microbiota, one strain belonging to the class Alphaproteobacteria, 17 to Betaproteobacteria, 44 to Gammaproteobacteria (dominated by Pseudomonas putida strains), and nine to Sphingobacteria. The antimicrobial activity of P. nurekis suspension was tested at a concentration range of 0.75-6 mg/ml. The highest inhibitory effect was observed on bifidobacteria. Statistically significant reductions in bacterial counts were also observed for Escherichia coli, Salmonella enterica var. Enteritidis, S. enterica var. Infantis, Campylobacter jejuni, and Arcobacter butzleri. The growth of Lactobacillus johnsonii was significantly stimulated. The relative proportions of C14-C22 fatty acids in P. nurekis were found as follows: saturated 54.28%, monounsaturated 30.40%, and polyunsaturated 7.16%. The antibacterial compounds present in P. nurekis suspension exhibited thermostability. The results indicate that P. nurekis can inhibit some pathogenic gastrointestinal bacteria and seems to be a promising essential nutrients source in animal nutrition.
