“…In this study, the concentration of triglycerides in blood decreased in response to combined treatment with karaya saponin and R. capsulatus. This result agrees with the finding of our previous studies in laying hens in which individual supplementation of karaya saponin (Afrose et al, 2009b) and R. capsulatus (Salma et al, 2007b) decreased serum and meat cholesterol, respectively. Triglycerides are secreted from the liver into the serum by triglyceride-rich lipoproteins; therefore, impaired hepatic lipogenesis results in decreased triglyceride concentration in plasma.…”

“…Although PUFA protects against coronary heart disease by providing more membrane fluidity than MUFA, they are more vulnerable to lipid peroxidation. The present results are similar to our previous reports (Salma et al, 2007b;Tsujii et al, 2008;Afrose et al, 2009c). The increase in oleic acid (C18: 1) observed in this study may have been the result of an enhanced effect of desaturase activity.…”

“…Our previous observations showed that R. capsulatus alone can reduce meat cholesterol in broilers by 19% (Salma et al, 2007b). In this study, we observed a 19% reduction of meat cholesterol with saponin alone, whereas a much higher rate of cholesterol reduction (35%) in meat was obtained when a combination of karaya saponin and R. capsulatus was added to the diet.…”

:Dietary karaya saponin and Rhodobacter capsulatus (R. capsulatus) are known to have hypocholesterolemic actions, as reported in our previous studies. This study examined possible synergistic hypocholesterolemic effects of karaya saponin and R. capsulatus in broilers. A total of 150 broilers were allocated into 10 treatments: control, saponin 25 mg, saponin 50 mg, saponin 75 mg, saponin 25 mg+R. capsulatus 0.2 g, saponin 25 mg+R. capsulatus 0.4 g, saponin 50 mg+R. capsulatus 0.2 g, saponin 50 mg+R. capsulatus 0.4 g, saponin 75 mg+R. capsulatus 0.2 g and saponin 75 mg+R. capsulatus 0.4 g. Feed intake and feed efficiency were improved when karaya saponin and R. capsulatus were synergistically supplemented in the diet. Combinations of karaya saponin, especially supplementation of karaya saponin 50 mg+R. capsulatus 0.4 g were shown to have potential hypolipidemic actions in breast and thigh muscle cholesterol and triglycerides, serum cholesterol, low density lipoprotein-cholesterol and triglycerides, as well as improved high density lipoprotein (HDL)-cholesterol (p<0.05). Compared to the control, almost all the treatments significantly increased serum, liver and fecal concentrations of bile acids (p<0.05). Supplementation of both karaya saponin (75 mg) and saponin 50 mg+R. capsulatus 0.4 g reduced palmitic acid (C16:0) and stearic acid (C18:0) in a similar fashion (p<0.05). The ratios of PUFA:SFA or PUFA+MUFA:SFA in the thigh and breast muscle of broilers were greater in karaya saponin and R. capsulatus supplemented groups than in the control group. Thus, our study concluded that supplementation of karaya saponin synergistically with R. capsulatus in the diet of broilers is an effective way to obtain low-cholesterol, low-triglyceride and high HDL-cholesterol enriched poultry meat with a unique fatty acid balance.

“…The significant improvement of FCR in the RCMP supplementation in the current study additionally might be attributed to the purple non sulphur bacteria (Rhodopseudomonas spp.) as a source of single cell protein (for the poultry industry) (Salma et al, 2007); which have more digestible bacterial cell wall, and are rich in proteins, carotenoids, biological cofactors, and vitamins (Kobayashi and Kurata, 1978).…”

Combinations of probiotic microorganisms are the study of interest due to beneficial impact through synergistic actions. Several researchers including our previous result found positive effects of various combinations of probiotic inclusion in broiler diet. In the current study, the efficacy of combinations of probiotic organisms by adding Rhodopseudomonas spp. was the primary interest on growth performance, mortality, immunity and cecal microflora in broilers. According to the completely randomized design, three hundred day-old Ross broiler chicks (initial BW, 45.08 ± 0.79 g) were randomly allocated to three dietary treatments with ten replications of 10 birds per replicate. Broilers were reared for 5 weeks, where experimental diets were provided for starter (0 to 3 weeks) and finisher (4 to 5 weeks) period. The dietary treatments were, CON = control (corn-soybean meal based basal diet); ABT = basal diet + chlortetracycline-HCl; RCMP = basal diet + multi-microbe probiotic, (Bacillus spp. + Lactobacillus spp. + Saccharomyces spp. + Rhodopseudomonas spp.). Present study revealed that, dietary supplementation of RCMP significantly improved overall average daily gain and feed conversion ratio compared to CON (P<0.05). Mortality rate was significantly reduced in RCMP and ABT supplemented group compared to CON (P<0.05). Serum immunoglobulin level was upgraded after RCMP and ABT supplementation relative to CON but remained nonsignificant (P>0.05). Moreover, cecal pathogenic Escherichia coli and Salmonella was significantly suppressed in RCMP and ABT supplemented group compared to CON (P<0.05); while number of beneficial microorganisms were higher in ABT and RCMP relative to CON but not significant (P>0.05). Thus, dietary supplementation of Rhodopseudomonas-based multi-microbe probiotic (RCMP) has the potentiality to be used as effective feed additives in broilers.

“…Drastic increase of body weight occurs during male sexual maturation, when lipid tissue is known to be accumulated (Salma et al, 2007). The higher lipid in body tissues may be related to the initiation of sexual puberty (Childs et al, 2012).…”

Lipid metabolism in mature male mice may be different from immature male mice, but the relationship of lipid metabolism, especially n-6 fatty acid metabolism, and sexual maturation is not clearly established. This study was carried out to elucidate whether sexual maturation may affect the metabolism of functional n-6 fatty acids of lipid components by investigating the composition of fatty acids in the longissimus muscle tissues of mature and immature male mice with GC and analyzing the expression of genes and proteins for synthesis of n-6 fatty acids with real-time PCR and western blotting, respectively. Mature male mice showed significantly higher testosterone level in the sera. Similarly, n-6 fatty acids, levels of linoleic acid (LA 18:2n-6) and total n-6 PUFA (Polyunsaturated fatty acids) were increased, but the levels of γ-linolenic acid (GLA; 18:3n-6), dihomo-γ -linolenic acid (DGLA; 20:3n-6) and arachidonic acid (AA; 20:4 n-6) were decreased in the mature male mice. mRNA levels of Δ 5-desaturase (FASD1) and elongase (ELOVL5) genes related to n-6 fatty acid metabolism increased. However, the level of FADS1 protein only increased in mature male mice. In conclusion, this study suggested that sexual maturation of male mice affected n-6 fatty acid metabolism by stimulating the expression of enzyme FADS1 of n-6 PUFA metabolism.
