Effects of Dietary Supplementation of Fermented Rice Bran (FRB) or Fermented Broken Rice (FBR) on Laying Performance, Egg Quality, Blood Parameter, and Cholesterol in Egg Yolk of Hy-Line Brown Laying Hens

Abstract

This experiment was aimed at investigating the effects of dietary supplementation with fermented rice bran (FRB) or fermented broken rice (FBR) on egg-laying performance, egg quality, blood parameters, and cholesterol level in egg yolk of Hy-Line Brown egg-laying hens. Altogether, 144 Hy-Line Brown egg-laying hens (32-week-old) were randomly allocated to one of 4 dietary treatment groups, with 4 replicates per treatment. Of them, 3 treatments diets were prepared by supplementing the basal diet with 0.1% probiotics (PRO), 1% fermented rice bran (FRB), or 1% fermented broken rice (FBR) at the expense of corn. Hen-day egg production was higher (P<0.05) in PRO and FRB treatment groups than in the basal treatment groups. However, feed intake, egg weight, egg mass, and feed conversion ratio did not differ among the treatment groups. Additionally, supplementation with FRB or FBR did not affect eggshell strength, eggshell thickness, egg yolk color, and Haugh unit during the feeding trial. There was no significant difference in leukocyte count. Total cholesterol level was lower (P<0.05) in the FRB treatment group than in the basal treatment groups. Asparate aminotransferase, alanine transferase, glucose, and albumin levels were unaffected by dietary supplementation with FRB or FBR. Egg yolk cholesterol level was lower (P<0.05) in the FRB and FBR treatment groups than in the basal treatment groups. In conclusion, dietary supplementation with FRB or FBR improved egg-laying performance, and reduced the levels of total serum cholesterol and cholesterol in egg yolk of Hy-Line Brown egg-laying hens.(Key words: Hy-Line Brown laying hens, laying performance, fermented rice bran, fermented broken rice, total cholesterol) † To whom correspondence should be addressed : magic100@korea.kr

An Animal Study to Compare Hepatoprotective Effects Between Fermented Rice Bran and Fermented Rice Germ and Soybean in a Sprague-Dawley Rat Model of Alcohol-Induced Hepatic Injury

“…Moreover, we found that the FRB might be more effective in lowering ALDH levels at a concentration of 15% compared with the FRS. These results are in agreement with previous studies [64,65,67,70,79,[95][96][97].…”

“…Our results indicate that the FRB might be more effective in lowering serum levels of AST, ALT and ALP at a concentration of 15% and those of LDH at a concentration of 30% compared with the FRS. This is in agreement with previously published studies showing that the FRB had a positive effect on serum levels of hepatic enzymes [30,31,[64][65][66][67][68][69][70][71][72][73].…”

Effect of Dietary Zeolite Supplementation on Production, Egg Quality, Ammonia Volatilization, Organ Morphometry and Blood Parameters in Brown Laying Hens

“…Blood profile parameters are indicators of the physiological, pathological, and nutritional status of animals. In this respect, changes in hematological variables are indicators to be used to elucidate the impact of nutritional factors, which are present in the diet fed to the birds (Kim et al, 2017). B and T lymphocytes are considered the defense mechanisms, and, together with antibodies and lymphokines, they form the immune response.…”

Pilot Study of Diet Supplemented with Sold-Out Substrate of Pleurotus ostreatus in the Feeding of Backyard Broilers

“…Inclusion of sold-out substrate in the feed helps to reduce the cholesterol content in the blood. A study conducted by Kim et al [57] found low concentrations of cholesterol in the group fed by fermented rice bran than in the control group for laying hens. Wang et al [58] reported that fermented food helps to inhibit the activity of 3-hydroxy-3-methylglutaryl-CoA reductase, which reduces cholesterol biosynthesis.…”
