In the present work, a continuous process was developed for the production of advanced biobased hydrogen enriched methane, from crude glycerol in a two-stage reactor system. In the first step, biohydrogen production was studied, using attached mixed acidogenic consortia in an up-flow column bioreactor. Cylindrical ceramic beads with porosity corresponding to 600 mL were used as attachment matri...

This study was designed to detemine if conjugated linoleic acid (CM) is incorporated into egg lipids through dietary CLA supplernentation. Forty Single Comb White Leghorn layen (28 weeks of age) were randomly assigned into four treatments of varying CLA levels, 0, 0.01, 0.5 and l g C W k g diet. C U replaced an equivalent arnount of linoleic acid in the diet. Eggs were collected over 36 days. F...

The effects of recombinant bovine growth hormone (rbGH; PosilacR) on growth rate, feed efficiency, body composition, and insulin-like growth factor binding proteins (IGFBPs) were investigated in Norris and NWAC103 strains of channel catfish. Three hundred and twenty fish from each strain were assigned randomly to four treatments with four replicates each. The treatments were (1) Sham-injected c...

The effects of feeding farm-raised mink (Mustela vison) diets containing polychlorinated biphenyl (PCB)-contaminated fish from the upper Hudson River (New York, USA) on adult reproductive performance and kit growth and mortality were evaluated. Diets contained 2.5 to 20% Hudson River fish, providing 0.72 to 6.1 µg ∑PCBs/g feed (4.8-38 pg toxic equivalents [TEQWHO 2005 ]/g feed). The percentage ...

A study was conducted to evaluate the effects of an artichoke extract on broiler production performance traits by comparing the results of two inclusion rates in broiler diets from 0 to 21 days of age. A total of 2880 day-old male broiler chicks was randomly assigned to 36 floor-pens and raised from 1 to 42 days of age. The CONTROL group received a comsoya meal basal diet. In the treatment diet...

The aim of our study was to determine the efficacy of three different adsorbents, inorganic (modified zeolite), organic (esterified glucomannans) and mixed (inorganic and organic components, with the addition of enzymes), in protecting broilers from the toxic effects of ochratoxin A in feed. Broilers were fed diets containing 2 mg/kg of ochratoxin A (OTA) and supplemented with adsorbents at the...

With old age, blood flow to the high-oxidative red skeletal muscle is reduced and blood flow to the low-oxidative white muscle is elevated during exercise. Changes in the number of feed arteries perforating the muscle are thought to contribute to this altered hyperemic response during exercise. We tested the hypothesis that exercise training would ameliorate age-related differences in blood flo...

An experiment was conducted to evaluate the effects of supplementing black cumin (Nigella sativa) seeds (BCS) in diet on performance, liver weight and enzymes of broilers.The experiment was conducted as a randomized complete block design. Two hundred forty day-old unsexed broiler chicks (Cobb 500) were divided into four groups and assigned to four feeding treatments, with four replicates of 15 ...
