Sugar beet pulp is an abundant industrial waste material that holds a great potential for bioethanol production owing to its high content of cellulose, hemicelluloses, and pectin. Its structural and chemical robustness limits the yield of fermentable sugars obtained by hydrolyzation and represents the main bottleneck for bioethanol production. Physical (ultrasound and thermal) pretreatment meth...

Two experiments were conducted to evaluate the effects of increasing concentrations of glycerol in concentrate diets on total tract digestibility, methane (CH4) emissions, growth, fatty acid profiles, and carcass traits of lambs. In both experiments, the control diet contained 57% barley grain, 14.5% wheat dried distillers grain with solubles (WDDGS), 13% sunflower hulls, 6.5% beet pulp, 6.3% a...

This experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. A completely randomized design with six treatments and six replicates was used.The six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...

Indigestible neutral detergent fibers (iNDF) accurately predict forage digestibility when measured in situ. The objective of this study was to determine the effects of rumen incubation times on the estimated concentrations of iNDF for four forages (alfalfa hay, corn silage, wheat straw and orchard grass), four concentrates (barley grain, soybean meal, beet pulp and wheat bran) and two ...

The aim of present study is investigating effect of treated lemon pulp by Saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. In this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by Saccharomyces cerevisiae yeas...

The wood of a mature (40-year-old) Eucalyptus globulus Labill tree was characterized at different stem height levels (0%, 10%, 35%, and 50% of total height) regarding pulping, bleaching, and paper properties. Pulp yields increased upwards from 46% to 50%, and Kappa number decreased from 17.5 to 12.3 at 0 and 50% height, respectively. The estimated specific wood consumption ranged from 3.2 m odt...

The aim of this study was to investigate the applicability sugar beet pulp (SBP) in particleboard production as a substitute for wood material. Two variants board density, 650 kg/m3 and 550 kg/m3, containing 0%, 25% 50% SPB, were evaluated. During following features measured: modulus rupture (MOR), elasticity (MOE), thickness swelling (TS) water absorption (WA). results showed that boards up SB...

Effects of Adding Different Levels Date Pulp on the Aerobic Stability, Degradability Parametrs and Nutritional Value Alfalfa Silage using Gas Production

BACKGROUND Pectin-rich wastes, such as citrus pulp and sugar beet pulp, are produced in considerable amounts by the juice and sugar industry and could be used as raw materials for biorefineries. One possible process in such biorefineries is the hydrolysis of these wastes and the subsequent production of ethanol. However, the ethanol-producing organism of choice, Saccharomyces cerevisiae, is not...

We proposed an hypothesis that ruminants attempt to select a diet that promotes high levels of feed intake by maintaining optimal ruminal conditions. Three tests of the hypothesis considered whether the diet selection of sheep given either a choice of two high energy density (ED) feeds or a choice between a high and a low ED feed is affected by 1) sodium bicarbonate inclusion (NaHCO3; 1, 2, and...
