Dietary Components

A 5 × 5 Latin square experiment utilizing mature wethers (78 kg) was conducted to investigate the effects of feeding combinations of alkaline hydrogen peroxide-treated wheat straw (AHP-WS) and alfalfa hay on intake and nutrient digestibility. Diets consisted of an 80:20 forage to concentrate ratio on a dry matter (DM) basis. Dietary designations were based on ratios of AHP-WS: alfalfa hay in the diet. Quadratic responses (P < 0.05) were noted for both DM intake (DMI) as a percentage of body weight and organic matter intake (OMI) expressed as g d−1. Greater DMI and OMI were noted when wethers were fed diets containing combinations of AHP-WS and alfalfa (40:40 and 20:60) than when fed those containing AHP-WS or alfalfa as the sole forage (80:0 or 0:80). No effects of diet on digestibilities of dietary components were observed, with digestibility of DM and OM averaging 67 and 69%, respectively, across diets. Wethers consumed greater amounts of digestible OM when fed combinations of the two forages than when either was fed alone. Molar proportions of all ruminal volatile fatty acids (VFA) except acetate responded in a quadratic (P < 0.05) manner due to diet. Molar proportion of propionate decreased while molar proportions of other VFA increased with increasing level of alfalfa. Ruminal liquid and particulate dilution rates were not affected by diet. Time spent ruminating by sheep was increased linearly (P < 0.05) by inclusion of alfalfa hay in the diet. Favorable comparisons of AHP-WS to high quality alfalfa hay demonstrate the effectiveness of the AHP treatment process to enhance the nutritive value of WS.

Chaudhry and Miller (1993) have demonstrated the effectiveness of Alkaline hydrogen peroxide (AHP) in improving in vitro digestibility (IVD) of cereal straws. Further experiments were conducted to evaluate the use of AHP on a larger scale compared with varying amounts of sodium hydroxide (NaOH) in improving the nutritive value of wheat straw (WS) for sheep.

Background and Aim: Crude glycerin is changed to propionate in the rumen, while chitosan can be used as a feed supplement to increase propionic acid concentration and decrease methane (CH4) production. We hypothesized that supplementation with a combination of a high level of crude glycerin with chitosan could have a beneficial effect on ruminal fermentation and mitigate CH4 production. This study aimed to explore the combined effects of crude glycerin and chitosan supplementation on nutrient digestibility, rumen fermentation, and CH4 calculation in native Thai bulls. Materials and Methods: Four 2-year-old native Thai bulls, weighing 150±20 kg, were kept in a 2×2 factorial arrangement in a 4×4 Latin square design. Factor A represented the incorporation of crude glycerin at 10.5% and 21% of the dry matter (DM) of a total mixed ration (TMR), and factor B represented the supplementation of chitosan at 1% and 2% DM of a TMR. Results: Increasing levels of crude glycerin at 21% decreased DM intake by 0.62 kg/day compared with 10.5% crude glycerin (p<0.05), whereas nutrient digestibility did not change (p>0.05). The incorporated crude glycerin and supplemented chitosan levels did not affect the pH, temperature, concentrations of ammonia-nitrogen, microbial population, and blood urea nitrogen (p>0.05). Supplemented chitosan and incorporated crude glycerin did not show any interaction effects on the molar portions and total volatile fatty acids (VFAs), except estimated CH4. Increasing the incorporated crude glycerin levels increased propionate and decreased the ratio of acetate to propionate ratio, whereas levels of butyrate, acetate, and total VFAs were unchanged. The combination of crude glycerin at 21% in the TMR with chitosan at 2% reduced CH4 estimation by 5.08% compared with the other feed treatment. Conclusion: Increasing incorporated crude glycerin levels in a TMR significantly elevated the propionate concentration, whereas combining 21% crude glycerin in the TMR diet with 2% chitosan supplementation could depress CH4 estimation more effectively than adding one of these supplements alone.

Environmental concerns due to excessive use of synthetic or petroleum-based materials have encouraged scientists to develop novel, sustainable, and multifunctional material using abundant lignocellulosic biomass. In this work, a study was conducted on the isolation of cellulose from wheat straw using two different methods: acidified sodium chlorite and alkaline hydrogen peroxide. A comparative study was carried out based on the yield and properties of extracted cellulose. The final product (after treatments) was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) for the identification of properties. Both the treatments isolated pure white color cellulose. However, the yield of cellulose isolated through acidified sodium chlorite treatment (81.4%) was higher than alkaline hydrogen peroxide treatment (79%). Moreover, no huge difference was observed in the crystallinity and thermal properties of extracted cellulose.

AbstractA 5 ✕ 5 Latin square was conducted with ruminally and duodenally cannulated Dohne Merino wethers consuming wheat straw to determine the effect of different rumen degradable protein (RDP) levels on forage intake, fermentation characteristics, nutrient flow and digestion. The wethers had ad libitum access to water and wheat straw (32 g crude protein (CP) per kg dry matter (DM); 742 g neutral-detergent fibre (NDF) per kg DM) that was offered twice daily, immediately after intraruminal infusion of the supplements at 07:00 and 19:00 h. The supplemental RDP (calcium caseinate; 900 g CP per kg DM) levels were: 0, 40, 80, 120 and 160 g/day. Each period consisted of 14 days of adaptation and 6 days of sampling. Forage and total organic matter (OM) intakes increased in a linear manner (P < 0•01) with increasing supplemental RDP levels. Digestible organic matter intake (DOMI) displayed a quadratic increase with elevated amounts of RDP (P < 0•01). The effects of treatments on rumen and total tract digestion, as well as fluid dilution rate were minimal. Microbial nitrogen (MN) flow to the duodenum and microbial efficiency increased quadratically (P < 0•04) with increased RDP supplementation. Rumen ammonia nitrogen (NH3-N) concentrations increased linearly (P < 0•01) and total volatile fatty acids (VFA) tended to increase linearly (P = 0•07). In conclusion, RDP supplementation to Dohne Merino wethers consuming wheat straw generally enhanced rumen fermentation and forage intake. A total RDP intake (sources: calcium caseinate and wheat straw) of 3•30 g/kg M0•75 or 0•12 of DOM maximized DOMI.

Farm Scale

That alkali treatments can improve the nutritional quality of poor quality roughages has long been established (Sundstol and Owen, 1984). However, their effectiveness is limited by their potential hazards to the animals and mankind. Alkaline hydrogen peroxide (AHP) has recently emerged as a possible substitute (Gould, 1985) but its farm scale application is limited by the need for high amounts of chemicals and water. Lack of any information regarding its effectiveness over NaOH alone is another factor which requires further investigation. The present study was, therefore, planned to assess the effectiveness of pH-regulated (11.5±0.2) H2O2 (AHP) in improving the in vitro dry matter digestibility (IVDMD) of wheat straw (WS, Avalon) under different laboratory conditions. The possibility of using CaO on its own or to regulate pH for AHP was also tested.
