Crude glycerin is a co-product from biodiesel production. In 2006, approximately 250,000 million gallons of biodiesel were produced, which translates to 75,000 metric tons of glycerin. Glycerin contains approximately 3,650 kcal/kg of gross energy and, as such, it may be a potential dietary energy source for poultry. Three energy balance experiments were conducted to determine AMEn of glycerin u...
INTRODUCTION Glycerin is a rare sensitizer and is widely used for cosmetics, medicine, and food for its stable, nontoxic properties. We report on a patient with generalized urticarial eruptions who had contact urticaria syndrome caused by glycerin enema. Our case suggests that glycerin can be a cause of contact urticaria syndrome and even anaphylaxis, although allergic reactions to glycerin are...
Three energy balance experiments were conducted to determine AMEn of glycerin using broiler chickens of diverse ages. In experiment 1, two dietary treatments were fed from 4 to 11 d of age. Dietary treatments consisted of a control diet (no added glycerin) and a diet containing 6% glycerin (94% control diet + 6% glycerin). Four dietary treatments were provided in experiment 2 (from 17 to 24 d o...
An increasing number of countries and areas in the world suffer from either natural or anthropogenic dust, which results in a serious hazard with respect to the environment and to personal health and safety. This paper reviews and summarizes open literature involving the use of glycerin in dust control applications. Glycerin, a by-product from biodiesel manufacturing, has been evaluated for dus...
Objectives/Goals This project was designed to determine how varying the amount of a specific ingredient that constitute a bioplastic mixture can affect tensile strength. I hypothesized that if more glycerin is added to a mixture of cornstarch, water, vinegar, and glycerin, then a bioplastic with increased tensile strength and flexibility will be produced. Methods/Materials Mold, 40 bioplastics ...
An energy balance experiment was conducted to determine the AME(n) of various crude glycerin samples, and to generate an equation to predict AME(n) of crude glycerin based on its chemical composition. Dietary treatments consisted of a corn-soybean meal basal diet with no added glycerin and a basal diet supplemented with 6% glycerin. Crude glycerin samples were obtained from biodiesel production...
The energy value of crude glycerin from different biodiesel production facilities was determined in nursery pigs (initial BW of 10.4 kg) to predict apparent DE and ME based on the composition of crude glycerin. Dietary treatments consisted of a basal diet, or diets containing crude glycerin from various biodiesel production facilities supplemented in the diet at approximately 9.1%. Because of b...
Crossbred heifers (n = 373; 421.6 kg +/- 28.9) were fed finishing diets containing 0, 2, 4, 8, 12, or 16% crude glycerin (DM basis). Diets consisted of steam-flaked corn with 6% alfalfa hay and 1.2% urea and provided 300 mg of monensin, 90 mg of tylosin, and 0.5 mg of melengestrol acetate per animal daily. Cattle were stratified by BW and allocated randomly, within strata, to concrete-surfaced ...
The objective of this study was to evaluate the effect of crude glycerin inclusion levels on BRS Capiaçu grass (Pennisetum purpureum) silage on the parameters of fermentation and chemical-bromatological composition. Experimental treatments consisted of BRS Capiaçu grass silage with five levels of inclusion of crude glycerin (0, 1, 5, 10 and 15% inclusion in the natural matter) during e...
Crude glycerin, the main by-product of biodiesel production, can replace dietary energy sources, such as corn. The objective of this study was to evaluate the inclusion of up to 30% of crude glycerin in dry matter (DM) of the total diets, and its effects on meat quality parameters of feedlot Nellore bulls. Thirty animals (227.7 ± 23.8 kg body weight; 18 months old) were housed in individual pen...
