BACKGROUND Sugarcane molasses is a potential by-product of the sugarcane manufacturing industry that is rich in antioxidant materials. The present study aimed to obtain antioxidative compounds from sugarcane molasses and to evaluate their ability to protect DNA from oxidative damage. RESULTS Two neolignan glucosides were isolated from sugarcane molasses using bioassay and UV spectra monitorin...

BACKGROUND AND OBJECTIVES The essential amino acid L-tryptophan can be produced by a condensation reaction between indole and L-serine, catalyzed by B. subtilis with tryptophan synthase activity. Application of the tryptophan is widespread in the biotechnology domain and is sometimes added to feed products as a food fortifier. MATERIALS AND METHODS The optimum concentration of the Iranian can...

A field experiment was carried out at the Research Center of Barkat-e-Jovein, Jovein agro-industries, Northeastern Iran, during 2008 to evaluate the effect of concentration and time of boron foliar application on root yield and quality of sugar beet (Beta vulgaris). Treatments consisted of 3 application times (30, 45 and 60 DAP) and 4 application rates (spraying with concentrations of 0, 4, 8 a...

Twelve lactating Holstein cows were utilized in a repeated switchback design to evaluate milk production and milk fat composition responses to wet corn distillers grains. Total mixed diets consisted of 31.4% corn silage, 18.4% alfalfa hay, and either 50.2% of a concentrate mix that contained mostly corn and soybean meal or 19.4% of a concentrate mix that contained mostly corn and 31.2% wet corn...

Feedlot operators may increase profitability by including distillers grains in finishing diets. However, the nutrients remaining in the by‐product are concentrated by about a factor of three during the distillation process. Manure can be applied to meet single‐ or multiple‐year crop nutrient requirements. The water quality effects of the use of distillers grains in feedlot diets and multiple‐ye...

Distillers grains is a very good protein source (>30% crude protein) which is high in ruminally undegradable protein and is very good energy source (NEL ~1.02 Mcal/lb of dry matter; [DM]) for lactating cows and growing cattle. The modest fat concentration (10 to 12% of DM) and the readily digestible fiber (39% neutral detergent fiber; NDF) contribute to the high energy in distillers grains. The...
