Two experiments were conducted to evaluate the effects of a winter feeding strategy on the performance, lactation, reproduction, and feed costs of springcalving, lactating beef cows. In Exp. 1, Angus (n = 66) and Simmental (n = 70) cows were allotted to 1 of 4 treatments: 1) distillers dried grains with solubles (DDGS) and free-choice corn residue bales; 2) corn bran and DDGS and freechoice cor...

Sugar recognition specificities of class III (OsChib1a) and class I (OsChia1cDeltaChBD) chitinases from rice, Oryza sativa L., were investigated by analyzing (1)H- and (13)C-nuclear magnetic resonance spectra of the enzymatic products from partially N-acetylated chitosans. The reducing end residue of the enzymatic products obtained by the class III enzyme was found to be exclusively acetylated,...

this study was conducted to investigate the effect of organic and bio-fertilizers on trifluralin durability.herbicide persistence is an important consideration in crop production since residue levels of trifluralin herbicides can persist to the next growing season and may injure sensitive crops in the rotation. residues of trifluralin persist in the soil for long periods. extremely small amount...

Background and Objectives: With regard to the hazards of nitrite, application of natural preservatives in order to reduce the microbial load of meat and meat products is increasing. Owing to their anti-bacterial properties, red barberry and the dried residue of red grape could be suitable replacers for nitrite. Materials and Methods: Agar dilution method was employed in order to determine th...

an experiment was conducted to evaluate the effects of some technological processes on the residual levels of imidacloprid in strawberry fruits and products. according to their half-life (t1/2) values, strawberry fruits can be safely harvested for human consumption 7.4 days after spraying. the removal ratio of imidacloprid residue in strawberries was in the range of 9.9–30.55% by washing with t...
