The preventive measures were: chain, rubber hose, straw rack (5 g/pig/day) and the provision of straw on the floor twice daily by hand (2 10 g/pig/day). The two curative treatments, which were applied following the onset of tail biting in a pen were: straw twice daily (as in the fourth p...
Fertilizer N applied at ever-increasing rates sometimes accumulates in the soil. The practice of fertilizing grain straw with N to stimulate decomposition is questionable, but decomposition of straw immobilizes N that must be compensated for in fertilizing the succeeding crop. Too much N decreases the sucrose content of sugarbeets and decreases sucrose recovery. Experiments were conducted to de...
هدف این تحقیق بررسی تأثیرات انجماد شیشه ای کمپلکس های تخمک–کومولوس (توده های coc) گوسفند بر بقای توده ها، بلوغ تخمک ها، بیان ژنهای بلوغ و آپوپتوزی، شیوع ناهنجاریهای کروموزومی و تغییرات فراساختاری توده ها بود. توده های coc جدا شده دارای کیفیت خوب به چهار گروه، غیرانجمادی کنترل، انجمادی conventional straw ، cryotop و solid surface تقسیم شدند. در گروههای انجمادی conventional straw وcryotop، توده...
Molecular-bred Coprinus cinereus monokaryotic strains with high lignin- and xylan-degrading activities were mixed-cultured at 27 degrees C in the liquid medium containing 0.5% (w/v) cut rice straw and 0.025% MnCl2. After 3 weeks, the culture supernatant was extensively treated with crude cellulase, showing the presence in it of 9.3% of the total cellulose of rice straw. When rice straw treated ...
