摘要
This study involved two separate experiments to determine the effects of tannic acid and lignosulfonate treatments of sunflower seed meal on the digestibility and rumen degradability characteristics of some nutrients in rams. Sunflower seed meal was treated with 3, 6 and 9% tannic acid, 5 and 10% lignosulfonate. In the first experiment, the digestibility coefficients of dry matter, organic matter and crude protein of sunflower seed meal samples were determined by a faeces collection method using 5 merino rams aged 1.5 years and weighing 66.5 kg. Tannic acid treatments of sunflower seed meal at the level of 3, 6 and 9% did not have any effect on in vivo crude nutrient digestibility. Crude protein digestibility values were not affected by the treatment of 5% lignosulfonate of sunflower seed meal but were decreased significantly (p<0,01) by the the treatment of 10% lignosulfonate. In the second experiment, four ruminally cannulated mature merino rams were used to measure the rumen degradability characteristics of dry matter, organic matter and crude protein of meal samples. The maximum potential degradability value of crude protein was increased from 88.38% to 93.47% by 6% tannic acid but was decreased by 10% lignosulfonate treatment. The rumen effective crude protein degradability values were decreased by 3, 6 and 9% tannic acid and 10% lignosulfonate treatment. Therefore, sunflower seed meal treated with tannic acid at the levels of 3, 6 and 9% and lignosulfonate at the levels of 5 and 10% was not suitable because the treatment of meal with tannic acid and lignosulfonate at these levels had no positive effect on the in vivo crude protein digestibility and rumen degradability characteristics.

独立的实验，以确定单宁酸和葵花籽粕的消化率木质素磺酸盐治疗的效果和瘤胃中公羊某些营养素降解性的特性。葵花籽粕用3,6和9％的单宁酸，5和10％的木素磺酸盐处理。在第一个实验中，干物质消化率，有机物和葵花籽粕的样品粗蛋白通过年龄1.5岁，体重66.5公斤5美利奴公羊粪便收集方法测定。的葵花籽粕在3,6和9％的水平鞣酸治疗并没有对在体内粗营养物质消化率的任何影响。粗蛋白质消化率没有影响的葵花籽粕5％木质素磺酸盐的治疗，但10％的木质素磺酸盐的治疗均显著下降（P 0.01）。在第二个实验中，4瘤胃插管成熟的美利奴公羊用来测量干物质，有机物和膳食样品的粗蛋白瘤胃降解率特性。粗蛋白的最大潜力降解值从88.38％提高到93.47％，6％的单宁酸，但被减少了10％，木质素磺酸盐处理。瘤胃有效粗蛋白降解率值分别降低了3,6和9％的单宁酸和10％的木素磺酸盐处理。因此，葵花籽粕含鞣酸在3水平处理，不适用，因为餐用在这些级别鞣酸和木素磺酸盐的处理对体内粗蛋白质消化率没有积极的效果和瘤胃降解性的特点。
