Experiments were conducted to determine the effect of supplementary dietary silicon on weight gain, feed efficiency, percent tibia bone ash and on the development of tibial dyschondroplasia in broiler chickens. Experiments 1 and 2 were conducted with casein/gelatin-based purified diets and Experiments 3 and 4 with corn/soy-based practical diets. All experiments used day-old broiler cockerels and lasted 16 d. Silicon supplementation (250 mg/kg) significantly decreased growth rate and the incidence and severity of tibial dyschondroplasia in Experiment 1 and had no effect on either parameter in Experiments 2-4. Dietary silicon supplementation significantly reduced feed efficiency in Experiments 1 and 3. Tibia bone ash was unaffected by dietary silicon supplementation in any of the experiments conducted. The results of the present studies indicate that dietary silicon supplementation has no effect on growth and skeletal development in broiler chickens.
进行了多项实验，以确定补充膳食硅对肉鸡体重增加、饲料效率、胫骨骨灰百分比以及胫骨软骨发育不良的影响。实验1和2使用基于酪蛋白/明胶的纯化日粮，实验3和4使用基于玉米/大豆的实用日粮。所有实验均使用一日龄的肉用公鸡，持续16天。在实验1中，补充硅（250毫克/千克）显著降低了生长速度以及胫骨软骨发育不良的发生率和严重程度，而在实验2 - 4中对任何一个参数均无影响。在实验1和3中，补充膳食硅显著降低了饲料效率。在进行的任何实验中，膳食硅补充剂均未影响胫骨骨灰。本研究结果表明，补充膳食硅对肉鸡的生长和骨骼发育没有影响。
