Single Comb White Leghorn layers maintained in cages were fed a corn-soy diet with a simplified vitamin premix for a 12-week experimental period to determine the effect on liver lipid accumulation. Lipid content was only 29.6% of the liver dry matter and, therefore, was in the normal range and less than that seen in hens with fatty liver syndrome. Adding niacin (44 mg./kg.) or biotin (110 mug./kg.) either alone or in combination failed to significantly alter liver weight or liver lipid content. Liver lipid content of hens fed another diet with a more complex vitamin premix also was not significantly different from that of hens fed the diet with the simplified vitamin premix. None of the diets significantly affected egg production, egg weight, feed consumption or body weight changes observed over the 12-week period.
将笼养的单冠白来航蛋鸡在12周的试验期内喂食含简化维生素预混料的玉米-大豆日粮,以确定其对肝脏脂质积累的影响。脂质含量仅为肝脏干物质的29.6%,因此处于正常范围内,且低于患有脂肪肝综合征的母鸡。单独添加烟酸(44毫克/千克)或生物素(110微克/千克)或两者组合添加,均未能显著改变肝脏重量或肝脏脂质含量。喂食另一种含更复杂维生素预混料日粮的母鸡,其肝脏脂质含量与喂食含简化维生素预混料日粮的母鸡相比,也没有显著差异。在12周期间观察到,没有一种日粮对产蛋量、蛋重、采食量或体重变化有显著影响。
