The interaction between malabsorption syndrome (MAS) and dietary vitamins A and D was studied in broiler chicks reared in floor pens for 4 weeks. The chicks were naturally infected with MAS, whereas hatchmates fed the same diets but in a separate facility (battery brooder) did not exhibit signs of MAS and, therefore, were considered controls. MAS significantly reduced body weights, bone ash, serum calcium and phosphorus concentrations, and liver lipids and increased the incidence of skeletal abnormalities (tibial dyschondroplasia and rickets). Rather than ameliorating the effects of MAS, vitamin A caused a further reduction in body weight and bone ash. A possible nutrient interaction between vitamin A and vitamin D or vitamin E in birds with MAS may account for the exacerbative effect of vitamin A.
在地面围栏中饲养4周的肉鸡雏鸡中，研究了吸收不良综合征（MAS）与膳食维生素A和D之间的相互作用。雏鸡自然感染了MAS，而在单独设施（层叠式育雏器）中饲喂相同日粮的同批雏鸡未表现出MAS症状，因此被视为对照。MAS显著降低了体重、骨灰分、血清钙和磷浓度以及肝脏脂质，并增加了骨骼异常（胫骨软骨发育不良和佝偻病）的发生率。维生素A非但没有改善MAS的影响，反而导致体重和骨灰分进一步降低。MAS雏鸡中维生素A与维生素D或维生素E之间可能存在的营养相互作用，可能是维生素A产生加剧作用的原因。
