Interactions between calcium (Ca) and phosphorus (P) were studied in young chickens fed on diets high in n-alkane-grown yeast and in chicks fed on control soya-fishmeal diets for 14 d. Additions of inorganic Ca to diets containing 300 g yeast/kg caused increases in body-weight gain, gain:food ratio and bone mineralisation up to a total dietary concentration of 13.9 g Ca/kg. At all additions of Ca, bone mineralisation was inferior in yeast-fed chicks compared with control chicks. Supplementation of high Ca diets (16.8 g Ca/kg) with inorganic P led to further improvements in body-weight gain, food intake and food utilisation of chicks fed on high-yeast diets. Bone mineralisation also improved but was always inferior in the yeast-fed chicks compared with control chicks. It was concluded that Ca and P supplementation was necessary in high-yeast diets due to low dietary Ca concentrations and low availability.
对以富含正构烷烃培养的酵母的日粮喂养的幼鸡以及以对照大豆-鱼粉日粮喂养14天的雏鸡，研究了钙（Ca）和磷（P）之间的相互作用。向每千克含300克酵母的日粮中添加无机钙，可使体重增加、增重：食物比和骨矿化增加，直至日粮总钙浓度达到13.9克/千克。在所有添加钙的情况下，与对照雏鸡相比，以酵母喂养的雏鸡的骨矿化较差。用无机磷补充高钙日粮（16.8克钙/千克），可进一步改善以高酵母日粮喂养的雏鸡的体重增加、采食量和食物利用率。骨矿化也有所改善，但与对照雏鸡相比，以酵母喂养的雏鸡的骨矿化始终较差。得出的结论是，由于日粮钙浓度低且利用率低，高酵母日粮中需要补充钙和磷。
