ABSTRACT An experiment was conducted to determine the required levels of supplementary vitamin D and calcium in meat-type quail (Coturnix coturnix sp) between 15 and 35 days old. The experiment was a 4 × 4 factorial design with four levels of calcium: 0.42, 0.58, 0.74, and 0.90% and four levels of vitamin D: 1,000; 2,000; 3,000; and 4,000 IU. Body weight and body weight gain increased linearly and feed conversion showed some linear improvement due to increased levels of Ca and vitamin D. The increased vitamin D levels resulted in a linear increase in feed intake. Calcium and vitamin D requirements in meat-type quail between 15 and 35 days of age is greater or equal to 0.90% Ca and greater or equal to 4,000 IU of vitamin D, probably because the experiment was conducted during the pre-laying phase.
