“…Skoglund (1940) apparently was the first researcher to investigate the dietary calcium requirement of the Ring-necked pheasant. According to Scott and Reynolds (1949), Skoglund (1940) concluded that best results are obtained with dietary levels of about 1.5 percent calcium and about 1.0 percent phosphorus. Scott et al (1958) suggested that in view of their research on the calcium, phosphorus, and vitamin D requirements of young pheasants up to five weeks of age, the minimum calcium re-quirement for normal bone ash lies between 0.93 and 1.33 percent of the diet.…”
