Abstract
Dietary Ca/P ratios of 1:1, 4:1, and 8:1 were studied in 30 Holstein steers in a 168-day split plot in time and space experiment. A factorial arrangement among feed intakes and Ca/P ratios existed at each time period. Animals receiving the 8:1 Ca/P ratio diets gained less daily than the 1:1 and 4:1 groups. Animals fed the 1:1 Ca/P ratio diets had higher serum inorganic phosphorus, lower serum calcium, and a narrower serum Ca/P ratio than those fed the 4:1 and 8:1 diets. There were no adverse effects on average daily gain and feed efficiency from feeding the 4:1 Ca/P ratio diet.
