Calcium and phosphorus requirements of growing Yankasa lambs in the savanna region of Nigeria. Estimation of the calcium and phosphorus requirement by the factorial method



Calcium and phosphorus requirements of growing Yankasa lambs in the savanna region of Nigeria. Estimation of the calcium and phosphorus requirement by the factorial method



East African Agricultural and Forestry Journal 1985; 45(4): 269-276



In a 3 x 3 factorial design 54 Y'ankasa lambs 8 to 10 months old in the savanna region of Nigeria were given diets with 0.28, 0.56 or 0.77% calcium and 0.31, 0.40 or 0.60% phosphorus. Greatest gain was for lambs given Ca 0.77 and P 0.60%. Feed efficiencies of the groups given Ca 0.56 and P 0.60% and Ca 0.77 and P 0.60% were similar and significantly greater than for all other groups. Apparent digestibility of DM improved with increasing dietary Ca and P.
