ABSTRACT This study was conducted to evaluate nutritional plans of digestible phosphorus for barrows weighing between 30 and 100 kg. Eighty animals were distributed in a randomized block design with five nutritional plans containing 2.19-1.86-1.71, 2.57-2.23-2.09, 2.94-2.61-2.46, 3.32-2.99-2.84, and 3.70-3.36-3.32 g of digestible phosphorus kg−1 of diet, respectively, for the phases of 30 to 50 kg, 50 to 70 kg, and 70 to 100 kg, with eight replications and two barrows per experimental unit. The nutritional plans of digestible phosphorus […]

The adequacy of the recommendation of phosphorus for growing Nellore steers was evaluated by means of the weight gain, feed intake and feed:gain ratio during 250 days. Fifteen steers were fed a basal P-deficient but otherwise adequate in the other nutrients, enabling gains of 500 g/day. The diet was supplemented (treatment 1 = 15 g P/day, treatment 2 = 11 g P/day) or not (treatment 3 = 5 g P/day) with monoammonium phosphate. Phosphorus deficiency did not affect organic matter […]
