Available phosphorus in diets for 15 to 30 kg pigs genetically selected for meat deposition
With the objective to evaluate the effect of dietary available phosphorus levels (aP) on the performance, blood and bone parameters of castrated male and female pigs, genetically selected for meat deposition, 60 commercial hybrids pigs with initial weight of 15.54±0.68 kg were allotted in a complete...

| description | With the objective to evaluate the effect of dietary available phosphorus levels (aP) on the performance, blood and bone parameters of castrated male and female pigs, genetically selected for meat deposition, 60 commercial hybrids pigs with initial weight of 15.54±0.68 kg were allotted in a completely randomized block design, with six treatments (0.103, 0.210, 0.317, 0.424, 0.531, and 0.638% aP), five replicates, and two animals per experimental unit. Pigs were fed ad libitum and water was provided until the end of the experimental period (21 days), when animals reached 31.31±2.94 kg. Daily weight gain and daily feed intake increased, while the feed conversion improved quadratically up to 0.534, 0.487, and 0.574% aP maximum responses, respectively. The aP intake and the values of inorganic phosphorus in serum increased linearly with increasing the levels of aP in the diets. Alkaline phosphatase activity increased quadratically up to 0.558% maximum response. Bone breaking strength and calcium, phosphorus, and ash contents in the bones increased linearly with increasing aP concentration in the diets. The available phosphorus requirement of castrated male and female pigs genetically selected for meat deposition from 15 to 30 kg for best results of performance is 0.574%, corresponding to a daily intake of 8.26 g of available phosphorus. |
