[The phosphorus supply of pigs in the body weight category of 11-38 kg. 1. The effect of the phosphorus supply on the performance, nutrient digestibility, protein and fat content in soft tissue and skeleton and protein and fat deposits].
The influence of phosphorus supply on performance and nutrient composition of the empty body was studied in two individual feeding experiments with two and three groups resp. (7 or 8 animals per group). The phosphorus content of the unsupplemented diet was in the experiments I and II 2.97 and 2.41 g/kg, the supplemented phosphorus (as monocalcium phosphate) amounted of 2.5 and 2.33 g/kg diet respectively. The phosphorus supplementation increased live weight gain in both experiments by 84 and 45% and improved feed conversion by 35 and 23% respectively. Phosphorus deficiency did not influence the digestibility of nutrients. The fat content of soft tissue and skeleton of the phosphorus deficient animals was increased. They deposited 0.7 kg more fat (in both experiments) and 1.5 or 0.7 kg less protein in experiment I and II respectively. The utilisation of energy for deposition was not influenced by the different phosphorus supply.
