[The phosphorus supply of swine between 11 and 38 kg. live weight. 2. The phosphorus, calcium and ash deposit in skeletal and soft tissue homogenates during P deprivation and during the use of two different phosphate feedings and different ration conditions].
The influence of phosphorus (P) supply on the content of ash, P and Ca of the skeleton and soft tissue as well on the P deposition in the empty body of pigs (approximately 35 kg live weight) was studied in 3 individual feeding experiments with different diets (P-content 2.97, 2.41 or 3.7 g/kg diet). In each experiment 2 of the 3 groups (7 or 8 animals per group, initial weight approximately 11 kg) were supplemented with the feed grade phosphates "Rükana" or "Cefkaphos". In the experiments the supplemented amount of P as "Rükana" or "Cefkaphos" was 2.50, 2.33 or 0.5 g/kg of the diet. After intake of approximately 65 kg of the diet the animals were slaughtered. Homogenates of bones and soft tissues of the left half of the empty body were analysed for ash, P and Ca. Both of the feed grade phosphates increased these parameters in the skeleton and soft tissues as well the P deposition in the body to the same level. In the middle of the experiments the P deposition per kg live weight gain amounted to 4.6 g ("Rükana") and 4.4 g ("Cefkaphos").
