Phosphorus requirements for 60- to 100-kg pigs selected for high lean deposition under different thermal environments.
Two experiments were conducted to determine the requirement of available P (aP) of pigs selected for high lean deposition during summer (maximum and minimum temperatures of 29.8 ± 3.6 and 21.3 ± 1.1°C, respectively; Exp. 1) and winter (maximum and minimum temperatures of 24.7 ± 2.1 and 9.1 ± 1.6°C, respectively; Exp. 2). Pigs (66.5 ± 2.8 kg, Exp. 1; and 61.1 ± 0.6 kg, Exp. 2) were randomly allo...
متن کاملBioavailability of phosphorus in meat and bone meal for swine.
Meat and bone meal (MBM), when supplemented with tryptophan, is an excellent protein source for pigs. It is also a rich source of Ca and P, but some research has suggested that the bioavailability of P is variable. Experiment 1 further examined the bioavailability of P in MBM. The MBM was obtained directly from a plant and was processed to pass through a 10-mesh screen. It contained 50.7% CP, 2...
متن کاملDietary Available Phosphorus Needs of High Lean Pigs Fed from 9 to 119 kg Body Weight
Eighteen replicates (9 barrows, 9 gilts) were used to estimate the dietary available phosphorus (AP) needs of a high lean strain of pigs during each of four stages of growth (9 to 37, 37 to 65, 65 to 92, and 92 to 119 kg body weight [BW]). Pigs were self-fed a basal diet supplemented with one of six incremental additions of AP from monodicalcium phosphate. Initially (9 to 37 kg), pigs were fed ...
متن کاملDietary calcium and phosphorus levels for growing swine from 18 to 57 kilograms body weight.
A randomized complete block design experiment was conducted using 408 crossbred pigs to evaluate the effects of six dietary Ca/P levels for growing swine (18 to 57 kg). Total dietary P levels ranged from .40 to .90% in .1% intervals with Ca concurrently increased at a 1.3:1 ratio in a 16% protein corn-soybean meal diet. Dicalcium phosphate and limestone were the source of inorganic Ca and P. Fo...
متن کاملTrue total-tract digestibility of phosphorus in monocalcium phosphate for 15-kg pigs.
The objective of this study was to determine the true total-tract digestibility (TTTD) of P in Ca(H(2)PO(4))(2) for 15-kg pigs using the regression technique. Forty-eight pigs (15.7 ± 1.53 kg initial BW) were used in a randomized complete block design. There were 8 dietary treatments with 6 replicates per treatment. The dietary treatments included a negative control (3.30 g/kg total P) and 7 ad...
