An experiment was conducted to determine 1) the length of time necessary for grower pigs to adjust to a new diet and 2) the consistency in excretion of urine and feces in 4 consecutive 5-d collection periods. The total tract excretion and digestibility values for Ca, P, and the essential microminerals were evaluated. The experiment was conducted in 6 replicates as a randomized complete block design. Pigs were fed a pretest diet from 20 to 40 kg BW that met the requirements. At 40 kg, 12 barrows…

Direct and correlated responses to selection in two lines of rabbits selected for feed efficiency under ad libitum and restricted feeding: III. Digestion and excretion of nitrogen and minerals.
TLDR
Over the whole fattening period and for ad libitum-fed rabbits, the 5% improvement in feed efficiency for the ADGrestrict and ConsoResidual lines corresponded to 400 g less feed intake and to 20 g less N intake.

Effect of dietary calcium and phosphorus levels on the total tract digestibility of innate and supplemental organic and inorganic microminerals in a corn-soybean meal based diet of grower pigs.
TLDR
Results indicate that CaP level had the greatest effect on mineral digestibility, organic microminerals had a greater digestibility than inorganic minerals, and the innate microminersals had an average apparent digestibility of 45%.
Mineral balance of finishing pigs fed copper sulfate or a copper-lysine complex at growth-stimulating levels.
TLDR
The absorption and retention of Cu was similar for pigs fed growth-stimulative levels of Cu from CuSO4 or copper lysine complex, and direct DM digestibility was similar to total collection values; however, mineral values were similar only after correction for Cr recovery.
Evaluating the NRC levels of Cu, Fe, Mn, and Zn using organic and inorganic mineral sources for grower-finisher swine.
TLDR
There is sufficient amount of innate microminerals in a typical corn-soybean meal based diet to meet the grower-finisher pig's requirement for growth and hematological measurements, and it would seem that a dietary level of 50% of the NRC requirement for Cu, Fe, Mn, and Zn would be warranted.
