All treatments were balanced for NPK.
The two groups were balanced for risk factors for infection.
Pens were balanced for parity, milk production, and days in milk.
Treatment groups were balanced for parity, days in milk, and mature-equivalent projected milk yield.
The two subgroups were balanced for age (mean 52 years old), gender (12 males, 2 females) and education level.
All diets were balanced for protein and minerals and supplemented with monensin (4 ppm) and sodium bicarbonate (1%).
All diets were balanced for crude protein concentration and metabolizable protein supply assuming BM and SDP were equal in rumen-degradable protein and rumen-undegradable protein.
Over six time replicates, 720 pigs (Landrace × Large White) were randomly allocated at weaning (28 ± 2 days of age), into groups of 20 which were balanced for sex.
Diets were balanced for energy and major nutrients, and contained 17.6% (w/w) fat and 13.7% protein, except for the 50% cheese diet, which had higher total cholesterol and calcium.
All diets contained 17.6 MJ/kg digestible energy, 386.2 g/kg digestible crude protein and were balanced for digestible essential amino acids to meet or exceed the requirements of rainbow trout.
Treatments were balanced for days in milk (DIM), milk yield, and parity prior to the start of the study, which was conducted between August 7th and October 7th, 2007 on a commercial dairy in Arizona (USA).
