AB - Eight hundred and fifty two multiparous Holstein cows in mid-lactation were used in a completely randomized and nested design with two treatments and three replications. Treatments were: 1) Isfahan and 2) Borkhar-Meymeh. Replications were: 1) class of one to five cows 2) class of six to ten cows and 3) class of eleven to twenty cows. Paired t-test was used for the comparison of nutrient consumption and requirement. The obtained results of one-year-old experiment indicated that township and different classes had no effect on consumption of dry matter intake (DMI), net energy lactating (NEL), metabolizable protein (MP), calcium (Ca), phosphorus (P), potassium (K), magnesium (Mg), sodium (Na), chlorine (Cl), sulphur (S), selenium (Se), zinc (Zn), copper (Cu), iodine (I), vitamin A, vitamin D, vitamin E, rumen degradable protein (RDP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and non-fiber carbohydrate (NFC). Township had a significant effect on consumption of rumen undegradable protein (RUP) (P LA eng UL http://jcpp.iut.ac.ir/article-1-858-en.html M3 ER -
