Volume 19, Issue 2 , August 2017, , Pages 255-264

Abstract
  In order to estimate the genetic parameters for days from calving to first service (DFS) in Iranian Holstein cattle by using repeatability, multiple-trait (MT) and random regression (RR) models, 159,482 records of parities 1 to 6 collected during 1981 to 2013 and distributed over 33 large Holstein herds ...  Read More

Volume 17, Issue 2 , October 2015, , Pages 183-197

Abstract
  Correlation between breeding value of crude milk (CM) and energy-corrected milk (ECM) was studied based on a total of 774,013 test day records belongs to 88,456 first-parity Holsteins dairy cattle calving during 1997-2009 in 165 herds (from six provinces). Genetic analysis of the traits was carried out ...  Read More
