TY - JOUR AU - Bradley, Francine AU - Ogasawara, Frank X. TI - Initial insemination interval: One approach to improving turkey fertility JF - California Agriculture JO - Calif Agr Y1 - 1983/05/01 VL - 37 IS - 5 SP - 19 EP - 19 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v037n05p19 AB - In the past 30 years, there have been decided increases in the reproductive efficiency of turkeys. Refinements in artificial insemination techniques have eliminated problems associated with natural mating, such as injury to the hen, clumsiness of the male, and preferential mating. Specially formulated diluents have made it possible to extend the semen from superior toms and reduce costs associated with maintaining large numbers of males. However, the turkey breeder hen still does not produce fertile eggs at the same level or with the same persistency as the chicken breeder hen.
