Loss of Follicles during the Follicular Phase of the Estrous Cycle of Swine as Affected by Genetic Group and Level of Feed Intake

SUMMARY One hundred and .tWO puberal gilts from nine genetic groups were used to determine the association of two morphological types of Ovarian follicular loss (hemorrhagic and milky) with genetic background of ~gilts, level of feed intake and stage of estrous cycle. At estrus (day 0 of estrous cycle) a lesser prqportion of gilts (P
