Characterization of apoptosis in the developing bovine fetal ovary: association with germ cell loss
(University of Missouri--Columbia, 2008)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] During early bovine fetal development a 170 fold increase in germ cells occurs from d 50 to 110 followed by a rapid decline of germ cells by d 170. To ... -
Comparison of controlled internal drug release (CIDR)-based protocols to synchronize estrus and facilitate artificial insemination (AI) in postpartum beef cows
(University of Missouri--Columbia, 2008)Artificial insemination (AI) and estrous synchronization are reproductive technologies that enable beef producers to efficiently improve herd genetics. The recent development of protocols designed to synchronize estrus and ... -
Comparison of thermoregulatory mechanisms in heat sensitive and tolerant breeds of Bos taurus cattle
(University of Missouri--Columbia, 2008)Two Bos taurus breeds with known differences in heat tolerance were tested under controlled conditions to evaluate heat tolerance. Romosinuano (RO) is a tropically adapted breed. Nine Angus (304 [plus or minus] 7 Kg BW; ... -
Digestible lysine and threonine requirements of male turkeys and their effects on performance of male turkeys fed practical diets to market age
(University of Missouri--Columbia, 2008)Seven experiments were conducted to determine the minimum requirements of digestible lysine (dLys) and digestible threonine (dThr) from 1 to 21 weeks of age for male turkeys. Requirement values were similar to NRC (1994) ... -
