An investigation on the possibility of using eCG for presynchronization prior to ovsynch in dairy cow
Background: Presynchronization could enhance fertility in timed breeding programs. The best presynchronization method has to justify biological requirements and to provide practical and economic advantages. OBJECTIVES: Present study investigated the effectiveness of presynchronization with equine chorionic gonadotropin (eCG) before ovsynch (eCG-ovsynch) compared to conventional presynch-ovsynch...
متن کاملHormonal control of tick development and reproduction.
Ecdysteroids (moulting hormones), juvenoids and neuropeptides in ticks are reviewed but, by far, the emphasis is on the former since this class of hormones has been the subject of most investigations. In immature stages of ticks, ecdysteroids have been shown to regulate moulting and to terminate larval diapause. Although there is a paucity of information on the molecular action of ecdysteroids ...
متن کاملNutritional controls of beef cow reproduction
The livestock industry and animal scientists have long recognized the importance of proper nutrition for cattle to achieve reproductive success. Timely resumption of estrus following parturition is a major milestone that a cow must reach for optimal reproduction. Dynamic interplay among all strata of the hypothalamo-hypophyseal-ovarian axis occurs during the cow’s transition from postpartum ane...
متن کاملProgram dependence analysis of concurrent logic programs and its applications
In this paper a formal model for program dependence analysis of concurrent logic programs is proposed with the following contributions. First, two languageindependent program representations are presented for explicitly representing control ows and/or data ows in a concurrent logic program. Then based on these representations, program dependences between literals in concurrent logic programs ar...
