Improved Pregnancy Outcomes in Beef Heifers Through Delayed Insemination of Sexed Semen. [PDF]
ABSTRACT This study evaluated the effect of the timing of Y‐sorted sexed semen (SS) insemination after the onset of estrus on reproductive outcomes in beef heifers and examined the influence of AI sires and their sperm DNA fragmentation (%SDF) over time.

Effect of intravaginal device type and treatment length on estrus synchronization and reproductive performance of Farahani ewes out of breeding season [PDF]
This study was conducted to evaluate reproductive performance of Farahani ewes subjected to four estrus synchronization programs. Twenty four ewes were synchronized with flurogestone acetate sponges (FGA) or controlled internal drug release (CIDR ...

Cidre: programming with distributed shared arrays [PDF]
A programming model that is widely approved today for large applications is parallel programming with shared variables. We propose an implementation of shared arrays on distributed memory architectures: it provides the user with an uniform addressing scheme while being effcient thanks to a logical paging technique and optimized communication mechanisms.

Presynchronizing PGF2α and GnRH injections before timed artificial insemination CO-Synch + CIDR program [PDF]
Fixed-time artificial insemination is an effective management tool that reduces the labor associated with more conventional artificial insemination programs requiring detection of estrus.

Estrous synchronization in sheep with reused progesterone devices and eCG
The objective of the present research was to determine the effect of long synchronization protocols based on reused progesterone devices (controlled internal drug release [CIDR]) associated with different doses of equine chorionic gonadotropin (eCG) on ...

Endogenous and exogenous progesterone influence body temperature in dairy cows [PDF]
Three experiments were conducted to determine the effect of endogenous progesterone (P4) on body temperature comparing lactating, pregnant with lactating, nonpregnant cows, and to study the effect of exogenous P4 administered via a controlled internal ...
