Abstract The study was conducted to identify effects of a decreased interval progesterone on the ovulatory follicle before fixed-timed artificial insemination (FTAI) by altering day gonadotropin-releasing hormone agonist (GnRH;00µg gonadorelin; Cystorelin) administration. Evaluation 7 & Synch and altered estrous synchronization protocols done using estrus expression (EE) FTAI pregnancy rate...

Se determinó el porcentaje de gestación (PG) para transferencia embriones (TETF) e inseminación artificial (IATF) a tiempo fijo, bovinos carne, Tamaulipas, bajo condiciones trópico seco. realizaron dos programas TETF en norte primero Rancho Puesta Sol, Burgos, donde se trataron 30 vaquillas con CIDR + benzoato estradiol (BE) y cipionato (ECP) al retiro del CIDR; segundo programa realizó La Indi...

INTRODUCTION There is a tendency in health policy in Ontario, Canada, to conflate 'northern' with 'rural' and to equate northern rural settings with southern ones. Although previous research has identified some differences between rural and urban practitioners, these studies have not acknowledged the subtle nuances that make rural practice different in the north than in the south. This study lo...

The objective of this study was to compare fixed-time AI pregnancy rate in Angus crossbred beef cows inseminated with frozen-thawed or fresh-extended semen. Two ejaculates from each of two Angus bulls were collected by artificial vagina and pooled for each bull. The pooled semen from each bull was divided into two aliquots; Aliquot 1 was extended using Caprogen (LIC, Hamilton, New Zealand) to a...

One hundred female Markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. This was carried out in three separate experiments. In the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); A1 (1 me...

Two experiments evaluated the effects of the first GnRH injection of the 5-d timed artificial insemination (AI) program on ovarian responses and pregnancy per AI (P/AI), and the effect of timing of the final GnRH to induce ovulation relative to AI on P/AI. In experiment 1, 605 Holstein heifers were synchronized for their second insemination and assigned randomly to receive GnRH on study d 0 (n ...

Nowadays, the commonly used table lookup scheme for IP routing is based on the so-called classless interdomain routing (CIDR). With CIDR, routers must find out the best matching prefix (BMP) for IP packets forwarding, which complicates the IP lookup. Since the IP lookup performance is a major design issue for the new generation routers, in this article we investigate the properties of the routi...
