Abstract:
The aims of this study were to compare the embryo recovery rate in Angora goats based on application timing; at the beginning (September – October; Group 1) and end (December; Group 2) of the breeding season and to evaluate the viability and survivability of fresh or vitrified-thawed embryos when transferred. For this purpose, nine Angora goats were used as donors and thirthy Angora goats were used as recipients. Donor goats were synchronized and superovulated with traditional protocol and were mated with fertile bucks. At the 156th hour of the mating, embryos were collected surgically and eva

BackgroundReproductive efficiency after hydrometra (HD) treatment is usually unsatisfactory.MethodsTo identify mechanisms involved in low reproductive efficiency of HD-treated goats, pluriparous dairy goats treated for HD (n=10, HD) or with no reproductive disorders (n=11, control: CONT) were induced to oestrus and superovulated. Goats were mated with fertile bucks and seven days after oestrus, non-surgical embryo recovery was performed.

In this study, laparoscopic embryo transfer (ET) was conducted to overcome the disadvantages of laparotomic ET including invasiveness, adhesions and duration of surgery in Korean black goats (Capra hircus aegagrus). Transferred transgenic embryos were produced by DNA pronuclear microinjection of in vivo derived zygotes. Recipient goats were synchronized in estrus by using an intravaginal progesterone device CIDR® for 13 days and injection of 400IU PMSG 48hrs before CIDR® removal. Embryos were transferred on day 4 after CIDR® removal. Recipient goats were starved for 48hrs and suspended head do

Abstract:
Chlamydia abortus is a gram-negative obligate intracellular bacterium. Its lifecycle includes a resistant infectious form and a metabolically active non-infectious form. Chlamydia abortus infection results in abortion in goats; in nonpregnant animals the infection is usually subclinical. Chlamydia abortus presents a major zoonotic risk for pregnant women. The aim of this study was to investigate whether the embryonic zona pellucida (ZP) protects early embryo cells from infection and to test the efficacy of the washing protocol recommended by the IETS for bovine embryos.

Abstract:
Goats are important livestock species because they produce meat, milk, and fibre and are also easily maintainable on small farms. Although goats provide many products and consumption of goat meat is increasing in the United States, the industry lags compared with many species with regard to IVF techniques to enhance goat production. It has been demonstrated in other species that male IVF embryos tend to develop faster than those of females. This may be due to increased tolerance of male embryos to inadequate conditions, particularly, glucose concentrations in culture media. However, the sex ra

Coxiella burnetii, an obligate intracellular bacterium of worldwide distribution, is responsible for Q fever. Detection of significant bacterial loads in flushing media and tissue samples (oviducts and uterine horns) from the genital tracts of nonpregnant goats is a risk factor for in utero infection and transmission during embryo transfer (Alsaleh et al. 2011 CIMID 34, 355–360).

Abstract:
The advent of in vitro fertilization (IVF) marked a watershed in the scientific understanding of the human embryo. This, in turn, led to a renaissance of human embryology, accompanied by the ability to manipulate the human embryo in the laboratory. This ability has resulted in yet further developments: refinements of IVF itself, preimplantation genetic diagnosis, the derivation and extraction of embryonic stem cells, and even various forms of cloning. There are immense social and scientific pressures to utilize the artificial reproductive technologies in ways that have little or no connection with overcoming infertility. As the original clinical goals of IVF have undergone transformation ethical concerns have escalated, so much so that they are condemned by some as illustrations of ‘playing God’, while any babies born via some of these procedures are labelled as ‘designer babies’. Both terms reflect the fear and repugnance felt by some at the interference with the earliest stages of human life by the artificial reproductive technologies. It is at these points that bioethical analyses have an important contribution to make.

This case study at Embry-Riddle Aeronautical University – Daytona Beach (ERAU-DB) describes the process of facilitating a faculty peer observation model that uses asynchronous electronic feedback through the Teaching Partners program offered by the Center for Teaching and Learning Excellence (CTLE). This practical, hybrid model of peer observation builds on practices found in current models and uses digital recording and web-based software to encourage faculty feedback that will positively impact their pedagogical practice. The results of this study suggest to truly cultivate a dialogue between faculty and/or education developer in the process, the goals should be clearly stated, the reflection should be clearly defined using the current research when possible, and the process should be modeled in practice. This comparative analysis also suggests that the hybrid model of evaluation, coupled with the implementation of video asynchronous electronic commenting system, resulted in increased faculty reflection that impacted classroom instruction.
