Embryo Transfer in Small Ruminants:

Elite females

Females selected for their superior genetics, used as egg donors in artificial reproduction.

Super-ovulation

The process of inducing females to produce more eggs than normal through hormone therapy.

Recipient animals

Females that receive harvested embryos and carry them to term.

Harvesting embryos

Collecting embryos from donor females after they have developed to a certain stage.

Biosecurity

Measures taken to ensure the health and safety of animal populations from diseases.

CIDR

Controlled Internal Drug Release device used to synchronize estrus cycles in donor and recipient females.

Artificial insemination (AI)

A reproductive technology that involves injecting sperm into the female reproductive tract using methods other than natural mating.

Estrus cycle

The recurring cycle of physiological changes in females that make them receptive to mating.

Blastocyst

An early stage of embryonic development that occurs about five to six days after fertilization.

Laparoscope

A minimally invasive surgical instrument used to view organs inside the abdomen.

Flush media

A nutrient-rich solution used during embryo collection to mimic the uterine environment.

OVU-GEN

A hormone treatment used to induce super-ovulation in female animals.

Embryo grading

The process of evaluating embryos based on their development stage and overall quality.

Surgical flush

A procedure where the uterus is exteriorized to collect embryos, requiring a surgical incision.

Non-surgical flush

A technique to collect embryos via catheterization without making an incision.

Functional CLs

Corpus luteum structures that produce progesterone and indicate a successful ovulation.

Tomcat catheter

A type of catheter used to deposit embryos into the uterus during transfer.

Holding media

Substance used for storing embryos after flushing and prior to freezing or transferring.

Fertility success rate

The percentage of successful pregnancies after embryo transfer.

Scarring

A possible complication from surgical procedures which may affect reproductive health.

Genetic material storage

The preservation of genetic resources for future breeding and improvement.

Abdominal incision

An opening made in the abdominal wall for surgical access during embryo flushing.

Embryology

The branch of biology that studies embryos and their development.

Teaser buck

A male goat used to detect females in heat without allowing mating.

Endometrial cells

Cells lining the uterus that can complicate the sorting process of embryos during flushing.

Adhesions

Bands of scar tissue that can form as a complication of surgery.

Breed out of season

The capability of breeding animals at times outside of their natural reproductive cycle.

Hormone therapy

Use of hormones to manage reproductive processes in animals.

Lutalyse

A drug used to induce the regression of the corpus luteum to terminate a pregnancy.

Fertilization

The fusion of an egg and sperm to create a zygote.

Embryo filter

A device used to separate embryos from other materials during the flushing process.

Synchronized estrus

Ensuring that donor and recipient females are in the same stage of their reproductive cycle.

Veterinary anesthetic

Medication used to induce a state of controlled unconsciousness during surgical procedures.

Nutritional status

The condition of the animals' diet and its adequacy to support reproductive health.

Male fertility assessment

Evaluation of male animals' ability to fertilize eggs, often involving semen analysis.

Ovulatory response

The reaction of the ovaries to hormonal treatment, leading to egg release.

Fertility benchmark

Standard metrics used to evaluate success in breeding programs.

Pariyt

A term referring to a female animal's reproductive history, specifically the number of offspring produced.

Embryo transfer

The process of placing an embryo into the reproductive tract of a recipient.

Cloning efficiency

The effectiveness of producing lead viable offspring clones from a single donor.

Uterine environment

The internal setting within the uterus that supports embryo development.

Genetic improvement

Enhancements in the quality of animals through selective breeding practices.

Assisted reproductive technology (ART)

Advanced techniques employed to aid reproduction, including IVF and embryo transfer.

Dystocia

Difficulties during labor or delivery often requiring veterinary intervention.

Artificial breeding program

Systematic method of breeding aimed at improving genetic traits through controlled means.

Cross-breeding

Breeding techniques that involve the mating of individuals from different breeds to produce hybrids.

Recipient management

The careful selection and upkeep of recipients used for embryo transfers.

Embryo viability

The capability of an embryo to develop into a healthy offspring.

Ovulation synchronization

Controlling the timing of ovulation in females for better success rates in breeding.

Embryonic development stages

The phases an embryo goes through from fertilization to maturity, including cleavage, morula, and blastocyst.

Threshold body condition

The minimum health and fat reserves needed for optimal reproductive performance.
