ET - Embryo Transper -Terraweena Stud



Transfer of embryos
With the exception of the freeze-thaw cycle indicated above, the transfer of fresh or frozen embryos is essentially the same. Most embryo transfers are performed using the laparoscope, in a fashion similar to that used for AI. As transfers can be made quite quickly, local anesthesia and sedation are often sufficient. Once the animal is placed on the tilt table, the abdomen is prepared routinely and infiltrated with local anesthetic. The laparoscope is placed through the abdominal wall and the ovaries inspected for evidence of one or more CL's. A CL (corpus luteum) is a progesterone producing body on the ovary where an ovulation occurred. Usually in sheep and goat recipients more than one CL is observed. If a normal CL is identified, a small incision is made on the midline of the abdomen, forward of the udder. The tip of the uterine horn corresponding to the ovary bearing the CL is pulled out. A fine catheter is used to transfer the embryos into the uterine horn. The uterine horn is allowed to return to the abdomen and the small incisions are closed. In most cases, two embryos are transferred into each suitable recipient although this may range from one to three. Pregnancy rates are usually higher with fresh embryos than frozen embryos of a similar developmental stage. The steps involved in freezing can result in the destruction of some cells of the embryo and may reduce the ability of the embryo to develop normally.

An injection of long acting penicillin or tetracycline is given and depending upon the operator, anti-inflammatory products may be recommended. In the majority of cases, post-operative recovery is rapid. Donors and recipients should be monitored for at least a week for signs of illness and treatment begun immediately if deemed appropriate.

Embryo collection

The video clip I took along my visiting at Tarraweena Stud





Embryo collection
Embryos are usually collected from the donor 6-7 days after breeding. At that time embryos and any unfertilised ova are freely suspended in the small amount of fluid found in the horns of the uterus. Embryo collection in the small ruminant species is a surgical procedure although non-surgical techniques have been the subject of considerable research. The cervix of sheep and goats is very difficult to penetrate, especially 6-7 days after heat, and commercial success in non-surgical embryo collection is limited to goats.

Sedation and local anesthesia of the donor may provide adequate restraint but we prefer general anesthesia as it allows optimal control over the procedure. Once the donor is anesthetised she is placed on her back in a small tilt table and the underside of her abdomen is prepared for surgery. A laparoscope (a rigid fibre-optic device) is inserted through a small incision in the skin to allow evaluation of the response to super-ovulation. If there is evidence of a satisfactory response (several CL's should be obvious on each ovary) the uterus is identified and elevated through a small incision (7-10 cm.) on the midline. A soft rubber Foley catheter is introduced to the uterine horn and the cuff of the catheter inflated to seal off the uterus. A sterile solution is flushed through another small catheter placed at the tip of the uterine horn to carry the embryos out of the uterus, through the Foley catheter and into a small collection dish or filter. After one horn is flushed, the procedure is repeated with the other uterine horn. Following the flushing procedure, the incisions are closed, and the ewe is given prostaglandin to help her uterus evacuate any debris.

We take particular care to minimise the formation of adhesions (scar tissue) that can be stimulated during almost any abdominal surgery and can reduce fertility. While donors may be flushed 2-3 times in a season, allowing them to become pregnant after a few flushes lets the reproductive tract become stretched, and breaks down some of those adhesions.

The recovered flush fluid is examined under a microscope. Unfertilised eggs, degenerating embryos and good quality embryos may all be found in varying proportions. A quality grade (1 being excellent and 4 being very poor) and developmental stage is assigned to each of the recovered embryos. In most cases, excellent quality embryos result in the highest pregnancy rates. Only grade 1 embryos are eligible for export. Lower grade embryos (grades 2 and 3) may be transferred fresh and they can result in pregnancies. Depending upon the aims of the project, the embryos may be transferred into recipient ewes or frozen for use at a later time. The embryo has several biological features which spare it from infection by many serious viral and bacterial agents. Embryo transfer is an effective means by which a donor with a chronic illness - a ewe with OPP or a doe with CAE - may reproduce with no risk of disease transmission to her offspring. The washing of embryos in several changes of holding medium, and possible treatment with a protein dissolving enzyme (trypsin) for export purposes, means that there is virtually no risk of disease transmission to embryo recipients or to the developing fetus (assuming the recipients are free of the disease in question).

Recipient selection and care
A major determinant of the success of an ET program is the quality of the recipients. The pool of potential recipient animals should be in excellent health. All recipients should be sound. Well grown doelings or ewe lambs may be used but females with a history of good mothering are preferred. Animals with a history of mastitis, reproductive disorders or dystocia (difficulty giving birth) should be avoided. Recipients should be identified 4-8 weeks prior to sponging and penned by themselves. Each animal should be uniquely identified, preferably with an ear tag that can be read at a distance. Potential recipients should be treated with parasiticides appropriate to the geographic location and season. Vaccinations against Clostridial diseases and any screening blood tests for production limiting-diseases (CAE, OPP, Johne's disease etc) should be completed in advance of the program. The use of cull animals as recipients for an ET program will dramatically compromise the outcome. Even if these animals do become pregnant, entrusting them with the care of valuable offspring is ill-advised.

Donors and recipients
Lean but healthy recipients are desirable. Donors and recipients should be started on a plane of nutrition to allow a slight increase in body condition beginning two weeks prior to insertion of intra-vaginal devices. Salt and access to minerals should be provided. Where donors and recipients are fed stored forages, vitamin A and D supplementation is required. A plentiful supply of good quality hay with a moderate protein level (14-16%) is generally adequate and exclusively legume (alfalfa, clover) diets should be avoided. It is very important that the feeding levels of recipients should not be decreased, or dramatically altered, following ET as this may contribute to early embryonic or fetal loss. In all cases, every effort should be made to be minimise stress, including rough handling, sudden dietary switches and commingling with strange animals. Handling with dogs should be avoided. Donor and recipient cycle synchrony Ideally, the donor and the recipients should be in heat (estrus) and ovulate within 12 hours of each other to help ensure that at the time of ET the uterine environment of the recipient is very similar to that of the donor. While donor and recipients heats should be synchronised as closely as possible, asynchrony of plus or minus 24 hours still results in acceptable pregnancy rates. Synchronising the time of estrus in the recipients and donors usually involves the use of intra-vaginal sponges or other sustained release forms of progesterone. Prostaglandin (cloprostenol - Estrumate® or dinoprost -Lutalyse®) and PMSG (pregnant mare serum gonadotrophin also known as eCG equine chorionic gonadotrophin) and GnRH can also be incorporated to narrow the time interval during which ovulation occurs. Wherever possible, recipient females should be placed with teaser animals to enhance ovulations. Under no circumstances should recipients be allowed access to intact males as they will be bred and probably become pregnant. Pregnant recipients compromise the outcome of many programs. Despite hormonal manipulation of their reproductive cycle, some potential recipients do not synchronise or are found otherwise to be unfit as embryo recipients at the time of ET. To ensure adequate recipients are available, approximately 6 ewes or 10 does should be synchronised per donor. For frozen embryo programs an average of two embryos per recipient should be projected and 30% more recipients than will minimally fit the program should be synchronised. Where recipient availability is limited, up to three embryos of the same mating may be transferred into a recipient (assuming she is a relatively large animal). Where recipient numbers are very limited, surplus embryos may be frozen for transfer at a later place or time. Prior to embarking on an embryo transfer program, we consult with our clients to provide a schedule to optimise the synchronisation of their recipients and donors. All schedules, including recommended brand names, dosages, routes of administration, and timing of procedures are provided. Adherence to all details provided in the schedule is of considerable importance to the outcome of the program.

Embryo freezing
The purpose of freezing embryos is to hold the embryo in a state of suspended animation so that when the embryo is thawed for transfer at a later date or place, normal biochemical processes in the embryo may be resumed and the embryo can then go on to develop normally. Embryos of good to excellent quality can be frozen and thawed with a slight reduction (10-20%) in the pregnancy rate normally expected with fresh embryos. Sheep and goat embryos are generally frozen in 0.25 mL plastic straws, each straw containing 2-4 embryos of a similar developmental stage from the same flush.

Prior to freezing, the embryos are moved from their holding medium and placed in a cryo-protectant solution. This solution acts as an anti-freeze by replacing some of the water that is present in the cells of the embryo. This helps ensure that during the freezing process ice crystals do not form in the embryo's cells causing them to rupture and the viability of the embryo to be reduced. The embryos suspended in the cryo-protectant are then loaded into straws, the straws are sealed and labelled by convention as to their contents. The straws are then placed in an embryo freezer and then cooled at a controlled rate to between -30 and -35 C. At that point the embryos can then be plunged into liquid nitrogen (-196 C) for indefinite storage.

Most international movement of livestock genetics now occurs in the form of frozen or cryo-preserved embryos.

Thawing embryos
Frozen embryos must be handled to ensure that they stay frozen - improper handling and partial thawing and re-freezing is a potential cause of poor pregnancy rates with frozen embryos. They must remain immersed in liquid nitrogen in a storage tank, or transported in a special 'dry shipper', which holds the embryos in liquid nitrogen vapour.

Frozen embryos are thawed in a manner quite similar to frozen semen, and should be handled under carefully controlled conditions of time and temperature. Following a brief exposure to air, the straw containing the embryo(s) is immersed in warm water, the straw dried and the contents of the straw evacuated into a small sterile dish. The embryos are transferred from the freezing solution into a modified embryo holding solution. Depending upon the specific cryoprotectant used, step-wise removal of the cryoprotectant may be necessary prior to transferring the embryos into a recipient animal. This is an opportune time to re-evaluate the state of the embryo(s) prior to transfer into the recipients and to comment on the impact that freezing may have had upon them. The International Embryo Transfer Association has standardised codes which describe embryo grade (quality) and developmental stage (age) of the embryo and those should be indicated on the certificate of embryo transfer, along with embryo donor, sire and recipients identification.

Transfer of embryos
With the exception of the freeze-thaw cycle indicated above, the transfer of fresh or frozen embryos is essentially the same. Most embryo transfers are performed using the laparoscope, in a fashion similar to that used for AI. As transfers can be made quite quickly, local anesthesia and sedation are often sufficient. Once the animal is placed on the tilt table, the abdomen is prepared routinely and infiltrated with local anesthetic.

In the majority of cases, post-operative recovery is rapid. Donors and recipients should be monitored for at least a week for signs of illness and treatment begun immediately if deemed appropriate.

Facilities
The majority of our small ruminant ET procedures are conducted on the farm. Efforts should be taken at all times to reduce stress to the recipient animals so maintaining them in their original groups on their own farm is preferable. While an absolutely sterile operating environment is impractical, a clean, dust free area is highly desirable to optimise the outcome for both surgery and embryo handling. Enclosed, well lit facilities with a solid well drained floor, preferably concrete, are desirable. Access to warm water and several power outlets (110/120v) will be required. Embryos are susceptible to injury and death under conditions of fluctuating temperature. It is very important that the area used for handling embryos and performing ET is draft free and can be maintained at a fairly stable 21 C. There should be no areas of very warm or cold air.

Ideally, the doors into and out of the ET area should not communicate directly to the outside as this often contributes to widely and wildly fluctuating temperatures and drafts. Animal movement through the ET area should flow in a single direction. Most importantly, animals about to undergo surgery should be kept on a dry, feed-free area. Their movement should be restricted so they may be caught and restrained with minimal anxiety. Animals should be allowed to recover in a warm, dry, deeply bedded area where they may be observed and allowed access to feed (hay) and water once they are standing. At least three assistants capable of handling and lifting sheep will be required. The ET team will be occupied with anesthesia, preparing animals for surgery, performing surgery, handling embryos and post-operative care. We cannot allow our ET team to be distracted from those responsibilities.

Expectations and caveats
Average Range
Efficiency of embryo collection 12 CLs 0-30
Transferable embryos 6 embryos 0-30
Embryos surviving to birth 70% 0-100%
Recipients pregnant 60% 0-100%



Approximately 25% of potential donors do not respond to super-ovulatory treatments. Pregnancy rates are generally, but not always, lower with frozen than with fresh transferred embryos.

Embryo collection and transfer in small ruminants involves general anethesia and surgical procedures. Although modern anesthetics and surgical techniques reduce risk to donor and recipient animals, it should be appreciated by owners that serious and potentially fatal complications, while rare, may occur. Regurgitation of stomach (rumen) contents under anesthesia is potentially fatal. To reduce the risk of aspiration occurring during anesthesia, we first induce anesthesia with an injection and then insert a cuffed, semi-rigid, rubber tube through the mouth and into the trachea (wind-pipe) of the animal This endo-tracheal tube is connected to an anesthetic machine which delivers oxygen and anesthetic gas at safe, controllable levels. Even with these precautions, it is critical that the donor and recipient animals not have access to any water or feed for at least 24 hours prior to the time of embryo transfer.

We make every effort to ensure that anesthesia and surgeries are performed safely but every client embarking on an ET project should be apprised of potential risks.

Pregnancy rates are variable and relate to donor, recipient, embryo and operator factors, many of which may interact, usually negatively, to influence the outcome. Clients thinking of an ET program should be prepared to follow directions explicitly. There are no guarantees and careful attention to detail is important to reduce the chances of a program being disappointing and increase the probability of it being remarkably rewarding.

My Visit to the Terraweena - AI and Embryo

My visiting to Terraweena Boer Goat Stud.
Terraweena owned by Australian Breeding Service Pty. Ltd (ABS) ia a leading breeder and supplier of Boer goats, Dorper and White Doper.

ABS was responsible for the introduction of the Boer goats to Australia in 1990. Since that time they have exported live animals to many country of the world as well as specializing in the transfer of livestock through the means of embryo transfer.

Having bred Boer goats since 1989, the Terraweena stud has established a style of its own. The original bloodline are now completely infused and are recognized simply as the Terraween Type. Nevertheless, frequent trips to south Africa are made to ensure that Terraweena remains at the cutting edge. ABS latest importation of embryo from South Africa was from Lukas Burger stud in 2006 and resulted in the prized”Terrweena Burger” an animal in a class of his own and Australian National Champion Buck in 2007.







At Terraweena Angus Burneet Smith explain to me how they made AI
and the embryo transfer...he also offer me to introduced the embryo in Malaysia
Artificial Insemination is the injection of semen from a goat buck into the vagina of doe goat by chosen tool …….
History of artificial Insemination
Artificial Insemination is older than everyone in this room’s ages combined. Documents from around 1322 A.D. state that an Arab chief wanted to mate his mare to a stallion owned by his rival. So he preformed an amateur version of the artificial insemination we know today. Then in 1780, Spallanzani successfully bred two dogs with the use of A.I. Leading to him being named the inventor of artificial insemination.
Advantages of artificial insemination
The greatest advantage of Artificial Insemination is that it increases the maximum use of superior sires. It allows easier access for consumers to obtaining high quality sperm
Increase accuracy and selection intensity
You can compare herds easier.
Introduce new genetics easier

The collection of semen
There are several ways to collect semen. Although the use of an artificial vagina is most common.The artificial vagina is made of a firm cylindrical tube that has a thin-walled rubber lining.
Semen Extension
The main reason for extending (or diluting) the semen is to increase the number of females that can be inseminated from one ejaculation. A normal ejaculated from a dairy bull will contain 5 to 10 billion sperm, which can be used to inseminate 300 to 1000 cows if fully extended. There are several good semen extenders. Those made from egg yolk or pasteurized, homogenized milk are two of the most widely used. A good tender not only adds volume ejaculate but favors sperm survival and longevity. Dilution rate depends on quality of sperm per insemination have good conception rates. Penicillin and streptomycin are added to semen extenders. These antibiotics inhibit bacterial growth and reduce danger of spreading diseases such as vibriosis.




Handling Semen
A revolutionized discovery was made; That semen could be frozen. It can also be stored for indefinite periods. British scientists discovered that addition of glycerol to the semen extender improved resistance of sperm to freezing, in 1949. Glycerol removes water from the sperm before freezing. It also prevents the ice crystals from damaging the sperm.

Semen storage
One way is dry ice and alcohol (-100 degrees F)
Liquid nitrogen (-320 degrees F), the preferred method. Is preferred because there isn’t any deterioration with age.
When using dry ice and alcohol fertility declines gradually.

But …before your artificially inseminate
The first step in figuring out the right time to consider artificial insemination is detecting the time that your female is in heat. Many prefer to use prostaglandin (s) or “PG” (potent hormone-like substance found in bodily tissues that have important functions in the animal body,) so they can focus their labor to restricted amounts of time for heat detection, instead of relying on daily observations.
There are a multitude of ovulation management products being used today, which include combinations of either PG and/or GnRH (other hormones). While PG is used, as a one-shot or two-shot administration it has been the basis of most operations, the development of the OvSynch procedure has become more popular, and good results have been achieved with this GnRH/PG combination.

Australia - World Leaders in Livestock Export

Australia is recognized as the world leaders in the export of livestock. This is due to a national inquiry initiated in 2003 (the Keniry Report) which made the following eight recommendations, all of which were implemented by the end of 2004:
Veterinarians to be on ships for all long haul voyages (for example, to the Middle East).
The development of new national animal welfare regulations, requirements and standards.
Increased government involvement in regulatory control (including unannounced audits and inspections).
The introduction of an individual consignment risk management approach for all shipments which will ensure that all potential risks affecting animal care are minimised.
Upgrade of assembly depots.
Progress on the establishment of formal agreements with the importing country.
Governments in the Middle Eastern/North Africa region to supervise the discharge of all consignments.
A further A$1 million a year investment in improving animal welfare outcomes in the Middle East.


Get the facts: Caring for exports
Caring for animals is the number one priority for everyone in the livestock export industry; from farmers and transport operators to feedlot managers, stockmen, vets and exporters.
Farmers are committed to the wellbeing of their animals. They take pride in the quality of their animals, knowing that well cared for livestock are the most productive animals.
Australian farmers are interested in the welfare of their animals beyond the farm gate. They support the livestock export industry because they know it must comply with high standards of care.

Exporters make animal care their first priority. This is not only for ethical reasons but also to ensure they maintain the confidence of their customers.
They must satisfy their customers about the quality of the animals that are shipped and their wellbeing on arrival. If exporters fail to meet these strict requirements, they will lose money and contracts.

The public can be confident that exports are carried out humanely and safely. Everyone involved in the livestock export industry understands that there is a level of concern in Australia and other countries about the livestock export trade. The industry’s survival depends on the community and government having confidence that the trade is conducted with the highest standards of animal care.
These care standards are reflected in law. Strict regulations have been established with input from the industry, animal welfare bodies and government departments.
We lead the world with our standards of animal care in livestock export. The Australian industry has many years’ experience in the shipping of livestock. Recent research found we lead the world with our standards of animal care during export.
An independent report, published by Alliance Resource Economics in March 2006 and titled “World Livestock Export Standards”, found:
“Australia has world-best livestock export standards in terms of coverage and capacity to deliver acceptable outcomes.”
Strict industry standards have successfully improved livestock export. In 2006, 4.15 million sheep, 25,353 goats and 618,645 cattle were exported from Australia.
The 2006 success rates in export deliveries were 99.1% for sheep, 99.82% for cattle and 99.51% for goats. These figures demonstrate a significant improving trend over the last ten years.
We care: Animal care
Animal care is the first priority for everyone involved in the Australian livestock export industry.


During the voyage
All livestock export ships comply with the following strict standards:
Feed and water are constantly available to the animals during the voyage. Volumes are stipulated and checked prior to departure.
Animals have space to walk around and lie down in their pens.
To ensure fresh air, ventilation systems provide each deck of the ship with a full air change at least every two minutes.
Highly trained, accredited Australian stockmen support the crew by providing care to animals throughout the voyage.
A veterinary kit ensures adequate supplies of veterinary treatments if required.
Animals that become sick are isolated and cared for in special 'hospital' pens.
On arrival
When the ship docks, quarantine vets inspect all animals for illness and must sign-off on their health before they are unloaded.
The animals then spend a short time in a feedlot, where they are well fed and closely monitored to ensure they are in top condition before going to market.
The livestock export industry is investing both money and human resources into improving the way Australian animals are handled and processed in overseas markets.
This includes investing heavily in training the staff of local abattoirs and feedlots in the proper handling of our animals. In the Middle East this training is carried out by a dedicated team of animal welfare specialists based permanently in the region. To date this team has improved facilities across the Middle East and worked with importers, feedlot managers and stockmen to help them better understand how to work with Australian animals. This is part of a wider program involving liaison with Middle Eastern governments to ensure there are suitable standards and processes in place for how Australian animals are treated upon arrival in the region, as well as investment in new equipment and the upgrading of facilities.
