January Embryo Transfer Program Recap

February 21, 2022

Bar H has just recently undergone an embryo transfer (ET) program with 'The Repro Group' from Allora. The program took 19 days to complete and consisted of 2 mobs that started one day apart from each other. In each mob there were 7 donors and just over 80 recipient cattle. 

 

Mob 1 donors consisted of a number of poll and purebred cattle, these were AI'ed to BAR R 52Y (PB13914)(P) with the intention to create polled females. Mob 2 donors consisted of fullblood cattle which were artificially inseminated (AI'ed) to a variation of bulls, consisting of Yasafuku Jnr KB1271, Shigeshigetani, Itoshigenami, Itomichi ½, and Blackmore Aizatzurudoi Y398. Some of these joinings are new combinations to the Bar H herd, and have been specifically generated with the intention to create both males and females. 

 

Donor mob 1 excelled producing a total 82 transferrable eggs between them which allowed every recipients to receive a fresh embryo. Close to 65% of these embryos were quality A and the other 35% quality B. Donor mob 2 didn’t respond as well, producing less than 50% of what donor mob 1 did. Whilst somewhat disappointing, this allowed us to use some frozen embryos, both homegrown and purchased, reintroducing some exciting genetics to the herd.

In total, there were 163 recips selected based upon the following variables; 

  • Aged 3-3.5 years old – they have proven their fertility and size, however they’re still young enough to carry an embryo with ease. 
  • Wagyu groups F2 and F3 - they have the benefits of the fertility that accompanies the Wagyu breed, even though they will have lower content than a full blood or pure bred, they will produce more milk, calve easier and are proven mothers. 
  • They're proven cattle, and if an embryo doesn't take, then a mop up bull will still produce an extremely good calf, that fits in with our production guide. 


An interesting moment during our program was on flush day 2, where Peter Atkinson from ‘The Repro Group’ and his staff realised that six excess embryos from the day before had been incubated for over 24 hours and grown nearly two stages over night. As an experiment for both of us, we decided to implant these embryos into a select group of recipient animals, which are being closely monitored to track how these embryos grow. This is an exciting collaboration for our business. 


Peter believes he is experiencing the most business he’s ever seen, he says that “during the drought it slowed down a bit, but last year was the biggest year we have ever done”. ET in cattle is becoming more realistic and accessible for wagyu breeders, not to mention how much it’s demonstrating to improve people’s herd.


Some of the following joins were flushed and transferred during our ET program:

BAR4C249 X IMUFQT148 - The reason these two animals were joined was because of C249’s blend of genetics that opens all doors. Having my favorite bloodlines in (DM100 & J003) allows this cow to be joined to anything. C249’s progenies have out preformed the average weaning weight for us and she always shows mass milk supply, even at 15yrs of age. TF148 was selected to produce us either a female or male.


BARFK1634 X WKSFS0100 – This is an exciting join for our business, I chose this because of this massive cow’s high growth and milk traits throughout her genetic makeup, allows in a 100% Tajima bull like Yasafuku Jnr. This joining makes available a very balanced Wagyu progeny male or female. – her previous three generations in growth and milk accepts that bull


Y3272 X BRCPG0052 – This is an unusual join, with Y3272 not being registered with the AWA, she has proven to be an asset to the Bar H herd. The reason these two animals were joined was because to focus on a poll purebred that are bred, born, and grown in Central Queensland. Near 10 years ago we purchased some of Lock Rodgers Wattle Top Angus F1’s, for this project, I AI’ed Itoshigenami, Mahashi, Katusumi, Kanyhama, Michitatsu and Itozurudio to these F1 cows, to establish a strong F2 female foundation. Y3272 is by TF151, and to infuse 52Y with this pedigree is an exciting join.

PAPFH1144 was purchased by Bar H Grazing from Trelinga’s David Peak as a twelve-month-old weaner bull at the end of 2013. He was purchased for his genetic makeup – a heavy maternal cow base being 40/1, over Haruki 2, over Kikuhana – all of that complemented by TF148 who consistently allows his females foundations to perform, the way they’re meant to.

In a world where monetary value is significantly weighted as the key indicator of success, it can sometimes become difficult to remind ourselves that progress comes before value. It is important for us as cattle producers, businesspeople, as well as parents and friends to learn how to measure key indicators of progress.

2022 at Bar H Grazing was a significant year for the team and business. It saw the crew move from strength to strength and focus on establishing a strong foundation for years to follow. It was a year dedicated to the future of the business – seeing multiple projects that have been in the pipeline come to fruition and pave the way forward for years to follow.

If you take a drive through River Lea during a muster, odds are you will see dogs working with our operations team on horseback, getting the job done. I sat down with our Operations Supervisor Andrew Jansen to talk about why we use this tried and true method of working dogs and horses and the benefits that we reap from this combination.

Morphology is a multipurpose tool that provides a variety of benefits to suit the individual needs of your enterprise. A motility score is a familiar semen test and provides some related information however morphology represents a very important part of a bull breeding soundness evaluation (BBSE) (Australian Cattle Vets Association, 2013).

Recipient cattle used in embryo transfer programs, vary from herd to herd and can be difficult to calculate. The appropriate sorts of recipient cattle in our herd differ, and their importance is significant, in some opinions more than donor cattle, since this is the animal that’s required to conceive the embryo, carry it to full term, and raise the calves ​(Lamb & Mercadante, 2017)​.

Prepare, perform, and persevere. These 3 P’s were the running theme of the Young Beef Producers Forum held at Roma in mid-November, attended by three members of our team. Amongst all the informative speakers, a key takeout was the necessity of preparation. Whilst this is far from being a foreign concept, it is a tool that can be continually implemented and improved on.
workers on farm using technology

In the Bar H Grazing Autumn Newsletter, we wrote about the process of making the staff at River Lea replaceable, and the value we have found it to have in our business. The different technological tools we use on-farm have assisted us in doing so. We have employed the principles of data collection at River Lea, only capturing data we can utilise and act on. Technology for us is only a tool not something we rely on. Labour has been a major beneficiary in having access to technology all over the property. Not only monitoring water supply, but also pinpointing the location of an issue - we can be notified instantly.

I was playing the long game when I decided to purchase some F1 Angus from New South Wales, with the intention to create Bar H Poll foundations. These Wattle Top Angus Wagyu heifers mixed with the natural Polled Bos Indicus females already in our herd would set the basis for us. Using known genetics over these females gives me confidence in producing Bar H Purebred Poll Wagyu with data I can touch. It has been proven to me that Wagyu has the ability to have the full package - in production and carcase with welfare.
