Herdsires – ARCHIVED

Redstone LBR0302herdsires_Redstone

‘Spook’, as we referred to him, was the backbone of our breeding programme for many years, having followed us to four properties in the early days!  He was acquired in dam at the Rigby’s dispersal sale in 2003 when we still operated as Redstone Shorthorns.  We acquired him on our 2007 dispersal sale and he eventually landed up as senior herdsire at Forest Glade in Alexandria for a number of years.  He impressed from birth with his masculinity, thickness, length and depth of body.

His daughters form the backbone of our young cow herd and we have retained a number of sons over the years as herdsires.

We will have a number of grandsons in our 2014/5/6 Bull Sales and we still have a mature son, Duncraggan Sultan 096, on loan to a herd in the Cathcart district until we need him back for a further infusion of genetics.

Duncraggan President 049 herdsires_DPresident

A masculine, spring 2009 son of an appendix Weebollabolla purebred bull, that came in dam, from the Carnarvon Dispersal sale in 2009.  He impressed with his low, 35kg, birthweight and excellent Wean, Yearling and 18-Month weight indices.  Excellent, long, soft hindquarter muscling completed the package!

His progeny have impressed with good growth after easy calving and low birthweights, and we will have a number of sons available on our 2014 and 2015 Bull Sales.

His female progeny are especially impressive, showing excellent femininity.

He sold to Chris Sheard of Cathcart for R14500 at our 2012 Bull Sale.


Duncraggan Ronin 073 herdsires_DRonin

An Autumn 2010 son of Tukulu Lochinvar 747, out of a Nonen Hutton daughter.  He showed extremely good balance as a youngster.  Paternal grandson of Tukulu Ladysmaid 65, a cow that always weans one of our heaviest calves.

We used this bull in Spring 2011 and Autumn 2012 and then offered him on our 2012 Bull Sale where he sold for the top price of R24500 to Brosterlea Shorthorns, Molteno.

We will have a number of sons available in our 2014 and 2015 Bull Sales.

Shadybrook Scotty 83K herdsires_ShadybrookScotty

Rated in the top 1% for calving ease, 2% for milk, and top 10% for low birthweight in the American Shorthorn Association Fall 2013 EPD data.  Shadybrook Scotty 83K also rates in the top 1% for $CEZ, top 2% for $BMI and top 15% for $F indices.  He has been used in the USA, Canada, Australia and South Africa.  His May 2014 Australian BreedPlan figures indicate that he is a trait leader for 400-Day Weight, Milk, Carcase Weight as well as Retail Beef Yield EBV’s.  He is number six for EMA in the breed and a son is number one in the breed.  He is sired by Deer Trail Buckshot 5073, out of a tremendous female, Miss Scarlet 10W, who was in the donor programme at Shadybrook Farms, Canada.  Scotty has impressed all since birth with his stout make up, smooth, fault-free design and exceptional performance, on a moderate frame.

Our top performing bull in our mature cow herd progeny on our 2014 Bull Sale is a son, D. Thatcher 163.  We have retained another son, D. Tarantino 159, as our junior herdsire.  He also has a grandson for sale in our 2014 Bull Sale, D. Tetric 182, by D. Obvious 0806.


The Main Meneer: Duncraggan Smashing Stuff 103 – ARCHIVED

As we see stock like this on the ground, we are comfortable we are moving in the right direction with our herds. We picked Smashing Stuff out as a youngster, and briefly wrote about him in the autumn 2012 edition of our newsletter. We have kept him largely under wraps since then, with a few guests at our open day last September taking a walk to view him. Now he has featured brashly on our “A lot of bull” advertising campaign.


The top of his pedigree is Spry’s breeding at its best. He is a Spry’s All Gold D052 son who has all the legends of this preeminent Australian breeder consistently throughout the generations. Neearra Judith 104, who has become one of the leading donor females in the Spry’s programme, is as near to perfect a female as one could find, comes through strongly as a female line, with the ‘legendary’ JR Legend 78H also in for good measure.


Smashing Stuff’s dam, Redstone Sunbeam 0553, from our original Redstone herd, has a strong Nonen and Rozetta-via-Rigby’s influence with the well-known South African genetics packed in thick. Quite interesting to note is that John Rigby imported semen from Spry’s Zambesi II (GLSG22), and this bull appears both in the top and bottom sides of Smashing Stuff’s pedigree.


Smashing Stuff grew well from birth, with the trait-leading 200 day weights of his sire expressing themselves clearly. He has always been thicker than his contemporaries with superior weights, and as he matures, his frame has moderated, and he has become even wider, in line with the breeding values of his sire. We don’t want a bull or a herd that gets too big in mature frame size.

We used him autumn 2013 for the first time as an 18-month old to pick up all we missed with the timed AI. The AI calves are falling as we speak, but we do not have any pick-ups from him yet. These should come through in the next 2 to 3 weeks or so. Again over November and December we used him, and the photos in this article were taken just before we took him out on 04 January.SS4

He is just 30 months old now, and we expect him to make a huge contribution to our breeding programme, as our main sire, over the years to come.


The Stockman has landed! Crooked Post Stockman 4Z, our new impact sire, is here – ARCHIVED

Six months in the making, and finally the semen has arrived in South Africa for our autumn 2017 joining. We did some serious research to find the best genetics for our operation, and Stockman 4Z more than fits the bill. 

From Kirk Seaborn’s world-renowned Crooked Post Shorthorns in west-central Alberta, Canada, come genetics from a programme that has always been focused on the development and promotion of Shorthorn genetics towards the commercial beef market. The herd is not for show – it is performance oriented, relying on staying ahead of the demands of breeders worldwide.

Says Kirk, “We have adopted the use of genomics for over 15 years, ultrasound scanning of all yearling male and female progeny for 16 years and whole herd performance recording since our inception; only about one or two other herds in North America have applied these management tools for as long and as persistently as Crooked Post over the last 20 years. Our main promotion is towards the production of breeding bulls for commercial clients. Their feedback to us has always been integral.

This is music to our ears as we continue to strictly performance measure our herd as well, together with a rigorous hand/ eye assessment for structural correctness and functionality attributes of all our animals. To remain ahead of the curve, Kirk continues, “Just in the last few days the very first Genomic Enhanced Expected Progeny Differences (GE EPD) have been released by International Genetic Solutions (IGS). Some of our sentinel animals have been issued these GE EPDs. Once I’ve provided the American Shorthorn Association with our last 2-3 years of Igenity Profiles we will be well underway in utilizing this next big step in performance documentation. Crooked Post has conducted more genomic identification than any other Shorthorn herd in Canada and possibly N. America. It is really time to take the next big step!” As a result of Crooked Post’s innovative programme, Stockman 4Z’s latest IGS EPD update finds him now to be a trait leader for CED (Calving Ease Direct) and also for $BMI (British Maternal Index).As you may be aware, we work very closely with Ian Walsh from the Falkirk Scientific Foundation based in New Zealand, who plays an integral role in our herd development and selection process. He is aligned with our vision to produce cattle that are functionally efficient. He helps us monitor and predict the trait ability of our animals to their maximum, and then to understand their constraints or exceptionable abilities. He studied the video and photographs of the Crooked Post Shorthorn Stud and made some observations that helped our decision-making process.  He reported that “Stockman 4Z appears to be medium framed with excellent depth particularly the shoulder and girth region.  His mobility suggests a correct structural configuration with a full but smooth and optimal shoulder formation.  Stockman 4Z’s muscularity is ideal with ample expression illustrated.  A well-balanced sire that deserves consideration for your stud as an improver.”  This is especially encouraging as Ian cautions that we should only introduce new genes from a proven impact sire after stringent consideration. With Ian’s kind of input, we are sure you will understand why the Falkirk System is so supportive for us as breeders.

Further to the above input, we evaluated Stockman 4Z based on his sire line genetics, his dam line, and his offspring already on the ground in Canada.

Starting with the sire line, Kirk noted how Stockman 4Z would work with our current genetics: “I strongly feel that Stockman 4Z would contribute very positively in your program and would complement the sires that you are utilizing.” We have looked at this issue closely, and it is important to note how the genetics dovetail to a bull we used from Canada a couple of years ago, namely Shadybrook Scotty 83K. We do believe that tightening up genetics no doubt increases consistency and predictability of the offspring – in line with the expectations of return commercial bull buyers who are either chasing consistency in their herds or trying to maximise hybrid vigour in a cross-breeding operation. (By the way, have you noticed how people talk about and pursue the maximisation of hybrid vigour in their programmes, but at the same time purchase composite or far from pure bulls to use in their programmes?)

Some other significant genetics which are included in Stockman 4Z’s pedigree include Byland Gold Spear and Waukaru Gold Mine.  These are also commercially oriented herds that to date we have been unable to get into South Africa.

On Stockman 4Z’s dam’s side, the Red Rose family is one of the key lines. Says Kirk, “It’s a key family here at Crooked Post. It’s been a great family to work with and one that we’ve made improvements to through the years. Stockman 4Z is a result of this work and for this reason why I suggest that he’s a step or two ahead.” This is evidenced through the dam’s outstanding performance figures below.

Stockman 4Z Progeny

Stockman 4Z has been used heavily at Crooked Post for four breeding seasons already, and has quite a number of progeny on the ground. Ian Walsh also critically evaluated Stockman 4Z’s heifers and commented to us as follows: His group of heifers are uniform and mobile with desirable form to function in any environment.  The pelvic setting is well illustrated as an optimal birthing canal to cater for desirable birth weights to contribute to high survivability and productivity.  The general impression of all the females observed from this stud is desirable with the attributes as described for Stockman 4Z … Longevity and high productivity ooze from these animals.

There are several significant purebred and commercial herds around the world that are and will be using Stockman 4Z. After the evaluation and doing the sums (our rather insignificant ZAR does not go very far these days) we decided to purchase the semen and marketing rights for South Africa. We will use him extensively for a number of years to come, with the view that he will make another significant improvement to our herd – certainly in the same manner our previous “big buy”, Sprys All Gold D052, did for us.
