Efficiency key to its breeding philosophy

Efficiency is increasingly recognised as one of the most critical challenges facing New Zealand’s beef sector, and for Mahuta Polled Hereford Stud it sits firmly at the heart of its breeding philosophy with an upcoming bull sale on 10 September.

Based south of the Bombay Hills and owned by John and Mary Allen, the stud has spent more than four decades refining a programme focused on producing cattle that convert grass into high-quality beef as efficiently as possible.

High calf survival, strong fertility and a condensed calving period are all central to that goal, alongside the ability to finish animals quickly and with minimal inputs.

High calf survival, strong fertility and a condensed calving period are all central, alongside the ability to finish animals quickly and with minimal inputs.

“We are aiming to breed the best animals in terms of converting grass to meat and for that meat product to be of the highest quality,” says John. “It goes without saying that good beef animals have to be structurally correct. An animal which breaks down is inefficient on multiple levels.”

He says studies in the United States have shown Herefords to be particularly effective at converting pasture into beef and Mahuta has built on that advantage by selecting for traits that reduce maintenance and environmental impact.

“We also aim for lower mature cow size which means lower maintenance – less feed and fewer greenhouse gases,” says John. “Cattle which finish earlier spend less time on farm, which again improves efficiency across feed use, emissions and overall cost.”

Another key trait is calving ease: “Dead calves are inefficient and calves requiring assistance cost time, money and lost production,” says John. “We aim for as much growth as our calving ease limitations will allow while also selecting for negative gestation to give cows more days in milk.”

He says Mahuta’s long-standing focus on fertility and performance is evident in its herd, which consistently achieves days-to-calving figures well above the breed average. Carcass traits are equally important with emphasis placed on animals that deliver higher dressing-out percentages and strong eating quality.

“Intramuscular fat dictates eating quality and means the carcass is likely to attract a premium, which increases profit per animal,” says John. “That is efficiency in its simplest form.”

These principles are reflected in recent genetic investments including the purchase of Matariki Performer P24 and Colraine Washington 23 421, the latter setting a spring sale record of $37,000 for a yearling bull. The first progeny of both sires will feature in this year’s sale.

At its on-farm sale, with online bidding available via Bidr, the stud will present its top line-up of yearling bulls bred specifically for heifer mating.

“These additions mean we are investing in the most productive genetics we can find, which in turn means the bulls we sell have higher-end productive potential and therefore profitability,” says John

Both sires rank highly across key performance indicators, including calving ease, growth and intramuscular fat, and sit in the top one per cent for beef heifer index, a combined measure of profitability.

“EBVs are an estimate of productive potential while indexes estimate dollar profitability,” says John. “Being in the top one per cent gives a strong indication of the value these bulls can deliver in a commercial system.”

Season’s Greetings from John & Mary

Season’s Greetings 2025 from John and Mary.

Hi everyone,

This is to wish you all a very Happy and relaxed Christmas and all the best for 2026. The season so far has been kind for us and we trust that it is for you too.

The fact that we are writing before Christmas is something of a record and we owe our level of organisation to our very good staff. We have Paul who is our new manager and Shane who is his assistant and we all work well together.

We hope that your bulls have done their job and we would appreciate your contacting us if there have been breakdowns.

We have realised that we don’t often have an opportunity to explain the aims of our breeding program and we hope that you don’t mind that we take this opportunity. This is important because bulls tend to breed to the average of the herd that they are bred from and so the aims of a breeding program are important in the purchase of any bull.

There is one key word that sums up our program and that is ‘efficiency”. We are aiming to breed the best animals in terms of converting grass to meat and for that meat product to be of the highest quality. It goes without saying that good beef animals have to be structurally correct. An animal which breaks down is inefficient on multiple levels.

To summarise the traits which we value:

1. Calving ease. Dead calves are inefficient and calves requiring assistance cost time and money and lost production (and so are inefficient).  

2. Growth. We aim for as much growth as our calving ease limitations will allow. Growth and birthweight are antagonistic traits and heifer-mating bulls require some compromise in terms of growth while allowing for safe calving.

3. Negative gestation is important for those requiring extra days for cows in milk and we aim for better than breed average

4. Meat. This is important as it is the product which is consumed and so the more meat an animal has the higher the dressed-out percentage and therefore more efficient. 

5. Fat and small mature size. These factors are important for early finishing especially if the season is not favourable. We aim for a mature-weight ebv below the 400-day weight ebv and we want an animal which grows quickly to around 500 days and then more slowly enabling it to lay down fat and so finish.

6. Intramuscular fat. This dictates eating quality and means that the carcass is likely to attract a premium which again means efficiency as it increases profit per animal.

7. And finally fertility means shorter calving interval and more cows in calf per bull.

8. Not to forget the controversial climate influence, animals with smaller mature size require less maintenance and emit less greenhouse gasses and animals which finish quickly are similarly efficient.

Thank you for reading this far. We hope that it promotes thought and we would welcome further discussion or enquiries about viewing the stock.

Wishing you all the best for 2026.

John and Mary Allen

Christmas Greetings 2024

Merry Christmas 2024 and Happy New Year 2025 Mahuta Hereford Stud

Hello everyone. The end of the year is rolling around again. Here’s hoping that you have had a good year.

The team at Mahuta would like to wish all our clients the very best for the Festive Season. We hope that you can get a break from the farm and are able to enjoy the company of friends and family. Farming is a very constant and draining job and it is important to get time away to maintain mental wellness. So, here’s to a good holiday with family.

Hopefully all the bulls have done their job by now. I am keen to hear if there have been any problems.

We wish you a Merry Christmas, a Happy New Year and all the best for 2025.

Fresh Bulls in 2024

Limehills Throne 220672

This year, we have bought 2 herd sires and a package of semen. They have all been purchased with the aim of furthering our breeding aims. These are to breed cattle which will maximise profit for our clients.

The first is Limehills Throne 220672. He is a very attractive bull, as can be seen from the photo, with great rein of neck and presence and mobility. In addition, his figures are outstanding which are an indication of productive potential and therefore profit. He has top calving ease [top 5%], above average growth, superior scrotal circumference [top 5%]. This is an indication of fertility. On top of that, he has above average EMA [meat], top 1% fats and top 1% imf [indicative of carcass quality]. Unsurprisingly, his indexes for prime beef and for beef-heifer mating are in the top 1% for Australasia.

The second bull is Matariki Performer P24. He is a very upstanding bull with great head carriage and rein of neck accompanied by high calving ease for the heifer’s calf, high scrotal circumference ebv and high meat, fats and imf.

The third is semen from Koanui Lips T147. He is rated by Chris Chesterman as one of the best bulls they have bred and he has data to match. We are looking forward to using him in our programme.

Christmas Newsletter 2022

Christmas Greetings and Newsletter 2022

Thank you to all who supported our 2022 sale. We had a great sale with a record high average price for NZ Hereford yearlings and a record top price for us selling lot 5 to the Craigmore Stud for $14,000. Thank you too to our loyal clients have bought in the past. We are aware that high prices can put people off and we aim to have bulls for everyone’s budget. We will offer more bulls in the sale to try and achieve this.

Mahuta Ocean 8073 continues to do well at the BLG/LIC progeny test. This is a multi-breed comparison with Hereford, Angus, and Simmental being involved.

Ocean was below average for birth weight [37.5kg over cows], 2nd shortest for gestation, shortest time for calves days-to-weaning, first for 200-day weight and 3rd for 400-day weight. Given the advantages of the Hereford Breed over other breeds, this makes him very valuable. Progeny will be offered at next-year’s sale. 

This year we have bought Matariki Night Rider. He is a low-birth weight bull [bw ebv 2.2] with growth top 15% and high ema and imf. He is very correctly structured and has a very dark colour. We look forward to his seeing his progeny.

I recently attended a dairy-beef open day focussing on Herefords. I was concerned that some of the dairy farmers did not really understand ebvs. This is important because it indicates how potentially profitable a bull is given the requirements of a farm operation and therefore how much you can afford to pay for him. NZ Herefords may have another field day next year but if not I am thinking of hosting one here. I would be interested in comments from anyone who might be interested.

Wishing you all the best for the Festive Season and next year,

John and Mary Allen
