In Neuseeland, dem größten Schaffleisch-Exporteur der Welt, hat man sehr auf die Ausprägung der wertbestimmenden Bestandteile - Keulen und Rückenmuskel - geachtet.
Die neuseeländischen Suffolkschafe sind etwas größer als die britischen, ohne daß der US-amerikanischen Irrweg über die für die Schlachtlammproduktion nutzlose Show Line  nachgeahmt wurde. Das führte dazu, daß die Böcke sich durch eine sehr starke Keulenbemuskelung und eine auffallende Körperlänge auszeichneten. Die Ultraschallmessung ergab darüberhinaus eine sehr starke Ausprägung des Rückenmuskels (M. Longissimus dorsi). 
Da die Nachfrage nach Knochen zumindest bei den menschlichen Verbrauchern nicht so stark ist, wurde in Neuseeland auf die Züchtung von übermäßig starken Knochen verzichtet. Dies geschah auch vor dem Hintergrund, daß die Ablammungen in den Riesenherden in Neuseeland unter natürlichen Bedingungen draußen und weitgehend ohne menschliche Hilfe erfolgten.
Diese Ablammbedingungen haben auch zu einem weiteren Effekt geführt:
Sie erfolgen leicht, die Lämmer sind sehr vital, d.h. sehr schnell auf den Beinen
und suchen sofort das Euter, um zu saugen.
Da auch in Deutschland die Herden immer größer werden und die Arbeitskräfte teurer, sind "pflegeleichte" Schafen, die in der Ablammzeit wenig Arbeit beanspruchen, von großer Bedeutung.

Unser 2010 und 2011 eingesetzte Zuchtbock Roseden President stammt aus der schottischen
easy-care-Zuchtrichtung, deren Zuchtziel ist in Anlehnung an die neuseeländische Suffolkzucht:

leichtlammige und fruchtbare Schafe,
wie in NZ soll ein Schäfer 1.000 bis 1.500 Muttern betreuen können.
Lämmer, die bei der Geburt irgendwelche Hilfe benötigen, werden
deshalb nicht zur Zucht genommen.
Neben der
Leichtlammigkeit, Fruchtbarkeit und guten Muttereigenschaften
sind aber besonders die
Tageszunahmen bei Weidehaltung sowie der
geringe Fettansatz und die Bemuskelung von großer Bedeutung.

      Origins and Development of NZ-Suffolks                                 

Origins and Development of New Zealand Suffolks

Introduction

These are based on UK bloodlines. Whilst the first UK Suffolks went to New Zealand in 1913, the majority of imports occurred in the 1940s-1050s with the sheep coming from leading UK flocks, which in those days were based in East Anglia.

Why New Zealand?

If you consider the current and future requirements of a typical UK commercial farmer then N.Z. Suffolks tick every box including:

bullet Fast Growing
bullet Long Living
bullet Hard Working
bullet Low Maintenance
bullet Requiring Minimum Labour

N.Z. Suffolks originated sixty years ago from UK bloodlines that, in turn, had been developed over hundreds of years to meet UK conditions and meet UK needs. The hardiness of the Norfolk Horn allied to the meat producing qualities of the South Down have produced in the Suffolk a world class star in terms of productivity and rapid meat production.

N.Z. selection in a low labour input environment means that the modern N.Z. Suffolk meets the needs of the modern UK sheep farmer.

Differences

Although originating from an identical genetic base 60 generations of selective breeding means NZ Suffolks differ in many ways from current UK Suffolks.

Physical:

NZ Suffolks have
 

bullet finer heads
bullet less bone
bullet finer shoulders
bullet fine hair

NZ Suffolks are

bullet taller
bullet longer
bullet less thick especially at the shoulders

Management:

bullet Most NZ Suffolk flocks are at least 200 ewes
bullet Most NZ Suffolks run alongside commercial flocks, many 10,000 ewes +
bullet Lamb outdoors
bullet Lamb unaided
bullet No concentrates
bullet Culling for lambing difficulties
bullet Foot problems including foot rot
bullet No foot trimming
bullet No nitrogen on grass (use high clover levels)
bullet Close relationships with customers
bullet Private on farm sales
bullet Recording – we only source from full SIL recorded flocks.

       EasyRams Selection

 EasyRams Selection/Management Protocols

All EasyRams will be reared managed and selected with the aim of meeting the following prerequisites.

EasyRam Traits

Long living

We aim to sell shearling rams that will work for at least 4 seasons.

Hard working

Our rams will be capable of serving 120-150 ewes per season (as mature rams ie shearlings and older).

Easy lambed

bullet The skeletal shape with the front wedge and fine shoulder shape will guarantee that your EasyRam sired lambs will lamb on their own with minimum labour input.
bullet NZ Suffolks are considered EasyCare and hardy and this is proved by trials in NZ showing.

In New Zealand Suffolks are Number 1 for live survivability.

"At Poukawa Research Station over the past 5 years the Suffolk X lambs have had a mortality rate of 3.2% compared to an overall mortality rate of 4.9%, placing the Suffolk as the best breed examined. (49 sires were used in the trial producing 4,182 lambs of which 1,081 were Suffolks)."
 

Vigour

bullet Pure NZ Suffolks lamb outside and are not assisted at lambing. They are used in flocks where sheep have to lamb unassisted. (One supplier runs 22 Suffolks rams with 3,000 Romneys. These Romneys are part of a 10,000 ewe flock all lambing on their own).
bullet EasyRams are selected for vigour at birth and will have vigour records.

Hi vigour lambs
 

bullet Get up quickly
bullet Suck quickly
bullet Have less malpresentations at lambing
bullet Have better survivability

Survivability

All NZ Suffolks have genetic figures indicating whether their offspring are more or less likely to survive to weaning than the breed average.
Easy Rams will measure and publish this trait.

Foot Rot Resistance

EasyRams will have figures for genetic resistance to footrot (samples will be analysed) using NZ DNA testing at Lincoln University – Christchurch, NZ.
Foot-trimming NZ sheep are bred so that they should not require foot trimming. (Those requiring foot trimming – are culled). Our records will show if any trimming has been required.

FEC Worm Resistance

Dung samples will be taken to measure EasyRams resistance/resilience to worms.

Management Protocols

  1. Lamb in spring
  2. Sell rams as Shearlings
  3. If lambed indoors turn out within 48 hours of birth
  4. Rear on grass
  5. No concentrate use
  6. Winter on natural forage – no supplementary feeding
  7. 2nd year feed on grass alone
  8. Full records kept of performance, management traits, physical characteristics
  9. Females will be lambed for the first time as ewe lambs.
  10. Rams sold with
    bullet warranties for :
    bullet ability to serve 120 ewes/season
    bullet life expectancy re performance/health
    bullet performance health history
    bullet MV Accredited status
  11. No trimming/carding or tampering with of the wool will be permitted.
  12. Franchisees must be members of and sheep be registered with the Suffolk SheepSociety. Registration provides automatic recording of pedigrees performance and health data with BASCO
