Coopworth Rams
Season Update
The 2017 season has been exceptional in regards to rain fall and grass growth. Summer dry is the norm for us so we try to farm accordingly. March tupping is usually challenging as it is often when feed covers are at their lowest and low quality and ewes are often losing weight. Our philosophy is to produce sheep that can handle the conditions without supplement, with ewes on a no drench policy, rebounding quickly after a tough season. This season was not the norm as we had rain every week and had great feed covers but also the challenges that come with moisture and humidity - high parasite loads. This year we did not have the high FE spore counts we usually see in the autumn. A complete opposite to 2016 ! The ewes were in great condition and have shown no adverse effects from the parasites nor FE. Tupping was in March and 90% of ewes marked in the 1st cycle. MA ewes scanned at 210 %.
Hogget lambing
Hoggets are farmed exclusively on grass. We strongly believe that by successfully mating hoggets on grass we are developing genetics to perform in any environment. This season has been an exceptional one for grass growth and the hoggets averaged 4o Kg going to the ram in early April. They scanned at 154 % - the highest ever. We have clients , using top feeding and management, who are achieving consistent hogget scanning rates of over 150 %. They are realizing the full genetic potential of these sheep.
Hogget lambs were bigger this season and therefore more were put to the ram. It is a challenge most years getting hogget lambs up to tupping weight by April as they are Sept/Oct born. The only dry hoggets retained in the stud flock are those that are themselves hogget lambs, these must produce twins at their 2th lambing.
Longevity
At the other end of the flock are the old ewes. Longevity is highly valued and Nikau has a ' longevity mob ' of aged ewes- 6 yrs plus. These are Nikau genetics; commercial ewes with consistent twinning and solid feet, mouths and constitution.
An old ewe in this environment is the gold in the flock. She has never been ' on the radar' and has survived and produced through drought, FE, parasites and all the other challenges our areas has. This mob is mated to top Nikau rams with the goal of producing daughters to screen into the stud flock. This a another source of female genetics based on longevity and performance.
A select group of rams will be available for sale.
Facial Eczema Tolerance
Flock sires are all Facial Eczema (FE) tested at .6mg/kg . FE testing has been done for the past 33 years. Nikau Coopworth is an FE Gold flock, leading genetics for Facial Eczema tolerance.
We also GGT test all ewe and ram hoggets each summer in the face of natural challenge to assess them for FE tolerance. It is very important to be screening out the intolerant females as well as dosing the sires.
GGT is an enzyme released in the blood that is apparent when liver damage has occurred. This gives an indication of an animal’s tolerance to FE. All animals with elevated GGT are culled from the stud flock. All sale rams have had no elevation in GGT to this seasons high challenge.
We are farming in a very ' hot ' FE area, meaning we see spore counts each autumn. The GGT screening one of the most important tests we do.
Screening our ewe flock this way, dosing all flock sires at 0.6mg/kg of sporidesmin and farming in such a challenging area gives us confidence that we have one of the most FE tolerant flocks in the country.
2016 was one of the hottest FE years on record yet many Nikau clients reported higher than average lambing results. With top FE tolerance they were able to take advantage of the good feed available.
SIL ACE
Nikau features highly on the SIL ACE DPX list. This index is a assessment of FE tolerance, however the ACE run does not take dose rate into account. Look at the star rating to differentiate flocks testing at different levels.
5 * is the highest level.
The new NZGE on SIL shows Nikau genetics to be at the top for health traits, FEC and FE. Selection for over 30 years for a strong immune response has rewarded us with top rankings on SIL with over 1100 flocks in the evaluation.
Sheep Industry Awards
Nikau Coopworth - Maternal Trait Leader fro Parasite Resistance.
Nikau has had a strong focus on parasite resistance. The ewe flock as been no drench since 2002. Lambs are on extended drench intervals and selection is based on above average performance with exposure to high parasite challenge.
Rams
Selection is based on the use of DNA to assess heritable traits, ultrasound CT muscle scanning, fecal egg counts, GGT testing , frequent weight taking and wool weights.
Rams are sold by auction at the Tuakau Saleyards in early November. They are presented in index order with the first draft of approximately 60 rams having a Reserve Price of $1000. 2nd draft $750, 3rd draft $500.
