Genetics
Kia Ora Stud has developed one of the world’s largest repositories of Wagyu semen and embryos, most free of negative recessive genes. Our collection is held in approved collection facilities and strengthened by a selection of more than 90 different bulls and over 100 cows.
Our success and quality is grounded in science. Working closely with veterinary scientists, selective breeding over generations has enabled us to remove the negative recessive genes known to Wagyu. Every calf is genetically tested and any showing signs of negative traits are excluded from our breeding programme. As a result, we are able to offer genetics completely free of negative recessive genes.
Since we’ve done all the hard work, using Kia Ora Stud genetics dramatically reduces your risk. You don’t even need to own a bull (you can hire one from us or purchase semen straws or embryos).
Kia Ora Stud semen is proven to deliver 95-98 percent calving success in comparison to the industry average of around 75 percent.
Why are traits important?
Traits are critically important in Wagyu breeding because they directly impact the quality, marketability and profitability of the beef.
The genesis of genetic perfection.
Early on, we learnt that Wagyu success is not only about the family tree, so we looked closely at Wagyu genetics. We decided to work towards removing all the negative recessive genes by only breeding bad-trait-free animals. Having largely achieved that goal, we then focussed on marbling and growth. The success of our approach is proven.
Kia Ora Stud steers participated in a Sapphire feedlot trial for around 400 days to review their performance. Our animals scored 5th in weight gain amongst dozens of breeders. The trial showed that our animals have an average daily gain (ADG) of 1.3-1.4kg eating 8-9kg of feed. We kept some control animals after the trial and they continued to gain weight at the same rate in our own feedlot on return from Sapphire. Our system works.
