Julia Aspinall
Julia Aspinall, principal of Genetic Gains Ltd. has specialized in animal breeding since 1985 and has been heavily involved in some of New Zealand's most intensive genetic reproduction operations.

These include a large angora goat programme, LambXL's "New Breed" Quarantine, Silver stream's East Friesians, Tara Hills' Superfine Merinos and numerous on-farm programmes. Julia has a B.H.Sc., M.Sc. and NZIM Dip. Mgt. Genetic Gains was established in 1995 and is based in Invercargill, New Zealand. In 1999 Genetic Gains became a registered company, Genetic Gains Ltd.

-  For the New Zealand market
Genetic Gains Ltd. produces a ram semen catalogue featuring genetically superior sires. Romney, Coopworth, Texel and Suffolk are the main breeds represented, but other breeds are also included.

  • All rams featured in the catalogue have been proven to be genetically superior either by sire referencing, progeny testing or some other comparative trial. This ensures that the genes offered are from among the most productive rams in New Zealand.
  • The catalogue is distributed to farmers in New Zealand who have shown an interest in AI. To order a catalogue, please email post address.
  • Having the ram featured in the catalogue is a free service for breeders, who benefit from the advertising, the recognition of having bred or purchased an elite sire and revenue from semen sales.

For the International Market
NZ has a wide range of sheep genetics of a very high quality. Overseas breeders are invited to specify their requirements for ram semen. Genetic Gains Ltd. will then find the donor animals which meet these requirements and process the semen according to the appropriate export health protocol. Quotations on request.

Genetic Gains Limited leases the Woodlands AB Centre premises, 22 km from Invercargill. The Centre is licensed by Bio security New Zealand (registration number NZSOC03)  for export. Rams are health tested before being admitted to the Centre and are frequently monitored for live weight and general health. Breeders can be sure their valuable sires are receiving very good care. Our animal and laboratory technicians are extremely thorough, and ensure a very high standard of quality control is maintained.

          Services provided by the AB Centre include

 

  • ram semen collection / processing for domestic use / export.
  • semen storage.  Phone 03 2163455
  • semen dispatch. from outside NZ 001164 3 2163455.

Genetic Gains Ltd. will continue to provide these services and
will strive towards continually improving the quality and
range of services offered.



Genetic Gains Ltd. and Premier Genetics NZ Ltd. work together, offering on-farm breeding / genetic reproduction services for sheep. Intrauterine (laparoscopic) Artificial Insemination (AI). The average conception rate is 75% (with frozen-thawed semen).

(MOET).
The average embryo hold rate is 75%. A very specialised laparoscopic embryo recovery technique is offered. This highly skilled technique subjects the valuable donor ewe to a minimum of trauma, and allows repeated embryo collections with a much reduced risk of permanent damage compared to the traditional surgical technique.
 

These courses are designed for sheep farmers who have a small number of genetically superior sires on their property which they would like to use over large numbers of ewes. Do-it-yourself Cervical AI Courses are held on request for a minimum of 4 and a maximum of 6 people per course. A comprehensive manual is included, and at the end of the one day course participants are fully competent to carry out cervical AI on their own sheep. Ram Semen Collection Courses are held on request for a maximum of 4 people per course. This is also a one day course including a comprehensive manual. It covers ram semen collection and handling, processing for immediate use and field assessment.


Handheld logger used for SIL recording (performance recording) for our national sheep database. Genetic Gains Limited operates an animal recording bureau for Sheep Improvement Limited (SIL recording),
our national sheep database.


Julia Aspinall  (principal of Genetic Gains Limited), Wendy Ophuis  who has been involved with animal recording since 1992, and Janene Greig are committed to making the animal recording process as user friendly as possible.

We recognise that as a breeder, you spend a lot of time and effort collecting records, and that accurate data entry and reports are therefore very important. Gene Capture ... Our hand held data logger for efficient and accurate sheep recording.
 

          

  • If you have not been involved with SIL recording before, we explain to you why it is important for ram breeders to belong to the SIL database, discuss which records are of most benefit to you, when to record them and how to make the best use of the reports.
  • We offer you the option of recording manually using paper pre-lists which list the IDs of the relevant animals in your flock, or electronically using Gene Capture, our hand held data logger with a programme especially developed for SIL users.
  • We recognise the fact that as a breeder, you spend a lot of time and effort collecting records, and that accurate data entry and reports are therefore very important. We double check every record we manually enter onto the database, and communicate with you about any mistakes in records e.g. duplicate lamb tags.
  • Gene Capture users receive a 20% discount on our services, improved accuracy of record collection, and save you hours of time. The Gene Capture programme has special features for individual requirements e.g. multiple flocks, prefixes for Texel lamb tags etc.
  • We tailor-make reports to suit your individual requirements, and suggest options which may be of benefit to you.
  • We prepare a newsletter containing topical and technical information three times a year, and are very willing to discuss your breeding programme with you.


Use of rams achieving an average rate of genetic improvement (compared to no genetic improvement) results in an increase in cumulative net profit of tens of thousands of dollars for an average sheep farmer over ten years. Use of elite rams (compared to average rams) can more than double a breeders rate of genetic improvement as well as cumulative net profit (see graph below). AI and MOET helps breeders to achieve a rapid rate of genetic improvement and thus high value ram sales. AI with frozen-thawed semen allows use of elite sires even after they are injured or dead.
