Client Testimonials

Murray Long, Pendarra White Suffolk Stud, Ardlethan NSW:

We have been exclusively using the services of Livestock Breeding Services (LBS) since the formation of our stud in 1996. Both Michael and Michelle, and the various lab assistants they have employed during this time, have always been keen to assist in all areas of artificial breeding technology achieving some great results. We conduct an annual AI program of over 100 ewes, have numerous rams collected on a regular basis and been involved in several ET programs. The last 3 years AI programs have resulted in 91%, 92% and 87% conception on White Suffolk ewes during some difficult seasons.

Late in 1999, we made a decision to form a genetic marketing business, Performance plus Genetics which relies heavily on the expertise and dedication of all LBS staff to operate efficiently. This requires not only the collection of genetics to the highest standards, but the storage and distribution of these genetics to breeding centres all around Australia. All this has been conducted at LBS to the highest of standards and our business could not operate without the dedication of all at LBS. We have not had a single problem with semen distribution over that time and given the problems and panic that can potentially occur, this is testament to the dedication of all staff at LBS.

The advice provided by LBS in the area of artificial breeding technology has been responsible for improving the success of our breeding programs. In addition to this, they are prepared to listen to any concerns, ideas and problems and work through them to improve their techniques for all involved in the sheep industry. I recommend the services offered by LBS to all who wish to obtain maximum results and satisfaction from their breeding programs.

Graham Gilmore, Tattykeel Studs, Oberon

LBS have been our preferred team for AI since 1987. AI programs at Tattykeel are often large and complex with many breeds involved. 400-500 ewes are artificially inseminated each day with our best genetics, and we are looking to achieve the best results. LBS have delivered consistently high conception rates (in and out of season) with all of our breeds.

LBS has also been freezing semen in our top sires over the same period with semen quality always high, and our rams are always returned in great condition and good health.

I can recommend LBS to any breeder for the right results along with excellent service from Michelle, Michael and their staff.
