Our bulls are reared on the veld under harsh Karoo conditions. Only the very hardy are provided to our clients. You get what you see.

Kalant, sire of young bulls - in top 1% of breed in feed efficiency. Results below of Phase C test - Glen station.

Research has shown that a 10% improvement in feed efficiency can lead to 43% improvement in profit.

Apart from being in the top 1% for the breed in feed efficiency, the graph on the right shows Kalant is in the top 15% of calving ease, top 10% re 400 day growth and the top 20% for 200 day growth.

A set of 7 bulls from our Econotech Simmentaler Seedstock are really a showcase of consistent breeding. During the pre-mating season we took meticulous care in choosing the correct bull for every cow to be mated.

The outcome is most rewarding:

  • Fertility: One major breeding attribute for fertility is Scrotal Size (SS)(a sign of breeding early puberty under heifers). Two of our bulls have EBV's for SS in the top 5% of the SA 2018 herd.

  • Calving Ease and Birth Weight: Through out our seedstock operation a high calving ease and a low birth weight are considered as essential for our no-nonsense-extensive-farming-system. The present set of bulls are proof to this with an average EBV for CED (calving ease direct) of 4.8 (in the top 10% of the SA 2018 herd) and a EBV for birth weight of 0.8(in the top 20%).

  • Growth: One has to consider the pros and cons of concentrating on growth regardless of other attributes or the other way round. We try to take a balanced approach with more emphasis on fertility and calving ease than any other factor. However, growth has not been neglected and the bulls have an average EBV of 29 at 400 days (in the top 30%) and an average Mature Cow Weight (MCW) of 37 (on average in the top 35%).

  • Two bulls are sired by Econotech Klein Kalant P (awarded a silver merit at Glen with a Net Feed Intake(NFI) of -0.401 – this was based on Kalant consuming 2.5 kg feed less than a similar size bull, but with both notching 2.3 kg mass gain per day over the Glen test period). These bulls should, therefore, have the same tendency for being feed efficient than their sire, Kalant. The five other bulls have also, but of a lesser degree, feed efficient bulls in their ancestry. To us, struggling in the harsh Karoo, feed efficiency is the answer to scarce resources and the ravages of climate change.

  • Economic Indexes: The Simmentaler Breeders Index (SBI (R)) takes the economic contribution of all the relevant breeding attributes into account. According to the SBI our set of bulls come out tops with an average of 647, which is in the top 10% of the SA 2018 herd. At the same time the bulls' SPI (an index measuring their contribution to cross-breeding) are on average 597, which is in the top 5%.

  • Polled factor: The polled factor is most important to us. Not only does it cut down on labour, but polled cattle are also more docile and therefor more efficient feeders. Five of the bulls are polled. Three of the bulls may even be homozygous polled, having both their parents polled. 

  • These bulls are fully registered and their sires validated through DNA analysis.
