BULLS OF DISTINCTION

Buying a bull is a genetic decision and not a financial one.” (Gerhard van Zyl. LBW)

At Econotech Simmentaler we combine genetics and economics by using appropriate economic selection indexes. Such an index gives one the Rand value of the contribution of underlying breeding attributes to profit. Thus, we use the Simmentaler Breeders Index (SBI) (mainly for breeders who farm with Simmentalers) and the Simmentaler Profit Index (SPI) which is based on the use of Simmentalers as part of cross breeding.

 

Our herd’s averages are R667 for SBI and R609 for SPI, which are in the top 5% of the SA 2019 crop.

Furthermore, to survive under our harsh conditions in the Karoo, we concentrate on fertility/reproduction. This implies a strong focus on moderate cow mass and milk, plus high body condition EBV's. (Exactly the breeding traits which Prof. Bob Weaber emphasized in his lectures on matching one's cows to the environment)  Eventually, we achieved an average 1st calving at 24 months of age for heifers (SA average = 31 months) and our herd’s average ICP (inter calving period) of a commendable 376 days (SA average = 440 days). The relevant breeding value for the main fertility indicator, Days to Calving (DC), for our herd amounts to -2.2 (this value is in the top 10 % of the SA 2019 crop). Calving Ease is also a necessity for farming on an extensive scale (Our herd's CED = 5.4, in top 10%).

(For more details on our breeding policy, please go to our notes in Afrikaans or English. See also a graph on how we have applied Bob Weaber's guidelines regarding reproduction under severe climate conditions to our herd)

 

Our bulls represent the best of our breeding policy. In addition they excel under veld conditions – only the most hardy ones are kept as stud bulls.

Two of our bulls have been selected as part of a short list of 16 top bulls in Southern Africa for a new AI bull, namely:

Klein Kalant P with a SBI of R722 and NFI-P of -0.12 (both in top 5% of SA 2019 crop)

Amri P with a SBI of R666 and DC of -2.0 (in top 5% and 15% respectively)

PJD 1565 P, KLEIN KALANT 1 P

He offers a rare combination of genes (Gonasty, Profeet, Zamuto and Kalhei). Two of his sons are still available.

Kalant, sire of young bulls - in top 5% of breed in feed efficiency. Results on graph of Phase C test - Glen station.

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

More information and graphs of Kalant's performance and pedigree is available. The longevity and fertility of his various dams in his pedigree forms the basis of his own fertility(ten out of the thirteen dams had six or more calves in their respective lifetimes). Furthermore, he passes more favourable body condition values to his progeny, which enhance their reproduction abilities.

Our 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. We manage to increase their expected genetic performance. This applies especially to their growth potential (400days EBV’s) without increasing their mature cow weight (MCW). Their details are attached in tables 7 to 10.

Econotech Dan S, PJD1743
Senior seedstock sire
R782 SBI (economic index)(in top 1% of SA 2019 crop)
Strong on fertility (in top 1% re SS and DC), calving ease (top 5%) and a low MCW.
Semen available.

dan 11sept_edited.jpg

Dan brings a different set of genes to our seedstock operation. He excels in reproduction traits which culminates in Days to Calving (DC) of -5.8 (in top 1%). This is coupled to strong body condition EBV's, a must for survival under a harsh environment. He is also a curve bender regarding growth with a EBV of 28 for 400days growth (top 40%) and a 25 for MCW(lower 20%).  As a result Dan's 2020-21 calf crop remain with economic indexes in the top 5% of the SA 2019 crop, but with improved fertility, e.g. SS and Days to Calving (DC).

More information on Dan's background and pedigree are available. The outcome of his genes on his latest batch of calves are very rewarding.
