BULLS OF DISTINTCION

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 an appropriate economic selection index. 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 R612 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. Eventually, we achieved an average 1st calving at 24 months of age for heifers. The herd’s average ICP (inter calving period) reached also a commendable 376 days. The relevant breeding value for the main fertility indicator, Days to Calving (DC), for our herd amounts to -2.4 (this value is in the top 10 % of the SA 2019 crop).

(For more details on our breeding policy, please go to our notes in Afrikaans or English.)

 

Our bulls – the senior sires, young bulls (2+ years of age) and junior bulls (15+ months of age) – 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 R721 and NFI-P of -0.11 (both in top 5% of SA 2019 crop)

Amri P with a SBI of R667 and DC of -2.0 (in top 5% and 15% respectively)

SENIOR SIRES

PJD 1565 P, KLEIN KALANT 1 P

He offers a rare combination of genes (Gonasty, Profeet, Zamuto and Kalhei). Semen is 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 of his various dams forms the basis of his fertility. Furthermore, he passes more favourable body condition values to his progeny, but without diminishing their dams' high economic indexes.

Econotech Dan S, PJD1743

Senior seedstock sire

R782 SBI (economic index)(in top 1% of SA 2019 crop)

Strong on fertility (in top 5% re SS and top 1% re DC), calving ease (top 5%) and a low MCW.

Semen available.

Dan brings a different set of genes to our seedstock operation. He excels in fertility and calving ease. He is also a curve bender regarding growth with a EBV of 26 for 400days growth (top 50%) and a 22 for MCW(lower 15%).  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.

YOUNG BULLS

Our young 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. Three of these bulls are still available, namely PJD1836 (Gert), PJD1910 (Potter) and PJD1912(De Ruyter). Their details are attached in text and tables 3 to 6.

JUNIOR BULLS

We manage to increase the expected genetic performance of our 2019 set of junior bulls. This applies especially to their growth potential (400days EBV’s) without increasing their mature cow weight (MCW). Their details are attached in text and tables 7 to 9.

 

One of our junior bulls, PJD1950 P, Amri, has gained the distinction of reaching the short list of 16 bulls in Southern Africa, one of which to be selected as the Society’s new AI bull.
