Eight pregnant Simmentaler cows available
Mainly polled from outstanding sires, calving December through to February 2021
Top world genetics + Stringent selection = value for money.
A group of eight cows are available. They are sired by a variety of outstanding bulls, such as Gonasty PP (Zoetis Southern Africa Proven Bull for 2018), Prostock Hugo PP (USA), Salerika Bravo P (a BGP bull), Erico Napoleon P and sons of Gonasty and Hugo. These cows are all polled, except two which are horned. They are pregnant from our own bred bulls specifically chosen to improve the genetic make-up of each cow. Their calves should be born from end of December 2020 to February 2021.
These eight cows excel in fertility. Thus, their breeding values (EBV’s) for Scrotal Size (SS) and Days to Calving (DC)(parameters for fertility) are on average in the top 20% to 30% of the 2018 crop. Their Inter Calving Period (ICP) averaged at 391 days and their Simdex at 107, which also give an indication of the fertility status of these cows. Furthermore, they have on average high EBV’s for calving ease (in the top 30% to 10% for CED and CEM respectively). In total their economic indexes are on average in the top 20% for both the SB
(breeders) and SP (cross breeding) indexes.
Through judicious bull selection we hope to achieve a vast improvement in the planned calf crop of these cows. Seven of the eight cows have been sired by Econotech Dan S, a son of Simberg Zolerz. Dan is especially strong on fertility and calving ease. He is also able to keep growth intact, while lowering the MCW of planned calves. Thus, fertility is planned to increase by 70% and 110% regarding the EBV’s of the planned calves for SS and DC respectively. Calving ease of the calves should increase up to 50% over those of their dams and their birth weight should be lower with 25%. However, growth should only increase fractionally (3% for 400 days), but with a decrease of 10% in the mature cow weight (MCW). In summary, the average economic indexes SBI and SPI of the calves should increase with 13% and 7% respectively, which put these indexes in the top 10% of the SA 2018 crop.
One planned calf (that of PJD1457) has been sired by Kalant P. This means that this calf should have the added benefit of being sired by a bull with a Net Feed Intake (NFI) of -0.401 (in the top 1% of the SA crop). The calf should, therefor, have the same tendency for being feed efficient than its sire, Kalant.
