SEMEN AND EMBRYOS

Genetics for advancement of beef cattle

The judicious use of semen and embryos provide the cattle farmer with cost-effective tools to upgrade his or her herd with leaps and bounds.

 

The best from our herd of Simmentalers have been selected for semen and embryo production. This process is done at an international accredited veterinary station according to stringent quarantine and testing procedures designed to meet export requirements.

Semen from three of our bulls are available:

  • Klein Kalant, PJD1565 P, a polled sired renowned for feed efficiency, superior growth and fertility. Kalant has been selected to be part of a short list of sixteen bulls in Southern Africa for a new AI bull. (See more on Kalant as sire and his pedigree)

  • Dan, PJD1743, has been selected for outstanding fertility and calving ease breeding traits, as well as moderate growth coupled with a low EBV for mature cow weight. (See more on Dan as sire and his pedigree)

  • Sizwe, PJD1226 P, polled and the sire of Kalant P, has a proven record of producing a high negative Net Feed Intake (NFI-P) EBV. He combines this with a strong positive body condition. In his pedigree are two renowned sires, namely Jozette Gonasty PP (Best Proven Bull in Southern Africa for 2018) and Kwantum Profeet (with a NFI-P = -0.09).

  • The semen is also available as either sexed male or female semen.

  • The semen is collected by Ramsem (Pty) Ltd, a world renown animal reproduction laboratory in Bloemfontein, South Africa. We make also use of their Sexing Technologies Laboratory for sorting semen in either male or femal semen.

Our embryos are produced from three distinct set of matings:

  • Embryos sired by Kalant from the three dams in the program should excel in growth (in top 15-25% of SA 2019 crop for 400days growth), but with a lower mature cow weight (MCW)(between top 35% and 40% of SA). They should also have high EBV's for calving ease (in top 5%-15%) and fertility (Days to Calving DC in top 5%-25%) plus being highly feed efficient. One set of embryos (Kalant x PJD1633) should reach the top 1% of the SA 2019 crop re overall economic selection indexes (SBI as well as SPI). More information is available in Table 2.

  • Dan’s embryos from a set of three dams represent higher calving ease (in top 1%-5%) and fertility (DC in top 1%-5% and SS in top 5%-15%). These embryos should have lesser growth (in top 45% for 400days growth) than Kalant’s embryos. They demonstrate bended growth curves with an average of 26 for MCW (in lower 25%). The overall economic selection indexes of the embryos range from 1% to 5% of the SA 2019 crop. More information is available in Table 3.

  • Sizwe’s embryos from the dam, PJD0917, should provide us with replicas of Kalant – negative Net Feed Intake, high Calving Ease and fertility plus strong growth and body condition. Both parents, Sizwe and PJD0917, come from a line of fertile dams with nine out of thirteen with 6+ calves. PJD0917 herself boasts with nine calves and is pregnant with her tenth calf. More information is available in Table 6.

  • The embryos are also available as either sexed male or female embryos.

  • The embryos are processed by Absolute Genetics (Pty) Ltd from Bloemfontein.

 

Semen from Kalant and Dan as well as embryos from Kalant mated to PJD103 are now available on order. (Attached are the pedigree of PJD103 and more info on her embryos)

 

Our dam, PJD103, has already produced six out of nine calves which have been registered. Two of these, a 1st calf cow PJD1812P and a young bull calf PJD2028, were sired by Kalant (photos are attached). Each of her female offspring had their calves at 24 months like their dam. A very fertile cow family indeed.

 

Embryos from the other dams will only be available after they have calved from September 2021 onwards.

Kalant P x PJD103 produces embryos that should excel in Net Feed Intake.

In addition to Kalant's high Net Feed Intake (in top 5%) the various sires in

PJD103's pedigree have also very high Net Feed Intake EBV's.  

Furthermore, PJD103 hails from a cow family noted for their longevity and

fertility. One example is her dam, PJD051, with 11 calves at an ICP of 403 days. PJD103's embryos should have bended growth curves with their 400days at 25% of the SA 2019 crop, but with their MCW EBV's at 38 (35% of SA).

The dam, PJD1633 P, has sires in her pedigree that demonstrate high Net

Feed Intake. This, coupled to Kalant's high NFI should produce embryos 

with similar high NFI's. Her dam, PJD0716, was an exceptional fertile cow with 11 calves at an ICP of 364 days. Again PJD1633's curve for growth should be bended from 34 (400days in top 15% of SA) to a lower MCW of 37 (in top 40%).

1/4

PJD1721 P comes from a very fertile cow family, which includes her dam, PJD0719, with 12 calves and an ICP of 367 days. Her great grandmother, PJD9513***, was a three star cow with 8 calves at an ICP of 368 days. Embryos from PJD1721should have growth curves that are bended from a high 400 days (15%) to a lower MCW of 36(in top 40%).

The dam, PJD1447 P, is one of the best with economic selection indexes (SBI and SPI) in the top 1% of the SA 2019 crop. Her embryos sired by Dan should maintain this high standard. Dan will most probably improve PJD1447’s EBV’s regarding body condition and fertility (DC to increase from -3.0 to -4.3). The growth curve of her embryos should also be bended from 29 at 400 days (in top 35%) to a low 28 regarding MCW (in the lower 30%). The attached photo of the bull calf, PJD2036 P, (sired by Dan x PJD1447), is an excellent example of this proposed mating.

1/4

Mating PJD1456 P to Dan should retain the high EBV’S for calving ease of the dam. Dan, on the other hand, will most probably increase the fertility (DC = -3.5, in top 5%) and the body condition of their embryos. The growth curve of the embryos should also be bended from 25 at 400 days (in lower 45%) to a even lower 27 for their MCW (in the lower 25%). The attached photo of the heifer, PJD2023 P, (sired by Dan x PJD1456), is an excellent example of this proposed mating.

The embryos from the mating of Dan x PJD179 P come from two families with outstanding longevity. Six out of the seven dams in the pedigree of Dan had seven or more calves. In the pedigree of PJD179 P five of the seven dams had eight or more calves. The embryos should also show similar high breeding values for Calving Ease, Days to Calving (DC) and body condition such as EMA and Fat. Although the embryos should demonstrate lower mature cow weight (in the low 25%) their 400day growth should be up in the top 40%. In total their economic selection indexes should be in the top 5%.

Embryos from this mating, Sizwe P x PJD0917, should, first and foremost, have high negative Net Feed Intake. The embryos also join the high EBV’s for calving ease and fertility from Sizwe (CED=7.9 and SS=1.0) with PJD0917’s fertility (DC= -2.9) and longevity (9 calves over a life of 12 years and in calf at present). They have each strong body condition EBV’s (EMA and Fat), which strengthen their ability to thrive under harsh extensive conditions. Furthermore, PJD0917’s bended growth curve culminates in the embryos probable EBV for 400days of 28 (in top 40%) and MCW of 30 (in lower 35%). The outcome of this joining are embryos with qualities which underpin high economic selection indexes (SBI and SPI both in the top 5% of the SA 2019 crop).
