Taurus bulls have again excelled in the August 2013 Logix Milk proofs, accepted by SA Holstein as the official Holstein analysis. With the big hype around the highest genomic bulls, we now have the opportunity to look at how the daughters of proven bulls have performed. The Holstein Merit Index (HMI), with the most weighting on Protein Yield (0.02*Milk + 0.12*BF + 0.31*Prot), has been developed. Other components of the indices, are Functional Herd Life (20%), Daughter Fertility (12%), Udder (8%), Udder Health (6%), Size (5%) and Feet & Legs (4%). These indices are expressed in Rand Value and indicate an animal's superiority or inferiority relative to that of the base cows. The change in index and analyzing organization resulted in a total make-over, including four new graduates to the top 10.
Top bulls give us confidence Justice is the commercial dairy farmers dream and leads the rankings with a HMI of R6 702. He eliminates all opposition with a figure of 4149 for herd life and 226 for daughter fertility. Add to this +721kg milk, and that he is the trait leader for chest width and udder depth, and you have an outstanding bull. His outcross pedigree of Wizard x Juror makes him easy to use.
Nokia is no longer alive, but the legend continues with +969kg milk and he is still the trait leader for butterfat, foot angle, rear udder width, medial ligament and udder health.
Nadal is loved in the TMR herds. He has powerful type, +512kg milk and positive percentages.
Shiraz is an exciting outcross of Sosa x Aeroline that breeds high milk (+801) from powerful cows.
Sam Rocket will appeal to pasture farmers with his medium stature and very high protein percentages.
Winn All breeds high protein from fertile cows.
Taranaki remains the top udder improver.
Talent Jumbo's high type outcross package is backed by +516kg milk and positive protein percentages.
New proven sires Nando graduates in second place with a HMI of R4 880. This Lou brother of Nokia starts with impressive yields of over 1000kg milk and has powerful type.
Tripsin joined the global success of the same cow family that produced Artes in Italy, and numerous other proven and genomic sires. Calving ease, balanced type and production, as well as an outcross pedigree will appeal to pasture farmers.
Taurie has kept his genomic promise of high protein production from longer lasting cows.
Shrek has also proved the reliability of genomic proofs. His smaller stature will appeal to pasture farmers.
The most promising sires for the next analysis, which are still a few daughters short is Koistory and White Gunn. White Gunn is the product of the creative mating of Baxter x Marion and breeds impressive butterfat yields.
No surprise that the highest genomic era sires are Jetson, at a mind blowing R9 053, followed by his brother, Jagger.
Whether you enjoy the rapid improvement of the genomic era or the confidence of daughter proven sires, Taurus can offer you the absolute best.
