Beef breeding is a long-term investment and genetic improvement is difficult and slow. There are, however, so called advisors who present quick solutions to this involved scientific process. To be successful in breeding it is essential that all scientifically proven selection aids be used. There are three basic principles which are essential in the choice of a breeding sire, namely:
The visual appearance of the bull
His own performance
The visual appearance and performance of his siblings, especially his parents.
These three principles can be compared to the legs of a three-legged pot. The pot can only remain upright if all three legs are present. Any system, not based on all three these principles, has little chance of success in generating a profit in the long term. Furthermore, you must set an accurate breeding goal and then choose the correct bull according to your cow herd on the farm, to achieve that goal as soon as possible. Remember that early maturing and medium maturing type of animals’ round-off easier on the veld than late maturing types. What is your goal: veld or feedlot rounding off?
Choose functional efficient bulls. Such a mature bull should serve 35 cows within two months under veld conditions.
This requires the following:
Mounting ability (normal conformation)
Conception ability (normal and healthy reproduction system and semen production).
Own Performance and visual appearance By choosing bulls with the correct performance and visual appearance and of which the performance and visual appearance of siblings is also correct, progeny can be produced with similar traits for each succeeding generation.
What Is The Performance Goal Of The Progeny Of Such A Possible Herd Sire? a) Bull Calves
30 – 40 kg birth weight
Fast growth until wean (above average wean index – reflects the mother’s milk production)
Fast growth on veld or in the feedlot after weaning.
Medium to early maturing (round-off early)
Good carcass, conformation and grading.
High slaughter percentage
Good meat quality
30 – 40 kg birth weight
Fast growth to wean (good wean index = good milk production)
Fast growth on veld after wean (320 – 350 kg at 18 months = good adaptability).
Must conceive within 2 months in mating season
Must calve easily
Must have good mothering ability (enough milk, good udder and rear calf well until wean).
Must reconceive before her calf is 4 months old
Hereafter she must keep up this performance each year, but then reconceive before her calf is 3 months old.
Remember that the bulls reflect the vision which the farmer has for his herd for the following ±8 years. By studying a bull’s performance figures the performance of his progeny can to a large extent be predicted, since only heritable traits of economic value are taken into consideration, for example:
Birth weight – 40% heritable
Wean mass – 30% heritable
(Determining milk production ability of daughters)
Growth on veld – 30% heritable
Growth in feedlot – 55% heritable
Insist on records and official performance figures. It is important that these tests are done by a reputable organisation. In South Africa only the National Beef Performance Testing Scheme possess the necessary technology to do involved calculations such as estimated breeding values. Any breeder worth his salt, will always have them available. Soon all larger breed societies will be supplied with estimated breeding values for their animals, which will minimize the guesswork in the commercial industry. It is only available from official performance data and where sire and dam are known. Furthermore, this organisation can be objective since its officials are financially uninvolved in the industry itself. Because time is precious in genetic improvement, a breeder cannot afford to use doubtful bulls with the object of obtaining better bulls later. In the long run it will cost him dearly economically. By the time a breeder realizes that a mistake was made in the choice of bull (that is when his daughters wean their first calves), his progeny already make up a substantial percentage of the herd. After three generations 80% or more of the genetic composition of the herd comes from the bulls. Such reliable performance selected bulls are readily available. To calculate the value of a good bull within the economic limits of your own herd you can estimate it at the slaughter value of 4 – 5 slaughter cows from your herd. To produce outstanding breeding stock requires patience and dedication. It will be short-sighted and to your own detriment not to put this small premium on such an animal. Just think for example about the high premium that farmers pay for seed from excellent plant cultivars. No successful farmer will consider anything else. There is a saying: “Cheap bulls cost money and expensive bulls make money”. Buy the right bull to achieve the goal that you have set.
