OUR PHASE C BULL TESTING

You can’t understand if you don’t measure
What you don’t measure you can’t control”

THE IMPORTANCE OF FEED EFFICIENCY

Production efficiency is a function of inputs and outputs. In a cattle production system the biological efficiency it is the quantity of feed that the animal consumes to produce one unit (Kg) of meat. Feed intake and feed efficiency is therefore an important component of production costs. Phase C testing is the only performance phase where feed intake is measured on individual animals to evaluate feed conversion. The direct measurement of feed intake to calculate feed conversion, is the most accurate method to determine the breeding value for feed efficiency. Breeding values that are estimated (according to Leslie Bergh) bases on the correlation between ADG and FCR, are inaccurate.

 

IMPORTANCE OF PHASE C TESTS

Apart from the cost of the weaner, the feeding cost is the biggest cost in the feedlot. FCR is therefore a critical trait in the profitability of a feedlot and it becomes more and more critical as the cost of feed increases.

 

SERNICK PHASE C BULL TESTING STATION.

The Sernick Bull Testing Station has a capacity to test 200 bulls at any one time and with three cycles per year, it has the capacity to test 600 bulls per year.

Since 1990 over 9000 bulls have been tested including over 3000 own bulls. During this period the FCR of the Sernick bulls has been improved by 1.2 kg per kg weight gain while the ADG has improved by 200 gram per day. At the same time the height has been reduced (smaller animals) and the length has been increased. At current feed and meat prices, these figures represent a difference of almost R1200 per animal in the feedlot which is significant and which illustrates the importance of FCR and hence Phase C testing.
