GROBLER, H. J. F.; JORDAAN, J. W.  e  VAN DER RIJST, M.. Factors affecting the auction price of Veldram performance tested Dorper rams in Namibia. S Afr. Jnl. Agric. Ext. [online]. 2011, vol.39, n.2, pp. 1-14. ISSN 0301-603X.

Veldram performance testing has been conducted over a period of 14 years (1988 to 2002) at Kalahari Research Station in Namibia. During this period 2660 Dorper rams participated in 22 tests. Rams that met growth and breed standards were put up for auction at the completion of each test. The popularity of these auctions for performance tested rams (89.4 % of rams sold) indicate that Veld tested rams were sought after by buyers. The sale price of 296 Veld tested Dorper rams sold between 1994 and 2001, covering seven different tests, were compared with their measured and observed performances. Multiple regression and analysis of variance were carried out to determine which of the factors that were available to buyers significantly influenced price, as well as its contribution towards ram prices fetched. The contributing factors that had the biggest effect on price were Breed Classification (BC), Selection Index (SI), Average Daily Gain (ADG) and End test Mass (EM). This indicates that buyers did recognize the importance of performance data in selecting breeding rams and but most emphasis was on Breed standards (visual appearance). Although Breed Classification is the industry standard used by buyers, top ranking rams (stud) did not perform consistently/significantly better than flock rams.
