Benchmarks

For more effective utilization of individual herd data, production benchmark values utilizing the NCBA-IRM-SPA calculations were obtained from CHAPS^TM herds with a total of 70,000+ cows exposed to bulls and processed during 2003-2007. CHAPS^TM compares each individual producer's performance against the benchmarks. The benchmark values for the NCBA-IRM-SPA traits are as follows:

SPA		CSF
Pregnancy %	93.5	ADG	2.52
Preg Loss %	.73	WDA	3.01
Calving %	92.8	Birth Wt	87
Calf Death Loss	3.03	Adj 205 Day Wt	637
Weaning %	90.8	Frame Score	5.8
Replacement Rate	14.9	% Heifers Early	35.9
CD Loss Based on # Born	3.18	% Heifers at 21	71.7
Average Age at Weaning	189	% Heifers at 42	86.5
Calves at 21 Days	64.3	% Cows at 21	63.4
Calves at 42 Days	89.2	% Cows at 42	86.5
Calves at 63 Days	95.7	Cow Age	5.7
Calves After 63 Days	4.34	Cow Wt	1395
Steers WWT	565	Cow Condition	5.7
Heifers WWT	546
