It is used as aguide to making breeding decisions. Breeding Worth estimates are comparableacross herds, ages and breeds.An estimated Breeding Worth of +$100 indicates that using this animal asa parent of a replacement is expected to generate an extra $100 profit peryear per 4.5 tonnes of dry matter consumed, compared to using a parentwith a BW of zero.DMCRMGDDKKLWGMEMSNPTDry matter.Comparative relative maturity, a rating of the maize maturity. High valuesindicate that the crop will take longer to mature.<strong>Growing</strong> degree days, a term used to describe the accumulated days whenthe average temperature is over a certain base temperature. For maize,GDD’s are calculated using a base temperature of 8 o C.GDD = (max + min temp) - 82Potassium, when referring to nutrients.One thousand, when referring to plant population. 89 000 plants per hectarecan be describe as 89K/ha.Liveweight gain.Metabolisable energy, a measure of feed value.
