The goal ofthis program is simply to ensure the highestpercentage of saleable eggs free of externaland internal defects. Up to 1,000,000 eggs aretested every year in the Hy-Line Egg QualityLaboratories!Using the latest technology available and oftenpioneering new egg quality tests, Hy-Linehas set the standard to define Egg Qualityfor the layer industry. Unique and innovativeapproaches to testing and statistical analysisof the egg quality test results ensure thateach generation produces better quality eggs.This dedicated effort is part of the Hy-Linecommitment that egg quality leadership willcontinue into the future.Shell color is an important trait studied byHy-Line and significant advances have beenmade in recent years in the brown eggproducts. The extensive gene pool in Hy-Line’sResearch Program offers a wide spectrum ofoptions to continue to improve upon this trait.Hy-Line Brown Commercial Layer eggs rangefrom intense browns which score from 80 toover 100 in the scale shown above. Those yearto-yearaverage improvements are shown inthe chart above, top right.Hy-Line Brown Shell Color ImprovementsCOLOR SCORE INDEX9085807570651996 1998 2000 2002 2004 2006 2008 2010Another important egg quality measurement isthat of albumen height which is very importantin markets where raw egg consumption iscustomary. Also, Haugh Units (used to expressalbumen height) are used as a global indicatorof egg freshness. Eggs with higher albumenscan be stored for a longer time while stillmaintaining their fresh appearance whenused by the consumer. Long-term success inthe breeding program improving Haugh unitvalues is demonstrated in the chart below.Hy-Line Brown Albumen HeightImprovementsHAUGH UNITS9085807570+ 0.8 units/year+ 0.6 Haugh units/year651996 1998 2000 2002 2004 2006 2008 2010
