The US poultry industry hatches about 800 million eggs a year to produce hens for egg laying. Egg laying breeds are not used for meat production so male chicks are culled at 1-2 days of age. By developing methods to determine the sex of an egg early in development, eggs containing male embryos can be culled before the embryo can sense pain, increasing animal welfare. Early sexing also reduces industry costs.
Our approach uses high speed Volatiles mass spectrometry and machine learning to classify eggs as early as day 3 in development.
We recently purchases an Ionicon PTR-TOF 1000 Ultra Proton Transfer Reaction Mass Spectrometer are actively developing other applications for PTR-MS in agriculture including animal disease management and the processing of agricultural commodities.
