Diffuse reflectance spectroscopy reveals heat stress-induced changes in hemoglobin concentration in chicken breast
Abstract Heat stress (HS) is devastating to the poultry industry due to its adverse effects on animal well-being and performance. The effects of heat stress are typically measured using a portable i-STAT blood analyzer that quantifies circulatory hemoglobin concentration and other blood chemistry pa...

Abstract Heat stress (HS) is devastating to the poultry industry due to its adverse effects on animal well-being and performance.
