Effects of Dietary Corticosterone on Yolk Colors and Eggshell Quality in Laying Hens [PDF]
Asian-Australasian Journal of Animal Sciences, 2015 The objective of this study was to investigate the effects of dietary corticosterone on egg quality. For 2 weeks hens received either control or experimental diet containing corticosterone at 30 mg/kg diet. Feed intake and egg production were monitored daily, and body weight measured weekly.

Yolk color measurement using image processing and deep learning
IOP Conference Series: Earth and Environmental Science, 2021 Abstract A high yellow yolk color of laying hens is required by customer. As yolk color measurement is determined by visual perception, color score may be expressed differently. The objective of this study was to develop the recognition of yolk color using red green blue (RGB) image and deep learning.
