Skin breaking strength in broiler chickens
… contributing to skin strength of meat-type chickens. Skin breaking strength was initially measured in lines of chickens divergently selected for high (H) and low (L) juvenile body weight, their reciprocal crosses (HL and LH), and an F₂ generation derived from HL and LH matings. Skin of …

Towards the modulation of the microbiome to control Campylobacter in broiler chickens
… Campylobacter and the microbiome associated with broiler chickens are little understood. Therefore, a series of studies were designed to fill that knowledge gap with the long-term goal of modulating the microbiome to deter Campylobacter colonization in broiler chickens. Chapter I reviewed the …

The Effect of Jungle Light Spectrum on the Fearfulness of Commercial Broiler Chickens
… of the topics of most interest is how commercial broiler houses are lit. There is discussion about high intensity light (50 lux), natural light from windows compared to conventional dim lighting programs (2 – 5 lux) using “white” LED light. Chickens are prey animals that depend on their vision …
