Poultry lighting
Light is an essential aspect of poultry production. In most housing systems, artificial light is utilized to maximize production in pullets, layers and breeders. Today, a variety of different bulbs are available to illuminate the inside of a poultry house, all of which have benefits and shortcomings. Understanding the different lighting options available for poultry, as well as the terminology and management of light, is essential to achieve the best production. Light is critical for egg production and pullet growth. Domestic poultry see and respond to a different range of light color spectrum and have different spectral intensity responses than humans. While humans respond to light from around 400–750 nm, chickens can see UV-A light (315–400 nm) in addition to 400–750 nm. Additionally, the magnitude of sensitivity for red and blue spectra is much higher for chickens with additional peaks of light sensitivity around 480 nm and 630 nm.
INTRODUCTION Genetic selection programs emphasizing broiler growth, breast muscle deposition, and feed efficiency traits over the past 30 yr have led to a rate of change that has not slowed (Havenstein et al., 2003a,b). Photostimulation ( PS ) age, feed allocation, and BW profile of the maturing pullet can all effect nutrient partitioning between growth and ovary development (Robinson et al., 2007). Renema et al. (2007b) reported that, as a percentage of BW, Ross 708...

I. INTRODUCTION The physiological patterns of hen FI and BW trajectory are established by early lay (Muir et al. 2023a). Careful management of lighting and feeding patterns during rearing can regulate bird size and feeding habits by the end of rearing (Muir et al. 2023b). Whether this influences persistency of lay, efficiency of production and egg quality during an extended laying period is unknown. The lighting program during rearing can alter pullet age at first egg (AFE), the...

Adult chickens utilise external circadian cues to schedule their daily cycles. In other taxa, developing embryos can actively entrain the timing of life transitions to a circadian rhythm (Villamizar et al., 2013, Saunders, 2002), but we currently have a poor understanding of how circadian rhythms develop in meat chicken embryos. Commercial poultry are not exposed to diurnal light changes during incubation, removing the possible use of such cues for optimising hatch timing. Synchronising...

Damaging behaviors in poultry include feather pecking, vent pecking, and toe pecking. While feather and vent pecking are well-known welfare problems in poultry that have received significant attention from researchers and farmers, toe pecking remains relatively unknown.

Description of the problem Broiler chicks are typically exposed to continuous or near-continuous light for their first week of life (Scanes and Christensen, 2019), a practice supported by many broiler management guidelines (Aviagen, 2018; Cobb, 2021). The rationale behind this approach is to provide chicks with ample time for feeding during their rapid growth phase. However, the effectiveness of continuous lighting for modern fast-growing broilers during brooding remains...

Reviews made on the impact of intermittent lighting (IL) on broiler performance (Buyse et al., 1996; Rodrigues and Choct, 2017) attest to the consistency of such lighting programs in achieving better feed conversion rates. So far, no research has been conducted to assess the impact of IL on the susceptibility to and recovery from infectious diseases. We hypothesized that an IL program would increase broiler resilience to necrotic enteritis (NE). In order to test this hypothesis, a 2 x 2...
