AviLighting Abstract

Effect of AviLighting Feeder Lights, Water Lights, & intermittent lighting on antibiotic-free broiler progeny & pullets 0-21 day live performance when reared on litter bedding at time of housing to 3 weeks of age. M. Barnas1, M. Roberts1, J. L. McNaughton1. 1AHPharma, Inc. Salisbury, MD.

Previous studies have shown that regardless of light source, <6% of broiler chickens & breeder pullets are actively drinking during the first 24h post placement, thus, reducing early body weight (BW) gain & BW uniformity (BWU). Due to accelerated growth rates, 7-21d BW & early mortality (M) have a large impact on overall bird performance. Three trials were conducted to determine if bird attraction to nipples influences 24h water consumption (WC) & M in weaker-flocks. Two 15m (50’) x 10m (32’) 750-bird rooms with fresh pine-shaving litter bedding were used: Chamber #1a: AviLighting™ Water Lights (AWL, 0.5W LEDs between nipples) with feed trays underneath, and AviLighting™ Feeder Lights (AFL, 4.8W LEDs that sit atop feeders); Chamber #2b: standard ceiling LEDs (SCL, 6W A-19 type).

In all three trials, either combined or individual light sources over weakly-hatched & antibiotic-free birds, AWL & AFL presented a stronger bird attraction to light plus feeding/drinking behavior due to contrasting light intensity (deltafc >10 between light & dark area). Initial 24h use of AWL proved the historical null hypothesis that chicks are attracted to deltafc >10fc & that both water & feed underneath AWL are essential. Intermittent lighting (toggling each 4h between AWL & AFL on 3-4d) resulted in birds migrating from water to feed within 30min. After 4d, AFL attracted birds to the feed & water areas for the next 2d, before the birds spread throughout the house. WC significantly (P<0.05) increased when AWL was employed, as compared to SCL group. No differences were found in 0-21d F:G, or 21d litter moisture (all <27%). Due to increased WC with the use of AWL+AFLa, significant (P<0.05) improvements vs. SCLb in 0-7d were: BW (166ga vs. 158gb), mortality (<1.2%a vs. 3.7%b) & BWU (9.96%a vs. 11.13%b CV). The same statistical trend was found in 21d live performance data.

Bird Attraction Study

Over the past week, we have documented the activity of 800 birds in our research facility to determine their attraction to the AviLighting feeder light. The results were similar to what we’ve been seeing since day one, with one new discovery; birds that are pushed out into darkness manually (running away from a human) will move right back into the feed/water area to return to the light. This indicates that birds are attracted to the light, and furthermore, allows us to get creative with brooding schematics…I.E. we can now test a whole house brood, with no curtains/walls and lights on one side of the house only. This may sound strange, but video evidence shows that birds won’t venture out into the darkness and get lost when food and water readily available in the light.
