Abstrakt:	First-week survival and egg hatchability are lower in chicks from younger broiler breeder hen flocks. Creatine is a naturally occurring compound synthesised from the amino acid arginine or obtained from the diet and is important in the storage and transport of energy. Previous research found an improvement in the hatch rate but no posthatch performance improvements when fertile eggs from young breeder hens were injected with creatine monohydrate (CrM) on embryonic day 14. This pilot study aimed to further investigate the possibility of early posthatch improvements by examining the activity of chicks during the 1st week posthatch. Behaviours were broadly classified as active or inactive, the pen was split into three areas, and the amount of time spent in the heat lamp, feed hopper, or drinker line areas was recorded. Chicks given in ovo CrM spent less time in the heat lamp area over the whole 7 days compared to saline (t = 2.352, P = 0.021) and control groups (t = 3.336, P = 0.003) and more time in the feed hopper area during the first 4 days compared to the control group (t = 2.174, P = 0.033). This finding suggests that creatine may improve energy reserves in young chicks allowing them to spend more time away from the heat lamp. (Copyright © 2024 The Authors. Published by Elsevier B.V.
