“…However, although birds fed algal oil diets had similar eggshell quality values to those fed the standard diet, some surprising differences existed between birds fed algal oils. Previous research reported conflicting effects of feeding n-3 FA-enriched diets on eggshell quality; for example, reduction ( Attia et al, 2022 ) and no effects ( Neijat et al, 2016 ). As expected, feed intake, HDEP, FCR, egg weight and egg mass increased with hen age ( Hanlon et al, 2022 ).…”
