Using a Multi‐Attribute Decision‐Making Method to Evaluate the Effect of in Ovo Injection of Valine and Tryptophan on the Growth Performance of Broiler Chickens [PDF]

open access: yesVeterinary Medicine and Science, Volume 11, Issue 4, July 2025.
He multiple‐attribute method aids management decisions in in ovo nutrition. In ovo amino acid administration reduces embryo mortality risk late in incubation. In ovo injection of 0.55% L‐tryptophan on day 14 improves broiler growth. In ovo 0.55% L‐tryptophan significantly influenced growth metrics at 21 days.

Sex Detection in the Early Stage of Fertilized Chicken Eggs via Image Recognition [PDF]

open access: yesInternational Journal of Computer Science & Information Technology (IJCSIT) Vol 15, No 2, April 2023, pp.19-26, 2023
Culling newly hatched male chicks in industrial hatcheries poses a serious ethical problem. Both laying and broiler breeders need males, but it is a problem because they are produced more than needed. Being able to determine the sex of chicks in the egg at the beginning or early stage of incubation can eliminate ethical problems as well as many ...
