1 Introduction The understanding of the genetic parameters for reproductive traits is crucial, as females must have a high farrowing rate but also ensure that their offspring reach at the weaning age (Kobek-Kjeldager et al. 2020). Among reproductive traits, those related to litter size, such as total number born (TNB), number born alive (NBA), and viable piglets at Day 5 (PV5), hold significant economic value in pig production.

Abstract Cultured meat is considered a sustainable protein alternative. To produce chicken meat in a controlled environment, bacterial nanocellulose (BNC) was used to provide structure similar to traditional chicken meat. BNC was synthesized as a hydrogel from Novacetimonas hansenii in vitro culture. Chicken mesenchymal stem cells (MSCs) from pathogen-free eggs were cultivated in both 2D (monolayers) and 3D (spheroids) forms and introduced into BNC.
