“…Recent estimations of the genetic basis have shown that the h 2 s of the myopathies are low to moderate (0.021-0.06 for DPM, 0.04 for SB, 0.024-0.097 for WB and 0.185-0.338 for WS), indicating that the non-genetic effects are the major influencing factor [81,86]. Understanding the non-genetic factors and implementing strategies to mitigate their impact has significantly reduced myopathy incidence in the field; these strategies have included technical advice on nutrition, bird management, and the handling of birds before, during and after bird processing [87]. It is possible, by taking advantage of the low to moderate h 2 s, to select against the myopathies while continuing to improve biological performance through balanced breeding [81].…”

This paper provides a comprehensive overview of the history of commercial poultry breeding, from domestication to the development of science and commercial breeding structures. The development of breeding goals over time, from mainly focusing on production to broad goals, including bird welfare and health, robustness, environmental impact, biological efficiency and reproduction, is detailed. The paper outlines current breeding goals, including traits (e.g., on foot and leg health, contact dermatitis, gait, cardiovascular health, robustness and livability), recording techniques, their genetic basis and how trait these antagonisms, for example, between welfare and production, are managed. Novel areas like genomic selection and gut health research and their current and potential impact on breeding are highlighted. The environmental impact differences of various genotypes are explained. A future outlook shows that balanced, holistic breeding will continue to enable affordable lean animal protein to feed the world, with a focus on the welfare of the birds and a diversity of choice for the various preferences and cultures across the world.

“…A newly identified muscle abnormality, known as spaghetti meat (SM), has also emerged, which has adversely affected the poultry industry [2]. Studies have indicated that the prevalence of SM can be as high as 20%, leading to adverse consequences on the composition, nutritional quality, and apparent attributes of meat [3]. This, in turn, results in a considerable reduction in meat value and significant economic losses owing to the need to downgrade affected meat products [4].…”

Spaghetti meat (SM) is a newly identified muscle abnormality that significantly affects modern broiler chickens, consequently exerting a substantial economic impact on the poultry industry worldwide. However, investigations into the meat quality and the underlying causative factors of SM in broilers remain limited. Therefore, this study was undertaken to systematically evaluate meat quality and muscle fiber characteristics of SM-affected meat. To elucidate the disparities between SM-affected and normal (NO) muscles in broiler chickens reared under identical conditions, we selected 18 SM-affected breast tissues and 18 NO breast tissues from 200 broiler chickens raised according to commercial standards under the same conditions for our study. The results showed that compared with the NO group, the muscle surface of the SM group lost integrity, similar to strip and paste. The brightness and yellowness values were significantly higher than those of the NO group. On the contrary, the shear force and protein were significantly lower in the SM group. Microscopic examination revealed that the muscle fibers in the SM group were lysed, necrotic, and separated from each other, with a large number of neutrophils diffusely distributed on the sarcolemma and endometrium. Thirty-five significantly different metabolites were observed in the breast muscles between both groups. Among them, the top differential metabolites—14,15-DiHETrE, isotretinoin, L-malic acid, and acetylcysteine—were mainly enriched in lipid metabolism and inflammatory pathways, including linoleic acid, arachidonic acid, phenylalanine, and histidine metabolism. Overall, these findings not only offer new insights into the meat quality and fiber traits of SM but also contribute to the understanding of potential mechanisms and nutritional regulators for SM myopathy.

“…These data are strongly suggestive that modern commercial meat-type chickens have decreased myogenic activity of their satellite cells which would reflect in decreased regenerative potential that may be associated with the development of necrotic and fibrotic myopathies like Wooden Breast. As put forth by Bailey (2023) , industry management strategies are now placing emphasis on maintaining optimal levels of satellite cell proliferation immediately after hatch to aid in the control of p. major muscle myopathies.…”
