DKL had a negative correlation (p < 0.05) with the TC (R = −0.54), M0h (R = −0.19), PM0h (R = −0.42), and NM (R = −0.40). TUD had a positive correlation (p < 0.05) with TC (R = 0.51) and with NM (R = 0.32). Thus, boars with higher tubular density produced a higher number of sperm cells with fewer morphological abnormalities, while boars with a higher number of grey pixels showed the opposite. Since DKL can be measured at 22 weeks of age, it could be the trait of choice for early selection of boars for productivity. This early selection could reduce the costs of semen production. Further research is needed to define the genetic basis of these traits, assess their relevance for breeding programs, and evaluate whether echotexture parameters can serve as objective markers of puberty onset in boars.]]> https://www.frontiersin.org/articles/10.3389/fvets.2026.1829423 https://www.frontiersin.org/articles/10.3389/fvets.2026.1829423 2026-05-05T00:00:00Z Brief Research Report Morgan S.

The magnitude of this variability exceeded any detectable effect of embryonic sex and highlights the dynamic and heterogeneous nature of early embryo development in pigs. Consideration of this biological variation should be of high importance when designing and interpreting studies investigating early conceptus physiology.]]> https://www.frontiersin.org/articles/10.3389/fvets.2026.1819023 https://www.frontiersin.org/articles/10.3389/fvets.2026.1819023 2026-05-05T00:00:00Z Original Research Radia BouhamedTaha-Mossadak HamdiCemil KurekciHerbert TomasoHeinrich NeubauerHosny El-Adawy https://www.frontiersin.org/articles/10.3389/fvets.2026.1774228 https://www.frontiersin.org/articles/10.3389/fvets.2026.1774228 2026-05-05T00:00:00Z Original Research Jiale ZhengFan LeiShiang LiuYaqin ZhaoZiyu ZhangBaoxia DongHuina FengHaixia Jing https://www.frontiersin.org/articles/10.3389/fvets.2026.1798669 https://www.frontiersin.org/articles/10.3389/fvets.2026.1798669 2026-05-05T00:00:00Z Review Edwin Oswaldo Botia CarreñoMona Mohamed Mohamed Yasseen ElghandourPasquale De PaloAristide MaggiolinoMaria De AngelisAbdelfattah Zeidan Mohamed Salem https://www.frontiersin.org/articles/10.3389/fvets.2026.1789084 https://www.frontiersin.org/articles/10.3389/fvets.2026.1789084 2026-05-05T00:00:00Z Original Research Zikai GuoXiaoran WangDanwei CaiZhennan GuoPi ChengJianguo ZengHua LiuYisong Liu https://www.frontiersin.org/articles/10.3389/fvets.2026.1755025 https://www.frontiersin.org/articles/10.3389/fvets.2026.1755025 2026-05-05T00:00:00Z Original Research Maria Ines CrescioCristiano CocumelliAzzurra CarnioAndrea CarvelliNiccolò FontiAitor Garcia-VozmedianoValentina GaliettaClaudia EleniFrancesco IngravalleElisabetta ManualiCarmen MarescaFrancesca MillantaElisabetta RazzuoliPaola ScaramozzinoSara SimeoniMarta VascellariClaudia ZanardelloGiuseppe Ru https://www.frontiersin.org/articles/10.3389/fvets.2026.1761652 https://www.frontiersin.org/articles/10.3389/fvets.2026.1761652 2026-05-05T00:00:00Z Original Research Juan A.
