Abstract
To evaluate the tolerance of a high-fiber diet in Erhualian pigs (Er-HL), the present investigation systematically investigated the ramifications of varying wheat bran fiber levels, specified as total dietary fiber (TDF) values of 14.07%, 16.32%, 17.99%, and 18.85%, on growth performance, fiber digestibility and gut microbiota in Er-HL, large Large White pigs (L-LW, the same physiological stage as the Er-HL) and small Large White pigs (S-LW, the same body weight as the Er-HL). Our results revealed that fiber levels exerted no discernable impact on growth performance (average daily feed intake (ADFI), and average daily gain (ADG)) of Er-HL (p > 0.05). Conversely, L-LW exhibited a decrease in ADFI and ADG with increasing fiber levels (p < 0.05). Notably, the apparent total tract digestibility (ATTD) of various fiber components, including neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, TDF and insoluble dietary fiber (IDF), in Er-HL were significantly higher than those in S-LW and L-LW irrespective of diets (p < 0.05). The ATTD of cellulose and hemicellulose in Er-HL significantly decreased with increasing fiber levels (p < 0.05), yet remained statistically indifferent when comparing the 7%-wheat-bran-replaced diet (7% WRB, TDF 16.32%) to the basal diet (TDF 14.07%) (p > 0.05). The cecal microbiota of Er-HL had higher richness estimators (Chao1 and ACE) than those of S-LW and L-LW irrespective of diets (p < 0.01). Breed serves as a pivotal determinant in shaping swine gut microbiota. Thirteen genera were selected as the key bacteria related to high fiber digestibility of Er-HL. Further functional examination of these key genera elucidated an enrichment of pathways pertinent to carbohydrate metabolism in Er-HL samples compared with S-LW and L-LW samples. In summary, Er-HL exhibited high-fiber tolerance both in terms of growth performance and fiber digestibility compared with Large White pigs. Specifically, the ATTD of NDF, ADF, hemicellulose, IDF and TDF were significantly higher in Er-HL compared with L-LW and S-LW, irrespective of diets. Fiber level exerted no discernable impact on growth performance (ADFI, ADG) and the ATTD of fiber (NDF, ADF, IDF and TDF) in Er-HL. The optimum fiber level of the Er-HL was identified as 7% WRB (TDF 16.32%). Thirteen genera were ascertained to significantly contribute to high fiber digestibility of Er-HL, correlating with an enhancement of carbohydrate metabolism pathways.

Abstract
RUNX1T1 (Runt-related transcription factor 1, translocated to 1) plays a wide-ranging and diverse role in cellular development, including hematopoiesis and adipogenesis. However, little is known about the function of RUNX1T1 in the skeletal muscle development. Here, we assessed the impact of RUNX1T1 on the proliferation and myogenic differentiation of goat primary myoblasts (GPMs). It was observed that RUNX1T1 is highly expressed during the early stages of myogenic differentiation and the fetal stage. Moreover, the knockdown of RUNX1T1 promotes the proliferation and inhibits myogenic differentiation and mitochondrial biogenesis of GPMs. RNA sequencing analysis revealed that significantly differentially expressed genes in RUNX1T1 knockdown cells were enriched in the calcium signaling pathway. Additionally, we discovered that RUNX1T1 regulates alternative splicing (AS) events involved in myogenesis. We also show that silencing RUNX1T1 blocked the Ca2+ -CAMK signaling pathway and reduced the expression levels of muscle-specific isoforms of recombinant rho associated coiled coil containing crotein kinase 2 (ROCK2) during myogenic differentiation, partially explaining why RUNX1T1 deficiency leads to the impairment of myotube formation. These findings suggest that RUNX1T1 is a novel regulator of myogenic differentiation that regulates the calcium signaling pathway and AS of ROCK2. Overall, our results highlight the critical role of RUNX1T1 in myogenesis and broaden our understanding of myogenic differentiation.
