This study evaluated the effects of dietary FA on meat quality and muscle development in Shaziling pigs. A total of 108 pigs (30 kg \u00b1 0.71 kg) were selected and randomly assigned to three groups, with six replicates per group and six pigs per replicate. Pigs were fed a corn\u2013soybean meal basal diet supplemented with 0 mg\/kg, 250 mg\/kg, or 500 mg\/kg of FA for 120 days. Results showed that FA reduced fat percentage, increased lean meat percentage and loin-eye area, enhanced redness and pH, and elevated muscle crude protein content. It also increased muscle fiber diameter and improved antioxidant enzyme activities (p &lt; 0.05). The FA increased the levels of capric acid and methionine in the muscle, while reducing the content of stearic acid (p &lt; 0.05). Furthermore, analysis of muscle development-related genes showed that FA upregulated the expression of PI3K, AKT1, mTOR and downregulated the expression of FOXO1 and MSTN in the muscle (p &lt; 0.05). Analysis of muscle fiber type and glucose metabolism-related genes revealed that FA upregulated the expression of PGC-1\u03b1, MYH IIa, MYH I, HK2, and PFK and downregulated the expression of PKM and MYH IIX in the muscle (p &lt; 0.05). In conclusion, FA improves muscle development and meat quality in Shaziling pigs, possibly through modulation of genes associated with PI3K\/AKT\/mTOR signaling, enhancement of antioxidant capacity, and regulation of muscle fiber type and glucose metabolism.<\/jats:p>","DOI":"10.3390\/foods15122111","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T01:52:08Z","timestamp":1781229128000},"page":"2111","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Ferulic Acid on Meat Quality, Carcass Traits, Muscle Fiber Types, and Muscle Development in Shaziling Pigs"],"prefix":"10.3390","volume":"15","author":[{"given":"Xiwen","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuning","family":"Jin","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenghuan","family":"Hu","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Luo","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulian","family":"Li","sequence":"additional","affiliation":[{"name":"Xiangtan Livestock Breeding Station, Xiangtan 411100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianhua","family":"He","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yurong","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1007\/s44154-024-00209-2","article-title":"Phytogenics in swine nutrition and their effects on growth performance, nutrient utilization, gut health, and meat quality: A review","volume":"5","author":"Madesh","year":"2025","journal-title":"Stress Biol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"4600","DOI":"10.1002\/jsfa.70539","article-title":"Ferulic acid improves growth performance and lipid metabolism and bile acid level partially by activating the PPAR and CYP7A1 pathways in broilers","volume":"106","author":"Long","year":"2026","journal-title":"J.
