Five experimental diets were formulated, each containing 30% licorice residue and sweet sorghum (with licorice residue at 0%, 25%, 50%, 75%, or 100% w\/w) and 70% other components. We found that licorice residue level significantly affected pellet hardness, powder content, and volumetric weight (p &lt; 0.05). The L25 group had significantly higher final body weight (FBW) and average daily gain (ADG) than other groups (p &lt; 0.05). In the duodenum, villus height (VH) was improved in L25 (p &lt; 0.05). Ileal VH increased significantly in L0, L25 and L50 (p &lt; 0.05). At the phylum level, Firmicutes were most enriched. At the genus level, Faecousia and SFMI01 abundance increased with higher licorice residue. LEfSe analysis confirmed that varying licorice residue levels influenced cecal microbial composition from phylum to genus. The addition of 25% licorice residue to the diet can improve the growth performance of meat rabbits and improved both intestinal tissue morphology and the cecal microbiota of meat rabbits.<\/jats:p>","DOI":"10.3390\/microorganisms14040868","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T11:38:26Z","timestamp":1776080306000},"page":"868","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Different Levels of Licorice Residue and Sweet Sorghum on Pellet Feed Quality, Intestinal Morphology, Cecal Volatile Fatty Acids, and Microorganisms in Meat Rabbits"],"prefix":"10.3390","volume":"14","author":[{"given":"Jie","family":"Wan","sequence":"first","affiliation":[{"name":"Key Laboratory of Livestock and Grass Resources Utilization Around Tarim, Ministry of Agriculture and Rural Areas (Co-Construction by Ministries and Provinces), Key Laboratory of Tarim Animal Husbandry Science and Technology, College of Animal Science and Technology, Tarim University, Alar 843300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingxin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Livestock and Grass Resources Utilization Around Tarim, Ministry of Agriculture and Rural Areas (Co-Construction by Ministries and Provinces), Key Laboratory of Tarim Animal Husbandry Science and Technology, College of Animal Science and Technology, Tarim University, Alar 843300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qihui","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Livestock and Grass Resources Utilization Around Tarim, Ministry of Agriculture and Rural Areas (Co-Construction by Ministries and Provinces), Key Laboratory of Tarim Animal Husbandry Science and Technology, College of Animal Science and Technology, Tarim University, Alar 843300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Ren","sequence":"additional","affiliation":[{"name":"Key Laboratory of Livestock and Grass Resources Utilization Around Tarim, Ministry of Agriculture and Rural Areas (Co-Construction by Ministries and Provinces), Key Laboratory of Tarim Animal Husbandry Science and Technology, College of Animal Science and Technology, Tarim University, Alar 843300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lianqun","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Livestock and Grass Resources Utilization Around Tarim, Ministry of Agriculture and Rural Areas (Co-Construction by Ministries and Provinces), Key Laboratory of Tarim Animal Husbandry Science and Technology, College of Animal Science and Technology, Tarim University, Alar 843300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chongpeng","family":"Bi","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Northeast Agricultural University, Harbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4022-225X","authenticated-orcid":false,"given":"Sujiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Livestock and Grass Resources Utilization Around Tarim, Ministry of Agriculture and Rural Areas (Co-Construction by Ministries and Provinces), Key Laboratory of Tarim Animal Husbandry Science and Technology, College of Animal Science and Technology, Tarim University, Alar 843300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,12]]},"reference":[{"key":"ref_1","unstructured":"Olaleru, I.F., Busari, I.O., and Solana, O.I.
