However, the behavioral and neurophysiological effects of prolonged use of this intervention during critical periods of postnatal oral skill development have not been systematically examined, although substantial anecdotal evidence suggests that it negatively impacts downstream feeding motor and coordination skills, possibly due to immature sensorimotor development. Using an established animal model for infant and juvenile feeding physiology, we leverage X\u2010ray reconstruction of moving morphology to compare feeding behavior and kinematics between 12\u2010week\u2010old pigs reared on solid chow (control) and an age\u2010 and sex\u2010matched cohort raised on the same chow softened to a liquid. When feeding on two novel foods, almond and apple, maintenance on a soft diet decreases gape cycle duration, resulting in a higher chewing frequency. When feeding on almonds, pigs in this group spent less time ingesting foods compared to controls, and chewing cycles were characterized by less jaw rotation about a dorsoventral axis (yaw) necessary for food reduction. There was also a reduced tendency to alternate chewing side with every chew during almond chewing, a behavioral pattern typical of pigs. These more pronounced impacts on behavior and kinematics during feeding on almonds, a tougher and stiffer food than apples, suggest that food properties mediate the behavioral and physiological impacts of early texture modification\u00a0and that the ability to adapt to different food properties may be underdeveloped. In contrast, the limited effects of food texture modification on apple chewing indicate that such intervention\/treatment does not alter feeding behavior of less challenging foods. Observed differences cannot be attributed to morphology because texture modification over the treatment period had limited impact on craniodental growth. Short\u2010term impacts of soft\u2010texture modification during postweaning development on feeding dynamics should be considered as potential negative outcomes of this treatment strategy.<\/jats:p>","DOI":"10.1002\/jmor.21696","type":"journal-article","created":{"date-parts":[[2024,4,19]],"date-time":"2024-04-19T11:49:31Z","timestamp":1713527371000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Prolonged use of a soft diet during early growth and development alters feeding behavior and chewing kinematics in a young animal model"],"prefix":"10.1002","volume":"285","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8638-9779","authenticated-orcid":false,"given":"St\u00e9phane J.","family":"Montuelle","sequence":"first","affiliation":[{"name":"Department of Biomedical Sciences Ohio University Heritage College of Osteopathic Medicine  Warrensville Heights Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4167-678X","authenticated-orcid":false,"given":"Susan H.","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences Ohio University Heritage College of Osteopathic Medicine  Athens Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,4,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/gimo17"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ddrr.17"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/jez.589"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1601-6343.2010.01483.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-016-9758-y"},{"issue":"2","key":"e_1_2_7_7_1","first-page":"96","article-title":"Dietary consistency and craniofacial development related to masticatory function in minipigs","volume":"17","author":"Ciochon R.
