This study aimed to determine the effects of increased energy and amino acids (AA) intake during gestation on reproductive performance, milk composition, blood parameters, placental nutrient transport and antioxidant capacity of high-parity sows. A total of 72 Landrace × Yorkshire sows (seventh to ninth parity) were randomly assigned to dietary treatments consisting of combinations of 2 energy levels and 2 AA levels in a 2 × 2 factorial design. Blood and milk samples and placentas from sows were collected to measure biochemistry parameters, milk composition, antioxidant indexes, and indicators related to nutrient transport. The results showed that sows fed high energy reduced the number of live born piglets (<i>p</i> < 0.05), increased the birth weight of piglets (<i>p</i> < 0.05).

OA most often results from developmental orthopedic problems such as hip dysplasia, elbow dysplasia, and patellar luxation and from injuries to the cranial cruciate ligament. Several management approaches have been proposed to manage OA, including steps to modulate growth, physical activity, and exercise, nutrition and nutritional supplementation, medications, physical rehabilitation, and surgical procedures. This article is the first in a series of articles that propose steps for practical OA management in dogs at various life stages. The review presented here focuses on growing dogs. The text describes the early pathophysiology and diagnosis of OA. The physical, nutritional, analgesic, and surgical management options of OA in growing dogs are presented. The application of these management options is described for three dogs. The overall approach to the management of OA in growing dogs is discussed.</p>","PeriodicalId":12772,"journal":{"name":"Frontiers in Veterinary Science","volume":"12 ","pages":"1565922"},"PeriodicalIF":2.6,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12067799/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
