title: Effects of feeding rumen-protected sunflower seed and meal protein on feed intake, diet digestibility, ruminal, cecal fermentation, and growth performance of lambs creator: Haro Haro, Andrés Norberto creator: Gonzalez Cano, Javier creator: Evan, T. de creator: Fuente, Jesús de la creator: Carro Travieso, Maria Dolores subject: Agriculture subject: Veterinary description: The objective of this study was to analyze the efficacy of a treatment (MAH) of sunflowerseed (SS) and meal (SM) with a malic acid solution (1 M; 400 mL/kg) and heating (150◦C, 2 h) toprotect protein against rumen degradation and to improve the growth of lambs. Two homogeneousgroups of 12 Lacaune lambs each (14.2±0.35 kg body weight) were fed either a concentrate includinguntreated SS and SM or a concentrate with MAH-treated SS and SM. Lambs were fed concentrate andbarley straw ad libitum for 40 days (about 26 kg body weight); feed intake and growth of lambs wererecorded; blood samples were taken on days 0, 20, and the slaughter day for analysis of urea-N andamino acid-N; diet digestibility was determined; and ruminal and cecal samples were collected afterslaughter. Thein vitroincubation of both concentrates with sheep ruminal fluid for 12 h showed thatthe MAH-treatment tended to reduce NH3-N concentrations and increased propionate production.However, there were no differences (p>0.05) between groups in any of the tested variables in thein vivo trial. publisher: E.T.S. de Ingeniería Agronómica, Alimentaria y de Biosistemas (UPM) rights: https://creativecommons.org/licenses/by-nc-nd/3.0/es/ date: 2019-07 type: info:eu-repo/semantics/article type: Article source: Animals, ISSN 2076-2615, 2019-07, Vol. 9, No. 7 type: PeerReviewed format: application/pdf language: eng relation: http://www.mdpi.com/journal/animals relation: info:eu-repo/grantAgreement/MINECO//AGL2012-3106 relation: info:eu-repo/grantAgreement/CAM//S2013%20FABI-2913 rights: info:eu-repo/semantics/openAccess relation: info:eu-repo/semantics/altIdentifier/doi/10.3390/ani9070415 identifier: https://oa.upm.es/63546/
