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. date_type: published date: 2019-07 publication: Animals volume: 9 number: 7 pagerange: 415-415 id_number: 10.3390/ani9070415 institution: Agronomica department: Produccion_agraria_2014 refereed: TRUE issn: 2076-2615 official_url: http://www.mdpi.com/journal/animals comprojects_type: MINECO comprojects_type: CM comprojects_code: AGL2012-3106 comprojects_code: S2013/ABI-2913 comprojects_acronym: MEDGAN comprojects_title: Tecnologías de manejo, nutrición y genética para optimizar la producción de alimentos de origen animal característicos de la dieta mediterránea citation: Haro Haro, Andrés Norberto and Gonzalez Cano, Javier and Evan, T. de and Fuente, Jesús de la and Carro Travieso, Maria Dolores (2019).
