| Popis: | Lambs from intensive dairy sheep production systems are sold out either after weaning as milk-fed lambs or after a fattening characterized by high intakes of concentrate feeds (mainly cereals) which can lead to ruminal disorders. Therefore, it is essential to explore different feeding alternatives in order to reach a balance between economic or productive benefits and animal welfare. Twenty weaned male lambs (6–8 weeks age, 14.8 ± 0.16 kg body weight) were allocated randomly to one of two different groups (n = 10 per group) to study the effect of feeding a complete pelleted diet (CPD) in which cereal grains were ground at two different sieve sizes (either 2-mm with 13.5% dry matter (DM) of the particles >1.7 mm or 6-mm with 47.1% DM of particles >1.7 mm) on DM intake, nutrient digestibility, ruminal microbiota and fermentation. Lambs were fed the corresponding CPD ad libitum and slaughtered when they reached 27 kg. DM intake was greater in the lambs fed 2-mm grains than in those fed 6-mm grains (P This work was supported by CSIC (Proyecto Intramural Especial; Project 201540E084) and the Spanish Ministry of Economy and Competitiveness (MINECO; AGL2014-54124-R). Support was also provided by a predoctoral contract (C. Blanco) funded by Junta de Castilla y Leon and the European Social Fund. The Consortium of Mexican Universities (CUMEX) and Autonomous University of Ciudad Juarez provided a grant to E. Jaramillo. |
