Medientyp: E-Artikel Titel: Effect of including sweet potato (Ipomoea batatas Lam) meal in finishing pig diets on growth performance, carcass traits and pork quality Beteiligte: Pietrosemoli, Silvana; Moron‐Fuenmayor, Oneida Elizabeth; Paez, Angel; Villamide, Maria Jesús Erschienen: Wiley, 2016 Erschienen in: Animal Science Journal Sprache: Englisch DOI: 10.1111/asj.12546 ISSN: 1740-0929; 1344-3941 Schlagwörter: General Agricultural and Biological Sciences ; General Medicine Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>The partial replacement of a commercial concentrate at 10‐20% and 15‐30% (the first percentage of each dietary treatment corresponded to weeks 1–3 and the second to weeks 4–7 of the experiment, respectively) by sweet potato meal (SPM; 70% foliage: 30% roots) was evaluated for growth performance, carcass yield, instrumental and sensory pork quality using 36 commercial crossbred pigs (56.8 ± 1.3 kg initial body weight). Three dietary treatments were compared in a randomized complete block design. Most growth, carcass traits and pork quality variables were not affected by the SPM inclusion. Growth performance averaged 868 g/day and feed efficiency 0.24 kg/kg. However, feed intake increased 2.2% (<jats:italic>P</jats:italic> = 0.04) in pigs fed the 10‐20% SPM diets, in a similar order of magnitude as the decrease in dietary energy. Despite an increase in gastrointestinal tract as a percent of hot carcass weight (+14.7%) (<jats:italic>P</jats:italic> = 0.03) with SPM inclusion, carcass yield averaged 69.4%. Conversely, decreases in loin yield (−4.2%) (<jats:italic>P</jats:italic> = 0.05), backfat thickness (−6.0%) (<jats:italic>P</jats:italic> < 0.01) and pork tenderness (−13%) (<jats:italic>P</jats:italic> = 0.02) were observed with 15‐30% SPM inclusion. Results suggest that up to 20% SPM inclusion is a viable feed strategy for finishing pigs, easily replicable in small farm settings. © 2016 Japanese Society of Animal Science</jats:p>
