| Durch den Mangel an Futtermitteln ökologischer Herkunft mit hochwertigem Aminosäurenmuster besteht die Gefahr zu geringer Lysingehalte in der Anfangsmastration im Vergleich zu den GfE-Bedarfsnormen, woraus eine zu starke Verfettung des Schlachtkörpers resultieren kann. Daher sollte in einer Untersuchung geklärt werden, ob nach einer Lysin-Unterversorgung in der Anfangsmast nach geeigneter Realimentation in der Endmast ein kompensatorischer Proteinansatz stattfindet. Dazu wurden 96 Mastschweine einer modernen Genetik (48 Kastrate, 48 Sauen) in 4 Gruppen mit unterschiedlich gestalteten Lysin-ME-Quotienten in der Anfangs-/Endmastration (Versuchsgruppe: 0,69/0,69; Negativkontrolle: 0,69/0,59; Positivkontrolle: 0,89/0,69; Kontrolle 0,89/0,59) auf Mastleistung,... |

| Due to a lack of organic feed with a high quality amino acid pattern it is difficult to achieve the required Lysine-Metabolisable-Energy-ratio in organic grower diets with the danger of reduced value creation. Hence, the present study should investigate whether a moderate oversupply of lysine in the finisher diet after a marginal lysine supply in the grower diet results in compensatory growth. 96 fattening pigs were divided into four groups characterised by different Lysine-ME-ratios in the grower/finisher diets (Experimental Group: 0.69/0.69; Negative Control Group: 0.69/0.59; Positive Control Group: 0.89/0.69; Regular Control Group: 0.89/0.59). Performance and carcass quality were recorded. The economic success was calculated under varying feed cost... |
