Abstract
Auf der Grundlage einer Analyse von Energieumsatzmessungen an ausgewachsenen Schweinen bei Verfütterung von 92 Rationen sehr heterogener Nährstoffzusammensetzung werden folgende Vorhersagegleichungen für Brutto‐(y l), verdauliche (y 2) und umsetzbare Energie (y 3) sowie für die Energieansatzwirkung von Rationen (y) (kJ) mitgeteilt:
y 1 = 23,6z 1 + 39,8z 2 + 17,3z 3 + 16,0z 4 + 18,9z 5
y 2 = 23,6x 1 + 39,8x 2 + 17,3x 3 + 16,0x 4 + 17,2x5
y 3 = 20,5x 1, + 39,8x 2 + 17,3x 3 + 16,0x 4 + 17,0x 5
y = 11,0x 1 + 34,0x 2 + 12,7x 3 + 11,6x 4 + 5,0x 7 + (12,0–0,14(80‐x 6))(x 5‐x 7)
z 1 = Rohprotein (g) x 1 = verdl. Rohprotein (g)
z 2 = Rohfett (g) x 2 = verdl. Rohfett (g)
z 3 = Stärke (g) x 3 = verdl. Stärke (g)
z 4 = Zucker (g) x 4 = verdl. Zucker (g)
z 5 = N‐freie Reststoffe (g) x 5 = verdl. N‐freie Reststoffe (g)
x 6 = Verdaulichkeit der Energie der Ration (%) (x 6 ≤ 80)
x 7 = verdl. Pektin (g)
On the basis of an analysis of energy metabolism measurements on adult pigs, fed on 92 rations with very heterogeneous nutrient composition, the following prediction equations for gross energy (y 1), digestible (y 2) and metabolizable energy (y 3) as well as for energy deposition effect of rations (y) (kJ) are presented:
y 1 = 23.6z 1 + 39.8z 2 + 17.3z 3 + 16.0z 4 + 18.9z 5
y 2 = 23.6x 1 + 39.8x 2 + 17.3x 3 + 16.0x 4 + 17.2x5
y 3 = 20.5x 1, + 39.8x 2 + 17.3x 3 + 16.0x 4 + 17.0x 5
y = 11.0x 1 + 34.0x 2 + 12.7x 3 + 11.6x 4 + 5.0x 7 + (12.0–0.14(80‐x 6))(x 5‐x 7)
z 1 = Crude protein, g x 1 = Digest. crude protein, g
z 2 = Crude fat, g x 2 = Digest. crude fat, g
z 3 = Starch, g x 3 = Digest. starch, g
z 4 = Starch, g x 4 = Digest. starch, g
z 5 = Nitrogen free residuals, g x 5 = Digest. Nitrogen free residuals, g
x 6 = Digestibility of energy of rations, % (∗6 =s 80)
x 7 = Digest. pectin, g
