Live and internal organ weights of male growing pigs fed low protein and low energy diets supplemented with multi-enzyme

Organ characteristics of male growing male pigs fed low crude protein and low energy diets supplemented with multi-enzyme were determined using 36 hybrid (Landrace x Large white) male pigs of 8-10 weeks old. Two metabolizable energy (3000 and 2600 Kcal ME/kg) and three crude protein levels (14, 16 and 18 % CP) were used to formulate six dietary treatments; T1: control (3000 Kcal ME/kg; 18 % CP), T2 (3000 Kcal ME/Kg; 16 % CP), T3 (3000 Kcal ME/kg; 14 % CP), T4 (2600 Kcal ME/kg; 18 % CP), T5 (2600 Kcal ME/kg; 16 % CP) and T6 (2600 Kcal ME/kg; 14 % CP). The enzyme was added to all the treatments at 1g/kg diet except the control. The treatments were replicated three times with two pigs per replicate. The experiment was a 2 x 3 factorial. The pigs were starved for 12 hours but allowed access to drinking water, stunned and bled completely. It was cut open though the thorax region along the underline to the abdomen, exposing the entire internal organs and GIT contents. The heart, lungs, liver, kidneys, spleen and other internal organs were examined, carefully removed and weighed with a sensitive electronic kitchen scale, model SF-400. Higher (P
