The energy value of Lupinus angustifolius and Lupinus albus for growing pigs

摘要: Ninety male crossbred pigs were allocated at 30 kg live weight to a 6 5 factorial experiment involving six diets and five levels of feeding where average daily intakes 1.11, 1.36, 1.67, 1.90 ad libitum between 60 weight. The control diet contained predominantly animal protein sources, another four 350 g/kg either kernels or seeds L. angustifolius cv. Gungurru albus Kiev while the remaining peas. All formulated contain 15.3 MJ DE/kg 0.7 g available lysine/MJ DE ensure that dietary was adequate. Six estimates digestibility each source determined by total faecal collection method. digestible energy contents (SE) seed kernel, kernel peas 15.81 (0.18), 16.85 (0.76), 16.84 (0.34), 17.70 (0.47) 14.98 (0.15) MJ/kg air dry, respectively. killed dressing percentage given 2.6 4.7 units lower than mean other diets. major factors contributing this reduction in when lupins offered gut fill differences intestinal relative value sources assessed comparing relationship rates deposition empty body intake for response similar both thus data consolidated types lupins. respective linear relationships deposited (E, MJ/day)
