“…32 The notable protein content of MD lupin seeds has nutritional significance, since moderate intake of these grains will greatly increase the total dietary protein intake. Hence, its utilisation as an alternative protein source in poultry formulation will reduce over-dependence on conventional plant protein such as soybean meal.…”

“…Lupin kernels were evaluated in the latter study, whereas seeds with hulls were used in this study and the dilution effect of hulls may explain, at least partly, the observed discrepancy. The proportion of hulls in the lupin seeds can be as high as 0.32, and Nalle et al (2010b) reported that dehulling of Australian sweet lupin seeds resulted in marked reductions in NSP contents and improved AME values.…”

“…It is concluded that, when diets are balanced in terms of metabolisable energy and digestible amino acids, white lupins can be included at a level of 200 g/kg in broiler starter diets, with no detrimental effect on performance. Further studies are warranted to investigate the possibility of higher levels of inclusion of white lupins in broiler diets through the removal of hulls (Nalle et al, 2010b) and/or the use of NSP-degrading enzymes.…”

Two experiments were conducted to evaluate the nutritional value of three cultivars (Promore, Kiev mutant and Ultra) of white lupins (Lupinus albus L.) for broilers. In experiment 1, the apparent metabolisable energy (AME) and ileal amino acid digestibility coefficients of the three cultivars were determined. The cultivar effects were significant (P , 0.05) for AME, but the ileal amino acid digestibility coefficients were similar (P . 0.05) between cultivars. The AME value of Ultra cultivar was lower (P , 0.05) than those of Promore and Kiev mutant cultivars. In Experiment 2, using the AME and ileal digestible amino acid values determined in Experiment 1, diets containing 200 g/kg of lupin were formulated and the effects of feeding these diets on performance, digestive tract development and excreta quality of broiler starters were investigated. Weight gain, feed intake and feed per gain of broilers fed diets containing white lupins were similar (P . 0.05) to those fed the maize-soybean meal diet. The performance of birds fed diets containing different cultivars of white lupins was similar (P . 0.05). Several digestive tract parameters were influenced by the dietary inclusion of white lupins. In particular, the relative liver weight and the relative empty weights of small intestine and caeca in birds fed diets containing white lupins were higher (P , 0.05) than those fed the maize-soybean meal diet. No differences (P . 0.05) were observed in the excreta quality scores between the birds fed the maize-soybean meal diet and those fed diets containing white lupins.

“…Lupin by-products are generated during feed production for pigs and poultry, as de-hulling lupin seeds is important for these species in terms of increasing their nutritive value (Mieczkowska et al, 2005;Písaříková and Zralý, 2009;Nalle et al, 2010). Volek et al (2013) showed that white lupin hulls seem to be suitable for use in rabbit diets.…”

White lupin bran and its effects on the growth performance, carcass characteristics and digestibility of nutrients in fattening rabbits

The purpose of the present study was to evaluate the effects of including white lupin bran (WLB) in a fattening rabbit diet on growth, carcass traits and nutrient digestibility. The C diet (control) based on alfalfa meal, whereas the WLB 5 and WLB 15 diets were based on white lupin bran (crude protein 152 g/kg, neutral detergent fibre 524 g/kg as-fed basis). The WLB 5 diet contained 50 g of white lupin bran/kg instead of 50 g of alfalfa meal/kg, whereas the WLB 15 diet contained 150 g of white lupin bran/kg, 5 g of soybean meal/kg and 10 g of sugar beet pulp/kg instead of 165 g of alfalfa meal/kg. The diets had similar digestible protein/digestible energy ratios. A total of 150 Hyplus rabbits between the ages of 30 to 73 d were randomly allocated into one of 3 groups and fed one of the 3 experimental diets. Additionally, another 30 Hyplus rabbits (10 per dietary treatment) at the age of 30 d were selected to determine coefficients of total tract apparent digestibility (CTTAD) of diets between 63 and 67 d of age. The dietary treatments did not affect the final live weight of rabbits (mean=2969 g). There was a higher feed intake (+30 g/d; P<0.001) in both groups of rabbits fed the WLB 5 and WLB 15 diets compared to rabbits fed the C diet, which led to impaired feed conversion ratios (P<0.001). Sanitary risk index was not affected by dietary treatment. The rabbits fed the WLB 15 diet exhibited a higher drip loss percentage (+0.65%; P<0.001) than the rabbits fed the other diets, as well as a lower dressing-out percentage (by 1.6%; P=0.024). The CTTAD of the lignocellulose fraction (acid detergent fibre) was significantly higher in rabbits fed the WLB 5 and WLB 15 diets than in those fed the C diet. White lupin bran may be used as a dietary fibrous by-product without significant impairment of the nutritive value of the diet. This lupin by-product can be included in diets for fattening rabbits up to 15% as a partial replacement of alfalfa meal.
