Common names 

Yellow lupin

Species 
Distribution 

Lupins (Lupinus spp.) are broadly distributed throughout the world. There are two geographically separate groups: new World species and Old Word species among which 4 are cultivated, one in from the New World and the 3 others from the Old World. All of them being smooth seeded. Lupins occupy almost all kinds of habitats from sea level to altitudes up to 4000 m (Wolko et al., 2010).

Environmental impact 

N-fixing legume and sustainable P management

Lupins are N-fixing legumes that are reported to fix 300-400 kg N /ha in Europe and Australia (Jansen, 2006). Lupins can provide benefit to the following crop (Pgro, 2014). In organic crops, lupins were demonstrated to result in a 0.5 t/ha response in rye grown following yellow lupins compared to following spring beans.

Lupins are valuable legumes for sustainable P management : in soils depleted in available P, lupin plants form specialized cluster root structures and/or release P-mobilizing carboxylates that free it from insoluble forms (Lambers et al., 2012).

Soil improver

Thanks to its deep taproot lupin plants improve soil texture and drainage(Jansen, 2006). 

Nutritional aspects
Potential constraints 

Oligosaccharides

Lupin seeds (Lupinus spp.) are known to contain significant levels  (from 7 to 20%) of oligosaccharides of the raffinose family (Saini, 1989). Inthe seeds of blue or yellow lupin species, alpha-galactosides levels can reach up to 20% (Saini, 1989). Oligosaccharide level may depend on variety but also on conditions of cultivation and harvest (Pisarikova et al., 2009).

Rabbits 

Very few information is available in the international literature on the utilisation of yellow lupin seed in rabbit feeding. Only one French study on the incorporation of Lupinus luteus and L. albus seeds introduced at 20% of the diet, in comparison with a soybean meal control diet resulted in similar performances (growth rate and feed efficiency) in growing rabbit for all experimental groups (Lebas, 1986). As a consequence of these results and because Lupinus luteus seeds can also be used with good technical results to feed various farm animals such as broiler chickens (Roth-Maier et al., 2003), young turkeys (Zdunczyk et al., 2016), weaner pigs (Kim et al., 2008) or reproducing ewes (Somchit-Assavacheep et al., 2013), these seeds may be considered as a raw material usable in rabbit feeding.

The theoretical main nutritional characteristics for rabbits are close to those of white lupin: 35-38% crude protein deficient in sulphur-containing amino acids, but with a higher SAA content than white lupin (Petterson, 2000), a calculated digestible energy content of about 14.5 MJ/kg DM (Lebas, 2016) and a content of lipids of 5 to 6% with 7-10% of alpha-linolenic acid in the total fatty acids (Chiofalo et al., 2012).
