Nutritional Value of Lupine in the Diets for Pigs (a Review)

Abstract

The seeds of sweet lupine cultivars (Lupineus species) have been used with increasing frequency as a source of proteins replacing proteins of animal origin or soybean in feed compounds. The seeds of sweet lupine cultivars contain an average of about 33-40% crude protein in dry matter, the lipid content ranges from 5 to 13%. The profile of amino acids is relatively beneficial, however, with slightly lower content of lysine (1.46%) and methionine (0.22%). The main storage carbohydrates in the seeds are the β-galactans that comprise most of the cell-wall material of the kernel and the cellulose and hemicellulose of the thick seed coats. Lupine seeds contain about 40% non-starch polysaccharides (NSP) and a negligible amount of starch. High coefficient of protein digestibility (> 90%) has been reported in sweet lupine cultivars, but lower digestibility of energy (~ 60%). Lupineus species contain negligible amounts of trypsin inhibitor so they do not require preheating before being used as an ingredient in feeds for monogastric animals. The efficiency of lupine seeds in the diets for pigs is characterized by controversial results of growth and feed conversion under both mechanical treatment and enzyme supplementation. The results of production efficiency obtained at the testing of lupine cultivars (L. albus, L. angustifolius) for pigs were beneficial at supplementation of the lacking nutrients or dehulling. The submitted paper summarizes national as well as foreign knowledge of the nutritive value of cultural lupine seeds, and deals with the possibility increasing nutrition and production efficiency in the diets for pigs.

Characterization and effect of year of harvest on the nutritional properties of three varieties of white lupine (Lupinus albusL.)

“…is partly due to the low level of starch, which is replaced by fat as the main energy source. As expected, lupine seeds showed more dietetically beneficial structural carbohydrates (NDF 242 g kg −1 DM) compared with other leguminous seeds (peas, faba beans, soy beans); this fraction is mainly represented by pectin‐like material . The ME value, estimated from chemical and gas production data, differed slightly between seeds (mean 14.5 ± 0.60 MJ kg −1 DM).…”

It is necessary to underline that, in ME calculation, fat and fiber levels as well as other nutrient availability have a negative influence on microorganism activity in the rumen and consequently on in vitro fermentation.…”

Lupin as a perspective protein plant for animal and human nutrition – a review

“…As regards white lupin of Amiga variety, the authors (Zralý et al 2008;Písaříková and Zralý 2009) found out a fat content of 107.7 g/kg. In Butan variety, the content in a whole or dehulled seed is 79.1 and 102.3 g/kg of dry matter.…”

“…It contains 33-40 % of crude protein and 5-13 % oil. 4,5 In Egypt, the productivity of 1482 ha cultivated with lupine is 2881 tons (19, 439 kg/ha). 6 The productivity of lupine remains low due to physiological, biological and environmental stress factors.…”
