“…Alkaloid content in blue lupin seeds has ranged from 0.1 up to 2.6 g kg -1 DM (Gdala et al 1996, Christiansen et al 1997, Wasilewko and Buraczewska 1999. Although alkaloids were not analysed in this study, they could be a possible reason for slightly decreased feed consumption in pigs fed high lupin diets.…”

“…Although alkaloids were not analysed in this study, they could be a possible reason for slightly decreased feed consumption in pigs fed high lupin diets. Alkaloid content of blue lupin seeds is influenced by growing conditions (Christiansen et al 1997), and the feed intake of pigs decreases when the alkaloid content of the diet exceeds 0.2 g kg -1 feed (Godfrey et al 1985). Lupin seeds also contain large amounts of α-galactoside oligosaccharides, which cannot be hydrolysed in the small intestine due to the absence of the appropriate enzyme.…”

In 2000, EU regulations for organic animal production set new guidelines for organic pig feeding requiring that this be based on mainly home-grown organic feedstuffs. Doubts were however raised whether these feeding regimes can maintain good growth performance and carcass quality of pigs. Three experiments were carried out to study different organic feeding regimes in weaned piglets and fattening pigs. In Experiment 1, we evaluated the use of peas and faba beans (0, 120, or 240 g kg -1 ) in diets for weaned piglets. Piglets fed pea diets performed as well as those fed the control diet, whereas the highest faba bean level resulted in reduced feed intake and growth performance. In Experiment 2, we studied the replacement (0, 33, or 67%) of rapeseed cake with blue lupins in fattening pig diets. The dietary lupin level had a quadratic effect on the weight gain of growing pigs, the best performance being observed at the 33% replacement level. However, dietary lupin level did not influence weight gain during the finishing period and total fattening. Back fat became softer with increasing dietary lupin levels. In Experiment 3, different protein supplements were compared in organic diets from weaning to slaughter. In two-phase feeding, the best performance was observed when whey protein was used as the protein supplement, followed by soya bean cake + whey protein and rapeseed cake + fish meal. The effects of a one-phase organic feeding regime with coldpressed rapeseed cake + whey protein did not differ from those of the two-phase organic feeding regimes. Fattening pigs fed organic diets required from two to seven days longer to reach slaughter weight than those fed conventional diets. Pigs fed organic diets had fatter carcasses, but the eating quality of organic pork did not differ from that of pork from pigs fed conventional diets. Feed costs and the circulation rate of pigs, weaners in particular, were greater and carcass prices lower in the organic feeding regimes than in the conventional ones.

“…Poppy (Papaver somniferum) produced a higher level of the alkaloids under drought conditions (Szabó et al 2003). The alkaloid content was also affected by drought treatment applied on different growth stages of the three narrow-leafed lupin (Lupinus angustifolius) genotypes (Christiansen et al 1997). …”

Influence of abiotic stresses on plant proteome and metabolome changes

et al. 2013

Plant responses to abiotic stresses are very complex phenomena with individual characteristics for various species. Abiotic stresses (e.g. drought, salinity, flooding, cold, heat, UV radiation, heavy metals, etc.) strongly affect plant growth and development. It is estimated that they are the cause of more than 50 % of crop yield losses. Abiotic stresses are known to activate a multigene response resulting in the changes in various proteins and primary and secondary metabolite accumulation. Therefore, proteomic and metabolomic approaches are becoming very important and powerful tools used in studying plants' reaction to various stimuli. Precise analysis of proteome and metabolome is essential for understanding the fundamentals of stress physiology and biochemistry. In this review, we focus on recent reports concerned to the influence of abiotic stresses on changes in the level of different protein groups and metabolite classes. Basic information about physicochemical methods applied to qualitative and quantitative analyses of biopolymers and natural products is also briefly presented.

“…For example, a high level of glycoalkaloid content resulting in bitterness is found in potatoes grown in extremely frigid and arid conditions (Johns, 1990). The effect of drought stress on seed bitterness was also found (Christiansen, Jornsgard, Buskov, & Olsen, 1997). Therefore, tolerating bitter taste is adaptive to a harsh environment that reduces sweet-tasting and increases bitter-tasting vegetation.…”
