Effects of Different Dietary Levels of Blue Lupine (Lupinus angustifolius) Seed Meal With or Without Probiotics on the Performance, Carcass Criteria, Immune Organs, and Gut Morphology of Broiler Chickens

Abstract

This study aimed to investigate the effects of different dietary levels of blue lupine (Lupinus angustifolius) seed meal with or without probiotics (Bacillus subtilis) in broiler diets on the growth performance, carcass characteristics, internal and immune organs, and gut morphology. Three experimental diets containing 0, 20, and 30% of blue lupine, with or without probiotics, were formulated and fed to 144 day (d)-old Ross 308 broiler chickens. Overall, chicks fed blue lupine meal diets, especially at the 30% rate, showed improved growth, feed performance parameters, and carcass characteristics in comparison to chicks fed a soybean meal-based diet. For example, a 30% blue lupine diet resulted in a significant increase in the duodenum length percentage of 35 d-old broilers; the addition of probiotics had no-effects on the dressing, thigh, and leg percentages of 21-and 35 d-old broilers and the drumstick and leg percentages of 35 d-old broilers. In conclusion, a 30% blue lupine seed diet with the addition of probiotics could provide a cheap source of protein without negative effects on the growth performance, carcass characteristics, immune organs and gut morphology of broilers.

Beneficial effects of substituting soybean meal for white lupin (Lupinus albus, cv. Zulika) meal on the biochemical blood parameters of laying hens

“…Results of this experimental study show that the tested diets, affected some of the indicators in the metabolic blood profile of the hens during long-term feeding. As mentioned by Jeroch et al (2016) and Al-Sagan et al (2020), lupin seeds are a great benefit, especially in poultry nutrition, thanks to their unique amino acid composition, characterised by a high content of arginine, which is for poultry one of the essential amino acids. Using blue lupin (Lupinus angustifolius) as the main protein source in the diets for laying hens and its beneficial effect on the weight gain, size and number of eggs (yolk colour included) were observed by Lee et al (2016).…”

“…Finding protein feeds capable to completely or partially replace soya products (soybean meal is one of the priorities of European agriculture) became very important after the ban on feeding meat and bone meal feeds to livestock animals. The high price of imported soya commodities, but also the issue of genetically modified crops (which include most varieties of soybean, de Vos and Swanenburg 2018), are heightening pressure on the production of other protein feeds (Al-Harthi et al 2018;Al-Sagan et al 2020) and the challenging was thus increase after COVID-19 negative impacts of feed chain and agriculture sector (Hafez and Attia 2020). From this point of view, legumes, in which cultivated species of lupins are included (genus Lupinus), may be considered as potential protein crops (Al-Sagan et al 2020).…”

From this point of view, legumes, in which cultivated species of lupins are included (genus Lupinus), may be considered as potential protein crops (Al-Sagan et al 2020). White lupin varieties contain in fact comparable amounts of crude protein as soybeans as documented by Martinez-Villaluenga et al (2006).…”

“…For these reasons, the seeds of cultivated white lupin varieties are a subject of great interest as an alternative source of dietary protein in feed mixtures for animals, e.g. for fattening pigs (Zral y et al 2008;Kasprowicz-Potocka et al 2016) or for rabbits (Volek et al 2018) and broiler chickens (Al-Sagan et al 2020). Lupin seeds find wide range of utilisation in feed mixtures for poultry nutrition (Jeroch et al 2016), primarily in the fattening of broiler chickens (Suchy et al 2010;Olkowski 2018), or rearing of laying hens (Rutkowski et al 2017).…”

ZnO and TiO2 nanoparticles alter the ability of Bacillus subtilis to fight against a stress

“…The natural biotope of Bacillus subtilis is the upper layer of soil, but it has also been found in the gut microbiome. It is also used to feed broiler chickens or fish to improve growth performance or immunology responses in absence of classical antibiotics [ 21 – 23 ]. It is also mixed with other bacteria to prepare probiotics for humans [ 24 ].…”
