Lupin as primary protein source in young broiler chicken diets: Effect of enzymes preparations catalyzing degradation of non-starch polysaccharides or phytates

Abstract

This work examined the effects of three enzyme preparations (A,B,C) directed towards degradation of Non Starch Polysaccharides (NSP) and one targeting phytates (D) on performance traits in broilers fed maize meal basal diets containing 400 g/kg of yellow lupine seeds (LM). A soybean meal (SBM) based diet served as a reference control. Growth rate, coefficients of total tract apparent digestibility (CTTAD) of organic matter, protein and energy, as well as morphometric measurements of selected sections of gastrointestinal tract (GIT) were determined. In comparison to chickens fed the SBM diet, chickens fed the LM diet consumed less feed, had considerably lower body weight gain, as well as lower CTTAD of measured nutrients and energy. Also the GIT relative weight and length were increased within the group fed the LM diet. Addition of each NSP degrading enzymes (A,B,C) to the LM diet increased feed intake and decreased size of GIT organs (all p \ 0.05). Addition of enzymes A or B increased (p \ 0.05) growth rate of chicks, whereas only enzyme B increased fed efficiency (p \ 0.05) and tended to slightly improve CTTAD of nutrients. The addition of enzyme D did not have any effect on feed intake, growth rate or CTTAD. This study indicates that a diet containing high levels of LM is detrimental to feed intake and condition of the digestive tract of young broilers, and thus affects their performance. However, when the LM diet is supplemented with suitable enzyme preparations, performance parameters are not different from those obtained with SBM.

The effect of addition of yellow lupin seeds (<i>Lupinus luteus</i> L.) to laying hen diets on performance and egg quality parameters

“…In comparison to many publications presenting the results of the use of yellow lupin, pea, faba beans in animal nutrition (e.g., Olkowski et al, 2005;Olkowski, 2011;Kocher et al, 2000;Kaczmarek et al, 2014Kaczmarek et al, , 2015Hejdysz et al, 2015Hejdysz et al, , 2016Rutkowski et al, 2016), studies concerning the inclusion of lupin seeds into laying hen diets are not so common (Watkins and Mirosh, 1987;Hughes and Kocher, 1998;Mierlita, 2013;Krawczyk et al, 2015;Rutkowski et al, 2016). The inclusion of 25% yellow lupin seeds into diet caused a decrease in the laying rate of hens as compared to the effects of control diet and treatments with 10 and 20% lupin addition.…”

Feeding broiler chickens with practical diets containing lupin seeds (<i>L. angustifolius</i> or <i>L. luteus</i>): effects of incorporation level and mannanase supplementation on growth performance, digesta viscosity, microbial fermentation and gut morphology

“…During the following 3 weeks, the BWG in groups fed 25% yellow lupin was lower than in the control group by 5% due to 8% lower feed intake, while the negative effects in groups fed 15% yellow lupin and both levels of narrow-leafed lupin were negligible. In some studies, inclusions of 5%-20% of lupin seed showed little negative impact on growth performance (Roth-Maier and Paulicks, 2003;Orda et al, 2006), while inclusions of 35% or 40% lupin seeds between days 1-21 of life generally decreased performance (Rubio et al, 2003;Steenfeldt et al, 2003;Olkowski et al, 2005;Olkowski, 2011). Sometimes results were even more adverse.…”

“…Supplementation of the diets with feed enzymes exhibiting pectinase, α-galactosidase, arabinoxylanase and β-glucanase activity improved dietary AME value and reduced excreta moisture at the lower level of inclusion, but increased the soluble NSP content of digesta and ileal viscosity at the higher level of inclusion. In some trials, a slight improvement of performance in chickens fed diets with 40% yellow lupin was reported due to enzyme supplementation (Rubio et al, 2003;Olkowski et al, 2010;Olkowski, 2011), while at lower levels of lupin inclusion the enzyme effects were small (Steenfeldt et al, 2003) or insignificant (Orda et al, 2006).…”

Effect of lupin (Lupinus angustifolius) as a soybean meal replacement on the performance, meat quality, and blood parameters of broilers

“…Olkowski et al (2001) reported that when various forms of LP (raw, dehulled, and autoclaved) comprised up to 350 g/kg of a broiler diet (as a substitute for SBM), their supplementation reduced WG and feed efficiency. Olkowski (2011) reported that the reason for reduced WG of birds fed a diet supplemented with LP may be due to the high NSPs in the LP. The reduced WG possibly appear to be alleviated by addition of enzyme (cellulase, pectinase, and β-xylanase) with activity towards degrading NSP in the diet.…”
