Effect of Replacing Soybean Meal with Lupin Seed-based Meal in Chicken Diet on Performance, Carcass Value and Meat Quality

Abstract

The main objective of this experimental study was to determine how diets containing lupin meal affect the performance indicators, carcass value, and chemical composition of breast and thigh muscles in broiler chickens. The diets tested in experimental groups E1 and E2 differed as follows: in group E1, one third of nitrogen-containing substances (NSs) from extracted soybean meal was replaced with NSs from lupin meal; in group E2, two thirds were replaced compared to the control group. The replacement of soybean meal with lupin meal in experimental diets failed to produce any significant effect on the average live weight of chickens on Day 42 of the fattening period compared to the control group. The replacement of soybean meal with lupin meal resulted in decreased average weight of carcass and breast muscles and in decreased yield of breast muscles. Differences between the control group (C) and group E2 were significant (P ≤ 0.01). Chickens in group E2 also showed a significant increase (P ≤ 0.01) in the yield of the heart and stomach compared to the control group. The differences in weight and yield of thigh muscles between the control group and the experimental groups (E1 and E2) were not significantly affected. As far as chemical composition is concerned, chickens receiving the lupin-containing feed showed a significant (P ≤ 0.01) increase in the ash content in breast muscles. On the contrary, in thigh muscles in group E2, the ash content decreased significantly (P ≤ 0.01). The content of calcium showed an increasing trend in both breast and thigh muscles in both experimental groups. In contrast, the content of magnesium in chicken muscles in both experimental groups decreased. These differences were significant (P ≤ 0.01) only in thigh muscles. Our results show that lupin seed is a suitable substitute for NSs contained in soybean extracted meal. It is considered optimal to replace up to one third of NSs contained in soybean meal with lupin seed. Higher inclusion rate of lupin meal in diets may reduce the growth intensity of chickens, particularly the yield of breast muscles. Due to substantial inter-varietal differences, it is necessary to optimize individual nutrients, particularly amino acids when formulating lupin-containing diets. Broiler chickens, weight and yield of organs and muscles, chemical composition of breast and thigh musclesFrom a nutritional point of view, the seed of cultivars of the genus Lupinus is a proteinenriched raw material used as feed or in feeding mixtures intended for the nutrition of practically all species and categories of farm animals. For these reasons, lupin growing areas in Europe are expanding. In the Czech Republic, growing and using lupin is not as common as in the neighbouring countries. Ecologically speaking, lupins are promoted because most lupin varieties are not genetically modified.The use of lupins in diets for poultry was tested by a number of authors, for example by Schams-Schargh et al. (1994). Their experiment examined the effect of sweet lupins in diet...

Effects of Different Amounts of Blue Lupine (L. Angustifolius L.) in The Diets of Heavy-Type Turkeys on Their Growth Rate, Carcass and Meat Qualities

“…No significant differences for the ash content were found in the breast muscles of male and female turkeys and in the thigh muscles of female turkeys. This is in agreement with the findings of Suchy et al (2010) who indicated that the ash content in the thigh muscles of male chickens fed 17.3 to 31.0% lupines was lower, however, than in the breast muscles of the same chickens was significantly higher.…”

“…In our study, the dry matter and protein content data in the female breast muscle, male and female thigh muscles (Table 6, 7,8) indicated that diet supplementation with lupines had not affected the above indicators. This is in agreement with the results of Olver (1987) in the study with chickens fed 40% white lupine (variety 'Buttercup') regarding dry matter difference, Suchy et al (2010) regarding protein content difference (from one third to two thirds white lupine in the feed, variety 'Amiga'), Froidmont et al (2004), who found no difference for the above indicators in thigh muscles (30-58% lupines in the feed) and Sitko & Čermak (1998) who indicated no difference for the protein content in breast and thigh muscles with 20% lupine in the feed. Moreover, no difference for the dry matter and protein content in the breast muscles were reported by Krawzcyk et al (2015) in the study with female turkeys fed 8-24% yellow lupine (variety 'Baryt') and Mikulski et al (2014) in the study with male turkeys fed 6-18% blue lupine (variety 'Sonet').…”

“…This is in agreement with the findings of Witak et al (2006) in the trial with chickens fed 2.5-15% yellow lupine, Suchy et al (2010) and Orda et al (2006) in the trials with chickens fed, respectively, 8.7-31.0% white lupine (variety 'Amiga') and 5-20% yellow lupine (variety 'Juno'). On the contrary, Mikulski et al (2014) indicated that 18% blue lupine (variety 'Sonet') in the diet of male turkeys had resulted in significantly higher content of abdominal fat.…”

Effects of lupin seed supplementation on egg production performance, and qualitative egg traits in laying hens

“…In the present study, we evaluated the effects of lupin diets in replacing soybean meal on egg production and egg quality in laying hens. It is well documented that lupin diets, as an alternative to soybean meal, have positive effects on performance, carcass value, and meat quality in broilers (Suchy et al 2010;Laudadio and Tufarelli 2011b). Diets with different concentrations of lupin seeds influenced the average daily feed intake in the present study.…”

Haematological indicators in hybrid mallard ducks (Anas platyrhynchos) with regard to the use of meal from whole white lupin seeds in their diet

“…Recently, however, the use of home-grown legume seeds is becoming increasingly important as an alternative source to using soybean products, especially in climate areas that are less favourable for the production of soybean (Nalle et al 2012;Kaczmarek et al 2016). In this regard, home-grown white lupin seeds (Lupinus albus) may effectively be used as an important vegetable protein source in feed used for the fattening of various food animals (Straková et al 2006;Suchý et al 2010;Hernández and Roman 2016).…”
