Replacement of soya in pig diets with white lupine cv. Butan

Abstract

ABSTRACT:The purpose of the present study was to evaluate the effect of soya replacement (50 or 100%) with whole (WL) or dehulled seeds (DL) of white lupine cv. Butan in the diets for market pigs. The experiment was performed on 50 pigs in equal numbers of barrows and gilts with the initial mean body weight (BW) of 18.3 ± 2.1 kg, fed isonitrogenous and isoenergetic diets for 100 days. In the experimental starter pigs (18 to 35 kg BW), the mean daily body weight gain (BWG) was 0.61 to 0.64 kg and was insignificantly lower by 1.5 to 6.2% in comparison with the pigs fed the control soya diet (SBM). The diet intake was also lower by 5.4 to 6.8% and could result from a higher content of crude fibre. In the grower and finisher diets, no side effect of high lupine levels on the feed intake was evident. The intake of DL diets was higher in comparison with the soya diet. The feed efficiency of the finisher diets was insignificantly higher (P > 0.05) for experimental diets (WL 50, WL 100, DL 100) in contrast to the control diet. The differences among diets containing WL or DL seeds were insignificant. During the experiment, no adverse effect of lupine on the health of pigs was observed and no significant differences in the parameters of market pig meat, nutrition quality of meat and sensory analysis were detected. The inclusion of lupine in diets resulted in a significantly lower n-6/n-3 ratio of polyunsaturated fatty acids (P < 0.01) in meat lipids (5.15 to 5.33) in comparison with soya (8.75). It follows from the obtained results that the tested lupine variety seeds are a source of high-quality protein that can be an alternative to soya in the diets for market pigs.

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

“…The highest level of amino acids within the crude protein (AA -97.7 g/16 g N) was in white lupine characterised by a higher essential amino acid index (EAAI) (about 85%) as well as chemical score (CS) (about 60.2%) of restrictive amino acids, and the highest protein efficiency ratio (Sujak et al 2006). Zralý et al (2007Zralý et al ( , 2008 and Písaříková et al (2008) found the following levels in the seeds of cultivated lupines: crude protein from 336.9 to 435.7, lysine from 16.4 to 22.6, methionine 401 et al (2000) from 2.6 to 5.0 and threonine from 11.6 to 15.8 g/kg DM. Dehulling resulted in the increase of protein and amino acid levels by approximately 13%.…”

“…In lupine species cultivated in Europe, the content of crude fibre ranged from 94.4 to 142.0 and acid detergent fibre (ADF) from 124.2 to 192.2 g/kg and was higher compared to soybean according to Straková et al (2006). Písaříková et al (2008) found in the seeds of cultivated lupine species markedly lower level of crude fibre (by 75%) and its components -neutral detergent fibre (NDF -by 70%), acid detergent fibre (ADF -by 69%), and acid detergent lignin (ADL -by 99%) due to dehulling.…”

Effect of dietary lupin (Lupinus albus) on the gastrointestinal microbiota composition in broiler chickens and ducks

“…As suggested in the introduction, the replacement of SBM with lupin meal in the diets of various monogastric animals, including rabbits, turkeys, chickens, and pigs, does not necessarily reduce weight gain (Wu et al 2004;Zraly et al 2008;Volek and Marounek 2009;Zdunczyk et al 2016). However, there have been some reports of weight loss with this replacement (Olkowski et al 2005;Smulikowska et al 2014).…”

“…Based on these requirements, low-alkaloid varieties of sweet lupin (Lupinus albus, Lupinus angustifolius, Lupinus luteus) are considered promising for use in animal feed. Its advantage is that lupin can be used to completely replace soybean meal (Zraly et al 2008;Hernandez and Roman 2016). The use of lupin as an alternative source of vegetable protein for the production of animal feed is increasing rapidly.…”

“…There are many studies analyzing the impact of replacing soya with lupin in animal diets. Many authors confirmed that lupin is a suitable protein component for use in animal feed, based on production parameters and nutrient digestibility in animals (Zraly et al 2008;Volek and Marounek 2009;Zdunczyk et al 2016;Zwolinski et al 2017). In addition to proteins, important growth-promoting factors in lupin seeds include their significant amounts of saccharides, including raffinose-series oligosaccharides (RSO).…”
