The chemical composition of domestic soybean seeds and the effects of partial substitution of soybean meal by raw soybean seeds in the diet on pigs’ growth performance and pork quality (m. longissimus lumborum)

Abstract

The objective of the study was to determine the effect of the introduction of 5% of raw soybean seeds instead of soybean meal on the growth, feed consumption and utilization of growing pigs, also the carcass and pork quality. The growth experiment was conducted on 120 pigs of approx. 18.5 kg allocated to two dietary treatments. The animals from the control treatment (CON) were offered a diet with soybean meal, and the experimental group (EXP) was given 5% raw soybean seeds (NON-GMO, Augusta var.) instead of SBM. The experiment lasted 88 days. After the experiment, eight pigs from each group were euthanized and meat samples were collected. No diet effect on the animals’ performance and carcass quality were observed (P>0.05). The experimental diet affected (P<0.05) meat color, and also meat composition (higher water content and lower intramuscular fat content). The composition of fatty acids in the meat did not differ significantly, except for higher C16:1 content in the EXP group.

The introduction of 5% raw soybean seeds in the diets did not impact animal performance, but it reduced some indices of the pork quality.

Impact of Globulins Derived from Genetically Modified and Conventional Soybean on Swine Lymphocyte Proliferation in in vitro Cultures

Impact of Globulins Derived from Genetically Modified and Conventional Soybean on Swine Lymphocyte Proliferation in in vitro Cultures

The majority of the global feed market is dominated by the Roundup Ready 40-3-2 transgenic soybean varieties developed and marketed by Monsanto Company, which are characterized by tolerance to glyphosate, the active ingredient of the Roundup herbicide. It should be remembered, however, that soybean is one of the major allergens which may affect animal health. The aim of the study was to compare allergenic properties of globulins derived from genetically modified (GM) soybean imported from the USA and conventional soybean developed in Poland. Analyses were performed by measuring porcine lymphocyte proliferation in in vitro cultures. It turned out that both genetically modified and conventional soybean proteins caused immune response at the level of negative control. A slight increase in relation to the negative control was observed in the case of 7S and 11S fractions derived from the GM meal and 7S fraction isolated from Nawiko meal.
