Abstract

The objective of this study was to evaluate carcass and meat quality in growing-finishing pigs fed diets with different vegetable protein sources. It was found that partial (50% in grower diets) and complete (100% in finisher diets) replacement of protein from genetically modified soybean meal (GM-SBM) with protein from 00-rapeseed meal (00-RSM), alone or in combination with protein from faba bean seeds (FB) cv. ‘Albus’, yellow lupine seeds (YL) cv. ‘Taper’ or corn DDGS, had no significant effect on carcass quality characteristics or the chemical composition of meat. In all groups, meat samples were characterized by color typical of pork, high water-holding capacity and low pH values. A sensory analysis of the eating quality attributes of meat revealed that they were highly satisfactory; only aroma intensity was affected by the experimental factor. The study demonstrated that growing-finishing pigs can be fed complete diets containing the analyzed vegetable protein sources alternative to GM-SBM without compromising carcass or meat quality.

Highlights

In modern pig farming, fattening is based on complete diets whose nutritional value must support the growth rate of animals and protein deposition potential
The experimental factor had a significant influence only on aroma intensity, and the meat of pigs fed faba bean seeds (FB) seeds scored highest for this attribute
The results of this study indicate that partial (50% in grower diets) and complete (100% in finisher diets) replacement of protein from genetically modified soybean meal (GM-soybean meal (SBM)) with protein from 00-rapeseed meal (00-RSM), alone or in combination with protein from FB seeds cv

Summary

Introduction

In modern pig farming, fattening is based on complete diets whose nutritional value must support the growth rate of animals and protein deposition potential. Various measures have been adopted to prevent the spread of these diseases, including a ban on the use of meat and bone meals in animal feeds, which was introduced in the European Union (EU) in 2001 (EC 2001). This ban has been amended (EU 2021) and some of the processed animal proteins (nearly comparable to meat and bone meal) is allowed to be fed to pigs in EU. High fluctuations in the prices and supply of GM-SBM (Woyengo et al 2014) and the need to ensure feed protein security have prompted a search for alternative, cheaper sources of plant based protein such as legume seeds, by-products of 00-rapeseed processing and distillers grains
