Effect of micronized pea seeds (Pisum sativum L.) as a substitute of soybean meal on tissue fatty acid composition and quality of broiler chicken meat

Abstract

This study aimed to evaluate the effect of micronized pea seeds introduced into feed mixes for broilers on the slaughter yield, blood lipid parameters, content of fatty acids in selected tissues, and meat quality. The studies involved 150 1-day-old Ross 308 chicks split into three groups (for 42 days). The feed rations differed in terms of the source of proteins: in the control group (C), it was post-extraction soybean meal (SBM) 100%; in group I, SBM 50% and micronized peas 50%; and in group II, micronized peas only, 100%. Irradiated pea seeds added to the feed ration for chicks reduced the fattening grade of carcasses (P < 0.05). Additionally, significant improvement of blood lipid indices was recorded. The share of the irradiated pea seeds in feed mixes decreased the share of saturated fatty acids in the muscles and abdominal fat and had a positive effect on the n-6/n-3 ratio, hypocholesterolemic / hypercholesterolemic ratio, as well as the atherogenic and thrombogenic indices (P < 0.05).

Chemical composition of leguminous seeds: part I—content of basic nutrients, amino acids, phytochemical compounds, and antioxidant activity

“…In turn, the white lupine (100.3 g kg − 1 DM) and the Andean lupine (155 g kg − 1 DM) proved to be oilbearing species. Similar ranges of the content of this nutrient in Fabaceae plant seeds were reported in literature [2,13,14,17].…”

Content of Minerals and Fatty Acids and Their Correlation with Phytochemical Compounds and Antioxidant Activity of Leguminous Seeds

“…The analysed seeds were characterised by a very high proportion of DFA with a neutral effect on the cholesterol level or hypocholesterolemic activity (on average 86%) and simultaneously with a low atherogenicity index (on average 0.15). In vivo animal and human investigations indicate great cardioprotective potential of legume seed fat [ 5 , 35 ].…”

“…Some studies indicate an ability of long-chain polyunsaturated fatty acids to act as antioxidants. Reduced excretion of lipid peroxidation products, lower production of reactive oxygen species (ROS), and direct superoxide scavenging by LC-PUFA, especially by those from the n -3 group, have been shown in in vivo data [ 35 ]. This was confirmed by evaluation of the interactions between the degree of DPPH free radical scavenging and the content of polyunsaturated fatty acids in quinoa seeds ( Chenopodium quinoa Willd.)…”

Inclusion of Camelina, Flax, and Sunflower Seeds in the Diets for Broiler Chickens: Apparent Digestibility of Nutrients, Growth Performance, Health Status, and Carcass and Meat Quality Traits

“…The content of dry matter and basic nutrients in the ground oilseed samples (250 g seeds/variety) was determined according to standard AOAC procedures [20] described in Section 2.4.1. Results are the average of 9 samples in three replicates, 1 Calculated by Kjeldhal nitrogen N × 6.25, 2 SFA-Saturated fatty acid, 3 MUFA-Monounsaturated fatty acids, 4 PUFA-Polyunsaturated fatty acids, 5 Fresh sample.…”

“…The quality of final products, like meat quality, in large-scale poultry production is ensured mainly through appropriate optimization of the composition of poultry diets [3]. Addition of full-fat seeds into diets for broiler chickens can modify the content of nutrients in birds' muscles to a certain extent, yielding a product with desired nutritional and dietary properties [4][5][6]. In this respect, the seeds of local oil-bearing plants, such as flax, camelina, or sunflower, seem to be extremely valuable [7][8][9].…”
