Effect of supplementing hydroxy selenomethionine on meat quality of yellow feather broiler

Abstract

This study was conducted to evaluate the effect of supplementing hydroxy selenomethionine ( OH-SeMet ) on performance, selenium ( Se ) deposition in the breast muscle, quality and oxidative stability, and expression of selenoprotein encoding genes of breast meat of the native slow-growing yellow-feathered broiler birds. A total of 375 one-day-old local yellow male birds were randomly assigned into 5 dietary treatments, supplemented with Se 0.0, 0.2, 0.4, 0.6, and 0.8 mg/kg in the form of OH-SeMet. Each treatment consisted of 5 replicates and each replicate had 15 birds, the birds were fed on basal diet containing corn and soybean meal, and the experiment lasted for 63 d. The results showed that dietary Se supplementation linearly increased ( P < 0.001) Se contents in both serum and muscle, no significant changes ( P > 0.05) were observed on growth performance, yield of breast, meat color, and intramuscular fat deposition of the breast muscle. Dietary Se addition improved water-holding capacity, the pH 24h value, and tenderness of breast muscle, evidenced by a linear decreases of shear force ( P < 0.05), accompanied by lower thiobarbituric acid reactive substances and higher glutathione reductase activity. The mRNA abundance of selenoprotein encoding genes also responded to dietary Se levels. It is concluded that, dietary supplementation with OH-SeMet improved muscular Se deposition and meat quality of the native yellow birds, with enhanced antioxidant capability and regulation in selenogenome.

Low-protein diets supplemented with isoleucine alleviate lipid deposition in broilers through activating 5′ adenosine monophosphate-activated protein kinase and janus kinase 2/signal transducer and activator of transcription 3 signaling pathways

“…However, Ile supplementation significantly improved growth performance of broilers fed a LPD, partially in agreement with a previous study that reported significantly increased ADG and decreased F:G of broilers fed a diet supplemented with Ile ( Corrent and Bartelt, 2011 ). Chicken meat is an excellent source of animal protein for human nutrition, thus meat quality is especially important to the consumer ( Tang et al, 2021 ). The pH is an important parameter of meat quality.…”

Effects of dietary supplementation with selenium yeast and jujube powder on mitochondrial oxidative damage and apoptosis of chicken

“…In this study, the addition of selenium yeast and jujube powder to the diet can significantly reduce the MFI and increase the shear force of chicken breast after slaughter, which is consistent with the research of Vieira et al (2021) , this may be because the supplementation of natural antioxidants such as selenium yeast and jujube powder in the diet inhibited the activity of apoptotic enzymes and thus inhibited the degradation of chicken myofibrils by other means. However, studies have also shown that basal diets supplemented with different concentrations of selenium (in the form of hydroxy-selenomethionine) reduced postmortem shear stress in yellow feathered broilers ( Tang et al, 2021 ). Unlike the changes in chicken tenderness in this study, this may be because the type of chicken and the basal diet lead to differences in the experimental results.…”

Selenium and selenoproteins: their function and development of selenium‐rich foods

“…Tang et al . (2021) studied the effect of adding hydroxy selenomethionine (OH‐SeMet) on the meat quality of yellow‐finned broiler chickens. They found that adding OH‐SeMet to the feed improved the water retention capacity, tenderness of breast muscle and meat quality.…”

“…When the Se concentration was 60 mg/kg in the nutritional evaluation of Se-enriched mushroom protein by the RC method, the chemical score, essential amino acid index, biomass value, nutritional index and essential amino acid content of selenoproteins were all improved compared to the nonenriched group, indicating that selenoproteins have higher nutritional value than the control group of proteins. Tang et al (2021) studied the effect of adding hydroxy selenomethionine (OH-SeMet) on the meat quality of yellow-finned broiler chickens. They found that adding OH-SeMet to the feed improved the water retention capacity, tenderness of breast muscle and meat quality.…”
