The Effect of Dietary Supplementation with Inorganic or Organic Selenium on the Nutritional Quality and Shelf Life of Goose Meat and Liver

Abstract

Ninety-six male goslings were allocated and assigned to treatment using a completely randomized design. Dietary treatments included a basal diet consisting of corn, wheat, and soybean meal with either no additional selenium (CON), 0.3 mg/kg of inorganic selenium (I-Se; sodium selenite), or 0.3 mg/kg of organic selenium (O-Se; selenium-enriched yeast). After a 56-day feeding period, geese were slaughtered on a common ending day and two geese per pen (n = 24) were used for the analyses conducted in this study. Meat (equal portions of the breast and thigh meat) and liver were collected and evaluated for proximate composition, fatty acid profile, pH, phenolic content, thiobarbituric acid reactive substances (TBARS), and total volatile basic nitrogen (TVB-N) over a 9-day storage period at 4 °C. The meat and liver samples from geese supplemented I-Se or O-Se had greater (p < 0.01) lipid content compared with geese not supplemented with additional selenium. At the conclusion of the 9-day storage period, meat and liver samples from geese supplemented I-Se or O-Se had lower (p < 0.05) pH values, greater (p < 0.05) phenolic content, lower (p < 0.05) TBARS values, and lower (p < 0.05) TVB-N compared with geese not supplemented with additional selenium (CON).

Combined effects of calcium‐alginate coating and Artemisia fragrance essential oil on chicken breast meat quality

“…The TPC of chicken meats coated with CA +AFEOs was significantly ( p < .05) (117.32–130.47 mg GA (gallic acid equivalent)/100 g DM (dry matter)) higher than that of control samples (110.28 mg GA/100 g DM). The presence of high phenolic components in plant EOs (Nemati et al., 2021 ; Shirzad et al., 2021 ) might be the principal reason for the high TPC in coated meat samples. Alirezalu, Hesari, et al.…”

Impact of Ginger Root Powder Dietary Supplement on Productive Performance, Egg Quality, Antioxidant Status and Blood Parameters in Laying Japanese Quails

“…The contents of bioactive components were determined in the extract and the concentration of 6-gingerol, 8-gingerol, 10-gingerol, and 6-shogaol was 6163.1, 802.8, 783.9, and 839.9 mg/kg ginger (on dry weight basis), respectively. Nutrient compositions and total phenolic content of ginger root powder were analyzed according to standard method, Association of Official Analytical Chemists (AOAC) [33] and Nemati et al [34], respectively and the results are given in Table 2.…”

“…The eggshell percentages were calculated using washed and dried eggshell weights [35]. For pH analysis, yolk and albumen were completely mixed with a glass rod prior to measurement separately (pH meter; Hanna 211, Woonsocket, RI, USA) [34].…”

New horizons for selenium in animal nutrition and functional foods

“…After absorption, selenate may undergo enzymatic activation with ATP to form adenosine-5′-selenophosphate, which is either catalyzed by thioredoxin or thioredoxin reductase (TrxR) or reduced to the intermediate selenodiglutathione by glutathione reductase, ultimately generating H 2 Se ( Burk and Hill, 2015 ). Inorganically sourced Se recombines with other nutrients in the intestine, forming insoluble complexes that are excreted, which reduces the absorption of Se in the small intestine ( Nemati et al., 2021 ).
