Effect of dietary Alibernet red grape pomace application into Ross 308 broiler chickens diet on amino and fatty acids profile of breast and thigh meat

Abstract

The aim of this study was to determine the effects of Alibernet red grape pomace (ARGP) variety Alibernet addition into broiler chickens Ross 308 diet on the essential amino acid (AA) and fatty acid (FA) composition of their breast and thigh meat. At the beginning, 200 one-day Ross 308 broiler chickens of mixed gender were randomly divided into 4 groups ( n = 50). The control group (C) did not receive any additional supplementation. The feed of experimental groups was enriched with 1% ARGP per 1 kg of feed mixture (FM) (E1), with 2% ARGP per 1 kg of FM (E2) and with 3% ARGP per 1 kg of FM (E3). The FMs were produced without any antibiotics and coccidiostatics and the fattening period lasted for 42 days. Samples from breast and thigh muscle were obtained and analyzed for the content of AAs and FAs content and results were presented as g 100 g -1 of dry matter. Results revealed that AA profile of breast muscle was not significantly affected, with the most present AAs Lys and Leu. In the thigh muscle we observed significant differences in the content of Thr, Val, Met, Cys and His, namely in males. From the results of FAs profile, we can state that ARGP influenced namely monounsaturated oleic acid in breast muscle (without gender difference), which had significantly highest content ( p ≤ 0.05) in all experimental groups (E1–36.05, E2–35.60 and E3–36.79 g 100 g -1 ) compared with the control group (31.88 g 100 g -1 ). Overall, it seems that selected feed supplement did not negatively influence AAs and FAs profile of chicken meat.

Selected fruit pomaces: Nutritional profile, health benefits, and applications in functional foods and feeds

“…The findings revealed that the gradual increments of dried AP deteriorated growth performance, modified total antioxidant capacity, antibody titer production, and blood profile of broilers. Haščík et al (2023) have also determined Alibernet variety derived Alibernet red grape pomace (ARGP) effects on inclusion into Ross 308 broiler chicken diet containing fatty acid (FA) and essential amino acid (AA) in the thigh and breast meat. Three experimental groups based on the varying amounts of ARGP in feed were assigned, first (E1) being 1 % ARGP/kg enriched feed mixture (FM), second (E2) being 2 % ARGP/kg enriched FM and third (E3) being 3 % ARGP/kg enriched FM.…”

“…Consequently, the commercial use of various fruit pomaces has become a popular research interest. Currently, it is used as a food ingredient substitute, feed ingredient, and nutritional supplement for animal and human consumptions ( Acharjee et al, 2021 ; Ali et al, 2021 ; Ao et al, 2022 ; Kesbiç et al, 2022 ; Rehal et al, 2022 ; Gumul et al, 2023 ; Haščík et al, 2023 ). With the increase in application of fruit pomace as evident from the Web of Science (WOS) data between years 2001–2024 and hence, has also included fruit pomace as the search string.…”
