Nucleotides in broiler chicken diet: effect on breast muscles quality

Abstract

Chiofalo B., Lo Presti V., Savoini G., D'Alessandro E., Chiofalo V., Liotta L. (2011): Nucleotides in broiler chicken diet: effect on breast muscles quality. Czech J. Food Sci., 29: 308-317.The study evaluated the effects of nucleotide dietary supplementation on the physical and nutritional characteristics of the Pectoralis major muscle of male broiler chickens (n = 60 000), divided into two homogeneous groups: Control (C) and Nucleotides (N). The animals of the two groups, from the birth (24 h of age) to the slaughtering age (52 days), received the same diet, supplemented (N) or not (C) with 0.1% of a Nucleotide pool. At the slaughtering, on a sample of 130 animals per group, randomly selected, the physical and nutritional characteristics of Pectoralis major muscle were determined. The meat of the N group showed significantly higher redness and Hue values, lower shear force values, higher lipid and ash percentages and iron content. Moreover, nucleotides significantly increased monounsaturated acids and linolenic acid and decreased eicosapentanoic and docosahexanoic acids. The unsaturation degree was higher in the Nucleotides group and Atherogenic index was positively influenced by the nucleotide supplementation. Nucleotide dietary supplementation improved the physical and nutritional characteristics of the Pectoralis major muscle of broiler chickens.

Effects of Dietary Nucleotides Supplementation on the Perfor-Mance of Broiler Chicks

“…Effect of nucleotides dietary supplement on meat quality Significant changes were found between the groups, as shown in Shawn's table 7, where the addition of nucleotides and USFA oil sources to the diet gradually reduced the n-6: n-3 ratio in the breast muscle. These findings corroborated those of Chiofalo et al (11), who concluded that meat had better nutritional qualities because it included more lipids with greater unsaturation degrees, which had positive impacts on human health when consumed with nucleotides.…”

“…Nucleotide-fed birds had higher body weights and, as a result, delivered more carcasses, including heavier drumsticks, thighs, wings, and breasts (7). Additionally, their meat had greater nutritional qualities, was redder in color and tender, and had more lipids with higher unsaturation degrees, all of which are good for humans' health and are aesthetically acceptable to consumers (11).…”

Antioxidant capacity in broiler chicken enhanced by nucleotides and/or beta-glucan, resulting in increased antioxidant-related gene expression plus enzymes and improved meat quality

“…Structural components of β-glucans may have an impact on the activities of enzymes associated with antioxidants, particularly SOD and CAT, which are recognized as crucial in protecting cells from stress caused by oxidation (He et al, 2021). When comparing the control group to the groups that received nutritional supplements, the outcomes of meat quality in table (4) are accepted by Chiofalo et al (2011) and Salah et al (2019), those who reported that the meat of the nucleotide-supplemented group had no effects on color or PH. In addition, the lack of yellowing in breast meat after β-glucan therapy was illustrated by Zhang et al (2012), perhaps due to reduced abdomen fat.…”

Muscle growth affects the metabolome of the pectoralis major muscle in red-winged tinamou (Rhynchotus rufescens)

“…Another interesting observation of the present study is the high concentrations of ADP, AMP, ATP, adenosine, IMP, inosine, NAD+, and acetate in the TinamouS group. These metabolites are involved in cell growth and division, modulation of the immune system and the maintenance of intestinal health, participate directly in the metabolism of other compounds through biochemical processes, and are related to energy production, storage and expenditure ( Chiofalo et al, 2011 ; Faveri et al, 2015 ; Wen et al, 2020 ). Some authors suggest that the lementation of broiler chicken diets with nucleotides can improve the physical and nutritional characteristics of breast meat and promote higher weight gain and feed conversion ( Chiofalo et al, 2011 ; Jung and Batal, 2012 ; Faveri et al, 2015 ).…”
