Effects of the Dietary Inclusion of Allium mongolicum Regel Extract on Serum Index and Meat Quality in Small-Tailed Han Sheep

Abstract

The aim of this study was to evaluate the effects of Allium Mongolicum Regel ethanol extract (AME) on the serum index and meat quality of lambs. A total of 30 male Small-tailed Han sheep (3 months old) with an average weight of 33.60 ± 1.23 kg were divided randomly into one of two groups: the control group (CON) was offered a basal diet, and the AME group was offered a basal diet with supplementation 2.8 g·lamb−1·day−1 AME. The trial lasted for 75 days. AME supplementation significantly decreased the concentration of triglyceride and total cholesterol (p < 0.05), and tended to lower the concentration of non-esterified fatty acids (0.05 < p < 0.1), but significantly increased the concentration of high-density lipoprotein, leptin, and insulin (p < 0.05) in the serum of lambs. AME also decreased cooking losses and shear force and increased the content of intramuscular fat in the longissimus dorsi (LD) muscle of lambs (p < 0.05). In addition, there was no difference in the composition of hydrolyzed protein amino acids in the LD muscle among treatments (p > 0.05). However, AME changed the composition of free amino acids and promoted MUFA and PUFA deposition in the LD muscle of the lambs. These findings indicate that a diet supplemented with AME may improve the lipid metabolic capacity and meat quality of lambs.

Whole genome sequencing identified genomic diversity and candidated genes associated with economic traits in Northeasern Merino in China

“…Among them, CDC42BPB may affect the synthesis of 3-hydroxybutyric acid and thus the quality of meat ( Li et al, 2022 ). And “high-density lipoprotein particle, GO:0034364” ( LOC101120204 , LOC101120613 , and LOC105601867 ) ( Supplementary Table S11 ), which is a cellular component term involved in the transport of lipids ( Zhao et al, 2022b ).…”

Stall-Feeding of Sheep on Restricted Grazing: Effects on Performance and Serum Metabolites, Ruminal Fermentation, and Fecal Microbiota

“…Statistical analyses of indices related to growth performance, serum parameters, ruminal fermentation, and fecal microbiota were analyzed using a general linear model routine in SPSS software (Version 25.0, SPSS Inc., Chicago, IL, USA). The effect of feeding system on all variables was analyzed with the statistical linear model: Y i = μ + D i + E, where Y i is the dependent variable, μ is mean value, D i means the fixed effect of feeding system, and E means the random effect [ 36 ]. Significance was determined at a level of p ≤ 0.05.…”

Potential modulating effects of Allium mongolicum regel ethanol extract on rumen fermentation and biohydrogenation bacteria of dairy cows in vitro

“…The extracts of AMR have been shown to regulate the rumen environment and FA metabolism by increasing the concentration of total VFA and propionic acid in the rumen and the contents of UFAs in the longissimus dorsi muscle of lambs (Liu et al, 2019). Recent research reported that C17:0, and C18:0, which correlated with the "mutton flavor" of Small-Tailed Han sheep were decreased by adding AME (Watkins and Frank, 2019;Zhao et al, 2022b). The structure of rumen microflora is closely related to FA deposition in the longissimus dorsi muscle.…”

“…The structure of rumen microflora is closely related to FA deposition in the longissimus dorsi muscle. Diet supplemented with AME changed the rumen fermentation pattern and the structure of rumen microflora (Zhao et al, 2022c), thus influencing the FA metabolism by improving MUFA and PUFA deposition in longissimus dorsi muscle (Zhao et al, 2022b). Existing research has demonstrated that AMR has significantly modulating effects on rumen microbial flora and FA metabolism in mutton sheep, its potential modulating effects on the rumen of dairy cows remain unknown.…”
