Effects of allicin addition on growth performance, rumen microbiome, and ruminal epithelial proteome of high-grain-fed goats
It is well known that allicin has anti-bacterial, anti-oxidation, and anti-inflammatory biological functions. However, there is little information on whether allicin has beneficial effects on ruminants fed a high-grain (HG) diet. This study was conducted to investigate the effects of allicin addition on growth performance, ruminal microbes in different rumen ecological niches (REN), and the rumen epithelial (RE) proteome in fattening goats fed a HG diet. Twenty-four Anhui white goats were randomly allocated to three dietary treatments: control diet (CON, n = 8), high-grain diet (HG, n = 8), and high-grain diet + allicin (HGA, n = 8). After 56 days, blood, rumen fluid (RL), rumen solid (RS), and RE tissue were sampled for further analysis. Compared with the HG diet, the addition of allicin decreased (P < 0.05) the DMI, with no effects (P > 0.05) on daily weight gain and rumen fermentation parameters. The malondialdehyde concentrations were lower (P < 0.05) in the HGA group than in the HG group. The HGA group had a higher activity of glutathione peroxidase in the rumen epithelium than the HG group. The alpha diversity in different REN in the HGA group was higher (P < 0.05) than that in the HG group. Compared to the HG group, the HGA group had higher relative abundances of Lachnospiracea_incertae_sedis, Ruminobacter, and Bifidobacterium (P < 0.05), and lower relative abundances of Methanomassiliicoccus (P < 0.05). The addition of allicin helped mitigate or reverse the differences between the HG diet and the CON diet at the genus level in different RENs. Proteomic analysis of the rumen epithelium showed that proteins involved in cell junction and immune function were downregulated, whereas those involved in oxidative stress and inflammatory reactions were upregulated in the HG group in comparison with the CON group. Compared with the HG group, the addition of allicin increases the abundance of proteins involved in cell junction and immune function and decreases those of proteins involved in oxidative stress and inflammatory reactions. Our findings indicate that the addition of allicin can improve the antioxidant capacity, modify the rumen microbial composition, alleviate the damage to the rumen epithelium cell junction, and protect the rumen epithelium of goats fed a HG diet.
期刊介绍:
Animal Feed Science and Technology is a unique journal publishing scientific papers of international interest focusing on animal feeds and their feeding.
Papers describing research on feed for ruminants and non-ruminants, including poultry, horses, companion animals and aquatic animals, are welcome.
The journal covers the following areas:
Nutritive value of feeds (e.g., assessment, improvement)
Methods of conserving and processing feeds that affect their nutritional value
Agronomic and climatic factors influencing the nutritive value of feeds
Utilization of feeds and the improvement of such
Metabolic, production, reproduction and health responses, as well as potential environmental impacts, of diet inputs and feed technologies (e.g., feeds, feed additives, feed components, mycotoxins)
Mathematical models relating directly to animal-feed interactions
Analytical and experimental methods for feed evaluation
Environmental impacts of feed technologies in animal production.
