This analysis explores allicin’s effects upon growth performance, various meats quality, and economical benefits in cows and sheep, maintained scientific data and comparative analyses.
Summary of Allicin in Ruminant Nutrition
Allicin, a new sulfur-containing compound from garlic, is made via the enzymatic reaction of alliin along with alliinase, yielding some sort of potent bioactive together with antibacterial, antioxidant, in addition to immune-enhancing properties. While a natural supply additive, allicin is a viable alternative to remedies in cattle plus sheep production, addressing antimicrobial resistance concerns. It influences rumen fermentation, nutrient digestibility, and immune purpose, enhancing growth performance and meat quality. Its efficacy may differ with dosage (e. g., 0. 5–1 g/head/day), form (synthetic, garlic powder, or extracts), and types. This document evaluates allicin’s impact upon growth performance, meats quality, and monetary benefits in ruminants.
Effects on Expansion Performance
Allicin enhances growth performance within cattle and lamb by improving nourish intake, nutrient digestibility, and rumen microbes activity. Research about Small-Tailed Han sheep fed 7. a few g/kg allicin in concentrate diets confirmed significant increases inside average daily supply intake (DMI) (P <0.05) and a 35.29% higher average daily gain (ADG) compared to controls (e.g., 140 g/d vs. 95.6 g/d in Guizhou black goats at 0.75 g/head/day). Feed conversion ratio (FCR) improved by 33.9% (8.73 vs. 13.2) in goats fed 0.75 g/head/day allicin, with linear analysis indicating a positive correlation between allicin dosage and ADG (P=0.013). These effects are attributed to allicin’s ability to reshape rumen microbiota, increasing populations of beneficial bacteria like Alloprevotella, which enhance nutrient digestion. In dairy cows, adding allicin (e.g., 2% garlic powder) increased dry matter digestibility by 5–7% and milk yield by 3–5% (e.g., 28 kg/d vs. 26 kg/d in controls), with no adverse effects on rumen pH. However, high doses (> 1 g/head/day) may reduce palatability, decreasing DMI simply by 5–10% in certain cattle studies. Allicin in addition reduces methane exhausts by 15–20% by inhibiting methanogenic germs, improving energy efficiency.
