AbstractEnteric methane production contributes significantly to the greenhouse gas emission globally. Although, buffaloes are integral part of livestock production in Asian countries, contributing milk, meat and draft power, the contribution of enteric methane to environmental pollution attracts attention. The present study investigated the efficacy of garlic (Allium sativum) oil in reducing enteric methane production from buffaloes (Bubalus bubalis) by in vitro rumen fermentation. Garlic oil (GOL) was tested at four concentrations [0 (Control), 33.33 µl (GOL-1), 83.33 µl (GOL-2) and 166.66 µl (GOL-3) per litre of buffered rumen fluid] in 100-ml graduated glass syringes and incubated at 39℃ for 24 h for in vitro rumen fermentation study. Supplementation of GOL-1 increased (p < 0.05) total gas production in comparison with GOL-3; however, it remained comparable (p > 0.05) with control and GOL-2. Graded doses of garlic oil inclusions reduced (p < 0.001) methane concentration (%) in total gas and total methane production (ml/g DM), irrespective of concentrations. The feed degradability, volatile fatty acids and microbial biomass production (MBP) were not affected (p > 0.05) by GOL-1, but these tended to decrease in GOL-2 with marked reduction (p < 0.01) in GOL-3. The decrease (p < 0.01) in NH3–N concentration in fermentation fluid in the presence of garlic oil, irrespective of concentration, suggests reduced deamination by inhibiting rumen proteolytic bacterial population. The activities of ruminal fibrolytic enzymes (CMCase, xylanase, β-glucosidase, acetyl esterase) were not affected by lower dose (GOL-1) of garlic oil; however, reduction (p < 0.05) of these enzymes activity in rumen liquor was evident at higher doses (GOL-2 and GOL-3) of supplementation. This study shows positive impact of garlic oil supplementation at low dose (33.33 µl/l of rumen fluid) in reducing enteric methane production, thereby, abatement of environmental pollution without affecting feed digestibility.

Abstract Galectins (GAL) constitute an evolutionarily conserved family of β-galactoside-binding proteins that are secreted. They are involved in the regulation of homeostasis, innate and adaptive immune responses to infectious challenge. The mushroom Coriolus versicolor (CV) has been reported to boost suppressed immune function, extending the survival rate and improving quality of life in man. The objective of this study was to evaluate the effect of mushroom probiotics on the secretion of Galectins in goat blood. Ten BoerXSpanish female goats (5 weeks of age) were used for this study. Powdered CV was soaked in cold water and sterile filtered. Following initial screening for infection, goats were assigned to two groups of five (n = 10). Goats were drenched daily with 10 mL cold (treatment I) extract for 4 weeks. A control group of five age-matched goats received sterile water (treatment II). Blood samples were collected on a weekly basis. The concentration plasma protein was determined by using Pierce BCA kit (Thermo Scientific Pierce, Rockford, IL). Galectins-1, -3, -8, -9 and -12 concentration was detected by using a commercial ELISA kits (ABclonal Biotechnology, Woburn, MA). There was an effect of treatment in total plasma protein concentration when compared to the control group (P &lt; 0.02). Galectins tested were secreted in both control and treatment groups. Treatment with CV decreased the concentration of Gal-1, 8 and 9 and increased the concentration of Gal-3 and -12 (P &lt; 0.05). Results from this study indicate that mushroom probiotics can modulate the secretion of GAL.
