Effect of supplementation of garlic powder on rumen ecology and digestibility of nutrients in ruminants

Abstract

BACKGROUND: The present study investigated the effect of garlic powder (GAP) supplementation on rumen fermentation pattern, nutrient digestibility and intake in ruminants fed on straw as a roughage source.

Effects of plants containing secondary compounds and plant oils on rumen fermentation and ecology

“…Kongmun et al (2010a) reported that the proportion of butyrate tended to increase when supplemented with garlic powder (10.8-12.4 mol/ 100 mol in in vitro). This result was similar to that obtained by Wanapat et al (2008b) in vivo, who found that the supplementation of garlic powder in native beef cattle resulted in an increase in the proportions of butyrate. Busquet et al (2005) also observed similar result.…”

“…Based on an in vitro study, it was found that garlic powder and mangosteen peel powder resulted in lower rumen volatile fatty acid (VFA) production, while no such effect was observed in in vivo studies (Wanapat et al 2008b;Kongmun et al 2010). Benchaar et al (2006) have also reported that essential oil did not significantly change rumen fermentation.…”

“…However, it was found that the use of a mixture of 6% of coconut oil with sunflower oil (1:1) significantly decreased (P<0.05) propionate production. Only coconut oil (in vivo supplementation in native beef cattle) and garlic powder (in vitro supplementation in buffalo) increased the proportion of butyrate (Kongmun et al 2009(Kongmun et al , 2010(Kongmun et al , 2011Wanapat et al 2008b;Wanapat et al 2011). Kongmun et al (2010a) reported that the proportion of butyrate tended to increase when supplemented with garlic powder (10.8-12.4 mol/ 100 mol in in vitro).…”

“…Garlic and lemongrass are used as herb or spice by human for culinary. Garlic can be used as antimicrobial agents for the gastrointestinal tract, especially in the tropical regions of the world (Wanapat et al 2008b). …”

Effect of Artemisia Absinthium(Titween) on nutrient intake, digestibility, nutrient balance and blood biochemical of sheep

“…Since long manipulation of gut function and microbial habitat of domestic animal with feed additives of phytogenic origin can be a potential alternatives for enhancing rumen ecology (Wanapat et al, 2008), performance and health status of livestock (Manzanilla et al, 2001). However use of chemicals and antibiotics as livestock feed additives has been banned in European Union and in many countries because of the risk of accumulation of residues in animal products there by resulting in development of antibiotics resistance by several pathogenic microorganisms (Russell and Houlihan, 2003).…”
