摘      要：Background:Methane production and fatty acids(FA)biohydrogenation in the rumen are two main constraints in ruminant production causing environmental burden and reducing food product *** functions can be modulated by the biologically active compounds(BACs)of plant origins as shown in several studies *** in methane emission,modulation of FA composition with positive impact on the ruminant *** amboinicus Lour.(CAL)contains high concentration of polyphenols that may potentially reduce methane production and modulate ruminal biohydrogenation of unsaturated *** study aimed to investigate the effect of BAC of Coleus amboinicus Lour.(CAL)fed to growing lambs on ruminal methane production,biohydrogenation of unsaturated FA and meat *** this study,the in vitro experiment aiming at determining the most effective CAL dose for in vivo experiments was followed by two in vivo experiments in rumen-cannulated rams and growing *** 1(RUSITEC)comprised of control and three experimental diets differing in CAL content(10%,15%,and 20%of the total diet).The two in vivo experiments were conducted on six growing,rumen-cannulated lambs(Exp.2)and 16 growing lambs(Exp.3).Animals were assigned into the control(CON)and experimental(20%of CAL)*** parameters were examined in vitro(pH,ammonia and VFA concentrations,protozoa,methanogens and select bacteria populations)and in vivo(methane production,digestibility,ruminal microorganism populations,meat quality,fatty acids profiles in rumen fluid and meat,transcript expression of 5 genes in meat).Results:CAL lowered in vitro methane production by 51%.In the in vivo Exp.3,CAL decreased methane production by 20%compared with the CON group,which corresponded to reduction of total methanogen counts by up to 28%in all experiments,notably *** Exp.3,CAL increased or tended to increase populations of some rumen bacteria(Ruminococcus albus,Megasphaera elsdenii,Butyrivibr
