The Effect of Yeast (Saccharomyces Cerevisae), Garlic (Allium Sativum) and Their Combination as Feed Additives in Finishing Diets on the Performance, Ruminal Fermentation, and Immune Status of Lambs

“…In vitro dry matter digestibility (IDMD) was not statistically (P> 0.05) significant, GP 0.5% group had numerically higher value (68.11%) while the control had the least value of 65.23%. The addition of garlic powder to the diet of rams considerably reduced production of CH 4 by 38% (Kim et al, 2018).…”

Effects of L-glutamine supplementation on degradation rate and rumen fermentation characteristics in vitro

“…Any change in its pH can strongly affect the vigor of rumen microbes and their activity [ 23 ]. When the pH value is more than 7, utilization of ammonia is reduced [ 12 ]. Meanwhile, when the pH value is less than 6.2, the degradation activity of cellulose is decreased, causing slower degradation of cellulose wall, lower growth of microorganisms, and lower production of VFAs and methane [ 25 , 26 ].…”

“…Higher in-vitro total gas production reveals higher fermentation end products that could be preferable [ 11 ]. Total gas results can also be estimated from molar percentage of VFA [ 12 , 28 ]. Protein and starch are digested by microorganisms such as bacteria, protozoa, and fungi to produce sugar and AAs.…”

“…Any change in its pH can strongly affect the vigor of rumen microbes and their activity [23]. When the pH value is more than 7, utilization of ammonia is reduced [12].…”

“…Understanding the optimum level of Gln supplementation by performing in-vitro study will assist to make a better decision to maximizing the muscle growth in empirical in-vivo studies in beef cattle while help avoiding possible toxic level(s). The effects of AA supplementation on the production of volatile fatty acids (VFAs) triggered by ruminal microorganisms that ultimately can affect cell growth and production performance is of importance [ 11 , 12 ]. Warner [ 13 ] stated that microorganisms from the rumen of sheep rapidly break down Gln to other components such as asparagine and nicotinamide resulting in exceeding ammonia production which in turn can lead to Gln synthesis.…”
