“…Ando et al (2003) showed that feeding 200 g d -1 (30 g kg -1 of total dietary DM) of peppermint (Mentha piperita L.) to Holstein steers decreased the total number of protozoa, but this response did not occur in the current study in which the amounts of REO ingested were 100, 200 and 400 mg d -1 . Similar to present results, Newbold et al (2004) and Benchaar et al (2007) reported that ruminal protozoa counts were not affected when sheep and dairy cows were fed 110 and 750 mg d -1 of EO, respectively.…”

This study was conducted to evaluate the effects of rosemary essential oil (REO) on feed digestibility, ruminal fermentation and blood metabolites of Ghezel sheep. Four male sheep with average body weight 46 ± 2.0 kg were used in a 4 × 4 Latin square design. Treatments were control (no REO added), 100 mg d -1 of REO (low), 200 mg d -1 of REO (medium) and 400 mg d -1 of REO (high). Sheep were fed the 4 diets for 4 periods of 21 days (14 days as adaptation and 7 days for sample collection). The results showed that digestibility of dry matter, neutral-detergent fiber, aciddetergent fiber and crude protein were not affected by REO feeding (p > 0.05). The concentration of ammonia-N across sampling times was lower (p < 0.05) at low REO dosage compared with control. The molar proportion of acetate and butyrate across sampling times were lower at low REO dosage compared with control (p < 0.05). Total volatile fatty acids (VFA) concentrations at 4 h after morning feeding were reduced (p < 0.05) by adding 100 mg of REO d -1 to diet compared with the control, whereas medium REO dosage increased (p < 0.05) total VFA concentrations at 4 h post feeding compared with the control. The addition of REO had no effect on total protozoa counts across sampling times (p > 0.05). Supplementation with REO had no effect on plasma concentrations of glucose, triglyceride, cholesterol, total protein and albumin (p > 0.05). The results of this study indicate that, although a medium dose of REO may have positive effect on rumen fermentation, a low dose of REO may have adverse effects on ruminal fermentation.

“…Similar results with respect to total -N were also observed by addition of EO in CF-2 during the present study where as a significant decrease (p < 0.01) with increasing levels of oils, but no change in total-N has been earlier observed 58 with inclusion of peppermint oil in diet. The difference in total -N pattern in different experiments might be due to the difference in type and dose of essential oils used.…”

An in vitro trial was conducted in fermentation vessels under anaerobic conditions using composite feed-1 and composite feed-2 with inclusion of different levels of Eucalyptus oil (EO) along with buffered rumen liquor of sheep to observe the effects of oil on rumen methanogenesis and fermentation. The CF-1 consisted of 40% of concentrate and CF-2 had 25 % of concentrate.The various concentrations of EO used in present study were 0.5,1 and 2 µl/ml. During the present investigation it was observed that on increasing concentration of EO in CF-1 and CF-2 resulted in linear decrease in total gas production up to 74.26% in CF-1; and 31.01% by inclusion of EO in CF-2, respectively. The findings suggest that decrease in total gas production and methane concentration was highly pronounced in CF-1 compared to CF-2. The rumen digestibility in CF-1 and CF-2 also decreased significantly (p < 0.01) from control. A significant decrease in NH 3 -N compared to control was also documented. As EO in both the feeds was found to inhibit deamination activity, the ammonia production decreased with increase in the efficiency of protein utilization. The inclusion of the oil decreased the Total Volatile Fatty Acids (TVFA) concentration significantly (p < 0.01). The A:P ratio increased by inclusion in CF-2 but not in CF-1. The pH was effected on inclusion of EO in CF-2 whereas inclusion of EO in CF-1 exhibited non significant effect. Therefore, the difference in Volatile Fatty acids (VFA) pattern due to essential oil might be because of different diets and pH in different experiments. The inclusion of EO decreased the protozoa number significantly (p < 0.01). EO was found to decrease fermentation in a manner that even at 0.5 µl/ml concentration there was a significant decrease in GP, ME, SCFA, TDDM and MBP. It could therefore be envisaged that increasing the proportion of concentrate in diets and using EO as a feed additive increases the rumen efficiency by reducing the methane concentration and gas production.

“…The authors speculated that differences in VFA concentrations were due to accumulation of molecular hydrogen as a result of decreased methanogenesis. Ando et al (2003) observed a decrease in propionate concentration in ruminal fluid from cannulated Holstein steers that received 200 g dried peppermint daily compared with no peppermint supplementation. The authors postulated that the antimicrobial effects of menthol may have had an adverse effect on ruminal fermentation, thereby decreasing VFA production.…”

Fifty-two Holstein steers (573 ± 9.92 kg BW) were used to determine if oral administration of crystalline menthol would induce changes in endogenous secretions of IGF-1 and circulating concentrations of glucose, lactate, and plasma urea nitrogen (PUN). Steers were blocked by BW and assigned within block to treatment. Treatments consisted of 0, 0.003, 0.03, or 0.3% crystalline menthol (DM basis) added to the diet. Animals were housed in individual, partially covered pens equipped with feed bunks and automatic water fountains. On d 1 of the experiment, blood samples were obtained via jugular venipuncture at 0, 6, 12, 18, and 24 h after feeding. Treatment administration commenced on d 2, and blood samples were again drawn at 0, 6, 12, 18, and 24 h after feeding. This bloodsampling schedule was repeated on d 9, 16, 23, and 30. Plasma was analyzed for PUN, glucose, and lactate concentrations. Serum was used to analyze IGF-1 concentration. Body weights were measured on d 1, 9, 16, 23, and 30. To accompany the live animal phase, in vitro fermentations were performed using ruminal fluid cultures. Measurements included VFA concentrations and fermentative gas production for cultures containing crystalline menthol at 0, 0.003, 0.03, or 0.3% of substrate DM. Addition of menthol to the diet of steers resulted in a treatment × day interaction (P < 0.01) for concentrations of IGF-1, PUN, and plasma glucose. Cattle fed 0 and 0.003% menthol had greater serum IGF-1 concentrations on d 2 compared with steers fed 0.03% menthol. Steers fed 0% menthol had greater serum IGF-1 concentrations on d 9 compared with steers fed 0.03 and 0.3% menthol, whereas no differences were observed on d 23 or 30. Plasma glucose was similar among treatments until d 23, when steers supplemented with 0.03% menthol had lower glucose concentrations. Plasma urea nitrogen concentrations were not different among treatments; however, PUN concentrations varied by day. A linear response was detected for BW (P = 0.03), with steers consuming 0% menthol having the greatest BW and steers that consumed 0.3% menthol having the lightest BW until d 30. A menthol × day interaction was observed for daily feed deliveries (P < 0.01): cattle fed 0.3% menthol consumed less feed from d 5 through 12. Furthermore, in vitro gas production and VFA concentrations were unaffected by addition of menthol (P > 0.21). In conclusion, menthol supplementation minimally affected blood parameters associated with growth or ruminal fermentative activity.
