“…It is expected, therefore, that sources with more SFA profile (palm oil) are less harmful to fiber digestibility and intake (Wanapat et al, 2011). In contrast, this was not observed, since the palm oil treatment reduced the fiber digestibility in a manner similar to a source rich in UFA (linseed oil).…”

“…Reductions in DMI with inclusion of lipids in the diet are often observed (Bateman II and Jenkins, 1998;Wanapat et al, 2011). This effect is usually due to the interference of fatty acids in fiber digestibility (Jenkins, 1993) and inhibition of appetite due to the increase in serum concentrations of unsaturated fatty acids that activate satiety center receptors in the hypothalamus (Allen, 2000).…”

-The objective of this study was to evaluate the effect of lipid sources on voluntary intake, digestibility, performance, and CH 4 emission of Nellore steers grazing Brachiaria brizantha cv. Xaraés forage in the dry season. Forty-five Nellore steers with average weight of 442±34 kg were alloted into one of the five treatments: without additional fat; with palm oil; with linseed oil; with protected fat; and with whole soybeans. The supplements were provided daily and quantities were adjusted to 1% of body weight and diets were formulated in accordance with the Cornell Net Carbohydrate and Protein System. The experimental design was completely randomized with five treatments and two replications. There were no effects on dry matter, organic matter, and neutral detergent fiber intake with the inclusion of lipids in the diet. The neutral detergent fiber showed decreased digestibility in animals receiving linseed oil and palm oil treatments compared with animals receiving the diet without additional fat. The linseed oil treatment reduced CH 4 emissions by 38% when expressed in mg/d/kg BW and tended to reduce the emission in g/d/kg BW 0.75 . Lipid sources did not affect the weight gain of the animals. The intake and performance of grazing Nellore steers supplemented at 1% body weight with lipid sources were not modified. However, fiber digestibility was reduced with palm or linseed oil addition. Linseed oil reduced enteric CH 4 emissions. Linseed oil has the potential to reduce enteric CH 4 emissions in continuous tropical grazing systems based on B. brizantha grass.

“…Garlic powder significantly reduced (P<0.05) methane gas production (up to 22%). Also, supplementation of 7% coconut oil and a combination of 7% coconut oil in diet with 100 g/head/day of garlic powder significantly reduced (P<0.05) methane production, about 10% for both the treatments (Kongmun et al 2011;Wanapat et al 2011). Calsamiglia et al (2007) mentioned that the synthesis of the isoprenoid units in methanogenic Archaea is catalyzed by hydroxymethylglutaryl coenzyme-A (HMG-CoA) reductase, an enzyme that has also been shown to be present in the liver and that also participates in the synthesis of cholesterol.…”

“…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).…”

“…The compounds considered to be responsible for the anti-protozoal effect are saponins or saponin-like substances (Hess et al 2006;Pilajun and Wanapat 2011). Moreover, essential oil and some plant secondary compounds have been used as additives to improve rumen fermentation (Kongmun et al 2010;Mapato et al 2010;Wanapat et al 2011). Therefore, the objective of this review was to understand the effects of plant secondary compounds and plant oil supplementation on rumen fermentation and ecology in ruminants (Table 1).…”

A number of experiments have been conducted to investigate effects of tropical plants containing condensed tannins and/or saponins present in tropical plants and some plant oils on rumen fermentation and ecology in ruminants. Based on both in vitro and in vivo trials, the results revealed important effects on rumen microorganisms and fermentation including methane production. Incorporation and/or supplementation of these plants containing secondary metabolites have potential for improving rumen ecology and subsequently productivity in ruminants.

Abstract:The effects of linoleic acid (LA) supplementation on in vitro dry matter disappearance (DMD), gas production, methane and hydrogen gas production, ruminal fermentation characteristics, and fatty acids (FA) profiles in fermentation fluid were investigated in vitro. Rumen fluid was collected from four ruminally cannulated goats, diluted with incubation buffer, and then incubated with 500 mg Leymus chinensis meal supplemented with different amounts of LA (0, 20, 40, and 60 mg for the control, LA20, LA40 and LA60 groups, respectively). In vitro rumen incubation was anaerobically carried out in 130-mL sealed fermentation bottles at 39°C for 48 h, and samples were collected at three time points (12, 24, and 48 h) for analysis. Supplementation of LA reduced DMD (P < 0.05), the cumulative gas production, theoretical maximal gas production and methane production (P < 0.05), whilst increased the hydrogen gas production. In addition, LA addition to substrate had no negative effects on ruminal fermentation parameters (pH, NH 3 , and VFA). The concentration of total polyunsaturated fatty acid (PUFA) and conjugated linoleic acid (CLA) were higher for LA groups than for control during the whole incubation process. These results indicate that LA supplementation in substrate reduce gas and methane production, and increase the amounts of some beneficial fatty acids in fermentation liquid in vitro.
