“…A review by Beauchemin et al (2008) estimated that CH 4 production in ruminants is reduced by 5.6% for every 1% increase in added dietary lipid. Girón et al (2016) observed that the addition of 40 g kg -1 of corn oil to the diet of dairy cows decreased CH 4 production by 16%. Maleki et al (2016) reported a decrease in CH 4 concentration when pomegranate oil was added to rumen cultures at 10 mg 75 ml -1 .…”

M. Embaby, M. Günal, and A. AbuGhazaleh. 2019. Effect of unconventional oils on in vitro rumen methane production and fermentation. Cien. Inv. Agr. 46(3): 276-285. The effects of unconventional oils high in polyunsaturated fatty acids (PUFAs) (blackberry, blueberry, raspberry, pomegranate, black seed and hemp oils) on in vitro rumen fermentation and methane (CH 4 ) production were examined in a 24-h batch culture experiment. Treatments consisted of a control (no oil supplement), a control plus corn oil, or a control plus the unconventional oils. Oils were added to rumen cultures at 500 mg L -1 (equivalent to 3.3 g oil.kg -1 of dietary dry matter (DM)). After 24 h of incubation, CH 4 production was not different between the control and the corn oil treatment. Of the six unconventional oils tested, only the hemp and blueberry oils reduced CH 4 production by 10-16% relative to that of the control and corn oil treatments. Dry matter degradability and total volatile fatty acids (VFAs) were not affected by the addition of oils. Except for a reduction in the acetate concentration with the raspberry and hemp oils, all tested unconventional oils had no effects on fermentation and the VFA profile relative to those of the control. In conclusion, our results showed that hemp and blueberry oils were moderately effective in reducing rumen CH 4 formation without compromising rumen fermentation and digestibility.

“…Corn oil are easy to get and contains plenty unsaturated long chain fatty acids. The major fatty acids in corn oil is linoleic acids (C18:2) up to 53.99% (Giron et al, 2016). Palm oil is cheap and highly available and composed mainly of palmitic acid (C16) 32-37% and oleic acid (C18:1) 46.14% (Sitoresmi et al, 2009).…”

“…According to Giron et al (2016), supplementing 4% corn oil in the dairy cows increased milk production and milk fat concentration, decreased the VFA molar production without interfere the molar ratio of acetate, propionate ad butyrate. Supplementation of 5% palm oil increased the growth and efficiency of feed conversion in weaning lamb (Dutta et al, 2008).…”

This research was aimed to determine the effect of supplementation of vegetable oil (corn oil, palm oil and kapok seed oil) on in vitro ruminal fermentability and nutrient digestibility. Experiment design used was Randomized Block Design with four treatments and four replication based on rumen fluid sampling time. The four treatments namely R0 = feed without oil supplementation; R1 = R0 + 5% corn oil; R2 = R0 + 5% palm oil; and R3 = R0 + 5% kapok seed oil. The result showed that supplementation of 5% vegetable oil did not affect (P>0,05) the rumen pH, A/P ratio, and efficiency of energy conversion. The total VFA, acetate, propionate, butyrate, methane and NH3 was higher (P<0,05) in supplementation of 5% vegetable oil than he control. The population of protozoa, microbial protein, in vitro dry matter digestibility (IVDMD), organic matter digestibility (IVOMD), and crude fiber digestibility (IVCFD) was lower (P<0,05) in supplementation of 5% compared to the control. Population of protozoa decreased until 58,76% for R1; 66,89% for R2; and 43,33% for R3. It can be concluded that supplementation of 5% vegetable oil decreased the population of protozoa, increased the production of VFA and NH3. Supplementation of 5% kapok seed oil resulting the highest of total VFA, acetate, propionate, butyrate and NH3 among other treatments.

The aim of this study was to evaluate the effects of the inclusion of palm kernel oil (PKO) in a lamb diet on nutrient intake, digestibility, ingestive behavior, nitrogen balance, blood metabolites, rumen fermentation parameters, and animal performance. Three experimental trials were conducted. The treatments consisted of varying levels of PKO included in the diet, with PKOzero = no PKO inclusion, PKO1.3 = 1.3% addition, PKO2.6 = 2.6% addition, PKO3.9 = 3.9% addition, and PKO5.2 = 5.2% addition, based on the total dry matter (DM) of the diet. With the inclusion of PKO in the diet, linear decreases in DM (p < 0.001), crude ash (p < 0.001), crude protein (CP) (p < 0.001), neutral detergent fiber (NDF) (p < 0.001), nonfibrous carbohydrate (NFC) (p < 0.001), and total digestible nutrient (TDN) (p = 0.021) intake were observed, as was an increase in ether extract (EE) intake (p < 0.001). The digestibility coefficients of NDF and NFC were not affected by PKO addition to the diet. However, the digestibility of DM (p = 0.035), EE (p < 0.001), CP (p < 0.001), and TDNs (p < 0.001) increased when PKO was added to the lambs’ diet. Reductions in N intake (p < 0.001), fecal nitrogen excretion (p < 0.001), and microbial protein production (p < 0.001) were noted with increasing PKO levels. Serum cholesterol increased (p < 0.001) while serum GGT enzyme concentrations in the blood decreased (p = 0.048) with increasing PKO levels. PKO addition had no effect on total weight gain and average daily gain; however, feed conversion improved (p = 0.001) with increasing PKO levels. The intake, digestibility, ingestive behavior, and growth performance of lambs with PKO1.3 added to their diet were similar to animals that did not receive PKO, meaning that PKO could be an alternative energy source for growing lambs because it does not harm animal performance and can lower the cost of feed.
