Effect of unconventional oilseeds (safflower, poppy, hemp, camelina) on in vitro ruminal methane production and fermentation
Open accessAbstract
Abstract BACKGROUND Dietary supplementation with oilseeds can reduce methane emission in ruminants, but only a few common seeds have been tested so far. This study tested safflower ( Carthamus tinctorius ), poppy ( Papaver somniferum ), hemp ( Cannabis sativa ), and camelina ( Camelina sativa ) seeds in vitro using coconut ( Cocos nucifera ) oil and linseed ( Linum usitatissimum ) as positive controls. RESULTS All the tested oilseeds suppressed methane yield ( mL g −1 dry matter, up to 21%) compared to the non‐supplemented control when provided at 70 g oil kg −1 dry matter, and they were as effective as coconut oil. Safflower and hemp were more effective than linseed (21% and 18% vs. 10%), whereas the effects of poppy and camelina were similar to linseed. When methane was related to digestible organic matter, only hemp and safflower seeds and coconut oil were effective compared to the non‐supplemented control (up to 11%). The level of methanogenesis and the ratios of either the n ‐6: n ‐3 fatty acids or C 18 :2 : C 18 :3 in the seed lipids were not related. CONCLUSION Unconventional oilseeds widen the spectrum of oilseeds that can be used in dietary methane mitigation. In vivo confirmation of their methane mitigating effect is still needed, and their effects on animal performance still must be determined. © 2017 Society of Chemical Industry

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
