Definitions

  • the present invention relates to the field of reduction of methane emission in ruminants. Particularly, it relates to the use of a feed composition or a feed additive comprising at least one fatty acid containing at least 5 carbon atoms and at least one organic molecule substituted at any position with at least one nitrooxy group, for reducing the production of methane emanating from the digestive activities of ruminants, and/or to improve the ruminant performance.
  • the present invention further relates to animal feed or animal feed compositions and feed additives comprising the above-mentioned molecules.
  • feed or feed composition means any compound, preparation, mixture, or composition suitable for, or intended for intake by an animal.
  • a ruminant is a mammal of the order Artiodactyla that digests plant- based food by initially softening it within the animal's first stomach, known as the rumen, then regurgitating the semi-digested mass, now known as cud, and chewing it again. The process of again chewing the cud to further break down plant matter and stimulate digestion is called "ruminating”.
  • Methane is produced as a natural consequence of the anaerobic fermentation, which represents an energy loss to the host animal.
  • Carbohydrate makes up 70 to 80 % of the dry matter in a typical dairy cattle ration and in spite of this the absorption of carbohydrates from the gastro-intestinal tract is normally very limited. The reason for this is the extensive fermentation of carbohydrates in the rumen resulting in production of acetate, propionate and butyrate as the main products. These products are part of the so called volatile fatty acids, (VFAs).
  • VFAs volatile fatty acids
  • methane is also a greenhouse gas, which is many times more potent than CO2. Its concentration in the atmosphere has doubled over the last century and continues to increase alarmingly. Ruminants are the major contributors to the biogenic methane formation, and it has been estimated that the prevention of methane formation from ruminants would almost stabilize atmospheric methane concentrations.
  • Antibiotics and more particularly ionophores have been shown to slightly reduce methane production in ruminants (Guan et al. 2006. Journal of Animal Science; 84: 1896-1906).
  • the effect of antibiotics on the formation of methane has some disadvantages because of rapid adaptation of the microflora and/or resistance development leading to a complete loss of the intended effect within a short period of time (2 to 3 weeks), and because the use of antibiotics is banned in Europe for non- therapeutic use.
  • Non-antibiotic products leading to reduction of methane emission, when tested using an in vitro rumen simulation model, have recently been published (WO 2010/072584).
  • WO 2010/072584 the amount required to produce a moderate reduction of methane emission are not compatible with the ruminant feed industry cost constraints.
  • compositions specified herein after have a great potential for use in animal feed in order to essentially reduce the formation of methane without affecting microbial fermentation in a way that would be detrimental to the host animal.
  • compositions of the present invention also have a great benefit regarding overall animal performance as measured by ruminal acetate/propionate ratio. Said compositions are also more stable than those described in the prior art, safer for the animal and human, and they are active at very low concentration in the rumen.

  • Sample weighing The feed stuff is sieved to 1 mm - usually TMR (44 % concentrate, 6 % hay, 37 % maize silage and 13 % grass silage) - and weighed exactly into 64 syringes. 4 of these syringes are the substrate controls, which display the gas production without the ef- feet of the tested compounds. 4 other syringes are positive control, in which bromoethane sulfonate has been added to 0.1 mM. When needed, 4 syringes contain a carrier control (if the test compounds need a carrier). The remaining syringes contain the test substances, by groups of 4 syringes.
  • TMR 44 % concentrate, 6 % hay, 37 % maize silage and 13 % grass silage
  • the components are mixed in a Woulff bottle in following order:
  • the completed solution is warmed up to 39 °C followed by the addition of 1 .83 ml sodium salt solution and the addition of reduction solution at 36 °C.
  • the rumen liquor is added, when the indicator turns colourless.
  • Extraction of the rumen liquor 750 ml of rumen liquor are added to approximately 1 ,400 ml of medium solution under continued agitation and C02-gassing.
  • the diluted rumen fluid (24 ml) is added to the glass syringe.
  • the syringes are then incubated for 8 hours at 39 °C under gentle agitation. After 8 hours, the volume of gas produced is measured, and the percentage of methane in the gas phase is determined by gas chromatography.
  • the food fermented was artificial TMR (44 % concentrate, 6 % hay, 37 % maize silage and 13 % grass silage).
  • Laurie acid from Sigma Aldrich was used at a concentration of 1000 ⁇ .
  • 3-Nitrooxy-propanol (3-NOP) was used at two different concentrations, 2.5 ⁇ and 5 ⁇ .

Abstract

La présente invention concerne le domaine de la réduction des émissions de méthane chez les ruminants. Plus particulièrement, l'invention concerne l'utilisation d'une composition alimentaire pour animaux ou d'un additif pour l'alimentation animale comprenant au moins un acide gras contenant au moins cinq atomes de carbone et au moins une molécule organique substituée au niveau de n'importe quelle position par au moins un groupe nitrooxy afin de réduire la production de méthane provenant des activités de digestion des ruminants, et/ou d'améliorer le rendement des ruminants.
