The disclosure relates to compositions comprising urea particles. The disclosure further provides methods of manufacturing the urea particles and their uses.

The present invention relates to a tall oil fatty acid which is modified by saponification for use in the prevention of growth of harmful bacteria in the animal digestive tract and/or in the prevention of intestinal disorders. The invention further relates to a feed supplement and a feed composition comprising tall oil fatty acid which is modified by saponification.

A ruminant feed supplement composition including urea, biuret and one or more nitrate compounds. The present disclosure further relates to the use of such a ruminant feed supplement composition as a NPN-source to improve nitrogen nutrition and to reduce methane emissions and further to improve the efficiency of microbial protein synthesis (EMPS) by rumen microbes in a ruminant animal; and/or to decreasing the acetate to propionate ratio produced by rumen microbes in a ruminant animal; and/or to increasing the (in vitro) dry matter (DM) and organic matter (OM) digestibility; and/or to improve the average daily gain (ADG) of a ruminant animal; and/or to improve the feed efficiency of a ruminant animal.

The present disclosure relates to the use of a mixture of urea, biuret and N-containing by-products of the biuret production out of urea, as a NPN-source in a ruminant feed supplement composition (i) to reduce methane emission produced by ruminant animals, (ii) to decrease the acetate to propionate ratio produced by rumen microbes in a ruminant, (iii) to improve the EMPS, (iv) to increase the DM and OM digestibility, and/or (v) to improve the dry matter intake (DMI) of ruminant animal. The present disclosure further relates to a ruminant feed supplement composition comprising urea, biuret and N-containing by-products of the biuret production out of urea, as well as to methods of feeding a ruminant with a feed comprising said ruminant feed supplement composition.

The present invention relates to an ingredient, wherein the ingredient comprises a viable methanotroph in combination with at least one oxygen agent, and a feed product comprising the ingredient.

The present invention relates to an ingredient, wherein the ingredient comprises a viable methanotroph in combination with at least one oxygen agent, and a feed product comprising the ingredient.

The present invention relates to a new class of methanogen inhibitors for ruminants. The invention also extends to the use of such compounds in ruminants to reduce methane production in the rumen and/or to enhance productivity in the ruminant.
