The present disclosure relates to the reduction of methane production in ruminants. In particular, the disclosure relates to solid and semi-solid compositions for administration to a ruminant comprising a substance capable of inhibiting the production of methane in vivo in the ruminant. The disclosure also relates to controlled release boluses, animal licks, and animal feeds comprising solid and semi-solid compositions comprising a substance capable of inhibiting the production of methane in vivo in a ruminant. The disclosure further relates to methods of orally administering boluses capable of inhibiting the production of methane in vivo in a ruminant to ruminants and methods of orally transferring substances capable of inhibiting the production of methane in vivo in a ruminant to ruminants. In addition, the disclosure relates to viruses capable of inhibiting archaea that produce methane in vivo in a ruminant.

A suspendable feed block system for animals has a feed block formed of a hardened mass of feed supplement material in block form, wherein the feed supplement material provides a source of magnesium. The feed block is molded around and encases a feed block support. The support has an elongated flexible element including a plurality of protuberances located intermittently along a length of the element. At least one end of the elongated flexible element protrudes from the feed block and is fastenable to a separate suspending component. A method of manufacturing the suspendable feed block system for animals is also provided. A mold can be used for forming the feed block with the support suspended or encased therein, and the mold can be biodegradable, edible, or both.

The present invention concerns novel probiotic compositions that increase nitrate- and nitrite-reduction in animals such as ruminants. The present invention thus provides compositions and methods for reducing nitrate/nitrite toxicity in such animals, or prophylactically protecting such animals from the effects of toxicity, such as methemoglobinemia. A novel strain of an unspeciated bacterial strain related to Paenibacillus species with nitrate- and nitrite-reducing capabilities is described. In conjunction with nitrate-supplemented diets, the probiotics of the present invention can also be utilized to reduce methanogenesis in livestock. Furthermore, the probiotic compositions of the present invention can be used to reduce the number and kind of food-borne pathogens, such as Escherichia coli and Campylobacter jejuni.

A method of forming a low moisture block with cold flow resistance proceeds by subjecting a feed mixture containing molasses-like liquids to mixing to form a homogenous mixture; dehydrating the molasses-like mixture to less than about 2.0% moisture using heating; adding to the dehydrated molasses-like liquid mixture one or more feed ingredients in dry ingredient form, comprising 10% to 50% by weight of the resulting mixture; and adding to the dehydrated molasses-like mixture a composition comprising CaO or reactive MgO or combinations thereof, with the composition comprising 0.1% to 10% by weight of the resulting mixture. The composition is mixed in to form a homogenous mixture.

A consumption-regulated feed block for controlled consumption of animal feed, comprises a mass of controlled feed material, the consumption of which is to be controlled, in compressed block, chemical block or hybrid block form; and an intake control matrix of low moisture block material positioned in the controlled feed material and forming consumption control pockets to regulate consumption of the controlled feed material by requiring an animal to consume by licking portions of low moisture block material in order to consume controlled feed material in an adjacent consumption control pocket.

Spent bleaching earth from edible oil processing can be used in the formulation of salt and mineral lick blocks and pellets for livestock to enhance the health and nutritional value of the feed supplements. Because of the ignition hazard inherent with spent bleaching earth, landfill has been and continues to be the dominant disposal method. By adding salt or brine to the spent bleaching earth upon discharge from the process filters, the hydroscopic property will keep the material safe for handling and economic use as described.
