Methods to prevent ketosis or minimize the effects of ketosis in ruminant animals are provided. This methods include feeding to the animal biotin in combination with a mixture of at least two essential oil compounds selected from the group consisting of thymol, eugenol, meta-cresol, vaniline and guajacol. The methods usefully prevent and/or inhibit ketosis of calving ruminant animals and the subsequent need for veterinary treatment. In a preferred embodiment of a feeding concept for dairy cattle, especially calving dairy cattle, biotin is used in an amount sufficient to provide a daily dosage of 10 mg to 20 mg per head to which it is to be administered. It is at present contemplated that the essential oils are administered in amounts (total dosage ranges of essential oils) of 1 to 1.5 g per head per day.

Use of biotin and natural essential oils for bovine animals for the prevention and treatment of ketosis

The present invention is made for the prevention of ketosis or minimizing the effects of ketosis in ruminant animals. This purpose is achieved by feeding to the animal biotin in combination with a mixture of at least two essential oil compounds selected from the group consisting of thymol, eugenol, meta-cresol, vaniline and guajacol. The present invention is useful because it is capable of preventing and/or inhibiting ketosis of calving ruminant animals and the subsequent need for veterinary treatment. In a preferred embodiment of a feeding concept for dairy cattle, especially calving dairy cattle, biotin being used in an amount sufficient to provide a daily dosage of 10 mg to 20 mg per head to which it is to be administered. It is at present contemplated that the essential oils are administered in amounts (total dosage ranges of essential oils) of 1 to 1.5 g per head per day.

The invention relates to the use of at least one bacterial amylase in combination with a mixture of at least two essential oil compounds selected from the group consisting of thymol, eugenol, meta-cresol, vaniline and guajacol in feed for ruminant animals of the subfamily Bovinae for improving weight gain, milk yield and/or Feed Conversion Ratio (FCR). Examples of bovine animals are beef cattle and dairy cows.

Method for improving feed digestibility in bovine animals

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 antibiotic 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.
