The present disclosure provides a feed additive for domesticated animals that is capable of increasing feed performance, as well as associated methods for promoting growth and zootechnical performance in domesticated animals. The animal feed additive provided contains Total Lignans standardized in the contents of Furoguaiacin-like compounds and Guaiacin-like compounds. The present disclosure also describes methods for improving growth via the dietary inclusion of Total Lignans standardized in Furoguaiacin-like compounds and Guaiacin-like compounds.

Disclosed herein in is a method of increasing plasma dileucine levels in a subject comprising administering to the subject an effective amount of a composition comprising leucine. In certain embodiments, the composition does not comprise dileucine. In certain embodiments, the amount of increase in plasma dileucine is greater than that resulting from administering a protein supplement comprising a comparable amount of leucine. In certain implementations, administration of the composition results in an increase in plasma dileucine that is from about 10% to about 50% greater than from administering a protein supplement comprising a comparable amount of leucine.

The present invention concerns a non-fatty palatability enhancer for use in cat food comprising an amino reactant having a ratio AAS/AAT of sulfur-containing free amino acids (AAS) to total free amino acids (AAT) from 1 to 12.8% by weight, and a carbonyl composition comprising more than 20% up to 100% by weight of monosaccharides and/or disaccharides and/or oligosaccharides.

Described herein are pet food compositions comprising—in relevant part—effective amounts of betaine and carnitine. Methods of making and using these compositions are also described.

The invention provides a method of treating a disorder characterised by elevated or dysregulated myostatin, disorders where the interaction between follistatin and angiogenin can be used to improve function in tissues, neurological diseases or disorders, spinal injuries or diseases, bone diseases or disorders, diseases involving glucose homeostasis, wound healing, neuroprotection, nervous system functional support or managing metabolic diseases, the method comprising administering an effective amount of angiogenin or an angiogenin agonist. Compositions and neutraceuticals comprising angiogenin are also provided.

To provide a feed that does not pollute rearing water, improves the immunity activity of leptocephalus larvae, is capable of directly feeding eel leptocephalus, and is capable of effectively inducing the growth of said larvae into glass eels. This micro-encapsulated aquaculture feed includes: an oil phase 11 having an oil-soluble nutrient component; a water phase 13 which is present inside the oil phase 11, and which includes a water-soluble nutrient component; and a film 15 which includes the oil phase 11 and the water phase 13. The water-soluble nutrient component includes at least one hydrolysate from among hydrolysates of amino acids, oligopeptides, and proteins.
