A protein fraction and an oxidation stable fat fraction are recovered from meat trimmings. The trimmings are comminuted, mixed with a food grade acid at pH 3.6 to 4.4 to form a liquid protein fraction and a solid fat fraction. The liquid fraction is mixed with a food grade alkali to precipitate the protein. A myoglobin rich fraction is recovered from the protein fraction and mixed with the precipitated protein.

Disclosed are a fish protein oligopeptide with low allergenicity and slight fishiness, and industrial preparation method and application thereof. The method comprises the following steps: 1) washing fresh fish flesh and/or fish wastes, crushing, and adding water to obtain a mixture; 2) performing thermal denaturation on the mixture to obtain a denaturized protein solution; 3) centrifuging the denaturized protein solution to obtain a precipitate, and adding water into the precipitate and grinding, to obtain a slurry; 4) adjusting the slurry to pH 6-9, and sequentially adding a neutral protease, a papain and an alkaline protease to conduct enzymolysis, and after enzyme inactivation, to obtain an enzymatic hydrolysate; 5) centrifuging the enzymatic hydrolysate, and performing membrane filtration on centrifuged supernatant, to obtain the fish protein oligopeptide with low allergenicity and slight fishiness. The method completely eliminates the allergenicity and fishiness of fish proteins, and prevents release of bitter components.

The present disclosure provides compositions and methods for improving reproductive health of mammals and increasing milk production from female mammals. The methods involve administering an effective amount of IL-8 to a female mammal such that the reproductive health of the mammal is improved, or milk production from the mammal is increased, or the fat content of the milk is increased. In another aspect the disclosure includes prophylaxis and/or therapy of uterine conditions by administering IL-8 to a female mammal.
