Methods and compositions are described for producing a phytase in transgenic maize plants and then incorporating parts of the transgenic maize plants in animal feed. The feed phytase enzyme displays activity across a broad pH range, and tolerance to temperatures that are often encountered during the process of preparing animal feeds. Methods of producing an animal feed that incorporate the transgenic maize plants, parts thereof or plant derived phytases, as well as methods of promoting the release of inorganic phosphate from a phytic acid in an animal, producing an animal meat, or reducing the ratio of intake of an animal feed per weight of the animal meat by feeding an animal with the animal feed incorporating transgenic maize plants are provided.

Disclosed is a method for constructing fluorescent Bombyx Mori silkworm silk irradiated by near-infrared light and its products, comprising: (1) preparing upconversion nanoparticles, and performing surface modification with concanavalin to obtain modified upconversion nanoparticles; (2) uniformly dispersing the modified upconversion nanoparticles in water to formulate an aqueous solution of the upconversion nanoparticles, (3) picking mature mulberry leaves, immersing the mulberry leaves in the aqueous solution system of the nanoparticles, leaching water, and naturally drying the mulberry leaves; (4) after silkworms have grown for a set time, feeding the treated mulberry leaves to the silkworms until the silkworms spin silk cocoons; and (5) collecting the silk, so as to obtain mulberry silk that fluoresces under near-infrared light. The present invention selects upconversion nanoparticles capable of emitting fluorescence under the irradiation of near-infrared light which has stronger penetration, thus has better application in deep tissue imaging.

The present application discloses a composition of a butyrate or a derivative thereof and benzoic acid, preparation method and use as a feedstuff additive thereof, wherein the composition comprises 5 wt % to 50 wt % of the butyrate or the derivative of butyric acid, and 50 wt % to 95 wt % of the benzoic acid or benzoate. The benzoate and butyrate dissociate into acidic molecules when they enter into animals' bodies. The butyric acid stimulates parietal cells to grown and the parietal cells produce hydrochloric acid, which thereby reduces the pH value in the stomach. Benzoic acid can inhibit facultative anaerobes such as Lactobacillus and butyric acid-producing anaerobic bacteria in the stomach, rendering the two floras become predominant microflora, and therefore produce more endogenous organic acids such as lactic acid and butyric acid. These acids are beneficial to gastrointestinal health and animal growth. As a result, a synergy effect of the two components in the composition is achieved.

Compositions, in particular compacted compositions, contain at least one betaine salt and at least one feed additive; and can be used for providing the feed additive, in particular probiotics, to drinking water or rearing water.
