    摘要: A process for the preparation of a sample to be tested by immunological assay for detecting serum gonadotrophin in blood of mares, for the purpose of diagnosing the mares pregnancy, which comprises adding an acid selected from the group consisting of sulfosalicyclic, perchloric, and metaphosphoric acids, to the blood, plasma, or serum of the mare to be diagnosed, at a concentration of at least 0.15 m-mol based on 1 ml of serum but below the saturation concentration, separating the resultant precipitate and recovering the supernatnat liquid, and a method diagnosis of pregnancy of a mare using such test sample.

    摘要: Shown here is a process for preparing a concentrated liquid composition (such as a broth) from poultry or other meat sources without the use of any enzymes. The resultant composition may have high content of solids but are pumpable or pourable and have relatively long shelf life at room temperature. Also shown are methods of extracting proteins from raw poultry or other meat sources at relatively low temperatures. Methods of making a high protein curd is also shown.

    摘要: The invention relates to a method for producing blood meal comprising the subsequent steps of (i) providing an aqueous mixture comprising raw blood, preferably having a solid content of between about 5 and about 18 wt %, and (ii) increasing the solid content of the mixture to obtain a mixture having a solid content of about 20 wt % or higher, preferably between about 20-80 wt % and (iii) concurrently drying and grinding the resultant mixture in an air turbulence mill, to obtain blood meal having an average particle size (d50) between 20 μm and 0.7 mm, a d90 of below 1 mm as measured with laser diffraction using a dry powder Beckman Coulter particle size analyzer, and an ileal digestibility of about 85% or higher preferably of about 87% or higher, and more preferably about 90% or higher. The invention furthermore relates to a coagulated blood meal product with high ileal digestibility.

    摘要: Example embodiments provide an apparatus that is useful for recycling protein waste and producing fuel from protein waste. Waste is ground by a grinding means and digested by a enzyme digest medium composed of enzymes, preservatives, inedible egg and or a waste fluid that may include other protein sources with or without fat. The ground proteins are digested with the enzyme in recirculated digest tanks. Fat can be collected from the tank by addition of acid and separation of fat from water with a centrifuge. Alternatively the ground protein and enzyme can be fermented and gas collected from the digest tank in a pressure tank with a compressor. The protein solubles are emulsified, separated from water, and extruded before drying. Either fat or gas can be used to fuel a dryer. Example embodiments provide a highly digestable paletable food stuff from protein waste which is usable for pet, livestock, or an aquaculture diet.
