摘要:
The present invention provides a combination of antioxidants that effectively stabilize different types of fats utilized in a ruminant diet. When included in a ruminant feed ration or water source, the antioxidant combination typically increases nutrient digestion, such as fiber and protein, improves rumen fermentation, improves microbial growth, improves microbial efficiency, increases milk production and/or milk fat, improves antioxidant status of the ruminant, and attenuates the negative effects of some fats in the ruminant animal.
摘要:
Disclosed are marine coating compositions that are useful to inhibit the fouling of a marine structure by a broad spectrum of organisms. Generally the marine coating compositions comprises an antifouling agent and an organic vehicle. Figures IAlC depict photographic images illustrating the antifouling activity in copper ablative paint of (A) a negative control, (B) 5% HMTBA-Cu and (C) 5% HMTBA-Zn, respectively.
摘要:
A method is disclosed for determining the viability of sporocyst-forming protozoa. The method involves treating a sample of protozoa with at least one vital dye and determining the viability of the protozoa in the sample by differential staining. The viability of protozoa in the sample can then be correlated with the viability of protozoa in the population from which the sample was obtained.
摘要:
A continuous process for the preparation of 20hydroxy-4-methylthiobutanoic acid or a salt thereof which includes introducing an aqueous mineral acid into a nitrile hydrolysis reactor including a continuous stirred tank reactor and introducing 2-hydroxy-4-methylthiobutanenitrile into the nitrile hydrolysis reactor. 2-hydroxy-4-methylthiobutanenitrile is continually hydrolyzed within the nitrile hydrolysis reactor to produce a reactor product stream containing 2-hydroxy-4-methylthiobutanamide. This product stream is continuously introduced into an amide hydrolysis flow reactor. 2-hydroxy-4-methylthiobutanamide is continually hydrolyzed within the amide hydrolysis flow reactor to produce an aqueous hydrolyzate product containing 2-hydroxy-4-methylthiobutanoic acid which is recovered
摘要:
A process for formulating a ruminant food ration in which the methionine needs of the ruminant are determined, a plurality of natural or synthetic feed ingredients and the nutrient composition of each of said ingredients are identified wherein one of said ingredients is 2-hydroxy-4- (methylthio)butanoic acid or a salt, amide or ester thereof, and a ration is formulated from the identified feed ingredients to meet the determined methionine needs of the ruminant which comprises one or more grains, a hydroxy analog of methionine, and optionally a bypass fat wherein (i) the hydroxy analog of methionine is selected from the group consisting of 2-hydroxy-4- (methylthio)butanoic acid and the salts, amides and esters thereof, (ii) the hydroxy analog of methionine is added separately from any bypass fat which is included in the ration, and (iii) the ration is formulated on the basis that at least 20 % of the hydroxy analog of methionine is assumed to be available for absorption by the ruminant.
摘要:
The system and method include a fleet of vehicles to provide material to a plurality of tanks at various customer locations. An inventory indicator associated with each of the tanks provides a quantity signal to the central station indicating the quantity and temperature of each of the tanks. A processor at the central staiion monitors the quantity signals of each of the tanks to determine past usage rates of the contents of each of the tanks. The processor projects future tank quantities based on the past usage pattern and determines possible routes for each of the vehicles to each of the tanks. The processor optimizes the routes, delivery amounts, and delivery schedule to minimize total delivered cost for the products based on the projected future tank levels and the possible routes to dispatch each of the vehicles.
