A method of calibrating a sensors in a system for obtaining animal data from animals is described. The sensors are configured to obtain measurements of an animal related parameter during arbitrary visits by the animal to the sensors. For at least one of the animals, a first measurement associated with a first sensor of the sensors is obtained, and calculating one or more relations between the first measurement and one or more second measurements associated with the respective animal. Each of the second measurements is obtained using a further sensor, so as to obtain at least one representative relation for each combination of the first sensor and each one of the further sensors. The system calculates, based on the at least one representative relation, a correction factor associated with at least one sensor of the plurality of sensors.

A method for analyzing milk is disclosed in which method light is introduced into milk and signals resulting from a reflectance measurement, from a transmittance measurement, and from an unscattered transmittance measurement are obtained. The signals may be electronically processed to output information indicative of at least one parameter of the milk. In embodiments, a method for analyzing content of carbohydrates in milk includes introducing light into the milk and analyzing light signals from the milk, wherein the wavelength of the light is not more than 2500 nm, and a device for analyzing milk, which has a first measuring length for measuring transmittance of light through the milk and reflectance of light by the milk, and a second measuring length for measuring unscattered transmittance of light through the milk, wherein the second measuring length is thinner than the first measuring length by a factor of at least 10.

In some aspects, the disclosure relates to compositions and methods useful for the diagnosis and treatment of neurodegenerative diseases, such as leukodystrophies (e.g., Canavan Disease). In some embodiments, the methods comprise administering to a subject an N-acetylaspartate (NAA)-depleting agent or an N-acetylaspartate (NAA)-depleting agent based upon the subject's metabolic profile.
