Abstract: A method for monitoring food intake of livestock animals includes defining a relationship between time an animal spends at a feeding trough and the animals food intake during that time, monitoring the time an animal spends at the feeding trough and determining a quantity of food intake for the animal based on the time spent at the feeding trough and the defined relationship. Optionally, time an animal spends in a feeding position at the feeding trough is monitored and used to determine quantity of food intake.

Abstract: A method and a system for predicting a calving date of an animal comprises monitoring a behavioral pattern of an animal, determining a given change in the behavioral pattern, and predicting the calving date responsive to the given change in the behavioral pattern.

Abstract: An NIR spectroscopy fluid analyzing system using a series of LED's, each having its own preselected center wavelength, as illumination sources. These wavelengths have overlapping spectral widths, such that the measurement covers a broad spectrum. The LED's illuminate the fluid sample sequentially, and subsequently the transmission absorbance through the sample and the reflectance or scattering from the sample is measured for the wavelength range of each LED. The measurements are performed using photodetectors. The concentrations of component parts of the fluid are expressed in the form of a polynomial, which is a function of the measured transmitted and/or reflected intensities, and of empirical coefficients, which are extracted by prior statistical analysis on measured intensities obtained from a large number of test samples having known concentrations of the component. A novel sample chamber, capable of performing optical absorption measurements on a flowing sample of fluid, is described.
