Abstract :

The quality and quantity of the nutrition of dairy cattle affects their productivity, health and reproduction. As a consequence it is an important profit driver. Hence, the assessment of the quality of nutrition is a very important task for anyone dealing with dairy cattle. The most commonly used method of assessment of the adequacy of nutrition is by taking representative samples and carrying out a nutritional (feed) analysis. From the variety of approaches to assessment ├ó┬?┬?cow signs├ó┬?┬? which are behavioral, physiological and management parameters that can be observed and measured without instrumentation and laboratory analyses will be discussed. The important cow signs related to nutrition include signs related to the general condition of cattle (e.g., mentation and hair coat, body condition score), behavioral signs related to feeding (e.g., appetite, thirst, prehension and rumination) and physiological parameters related to feeding (rumen fill, fecal score and fecal digestibility scoring). The interpretation should be based on the current best evidence-based information. Diagnosis of a problem is therefore based on establishing a farm profile of cow signs. Routinely collected herd data, such as milk production and composition, nutritional analysis, fertility indexes and body condition scoring records will be discussed. Their potential value in estimating nutrition is recognized and but they are already elaborated elsewhere. The intention of this workshop is to provide practitioners, nutritional consultants and scientists and/or clients with an additional toolbox that can be used in assessment of the nutrition of dairy cattle.
