<p>In the practice of the feeding that food admixed from starting substances possessing different parameters concerning the inner contents has been considered optimal which is of the minimum specific costs between appropriate composition limits on the basis of certain theoretical considerations and practical experiences. In the complete course of the farm animal keeping, particularly in the case of monogastric animals, the optimum fodder forming is not the cheapest fodder but that fodder possessing the possible maximum biological value for a minimum price. According to the invention on the basis of the established demand data of the farm animals the optimum quantity and ratio of the essential amino acids being in the fodder mixture and to be attained for the animals have to be found so that at the same time the other parameters concerning the inner contents of the traditional fodder optimization have to be taken into account, too. One difficulty of a quick establishment of the optimum fodder composition is the fact that a laboratory determination of the composition of the fodder basic substances is slow and complicated, often it is not possible due to the conditions in the mixing plants, according to the invention such an apparatus is suggested which on the basis of the near infrared measurements directly determines important data concerning the inner contents, corrects the data stored in the data bank with these data after an appropriate check and setting from these data determines the optimum composition.</p> |
