Energy and protein net utilization in the chain "feed-meat" in rabbit’s fattening trough the introduction of the “Clarc energy distribution/Clarc protein transformation” system

Abstract

Using specific original indexes “Clarc of energy/protein distribution/transformation” the energy and protein transformations in the eco-technical chain “fodder –pure meat (edible parts)” by the 2-nd period of fattening of rabbits have been calculated. Data from real experiments with New Zealand white rabbits have been used. The following results have been reported: Clarc energy distribution (digestible energy in fodder –gross energy in meat) -0.1877 or 18.77%; Clarc of protein transformation (crude protein in fodder –crude protein in meat) -0.3818 or 38.18%.The proposed “Clarcs” can be used in at least 3 directions: Biological (most important) -for objective calculation of transformation of nutritional substances in the food pyramid; breeding-for selection of animals with higher levels of transformation of the food substances; technological -for assessment of the currently used technologies and optimization themto increase the efficiency.
