Influence of turmeric and geranium sanguineum supplementation on Clarcs of energy distribution/protein transformation in laying hens

Dimo Penkov, Svetlana Grigorova

Abstract: A comparative study of the influence of biologically active additives Geranium sanguineum and
turmeric (Curcuma longa) on the energy and protein transformation in the eco-technical chain “feed
– egg mélange” in laying hens from Lohman Klassik Brown breed was conducted. Newly introduced
selection-technological-ecological indicators were used in the present research: “Clarc of energy
distribution” (CED) and “Clarc of protein transformation” (CPT).
The CED from feed to egg mеlange is higher for the control group (0.2147), compared to the group
with added Geranium sanguineum (0.2098) and turmeric (0.2114).
CPT from feed to the egg mеlange is with highest value for the control group (0.2668), followed by
the group received Geranium sanguineum (0.2549) and turmeric – 0.2547.
Although the differences are not statistically significant, there is a trend that the addition of 0.05%
blood geranium and 0.5% turmeric to compound feeds for laying hens has a rather negative effect on
energy distribution and on protein transformation.
