RESEARCH ON PERFORMANCES OF RAISING CERTIFICATE CHICKENS

Abstract

The important demand for non-pollutant eco-agrifood products, with a reduced level of harmful influence on human health, requires increasing concern for the production, management and marketing of agricultural products (poultry included), obtained under ecological conditions.The research presented in this paper is also related to this context, both by settling the qualitative and quantitative features of eco-chickens and a likely decrease of production costs by varying the values of energy and protein within the mixed fodder structure used for these chickens.Our research was performed on 150 birds (Ross 308) at SDE Avicola Moara Domnească farm during a 56 days’ period. The birds were distributed in three treatment groups according to three nutritive values of mixed fodder (CM, C1, C2). Following result processing, we found that the best weight gain was recorded in CM group (a daily average gain of 41.98 ± 0.91 g). The lowest value for the specific consumption was recorded in CM group (2.54 ± 0.16 kg, very significant differences between the groups) and the lowest viability was recorded in C1 group (10.40 ± 1.56 %).
