Three year long research of production losses (2002–2004) was conducted in pheasantries „Vinik“ (Pheasantry I) and „Rit“ (Pheasantry II). In both pheasantries, chicks would spend first nine days of life in batteries. From there they would be transferred in the pheasantry „Vinik“ into barns with outlets, where they would remain until twenty days of age, and in the pheasantry „Rit“ in stalls with outlets, where they would remain until twenty-five days of age. After that the pheasant chicks were released into rewilding pens. Monitored parameters were mortality in the breeding flock, percent of hatched eggs with respect to the amount of set eggs and mortality of chicks. Larger mortality of adult individuals from the breeding flock and lesser percent of hatched poults were established in the „Vinik“ pheasantry. Unfavorable conditions in the „Rit“ pheasantry resulted in net losses of chicks up to 40 days of age to be, depending on the year, 8.33% – 13.39%, whereas losses in the „Vinik“ pheasantry were significantly smaller and were 3.60%–4.74%. Additional improvement in production results in both „Vinik“ and „Rit“ pheasantries through application of certain modifications and improvements would be obtained.
