Abstract

The aim of the study was to analyse the impact of intensification factors on the economics of dairy sheep (Improved Valachian breed). The evaluated factros were: early weaning of lambs with selling (5 days of age) or with artificial rearing of lambs (to 50 days of age), out-of-seasonal lambing in autumn and reache the production parameters settled in the new breeding goal. Modelling the early weaning followed by selling of lambs was of positive impact on revenues (+4 %/ewe/year) and efficiency of the system (produktivity) was a slightly improved from 83 to 86 %, when compared to the base production system. A higher value of sold milk (157 kg/milking period) and lower production of lambs (3.45 kg of lamb/ewe/year) at weaning played the main role in this variant. Similarly, more effective utilization of costs (efficiency of 90 %) was found when the early weaning was followed by artificial rearing of lambs. In this variant, total revenues per ewe and year increased by 19 % and costs by 10 %. For out-off-seasonal lambing, a lower conception rate of ewes (-11 p. p) and production of lambs (16 kg of lamb/ewe/year) was compensated by higher market prices of sheep commodities (+11 to +20 %) received in winter season. Application of the parameters given in the breeding goal increased the revenues (+35 %) and more effective utilisation of costs was found (108 %). Early weaning of lambs followed by artificial rearing along with achieve the production parameters specified in the breeding goal can be recommended as useful intensification factors in analyzed multipurpose dairy sheep breed, all in regard to the production (especially nutrition, biological and technology) opportunities of individual farm.
