dc.description.abstract | In the opinion of many authors (Van Dieoen et al., 2007; Petrović et al 2016,
2017, Yilmaz et al., 2016), the current state-of-the-art technology of farm
systems in livestock breeding represents an obvious risk to biodiversity and
its ecological sustainability. On the other hand, despite this conclusion, the
consumption of meat and milk is growing. The growing knowledge of
ecosystem disorders and the threat of the living world in its entirety imposed
a need to re-examine the technologies and methods so far that have been
used to accelerate productive growth in all human activities, including
agriculture. It began to study the influence of various external factors on
animal productivity (Petrović I sar, 2011, 2015). Rodrigez et al (2017)
launched a project that will assess the sustainability of the various European
sheep production systems, focusing on the ecological aspect of animal
welfare and the nutritional value of lamb. Preservation of native races for use
in organic systems is important and can stop the extinction of races. Unique
characteristics of domestic breeds can help farmers and scientists to preserve
biodiversity and ecology in the future (Nauta, 2006, Petrović et al., 2013). | sr |
