Abstract


The objective was to describe farm conditions and production methods in intensively reared flocks of Chios sheep in Greece. The total of 66 farms of the Chios sheep Breeders Cooperative "Macedonia" were included in the study that was carried out using a purpose-built questionnaire and farm visits for onsite assessment by an experienced veterinarian. A detailed databasewas constructed using the information obtained from individual farms. Thereafter, four parameters concerning structural and management components were selected (flock size, sheep breeding experience, pasture use and application of three milkings daily) and their effect on milk production was estimated using one-way ANOVA. The results showed that the average flock comprisedof 314 sheep (16 rams, 210 ewes and 88 lamb ewes), whereas flock size was positively correlated to milk production (P<0.05). Inaddition, large flocks had more personnel and practiced three milkings per day (P<0.05). The majority of farms (83.3%) had milking parlours and the average milk yield per ewe was 276.6±55.6. The majority of farmers were relatively young (41.2±8.9years old) with limited experience in sheep production. However, they had a good level of education and showed increased interest in intensification and specialization of production methods. The acreage of private land was generally small (7.6 hectares) and was used mainly for production of feedstuffs; grazing was a secondary objective. In most farms, the feeding management wasinappropriate; overfeeding of concentrates and unbalanced rations was the dominant practice. Preventive measures included vaccinations (100% of farms vaccinated for clostridial diseases) and anthelminthic treatments (at least once a year in all flocks). In conclusion, farm conditions and production methods in studied flocks were considered satisfactory and revealed the potential for further improvements that are discussed here.
