Abstract
This is the first scientific study for investigating and describing relationships among some lactationcharacteristics and environmental factors influencing lactation milk yield of Zom sheep in Turkey. The researchwas carried out in Çınar County in the distric of Karacadağ surrounded by Diyarbakır, Şanlıurfa and Mardin provinces.A total of 309 completed lactations belonging to 303 Zom ewes in three flocks for the years 2010 and 2011were included in the analyses. Overall means (±SE) of lactation milk yield (LMY), lactation length (LL) and averagedaily milk yield (ADMY) were 171±1.8 days, 130±2.2 kg and 770±22.7 g, respectively. LL was significantlyaffected by year, flock and lambing season (P<0.05) while LMY and ADMY were significantly affected by flock,lambing season and parity (P<0.05).It was concluded that the matings should be arranged so that the lambings occur in month(s) closer to spring seasonin order to increase LMY by means of having ewes taken benefits of fresh pasture. Milk yield records in the firstthree months of lactation can be used to predict LMY and be used as an early selection criteria for increasing LMY.
