Animals and data: Greasy wool yield records of Buchi sheep maintained at the Livestock Experiment Station Jugaitpir Bahawlpur District Punjab Pakistan between1986 and 2010 were used for this study.
Statistical analysis: Greasy wool records collected from 1986 to 2010 were used to estimate the effects of year of birth season of birth sex of lamb type of birth parity of dam age of dam at lambing weight of dam at lambing and two way interactions between these factors on greasy wool yield traits.
Data description: Descriptive statistics for greasy wool traits are presented in Table 1.
Environmental factors affecting greasy wool yieldtraits greasy wool yield at 1 shearing: The analysis of variance to estimate the effects of different environmental factors and interactions between these factors on greasywool yield at 1 shearing is presented in the Table
Male lambs generally attained higher weights and were likely to be heavier and of larger size than females at preweaning ages thus produced more greasy wool at first shearing.
(1993) for Awassi Baber (1994) and Iram (2008) for Lohi and Akhtar (1996) for Hissaredale breeds of sheep reported that year of birth and sex of lamb were the main sources of variation for greasy wool yield at 1st shearing.
On the other hand Hussain (2006) reported year of birth as well as sex of lamb and age of dam was significant for Thalli sheep in Pakistan.The significant Kari sheep breed in Pakistan also recounted that sex of lamb was the main source of variation for the greasy wool yield at 1st shearing.
``The reputation for British wool internationally was damaged through foot-and-mouth disease and the Chinese market, the largest global consumer importing 12.5pc of the greasy British clip in 2000, is still closed to greasy wool
