Abstract

This study was under taken to find out affecting of age and sex on wool quality of LORI SHEEP breed. in the first research, 192 wool sample of sheep were collected at shearing season in Lorstan province. Sheep were selected under uniform condition of management from flock of LORI SHEEP. The shearing was taken for these animals to determine body weight on the time of shearing, FLEECE WEIGHT, STAPLE LENGTH, FIBER DIAMETER, FLEECE FAT and CLEANED WOOL YIELD in LORI SHEEP breed. An age of animals was among 1to 4 years. The statistical analysis of data was carried out with factorial experiment basis on completely randomized design combined with two factor age and sex over two years. The body weight on the time of shearing was covariate variable. The mean of FLEECE WEIGHT, STAPLE LENGTH, FIBER DIAMETER, cleaned wool, greasy fleece were 2.21±0.22kg, 9.47±1.75cm, 31.67±4.19 micron, 72.51%±8.91% respectively. The investigation indicated that the mean of FLEECE WEIGHT and STAPLE LENGTH were more in female and CLEANED WOOL YIELD was in male more percentage. Effect of age and sex were measured on five parameters. Effect of year on STAPLE LENGTH and interaction effect between sex and age on FIBER DIAMETER were significance. According to this investigation an increasing in the diameter was observed with the advance age. The results indicated that LORI SHEEP wool has to tender relatively comparison with the other native sheep breeds of Iran.
