The exhibited majority lambs’ since lambs born from aged 4 years gave more values than those less years. Sex had also contributed measurements higher collected males females BH, month-6 BL, RH). Time birth yielded significantly better for January other months. However, December lambs. In conclusion, this demonstrated obvious measured.
