| Abstract | ||
| This study was conducted in one of the fields in the civil hand at Alnser district north of Dhi-Qar province, for the period from 01/07/2016 until 28/09/2016. A total of 12 Arabi male lambs were used, with average age of 5.5 months and mean body weight of 21.20 ± 1.330 kg. Lambs were distributed randomly into 4 lambs/ nutrition treatments and made their diets on the basis of 3% of body weight. Three treatments were used as follows: Treatment-1- control treatment (diet concentrated). Treatment-2- fed on 90% of the control group and 10% of ground date pits substituted for the barley. Treatment-3- lambs fed on the ration of treatment2 with addition of 3 grams of bakery yeast (Saccharomyces cerevisiae) / Kg of feed which lasted for 90 days to find out the effect of replacing 10% of the date pits crush substituted for the barley with or without addition of Saccharomyces cerevisiae. There were significant differences (P<0.05) for treatment 3 which recorded in the final body weight and total gain weight and daily weight gain and feed consumption and the best feed conversion ratio in comparison with control treatment, but it's not different from the second treatment in the daily weight gain and feed consumption. Also there were significant differences (P<0.05) for treatment 3 which recorded in the average of all the characteristics of studied wool for the three months experimental represented in the raw wool weight and the clean wool weight and the length of a tuft of wool and the length of the fiber. While obtain a significant decrease in diameter of soft fiber as well as in coarse fiber diameter in comparison with control treatment, but it's not different from the second treatment in all characteristics of wool. | ||
