Effect of Different Levels of Red Sumac Powder Rhus Coriria L. on Productive Performance, Coefficient of Digestion And Some Rumen Fluid Characteristics of Awassi Lambs Females

Abstract

The main aim of this study is to find out the effect of adding different levels of sumac powder in the diets of female Awassi lambs. The field experiment lasted three months, in which 12 female Awassi lambs were used at the age of 4 months with a weight rate of (16.48 ± 1.39) kg, and distributed randomly into 4 treatments at a rate of 3 replicated / treated females The experimental animals were fed individually in cages with dimensions of 2.5 * 1.5 The animals of the first treatment (T1) were fed on a diet without adding 0% of sumac powder, the second treatment (T2) were fed on a diet with 1% sumac powder added to it The third (T3) I was fed on a legume plus 3% sumac powder, the fourth treatment (T4) I fed it on a leech with 5% sumac powder added to it. The results showed that there were no significant differences between the transactions in growth rates, including the final weight as it was limited between (23.14 - 23.84) kg and the rates of increase and the rate of daily weight gain (104, 98, 102, 102) g / day for the four treatments, respectively. As for the feed conversion efficiency, it reached (6.2, 6.4, 6.2, 6.1) kg of feed / kg increase in live weight, respectively. The results also indicated a significant improvement (P<0.01) in the material digestibility factor with an increase in the level of sumac powder, it reached (75.44, 78.17, 79.77, 82.68%) and the organic matter reached (76.95, 80.47, 82.02, 84.50)%, and the protein digestibility factor reached (73.63, 75.10, 76.79, 79.22%), and in the digestibility factor of ether extract, and that this improvement was in line with the increase in sumac powder level, as it reached (61.61, 63.95, 68.08, 70.09)% for the four treatments respectively. Whereas, the results indicated that there were no significant differences in a number of rumen fluid characteristics, including pH values, ammonia concentration, protozoa numbers and bacteria numbers.
