Abstract
Abstract: To measure the apparent digestibility of wheat straw nutrients with pomegranate pomace or chicken manure by three methods of acid-insoluble ash, acid-insoluble lignin, and total feces collection, from four male camels with an average weight of 116.25±9.35 kg and age of one year were used in a completely random design. The duration of the experiment was 42 days (two periods of 21 days), including 14 days of habituation and seven days of sampling. The experimental treatments included: 1) wheat straw with 25% pomegranate pomace and 2) wheat straw with 25% chicken manure. The results showed There is a significant difference between the two methods of acid-insoluble ash indicator and total feces collection in estimating the digestibility coefficients of dry matter, organic matter, crude fat, insoluble fibers in neutral detergent and insoluble fibers in acid detergent of wheat straw with pomegranate pomace (P>0.05). But such a difference was not observed in estimating the digestibility coefficients of wheat straw and chicken manure. The recovery percentage of acid-insoluble ash in wheat straw + chicken manure diet was 105.14±17.08. In general, it seems that due to the weak correlation between the three methods of measuring digestibility and taking into account the existing limitations, including the cost and many facilities, especially in large livestock, in determining digestibility with the method Collecting total feces and acid-insoluble lignin, the acid-insoluble ash method can be used to determine digestibility in camels.
