Abstract

Lawsonia inermis is one of the drought-resistant plants in the southern of Iran and contains a large number of antibiotic-like compounds and phenolic compounds such as tannins. This study was conducted to determine nutrients composition, Total phenolic and tannin contents and some fermentation parameters of Lawsonia inermis leaves via in vitro gas production technique. The leaves samples were randomly collected from six farms, air-dried and ground. Nutrients composition, total phenolic and tannin contents of samples was measured. The degradability kinetic of samples was determined via in vitro gas production method. The gas production was recorded at 2, 4, 8, 12, 24, 36, 72 and 96h of incubation. The results showed that crude protein, crude fat, neutral detergent fiber (NDF), acid detergent fiber (ADF), crude ash, calcium and phosphorous concentrations of samples were respectively 13.97, 0.18, 15.98, 3.17, 0.98, 0.08 and 0.01 percent. Additionally, total phenolic and tannin contents of the samples were 33.49 and 13 percent respectively. The amount of gas production was 55.3 ml. The fractional rate of gas production was 0.078/h. The organic matter digestibility of lawsonia inermis leaves
was 61.83%. Totally, it can be concluded that due to its low neutral and acid detergent fiber and appropriate crude protein and organic matter digestibility, lawsonia inermis leaves can be fed to ruminant animals.
