Effect of adding Damsissa (seeds or leaves) (Ambrosia Maritima L.) to sheep diets on its productive performance [electronic resource].

Includes references.

Two experiments were conducted to study the effects of supplement Damsisa leaves or seeds (Ambrosia maritima L or Artemisia absinthium) diets on growing lambs performance. First experiment was carried out to determine the in-vitro disappearance of dry matter (IVDMD) to find out the best levels of Damsisa leaves and seeds supplementation (from 0.5 to 4% of DMI) that could be applied in feeding and in-vivo digestibility trials. Depending on the results of the first experiment, fifteen growing Barki cross breed lambs of 5 months old and 23.3 kg average live body weight were randomly assigned into 3 similar feeding groups (5 animals each) to fed one of the experimental diets. All diets consisted of 50% roughage (20% berseem hay + 30% rice straw) and 50% concentrate feed mixlure (CFM) without Damsisa (D1 control diet), + 2.5% Damsisa leaves as a replacement of DMI. (D2 diet) and 2.5% Damsisa seeds as a replacement of DMI (D3 diet). Diets were formulated to cover maintenance and growth requirements of the growing lambs according to NRC, 1994.
