| Abstract |
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 mixture (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.
Results of the first experiment indicated that the in-vitro dry matter disappearance (IVDMD) was increased by increasing the level of 2.5% Damsisa leaves or seeds supplemented rations. Results of the second experiment revealed that the inclusion of Dams is a leaves and seeds at 2.5% of DMI in diets tended to increase all nutrients digestibility and nutritive values expressed as TDN and DCP compared with the control rations. Also, animals fed D3 and D2 diets recorded non significant higher; values of blood serum total protein, albumin and globulin concentration and significant higher (P<0.05) urea levels, (IgG) & (IgM) concentrations and AST activity and had lower (P<0.05) serum ALT activity. Animals fed D3 diet showed significant higher (P<0.05) daily gain, DM, TDN and DCP intake, feed efficiency compared with D2 and D1 diets and consequently the lowest feed cost/kg gain.
In conclusion, replacing 2.5% of dry matter intake (DMI) with Damsisa leaves or seeds for growing lambs diets seems may offer improvement in feed digestibility, feed efficiency and reduce cost of gain.
