| Abstract | ||||
| Forty crossbred (1/2 Finnish Landrace x 1/2 Rahmani) lambs aging 3-4 months with average body weight of 17 30 kg were divided into five similar groups to invesligate the effect of some medicinal plants (MP) supplementation on daily gain. feed efficiency and reprductive performance. Lambs were fed randomly on one of the experimental diets. The first group received the basal diet, which was free from feed supplementation (FS) and composed of concentrate feed mixture ( CFM) and berseem hay (SH) as control group 01. The tested groups were fed on control diet and with one of the (ollowing FS, Majorme nortens MH (150 mg Ikg live body weight LBW), Nige/fa sativa seeds NS (100 mg/kg L8W), Rosmarinas officina/Is RO (150 mg/kg lBW) or with supplemented medicinal plants mixtures MPM contained third dose of each of the tested MP. for 02.03,04 and 05. respectively. Five digestjon trials were carried out, to evaluate the experimental diets and their effect on digestion coefficients, nutritive values and some rumen parameters. The results showed thai feeding medicinel plants had effect on digestibility coefficients of ruments and nutritive values, goups 04 recorded the highest value in thus respect. Total weight and average daily gain were higher of lambs fed NS or RO with basal diet. The different supplementations did not affect on the rumen pH values. Meanwhile, ammonia N. concentration was Significantly (P<O.05) decreased with (03 and D4 groups) than the control group. The 04 group showed the highest proportion 01 propionic and the lowest of acetic and butyric in comparison with other groups. Lambs in group 4 expressed first ejaculation (puberty) younger by 80,14.5.55.5 and 8.5 days than those in groups 1, 2. 3 and 5. respectively. No significant differences in testosterone concentration (Te) in serum of lambs and scrotal Circumferences in the five groups at all stages of sexual development. | ||||
