Influence of some medicinal plants as feed additives on digestibility, nutritive value, fermentation in the rumen and reproductive performance of male lambes
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 investigate the effect of some medicinal plants (MP) supplementation on daily gain, feed efficiency and reproductive 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 D1. The tested groups were fed on control diet and with one of the following FS, Majorme hortens MH (150 mg /kg live body weight LBW), Nigella sativa seeds NS (100 mg /kg LBW), Rosmarinas officinal RO (150 mg/kg LBW) or with supplemented medicinal plants mixtures MPM contained third dose of each of the tested MP, for D2, D3, D4 and D5, respectively. Five digestion trials were carried out, to evaluate the experimental diets and their effect on digestion coefficients, nutritive values and some rumen parameters.
The results showed that feeding medicine I plants had effect on digestibility coefficients of rumens and nutritive values, groups D4 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<0.05) decreased with (D3 and D4 groups) than the control group. The D4 group showed the highest proportion of prop ionic 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 (TC) in serum of lambs and scrotal circumferences in the five groups at all stages of sexual development, Keywords: Medicinal plants, lambs, digestibility, daily gain, testosterone concentration, reproductive performance, sheep.
