Pregnant Barki sheep and Shami goats were used to evaluate the effects of feeding cultivated salt-tolerant forages Additionally, results proved the economic value of using such products, as they reduced the cost of milk production.Ībstract: The study was carried out at South Sinai Research Station, South Sinai Governorate, Egypt.at 250 g/kg of dietary DM, as a source of fibre, did not negatively impact the lactation performance of sheep. were fed to Awassi ewes at a level of 250 g/kg of dietary DM. Additionally, results proved the economic value of using such products, as they reduced the cost of milk production. Results showed that the inclusion of OC and ATR did not negatively impact lactation performance. The digestibility of EE was greater in the OC group than in CON and ATR groups. Dry matter digestibility was greater in ATR compared to CON and OC groups. In study 2, 18 ewe lambs were assigned the same diets used in study 1 to evaluate the effects of OC and ATR on nutrient digestibility and N balance. Milk production cost was lower in the OC and ATR compared to the CON group. Content of milk total solids and fat were greater in ATR diet than CON and OC diets. 0001) in OC diet compared to CON and ATR diets. Ether extract (EE) intake was greater (p <. Ewes fed CON diet had greater DM, neutral detergent fibre, and acid detergent fibre intakes than OC and ATR groups. Ewes and lambs were housed in individual pens. In study 1, 33 newly lambed ewes and their lambs were randomly assigned one of three diets: The control diet (CON), 250 g/kg of OC, or 250 g/kg of ATR dry matter (DM). (ATR) or olive cake (OC), as a foraging source substitute for wheat straw. The objective of the two studies was to evaluate t effects of feeding on lactating Awassi ewes (study 1) and lambs (study 2), fed on a diet of Atriplex halimus L.

The F/DcmEA showed an interesting and significant antioxidant activity in all tests as the other F/DieEA, F/n-BUOH, F/aqueous represented the activity of trapping the free radical DPPH of C50 = (3.073 ± 0.088mg/ml), a reducing power of iron (433.55 ± 24.36mgQE/gE), and a total antioxidant capacity of the Mo (VI) reduction test of (20.28 ± 1.96mgEAG/gE), and the determination of IC50 of β-carotene bleaching (0.92 ± 0.0175mg/ml). Therefore, flavonoid levels F/DieEA and F/DcmEA were almost identical (9.515 ± 0.277 mgQE/gE), (9.238 ± 0.119 mgQE/gE). High levels of total polyphenols and condensed tannins were found in F/DieEA (23,437 ± 0.251mgGEA/gE), and F/DcmEA (17,251 ± 0.354mgCE/gE), respectively. This study aimed to determine TPP (total polyphenols), FLV (flavonoids) and CT (condensed tannins) on one hand and on the other hand, to evaluate the antiradical activity of the hydroalcoholic and aqueous fractions by four different methods including: DPPH test (2,2-diphenyl-1-picrylhydrazil), FRAP test (antioxidant activity by the iron reduction method), BCB test (β-carotene bleaching), and TAC test (antioxidant capacity) total) by the phosphomolybdate method. In the present study, four fractions were prepared from leaves extract of Atriplex nummularia. These secondary metabolites may explain the low palatability of Atriplex halimus compared to A. Atriplex halimus synthesized more oxalate, tannic phenols, condensed and hydrolyzable tannins than A. halimus seedlings (1.57% and 1.47%, respectively). nummularia contained significantly higher levels of condensed tannins compared to A. Young plants of the 2 species had higher levels of condensed tannins compared to older plants. Clipping had no effect on the levels of tannic phenols, condensed and hydrolyzable tannins. halimus contained more condensed and hydrolyzable tannins (1.05% and 0.67%, P < 0.0001) than A. halimus contained more oxalate than the young seedlings. mularia contained more oxalate than old plants whereas old shrubs of A. Clipping had no effect on oxalate concentration. halimus accumulated more oxalate in spring than those of A. Oxalate levels averaged 8.29 and 4.92% in spring and fall season, respectively.
Atriplex halimus contained higher levels of oxalate (7.00%) compared with A. During spring and fall seasons, 20 shrubs of each species were selected randomly at each location, 20 similar twigs per shrub were clipped and analyzed for oxalate and tannins.
plants commonly used for revegetation of degraded rangelands. The study was conducted at 3 locations in the arid region of Jordan to assess the seasonal changes of oxalate and tannins in Atriplex halimus L.
