To determine the nutritional value of five halophytes, Aeluropus lagopoides, Atriplex leucoclada, Desmostachya bipinnata, Halopyrum mucronatum, and Halocnemum strobilaceum, this study was conducted in 2016 in Hormozgan province. Plant samples were collected in three phenological stages including vegetative growth, flowering and seeding, and eight forage quality traits (CP, DMD, WSC, ADF, CF, NDF, ME and ash percentage were measured. Data analysis of variance was performed as a factorial experiment in a completely randomized design and the means were compared with Duncan's multiple rsnge test in SPSS software. The results showed that the effect of species for all traits, the effect of phenological growth stages for four traits: (CP), (DMD), (ash), and (ME), and the interaction effect of species and phenological growth stage were significant for all quality indicators except (WSC). The highest forage quality was obtained at vegetative growth stage and Atriplex leucoclada was superior to other halophytes in terms of nutritional value. Therefore, the use of this native species instead of non-native ones of this genus is recommended in rangeland improvement of areas with similar rainfall.

Awareness of the nutritional value of different rangeland plants can help animal husbandries to prepare a suitable diet; hence some experiments were conducted to determine the chemical compositions, minerals, gas production and other fermentation parameters of four range plants that can be grown in Torbat-e Jam (including Arctium lappa, Verbascum thapsus, Althaea officinalis and Ferula hermonis), Iran. The above plants were randomly collected before flowering. The range of crude protein (15.85- 22.87%), ash (8.27-16.10%), crude fat (0.85-5.75%), neutral detergent fiber (19.27-37.53%), acid detergent fiber (15.53-26.53%), acid detergent lignin (3.83-5.43%), and crude fiber (12.49-21.74%) was different among four plant species. The highest amount of calcium (12.26 g/kg DM) was related to Althaea officinalis. The parameters of gas production and other fermentation parameters were also different among the plants, so that the maximum amount of gas production after 12, 24, and 48 h incubation (47.32, 61.64, 71.21 ml, respectively), potential gas production (75.70 ml), dry matter and organic matter digestibility (82.99 and 84.60 %, respectively), metabolizable energy (10.66 MJ/kg DM), net energy for lactation (6.51 MJ/kg DM), and total volatile fatty acids (36.62 mmol/L) were found in Verbascum olympicum. There was a negative correlation coefficient between the gas produced after 24 h incubation with ether extract, crude protein, and ammonia nitrogen. Comparison of the gas production, fermentation and degradability parameters among studied plants indicated that Verbascum thapsus had higher potential nutritive value.

Determination of rangeland forage quality is an important factor in assessing the nutrition status of livestock dependent on rangeland, determining suitable grazing time, increasing livestock efficacy and less damaging to rangelands. This study was conducted to determine the nutritional value and digestibility of four dominant species of Compositae family in Baft rangelands located in Kerman province. The species including: Artemisia aucheri, Artemisia persica, Scorzonera tortusissimaand Cousina sicigera, which weresampled in phonological stages of vegetative growth, flowering and seeding. The results showed that the mean values of chemical composition of the mentioned species at different growth stages were 9.94, 8.9, 6.21 and 10.40% of crude protein (CP), 45.62, 45.77, 61.07 and 42.83% of NDF and 32.77, 33.05, 46.61 and 31.73% of ADF, respectively. By increasing age of all plant species, CP was decreased (P<0.01) but except for Scorzonera tortusissima, the values of NDF and ADF were increased in other species (P<0.01). The average digestibility of the mentioned species dry matter at vegetative, flowering and seeding stages were 57.41, 53.54, 45.34 and 39.67%, respectively. The average of metabolizable energy (ME) of the mentioned species at vegetative, flowering and seeding stages were estimated to be 2.24, 2.24, 1.86 and 2.26 Cal/g, respectively. The average concentrations of mineral elements such as calcium, sodium, potassium, magnesium, iron and manganese of these four rangeland species were more than the critical requirements of sheep and goat, while the concentrations of phosphorus, copper and zinc in these plants were less than the critical level for sheep and goat requirements. Generally, the four species studied in terms of CP and ME, especially in the early stages of growth, provide the needs of sheep and goats in the region.
