Abstract

Grasses, forbs and shrubs are the most important LIFE FORMS which have considerable role in livestock feeding in ARID AND SEMI-arid environment. Shrub plants have important role in the feeding of livestock and stability of range ecosystems because there are short favorite growth condition for other forms of range plants and fragile environment in these ecosystems. Sampling was carried out in three growth stages (vegetative, flowering and seed shatter) with three replications. Five individual plants of each species were collected in each replication and crude protein, acid detergent fiber, dry matter digestibility, metabolizable energy, phosphorus and calcium contents were measured in each mixed sample. One-way ANOVA and Duncan’s test were used to analyze the data. The results showed that different LIFE FORMS have different NUTRITIVE VALUEs and varies during phenological stages. Amount of crude protein in forbs (13.2%) was higher than those of shrubs (11.2%) and grasses (9.9%) and indicated significant differences Result of acid detergent fiber indicated grasses had significantly higher acid detergent fiber (42.2%) than those of forbs (36.5%) and shrubs (24.1%). Dry matter digestibility in shrubs (68.3%) was higher than those of forbs (58.3%) and grasses (52.6%). Result also indicated that percent of crude protein decreased in the forbs from 20.1 to 3.1 and in grasses from 14.4 to 5.1 and in shrubs from 12.1 to 9.5 in vegetative to maturity stages respectively.
