Leaves and Twigs for six species of trees and shrubs consumed by livestock and wild ungulates: Albizia lebbek, Robinia pseudoacacia , Acasia farnesiana , Leucaena leucocephala , Populus negra , Morus alba were evaluated for comparative seasonal contents of crud protein, ash, ether extraction, crud fiber, carbohydrates, organic matter, dry matter, N, P, K and Ca .Samples were collected in five dates (15th April, 15th Joun, 15th Auogest, 15th October, 15th December<br /> in 2001) in Ninevah Governorate.The result indicated that there were significantly differences among sampling dates, species and plant parts. Content of ash, ether extraction, crud fiber, calcium and dry matter was increased as the season progressed whereas crud protein, soluble carbohydrates, organic matter, potassium, phosphorus and nitrogen content decreased. The results exhibited that the first sampling date (15th.April) was the best date to collect and dried this forage which gave higher percentage of crude protein, soluble carbohydrate, organic matter, phosphorus, potassium and less percentage of crude fiber than other dates to use it as a supplementary nutrition for Livestock and wild ungulates. Also higher nutritive compounds and element were found in leaves than twigs. The legume trees and shrubs have higher percent of crud protein than others.
