Determination of Some Shrub Seasonal (Spring, Summer and Fall) Leaf Yields, Nutrient Content and Digestibility

The purpose of this study was to determine spring, summer and fall yield of 24 shrubs, gathered from different province of west transtitional region. In spring, the highest fresh leaf yields on in spring Rhus coriaria L, Paliurus spina-cristi Mill, Rosa pulverulenta M, Bieb, on in summer Rhus coriaria L, Clematis viticella L, Salvia wiedemannii Boiss. and on in fall Salvia wiedemannii Boiss, Elaeagnus angustifolia L, Clematis viticella L. were found. Rhus coriaria L. give the highest leaf/steam ration. While the lowest value was taken from Globularia trichosantha Fisch. In nutritient content and rumen digestibility 48 hours. Dry matter was over of 90 % in all shrubs. It was determined that variation in shrubs were 2.94-22.06% ？n crude protein, 3.02-19.52% in ash, 72.54-93.54% in organic matter, 1.20-13.50% in oil content, 20.81-55.54% ADF, 22.28-71.11 NDF, 5.88-41.50 ADL, cellulosic content 5.90-44.12, hemicellulosic content 0.27-33.91 and 28.89-98.33% 48 hours rumen digestibility. According to the obtained values, results showed that, they were determined that bush plants are able to grazing especially in dry seasons and can contribute as additional feed
