Assesment of Biochemical Forage Quality of Sweet Sorghum [Sorghum bicolor (L.) Moench ssp. saccharatum]

In this study, it was aimed to determine some forage quality characteristics of sweet sorghum genotypes in semi-arid climatic conditions. The experiment set up randomized complete block design with 4 replicates. Research carried out 2016 and 2017 under Harran Plain second crop conditions, Sanliurfa, Turkey. the study 21 were used. Crude protein content, crude ash, acid detergent fiber (ADF), neutral (NDF), dry matter digestibility, consumption, determined study. Significant differences found between for tested (P≤0.01). According average two years, content ranged from 4.20% (Tracy) 5.90% (USDA S.Africa), ash 4.44% (Theis) 6.90% (Topper 76), (ADF) 27.84% (Nebraska sugar) 36.30% (USDA-Zaire). highest NDF value obtained USDA-Zaire genotype (56.49%) whereas lowest values seen at N98 (43.11%). Dry digestibility 60.62% (USDA-Zaire) 67.21% sugar), consumption 2.14% 2.85%. relative feed (148.95) (101.00). Net energy 1.38 Mcal kg-1 1.50 sugar). Considering properties examined terms quality, that net low. But ADF, NDF, digestible matter, within acceptable levels. Nebraska sugar, Topper 76, N98, Roma, M81E, Tracy Corina as best sorghum. It can be used a source.
