Potential Nutritive Value and Ensilage Characteristics of Forage Sorghum Varieties

3.137 730



In this study, ensile characteristics and nutritive value of different sorghum varieties were investigated. Sorghum genotypes were grown in Kahramanmaraş Province of Turkey, and harvested at dough stage for silage. Experiments were carried out in randomized block design with 3 replications. Five Sorghum genotypes (ICSB 502, ROX, SC 941 ICSB 564 and B24) were used as plant materials of the study and crude protein (CP), dry matter (DM), crude ash (CA), acid detergent fiber (ADF), neutral detergent fiber (NDF), fleig score, pH and some fatty acid contents were determined.

Significant differences were observed among varieties with regard to investigated parameters. The variations in chemical compositions were affected by genetic difference between genotypes.  The CP values of genotypes varies between 6.76 to 10.70%, NDF  between 47.82,and 61.06 ADF between 30.51 and 44.04%,.The lactic acid and butyric acid contents ranged  from 19.00 to 44.38 and 2.14 to 4.48 g/kg DM, respectively. The fleig score ranged from 90.21 to 97.11. Results of present study revealed that sorghum could be ensiled at dough stage to obtain high quality silage and SC 941 could be recommended as a good source of feed for the local producers of the region.
