    Effect of Previous Plant on Chemical Composition of Sweet Corn Grain
    (MEDWELL ONLINE, 2009) Idikut, L.; Boga, M.; Atalay, A. I.; Kara, S. N.; Kamalak, A.
    The aim of present study was to determine the effect of previous plant on the chemical composition of sweet corn produced as a second crop. The previous plant had a significant effect on the chemical composition of sweet corn grain. The crude protein content of sweet corn grain obtained after Vicia saliva plant was significantly (p<0.001) higher than that obtained after wheat plant. The crude protein content of sweet corn grain ranged from 13.23-14.02% of DM. On the other hand, NDF, EE and NFC contents of sweet corn grain obtained after Vicia saliva plant was significantly (p<0.001) lower than that obtained after wheat plant. However, the previous plant had no significant (p>0.05) effect on the cellulose and ADF contents of sweet corn grain. There is a significant relationship among nutrients contents of sweet corn grains. The CP and ash content were negatively correlated with NDF and ADF, whereas the CP and ash content were positively correlated with EE and NFC contents of sweet corn grain. On the other hand, NDF content was negatively correlated with EE and NFC of sweet corn grain. The EE content was positively correlated with NFC. The previous plant affected the chemical composition of sweet corn grain obtained as a second crop. The sweet corn plant should be sown after Vicia saliva to obtain sweet corn grain with high protein, ash and non-fibre carbohydrate contents.

    Potential Nutritive Value of Honey Locust (Gleditsia triacanthos) Pods from Different Growing Sites for Ruminants
    (TARBIAT MODARES UNIV, 2012) Kamalak, A.; Guven, I.; Kaplan, M.; Boga, M.; Atalay, A. I.; Ozkan, C. O.
    The nutritive values of honey locust pods obtained from different growing sites were evaluated by chemical composition and in vitro gas production techniques. Growing site was found to have a significant (P< 0.001) effect on the chemical composition. The CP contents of honey locust pods ranged from 67.2 to 119.9 g kg(-1) DM. Water soluble carbohydrate (WSC) ranged from 122.3 to 152.2 g kg(-1) DM. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents varied with growing site in the range of 299.6 to 414.3 and 195.3 to 262.9 g kg-1 DM, respectively. Condensed tannin (CT) contents ranged from 27.8 to 148.2 g kg(-1) DM. Polyethylene glycol (PEG) addition significantly (P< 0.001) increased gas production and some estimated parameters of honey locust pods obtained from different growing sites. However, honey locust pods obtained from different growing sites showed variable responses to PEG treatment. There were also significant (P< 0.001) differences among growing sites in terms of gas production and estimated parameters. Organic matter digestibility (OMD) and metabolizable energy (ME) contents of honey locust pods obtained from different growing sites without PEG supplementation ranged from 58.81 to 65.86% and 8.85 to 9.92 MJ kg(-1) DM respectively. The improvement in gas production, the OMD and ME with PEG emphasized the negative effect of tannins on digestibility. The increase (%) in the estimated OMD and ME contents ranged from 6.30 to 15.81% and 5.61 to 14.94%, respectively.
