The objective of the present study was to determine grain feed quality of different broad bean cultivars and lines. For this purpose, Eleven different cultivars and five lines (Emiralem, Histal, Sorgun, Kitik 2003, Sakiz, Eresen 87, Sevil, Reina Mora, Filiz 99, Salkim, Luz De, Otonoto, Seher, EU 4446, Canakkale, Antalya, EU319) were used as the plant material. Experiments were conducted in randomized blocks design with three replications. Effects of genotypes on grain feed quality were found to be highly significant (P≤0.01) Current findings revealed that crude oil content between 0.62 - 1.58%, crude ash content between 1.89 - 3.30%, crude protein content varied between 22.30 - 32.14%, acid detergent fiber (ADF) content between 7.45 - 14.94% and neutral detergent fiber (NDF) content between 16.08 - 28.05%. Seher, EU 4446, Canakkale, Antalya, Filiz 99 and Histal were found to be prominent for hight crude protein and crude oil, thus these genotypes were recommended for animal feeding.

This research was carried out to determine feed quality parameters of leaves and stems of different alfalfa genotypes. A total of 12 alfalfa genotypes was used as the plant material for the study. Alfalfa plants were harvested at the flowering stage. The plants were dried at 70°C and grinded in a hand-mill with 1 mm sieve for chemical analysis. In leaf, the acid detergent fiber (ADF) content of genotypes varied between 21.62 - 27.40%, the neutral detergent fiber (NDF) content between 33.98 - 39.95%, and crude protein content between 24.68 - 28.45%, whereas in stem ADF content of genotypes varied between 50.99 - 57.72%, NDF content between 66.96 - 76.79 %, crude protein content between 8.46 - 11.00%. The RFV ranged from 159.18 to 197.27% and 53.22 to 67.06% for leaf and stem respectively. The leaf to stem ratio of genotypes ranged from 0.72 to 1.60. Considering current results from different genotypes, genotype has a high effect on feed quality. In addition, the rate of leaf to stems is also effective on feed quality. While the protein ratio of the leaves was higher than the stems, the ADF and NDF contents were found to be lower than the stems. So, in the selection of alfalfa genotypes, attention should be paid to the leaf to stem ratio as well as the yield.

The aim of the current experiment was to determine the effect of harvesting stage on the potential nutritive value. Vicia cracca plant was harvested at three maturity stages (before flowering, flowering and seeding). Vicia cracca plants were dried at 70 °C and grinded in a hand-mill with 1 mm sieve for chemical analysis. Crude protein, crude oil, crude ash, condensed tannin, acid detergent fiber (ADF), and neutral detergent fiber (NDF) parameters were investigated as the chemical composition. Harvesting stage had a significant (p ≤ 0.01) effect on chemical composition. Dry matter, NDF and ADF contents were increased with advancing maturity whereas crude protein, crude oil, condensed tannin and crude ash contents were decreased. As a conclusion, the nutritive value of Vicia cracca plant decreased with increasing maturity. Vicia cracca hays harvested at three maturity stages were adequate in term of mineral content for ruminant. Therefore, the Vicia cracca plant can be harvested or grazed before flowering and flowering stages due to high crude protein, crude oil and low ADF and NDF.
