Abstract/ Executive Summary:

An experiment was conducted to determine the biomass yield, chemical composition and in-sacco dry matter (DM) degradability of 10 cultivars (WRF-7, TSN-111, TYT-03, TYT-05, TYT-06, TYT-08, TYT-12, ITYN-10, ITYN-14 and ITYN-15) of triticale fodder. The fresh yield of different cultivars of triticale was ranged from 5.03 to 6.85 (t/ha). The organic matter (OM), crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) contents of different cultivars of triticale were found 89.62 to 91.78 %, 21.34 to 25.99 %, 23.09 to 29.99 %, 46.77 to 50.80 %, 0.42 to 0.61 % and 0.33 to 0.41 %, respectively. The yield of DM and CP of different cultivars of triticale were varied from 0.77 to 1.44 (t/ha) and 0.193 to 0.351 (t/ha), respectively. Among different triticale cultivars the highest OM and CP contents were found in TYT-12 (91.78 %) and ITYN-10 (25.99 %), respectively. The highest NDF and ADF contents were found in ITYN-14 (50.80 %) and TYT-05 (29.99 %), respectively among different cultivars. The contents of Ca and P in ITYN-10 (0.61 %) and ITYN-14 (0.41 %), respectively were found to be the highest among the cultivars. Potential DM degradability observed in different cultivars of triticale was higher in ITYN-14 and TYT-05 (84.81 and 81.88 %, respectively) compared to others and relatively poor degradability was found in TSN-111 and TYT-03 (60.74 and 61.35 %, respectively). Therefore, it may be concluded that, the cultivar ITYN-10 will be the promising one due to comparatively higher fresh yield, organic matter (OM), crude protein (CP), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) content and less acid detergent fibre (ADF) fraction cultivated for fodder production in Bangladesh.

Objectives:

To investigate the potential biomass yield, chemical composition, and in-sacco dry matter (DM) degradability of different cultivars of triticale.

Methodology:

The study was conducted with 10 cultivars (WRF-7, TSN-111, TYT-03, TYT-05, TYT-06, TYT-08, TYT-12, ITYN-10, ITYN-14, and ITYN-15) of triticale at Bangladesh Livestock Research Institute (BLRI), Savar, Dhaka from 16 November, 2008 to 18 March, 2009. The study involved in the determination of biomass yield, chemical composition and in- sacco DM degradability of triticale cultivars.Land preparation consists of one deep plaguing followed by 3-4 disking. Weeds and stubbles were removed from the soil and leveled properly. The whole land was divided into 40 plots having 12 m2 each. Fertilizer was applied at the ratio of 140:60:40:20 NPKS/ha. During land preparation, Triple Super Phosphate (TSP,) Murate of Potash (MP) and Gypsum were applied at the rate of 130, 70 and 110 kg/ha, respectively. All the plots received cow dung as basal dose in addition. Triticale seeds were sown on November 16, 2008 in rows by line sowing method with 20 cm row spacing. Weeding and irrigation to all the plots were done two times during experimental period. Harvesting of forage was done at 35 days of growth. Each plot was kept for further growth of vegetation, the green forage was harvested and the 2nd time at 50th day of plantation for obtaining total biomass yield in each plot. Immediate after each harvesting, the fodders were weighed and green forage yield was recorded.During first and second harvesting, the representative samples of triticale fodder were collected at random from each treatment plot. After collection, they were kept in the polythene bags and stored in the freeze for further processing. At the same time, freshly collected 5 representative plants from each plot was chopped into small pieces and kept for determining dry matter content of the forage. Samples were ground in a grinding machine at the size of 1.0 mm and 0.5 mm.

Achievement/Findings:

On the basis of yield of fresh biomass and dry matter in addition to In-sacco DM degradability, it may be concluded that TYT-03 is the best among different varieties of triticale (WRF-7, TSN-111, TYT-03, TYT-05, TYT-06, TYT-08, TYT-12, ITYN-10, ITYN-14, and ITYN-15). Moreover, ITYN-10 is a potential variety of triticale for its higher crude protein yield.
