Estimation of ruminal degradability of four genotypes of sorghum (Sorghum bicolor (L.) Moench) using in situ technique - DOI: 10.4025/actascianimsci.v27i4.1150
This experiment was carried out to evaluate “in situ” degradability of dry matter, neutral detergent fiber (NDF) and acid detergent fiber (ADF) of four sorghum genotypes (ATF53*9929036; ATF54*9929036; 217*9929012 and VOLUMAX). Four Holstein cows with ruminal fistula were fed on sorghum silage “ad li...

| Sumario: | This experiment was carried out to evaluate “in situ” degradability of dry matter, neutral detergent fiber (NDF) and acid detergent fiber (ADF) of four sorghum genotypes (ATF53*9929036; ATF54*9929036; 217*9929012 and VOLUMAX). Four Holstein cows with ruminal fistula were fed on sorghum silage “ad libitum”, and 2.0 kg of concentrate. The animals were alloted in a randomized block design, with four replicates, in a split plot arrangement. The genotypes were considered the parcels and the incubation time the sub-parcels. The higher effective dry matter degradability were found in VOLUMAX genotype, (56.22; 53.35 and 50.90%) for all passage rates, (2; 5 and 8%/h, respectively). The genotypes ATF53*992903 and ATF54*9929036 showed higher NDF effective degradability, 32.17 and 33.47% respectively, and ADF effective degradability, 34.81 and 35.50%, at 2%/h passage rate |
