Bermudagrass [Cynodon dactylon (L.) Pers.] is productive in summer but is dormant for much of the year. The grazing season for bermudagrass pastures can be lengthened by fall interseeding of rye (Secale cereale L.). In trial 1, performance of Stocker cattle (222 kg average BW) grazing monocultured rye (MR) followed by bermudagrass (MB) in separate pastures was compared with that of cattle grazing interseeded rye-bermudagrass pastures (IRB). Spring forage production and 1989 carrying capacity were greater (P .10)between systems. Summer bermudagrass gain and grazing days from the two systems varied by year. Overall gain per hectare of land grazed and animal grazing days per hectare were greater (P 2.0, indicating a greater efficiency for interseeding. In trial 2, ruminally fistulated heifers (395 kg average BW) were used to estimate forage intake and nutritional components from the two types of rye pastures. Dietary forage from MR was higher (P ≤ .01) in neutraldetergent fiber, ADF, and in vitro organic matter digestion (IVOMD, 48 h) and lower (P .10) between MR and IRB dietary forage. Heifers grazing MR had higher (P |
