Summary of Methods: Fistulated steers were fed jointed goatgrass (Aegilops cylindrica Host.) seed at three rates (0.64 1.28 and 2.56 lbs/steer) in a short term pen study to determine the viability, germination and emergence of the seed after cattle digestion. Samples were taken from the rumen and the feces of the cattle 24, 36 and 48 hours after feeding.
Article Summary / Main Points: Viability rate of seeds recovered from the rumen was 75% and feces was 76%. Germination rates for seeds recovered from the rumen and feces were 26 and 28%, respectively. There was 56% emergence of the weed seed collected from the cattle.
