“…Overall germination percentage of the intact untreated seeds (26.00%) was significantly higher (Tukey test, p < 0.05) than that of seeds recovered from faeces (4.27%). This is in agreement with previous studies on herbaceous seeds dispersal via endozoochory (Shayo & Uden, 1998;Razanamandranto et al, 2004;Viero et al, 2018). The germination percentage was greatest for seeds from mechanical scarification with sandpaper (96%), intermediate for seeds from hot water scarification (52.80%), and least for seeds from passage through cattle tracts (4.27%) (Tukey test, p < 0.05).…”

“…It should be noted that the highest recovery rate was obtained 2 days after ingestion. Viero et al (2018) assessed the recovery of weedy rice (Oryza sativa L.) and barnyardgrass (Echinochloa crusgalli L.) seeds and found that they passed through the gut of the cattle on the first day after ingestion, with zero recovery. However, maximum recovery was obtained 2 days after ingestion, exhibiting sigmoid behaviour and declining to zero (Viero et al, 2018), similar to the results of the present study.…”

“…In weedy rice and barnyardgrass, germination declined in seeds that had passed through the gut of cattle (Viero et al ., 2018). This phenomenon may be directly related to the loss of seed viability as a function of retention time in the rumen (Lisboa et al ., 2009).…”
