Rumination


Definition:

  • (n.) The act or process of ruminating, or chewing the cud; the habit of chewing the cud.
  • (n.) The state of being disposed to ruminate or ponder; deliberate meditation or reflection.
  • (n.) The regurgitation of food from the stomach after it has been swallowed, -- occasionally observed as a morbid phenomenon in man.

Example Sentences:

  • (1) The data suggest that major differences may exist between ruminants and non-ruminants in the response of liver metabolism both to lactation per se and to the effects of growth hormone and insulin.
  • (2) In the clinical trials in which there was complete substitution of fat-modified ruminant foods for conventional ruminant products the fall in serum cholesterol was approximately 10%.
  • (3) The different hydrolytic, fermentative and methanogenic activities of these populations ensure the efficient degradation of cell wall constituent in forages (cellulose, hemicellulose, pectin) ingested by ruminants.
  • (4) Ruminal digestion (% of intake) of neutral detergent fiber (NDF) and hemicellulose decreased linearly (P less than .05), whereas acid detergent fiber (ADF) digestion responded in a cubic (P less than .05) fashion to increasing concentrate level; NaHCO3 improved ruminal digestion of NDF (P less than .10) and ADF (P less than .05), but not hemicellulose.
  • (5) The results of these trials suggest that increasing level of dietary NaHCO3 greatly increases the proportion of time ruminal pH is above critical levels for ruminal protein and dry matter digestion, but does not affect total tract nutrient digestion when 50% concentrate diets are fed.
  • (6) Extents of in situ ruminal digestion (72 h residue) for NDF, hemicellulose and cellulose were lower (P less than .05) for full-head than for late-boot-stage bromegrass.
