Ruminant
Definition:
(a.) Chewing the cud; characterized by chewing again what has been swallowed; of or pertaining to the Ruminantia.
(n.) A ruminant animal; one of the Ruminantia.
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.
(7) Consistent with the convergence hypothesis, only those sites that specify amino acids in the mature lysozyme are shared uniquely with ruminant lysozyme genes.
(8) Each of the primary stress selected isolates was tested in synthetic saliva, rumen fluid simulating the activity in the rumen, rumen fluid followed by pepsin-hydrochloric acid treatment simulating the additional effect of ruminal and abomasal activity, pepsin-hydrochloric acid solution simulating conditions in the abomasum and finally in a trypsin solution as an example of enzyme activity in the gut.
(9) It follows from the results that the effectiveness of some antifasciolics on laboratory animals need not always be in correlation with their effect in ruminants - hence it is necessary to verify the results obtained in laboratory animals and to check them on natural F. hepatica hosts.
