[The effect of Rumensin on the metabolic profile of rumen fluid in feedlot cattle]. 1980

R Dvorák, and J Dvorák, and Z Vrba, and M Hradilová, and J Ondrová

The effects were studied of sodium monensinate dosed 125 mg on the metabolic profile of rumen fluid. The experiment was conducted under current farming conditions in a pavilion cattle fattening house. The experiment, which lasted 367 days, comprised 985 bulls of the Bohemian Spotted breed. The feed ration was based on silage with an additive of dried poultry litter and concentrates. The additive was administered in concentrate mixture, 125 mg per head/day. After the start of the experiment want of appetite to sodium monensinate was observed. The animals took approximately four weeks to adapt completely to the additive. The following characteristics were investigated to study the metabolic profile of rumen fluid: actual acidity, total titration acidity, ammonia, total nitrogen, lactic acid, total volatile fatty acids, per cent acetic acid, per cent propionic acid, molar ratio acetic acid: propionic acid, per cent iso- and n-butyric acid, absolute number of infusoria and energy net yield of volatile fatty acids. Increased levels of the clinico-biochemical parameters of the metabolic profile of rumen fluid were found in lactic acid, propionic acid and energy net yield of volatile fatty acids. The per cent of propionic acid increased at some samplings by up to 116%. A drop was recorded in total nitrogen, per cent acetic acid, per cent butyric acid, molar ratio C2 : C3 and total number of infusoria. The decrease in the per cent of acetic acid ranged around 16% and the drop in butyric acid level amounted at some samplings up to 78%. No response to the additive was observed in the other characteristics of the metabolic profile of rumen fluid.

UI	MeSH Term	Description	Entries
D008985	Monensin	An antiprotozoal agent produced by Streptomyces cinnamonensis. It exerts its effect during the development of first-generation trophozoites into first-generation schizonts within the intestinal epithelial cells. It does not interfere with hosts' development of acquired immunity to the majority of coccidial species. Monensin is a sodium and proton selective ionophore and is widely used as such in biochemical studies.

D000143	Acids	Chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. (Grant & Hackh's Chemical Dictionary, 5th ed)	Acid
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012417	Rumen	The first stomach of ruminants. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. The rumen is lined by mucous membrane containing no digestive glands, but mucus-secreting glands are present in large numbers. Coarse, partially chewed food is stored and churned in the rumen until the animal finds circumstances convenient for rumination. When this occurs, little balls of food are regurgitated through the esophagus into the mouth, and are subjected to a second more thorough mastication, swallowed, and passed on into other parts of the compound stomach.
