A single injection of 15 g NaCl into the rumen, which increased the osmotic pressure of rumen fluid from 369 to 474 mOsmol/kg, resulted in a decrease in the transfer of blood urea into rumen fluid from 2.3 to 1.6 g N/day in sheep fed 50 g of chaffed oaten hay every hour. It is concluded that the reduced urea transfer was the result of a reduced urea input via saliva. The rumen wall remained vir...
It has been suggested that the rumen microbiome and rumen function might be disrupted if methane production in the rumen is decreased. Furthermore concerns have been voiced that geography and management might influence the underlying microbial population and hence the response of the rumen to mitigation strategies. Here we report the effect of the dietary additives: linseed oil and nitrate on m...
abstract the aim of this study was to evaluate the effect of ajowan essential oils (aeo) on rumen fermentation using in vitro gas production. therefore, different doses of aeo (i.e., 0, 150, 300, 450 or 600 ppm) were added to the syringes of the gas production. a typical diet of growing lambs was used as fermentation substrate. at the first step, the gas production syringes were in...
An artificial rumen for the study of nutrient digestion by the micro-organisms of the rumen was initially developed by Louw, Williams & Maynard (1949). In this, the micro-organisms were contained in a semi-permeable dialysis sac and the diffusible products of digestion removed by a salt solution, the composition of which approximated to that of saliva and which flowed continuously past the outs...
