Tocopherol more bioavailable than tocopheryl-acetate as a source of vitamin E for broilers

Poultry
Vitamin E is typically supplied in the form of tocopheryl-acetate (T-Ac) since tocopherol (T) has stability issues. Tocopheryl-acetate, however, must be hydrolyzed in the intestines before it can be absorbed, a step that is purportedly rate-limiting for its bioavailability. The objective of this study was to compare the efficiency of absorption of T-Ac and T in broilers. In addition, two test procedures were evaluated in which animals received the test substances for either 2 or 4 days only. Animals were adapted to diets without supplemental vitamin E (feedstuffs contributed 14±1 ppm natural vitamin E (RRR-tocopherol)) till the age of 25 d (individual housing) or 28 d (group housing). Subsequently, they were fed T-Ac at 80, 53, 36, 24, o

Review: Unlocking the limitations of urea supply in ruminant diets by considering the natural mechanism of endogenous urea secretion

Ruminants
Ruminants have evolved with the capability to recycle endogenous urea to the gastrointestinal tract (GIT). Ruminal ammonia derived from urea recycling makes a net contribution to digestible N flow if it is used to synthesise microbial protein. The dynamics of urea recycling and its quantitative importance to the N economy of ruminants are affected by dietary and physiological factors. In general, the transfer of endogenous urea to the GIT is related positively to blood urea concentration and rumen-fermentable energy supply and negatively to ruminal ammonia concentration. After consumption of a meal rich in rumen-degradable N, ruminal ammonia concentrations peak and can exceed the rate of carbohydrate fermentation, resulting in inefficient ammonia capture by microbes. These periods are characterised by greater ruminal ammonia efflux and reduced urea influx. A low ruminal ammonia concentration over time can stimulate recycling of endogenous urea-N to the rumen and its capture into microbial protein and reduce N excretion.
