The efficiency of N utilization in ruminants is typically low (around 25%) and highly variable (10% to 40%) compared with the higher other production animals. has implications for performance environment. Many efforts have been devoted improving ruminants, while major improvements our understanding requirements metabolism achieved, overall remains low. In general, maximal will only occur at expense some losses performance. However, optimal may be achieved through key mechanisms involved...
SUMMARY In the current Dutch protein evaluation system (the DVE/OEB 1991 system), two characteristics are calculated for each feed: true digested in intestine (DVE) and rumen degradable balance (OEB). Of these, DVE represents value of a feed, while OEB is difference between potential microbial synthesis (MPS) on basis available that energy. can be separated into three components: (i) feed crude undegraded but small intestine, (ii) synthesized (iii) endogenous lost digestive processes. Based...
SUMMARY In three experiments, carried out in 1985 and 1986 the Netherlands, effects of herbage maturation rate nitrogen fertilization on rumen degradability organic matter (OM) crude protein (CP) fresh ( Lolium perenne ) were studied using nylon bag technique. Experimental farms at Lelystad Swifterbant (clay soil) Achterberg (sandy provided samples. From results, content digestible CP entering small intestine (DPI) was estimated. Crude sacco OM decreased with increasing grass maturity...
Abstract Herbage (83% Lolium perenne and 17% Trifolium repens ) was harvested 15,28 42 d after second cut, ensiled in 1.5 liter preserving jars either directly, at 20% dry matter (DM), or wilted (30 45% DM). Each variant with without a commercial preparation of cell wall degrading enzymes stored for 90 30°C. Samples were then incubated nylon bags the rumens three cannulated cows 3, 6, 12, 24, 48 288 h to study sacco degradation organic (OM), crude protein (CP), (hemi) cellulose. Addition...
Abstract Enhancing longevity by reducing involuntary culling and consequently increasing productive life lifetime production of dairy cows is not only a strategy to improve farm's profit, but also related improved animal welfare. High rates in are currently attributed fertility problems, mastitis locomotive disorders. Disease incidence high particular the early-lactation period. The disease early lactation has been metabolic stress priority for inability cow adapt effectively new lactation....
