nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...

Three cannulated Tswana steers were used to investigate the rumen degradability of mopane worm (Imbrasia belina) by measuring the amount of dry matter (DM) and crude protein (CP) disappearing at incubation periods up to 72 h. The effective degradability (ED) of DM and CP in the rumen was calculated at outflow rates of 0.03 / h (ED0.03) and 0.05 / h(ED0.05). Rumen degradable CP (RDP) was estimat...

The protection of sunflower meal (SFM) proteins by treatments with solutions of malic acid (1 M) or orthophosphoric acid (0.67 M) and heat was studied in a 3 × 3 Latin-square design using three diets and three rumen and duodenum cannulated wethers. Acid solutions were applied to SFM at a rate of 400 ml/kg under continuous mixing. Subsequently, treated meals were dried in an oven at 150°C for 6 ...

Synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants The concept of synchronization energy and protein was first by Jhonson, Implying that maximum microbial protein synthesis could be achieved by matching the rate of Organic Matter and protein degradation. Synchronization of rumen available...

This study investigated the effects of feeding finely ground starter diets containing either 18 or 22% crude protein (CP) content [dry matter (DM) basis] and high low ratios rumen-undegradable to rumen-degradable (RUP:RDP) on growth performance, nutrient digestibility, ruminal fermentation, blood metabolites, urinary purine derivatives in dairy calves. A total 48 three-day-old female Holstein c...

We hypothesized that microbial efficiency and output from fermentation in the rumen would be optimized when peptide supply was balanced with peptide requirement of ruminal microflora. This study was conducted to measure response of varying rumen degradable peptide (RDPep) supply on ruminal fermentation characteristics and steer growth. A continuous culture experiment was conducted with diets fo...
