This study was conducted using three multiparous non-lactating rumen-cannulated Holstein-Friesian dairy cows, with the objective of evaluating in situ ruminal degradability and fermentation characteristics novel mixtures winter cereal Italian ryegrass (Lolium multiflorum Lam.) plus silages (mixture A: triticale, oats, barley wheat; mixture B: C: oats; D: ryegrass, wheat). The rumen replacing en...

The objective of this study was to determine the chemical composition, in situ rumen Dry Matter (DMD) and Organic Matter Degradability (OMD48) of Apple tree leaves. In this study, Apple tree leaves were collected from the different parts of East Azerbaijan province. Chemical composition including Dry Matter (DM), Crude Protein (CP), crude Ash (Ash), ether extract, Neutral Detergent Fiber (NDF),...

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...

An experiment was designed to investigate whether the degree of synchrony between the rates of digestion of carbohydrates and N of foods offered as a choice would have an effect, through their consequences, on the short- and long-term diet selection of sheep. Four foods (RL, RH, SL and SH) with the same high metabolizable energy, and similar high metabolizable protein contents were made into pe...
