In the present study, chemical composition and in situ rumen dry matter degradability (DMD) of some tree species (cherry, apricot and almond tree leaves) were determined. Crude protein (CP) concentration varied from 6.76% for almond tree to 2.76% for cherry tree, neutral detergent fiber (NDF) and acid detergent fiber (ADF), from 29.2, 20.8% for apricot tree to 20.8 and 15.8% for almond tree lea...

the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...

samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...

We have studied the contribution of ciliate protozoa to the degradation of dietary protein, utilizing 5 defaunated and 6 faunated sheep. Rumen samples from these animals were used as inocular for in vitro determination of the degradability of different protein sources: lupine grain, peanut and soybean cake, and fish meal. We also applied the in sacco method to measure the digestibility of soybe...

this research was conducted to compare effects of electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kgy on soybean meal (sbm) ruminal degradation kinetics of crude protein (cp) and amino acids (aa). the nylon bag and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) techniques were used for this aim. ionizing radiations decreased washout and degradati...

Two experiments were conducted to evaluate the effects of microwaving, autoclaving (moist heating), and roasting (dry heating) on gas production parameters and in situ rumen degradability of soybean meal (SBM). SBM was treated by roasting at 140℃ for 30 and 60 min, and at 160℃ for 30 and 60 min, autoclaving at 121℃ for 20 min, and microwaving for 2, 4, and 6 min. A gas production trial...

Untreated wheat straw (UWS) or ammoniated wheat straw without (AWS) or with (AWSP) a supplement of potato protein of a low rumen degradability was fed to three steers according to a 3 x 3 Latin square design. All rations were supplemented with sugar-beet pulp and minerals. Voluntary organic matter intake (OMI, g/kg0.75 per d) was 67.8, 76.0 and 80.1 for whole rations (51.1, 59.7 and 59.2 for st...

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...

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...
