The evaluation of foodstuffs provides the animal nutritionists with necessary information to adjust the diet from a physiological and economic point of view, so that the animal performance be desirable. Nowadays, there are various methods for evaluating ruminant feed intake. One of the most important methods is in situ nylon bag technique. Prosopis farcta is one of plants which is used as forag...

An in situ study was conducted on four rumen-cannulated wethers to determine (using (15)N infusion techniques) the microbial contamination (mg bacterial DM or crude protein (CP)/100 mg DM or CP) and the associated error on the effective degradability of fourteen feeds: barley and maize grains, soyabean and sunflower meals, full-fat soyabean, maize gluten feed, soyabean hulls, brewers dried grai...

background to current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (ivep). objectives the aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on ivep yield. materials and methods ovaries from slaughtered ewes in breeding sea...

The objective of the study was to quantify annual and seasonal differences in the chemical composition, in vitro gas production, in situ degradability and ruminal fermentation of grazing steers' diets. Diet samples were collected with four esophageal cannulated steers (350±3 kg BW); and four ruminally cannulated heifers (342±1.5 kg BW) were used to study the dry matter degradation and fermentat...

This study aimed to evaluate the effects of cellulase and xylanase plus enzymes on in vitro ruminal fermentation of Eragrostis curvura hay, maize stover and a total mixed ration (TMR) at six levels of application. The feed samples were incubated for 2, 12, 24, 32, 48, 72, h in an in vitro batch culture with buffer and ruminal fluid, and the fibrolytic enzymes associated with the six levels of a...

Magnesium (Mg)-based stents are extensively explored to alleviate atherosclerosis due to their biodegradability and relative hemocompatibility. To ensure the quality, safety and cost-efficacy of bioresorbable scaffolds and full utilization of the material tunability afforded by alloying, it is critical to access degradability and thrombosis potential of Mg-based alloys using improved in vitro m...
