Eight ruminally cannulated Holstein cows that were part of a larger lactation trial were blocked by days in milk and randomly assigned to replicated 4 x 4 Latin squares to quantify effects of nonprotein N (NPN) content of alfalfa silage (AS) and red clover silage (RCS) on omasal nutrient flows. Diets, fed as total mixed rations, contained 50% dry matter from control AS (CAS), ammonium tetraform...

Unique stomach physiology allows ruminants to utilise any form of dietary nitrogen (N) as a protein source. Ruminant N requirements can be divided into for microbial fermentation and host amino acids. diets often contain non-protein (NPN) compounds, group components that are not proteins but converted by rumen microbes. Therefore, NPN compounds in ruminant serve alternative sources ammoniacal (...

A rough (R) Brucella abortus 45/20 mutant was more sensitive to the bactericidal activity of polymyxin B and lactoferricin B than was its smooth (S) counterpart but considerably more resistant than Salmonella montevideo. The outer membrane (OM) and isolated lipopolysaccharide (LPS) of S. montevideo showed a higher affinity for these cationic peptides than did the corresponding B. abortus OM and...

C ORN silage is a major source of roughage for ruminants in the cornbelt, because it is one of the most productive crops of total digestible nutrients and animal gains per acre. However, to make up a complete growingfinishing ration with corn silage it is necessary to supplement it with sources of energy, nitrogen and minerals. The addition of urea to corn, sorghum or grass at ensiling has give...

A new operation mode for a lateral unified-complementary BiCMOS (hereafter abbreviated as U-CBiCMOS) buffer driver based on a partially depleted CMOS/SOI process is proposed. The scheme utilizes a gated npn or pnp BJT inherent to a nor p-channel MOSFET. Forward current is applied to the base terminal of the channel MOSFET, with a normal pull-up or pull-down MOSFET as a current source, where eac...

this experiment was conducted to assess the effects of daytime cutting management (p.m. vs. a.m. cut), ensiling duration and adding microbial inoculants on chemical composition of alfalfa silage. for this, second growth alfalfa harvested at the early bud stage of development after a sunny day at sundown (about 1900 h; pm alfalfa), whereas the second half was cut next day at sunup (about 0800 h;...

Circuit designers require Computer-Aided Design (CAD) tools when compiling designs into Field Programmable Gate Arrays (FPGAs) in order to achieve high quality results due to the complexity of the compilation tasks involved. Technology mapping is one critical step in the FPGA CAD flow. The final mapping result has significant impact on the subsequent steps of clustering, placement and routing, ...
