J. Anim. Sci. Vol. 88, E-Suppl. 2/J. Dairy Sci. Vol. 93, E-Suppl. 1/Poult. Sci. Vol. 89, E-Suppl. 1 ultrasonography was used to determine ovarian hemodynamics. Ewes fed 360 ARG had greater serum arginine concentration than CON, 90 ARG, and 180 ARG on d 11 (175.5 vs. 153.2, 132.3, and 145.4 ± 8.6 nmol/mL, respectively; P = 0.01) and d 12 (166.4 vs. 142.7, 121.7, and 128.2 ± 7.4 nmol/mL, respectively; P = 0.002). On d 11, arginine as a percent of total amino acid concentration was increased in 360 ARG compared with CON and 90 ARG (7.16 vs. 6.19, 5.70 ± 0.34 nmol/mL, respectively; P = 0.04). Total essential amino acid concentration was elevated in 360 ARG compared with 90 ARG and 180 ARG (P = 0.08) on d 12. Arginine supplementation increased peak systolic velocity in the corpus luteum for 360 ARG and 90 ARG compared with CON (30.53 and 32.59 vs. 22.63 ± 2.48 cm/s, respectively; P < 0.07). Flow time (milliseconds) in the ovarian hilus and corpus luteum was increased in 360 ARG compared with all other treatments (P ≤ 0.02 and P ≤ 0.06, respectively). Supplemental rumen-protected arginine had no effect on serum concentration of progesterone (P > 0.50). Results indicate that rumen-protected arginine supplemented to ewes at the rate of 360 mg/kg BW may increase circulating serum arginine concentration, in addition to increasing ovarian blood flow.

0.05) in odor between treatments and the control BSP pieces for all storage days. Lactic acid treated BSP pieces were more likely to be lighter, greener, and more yellow throughout the storage period when compared to control BSP pieces. Lower microbial counts and indistinguishable odor differences were achieved with 2.00% LA treated BSP pieces. Using 2.00% LA in beef trimmings may provide a mic...

متن کاملManaging Criticality of ASAS Applications
What must happen to assure that some aspects of separation services can safely be performed in the cockpit? The ASAS concept proposes the transfer of responsibility for maintaining aircraft separation from the ground to the airborne side under specific conditions. With the emergence of an operational requirement for ASAS applications, their safety issues need to be addressed as soon as possible...
