..45 ng/mL. Genetic selection has affected growth parameters, although there appears to be no change in fearfulness behavior but an increase in corticosterone levels in stocks from later years...

..Fearfulness scores were only influenced by production phase with the molt having the highest (P < 0.01) score of 3.46. Strain or production phase did not influence the frequency of aggressive and submissive acts...

..However, we have to admit that humanity has reverted to some very deplorable states in history...

..These data indicate that refrigerated transport should be a component in future assessments of egg safety...

..Behaviors during the molt appeared consistent with mechanisms for conservation of body reserves...

..These results suggest that regularly cleaning the cages of older hens may not promote better welfare or improve flock mortality...

..001) at 62 wk of age (172.54 mg/50 g). Although range production did not influence the cholesterol level in the egg, there was an increase in fat levels in eggs produced on the range...

..Use of the technology could allow for egg quality to be maintained for a longer time, which could increase international markets and potentially lead to extended shelf lives...

..0 vs. 0.3%). Egg price was substantially higher for the specialty eggs, averaging $2.18/dozen with a range from 0.88 to $4.38, compared to white eggs, averaging $1.23/dozen and ranging from 0.39 to $2.35...

..3%) birds in the full-fed group had ovarian adenocarcinoma compared with 16 (6.3%) birds in the calorie-restricted group. Calorie restriction in laying hens resulted in a near five-fold reduction in OVAC...

..More important, they showed opportunities to influence cooling rate to improve internal and microbial egg quality...

..Three of the 4 samples were related to the nonfasted treatment, whereas the remaining positive was found in the non-molted treatment...

..Eggs from control strain 5 and the current commercial stock were more easily contaminated than the other strains. These data suggest that genetic selection has altered microbiological defenses of the eggs produced...

..05) than those obtained from the other strains. The results from this study indicate that genetic selection has produced larger eggs containing a lower percentage of yolk while overall egg quality has been maintained or improved...

..It was concluded that pullets and hens could adapt to the physiological stress of beak trimming and out perform, during a lay phase, controls whose beaks were not trimmed...

..Beyond 10 wk of storage, the albumen CO2 content in cryogenically cooled eggs was higher than in the traditionally cooled eggs suggesting chemical changes may have occurred in the albumen...

..CO2-cooling and subsequent storage in CO2 increased Haugh units. The shelf life of shell eggs could be extended to greater than 14 wk when the eggs were CO2-cooled and CO2-stored...

..We concluded that genetic selection has improved production parameters in commercial layers as determined by measurements in this study...

..83 savings/bird between the DFM and control in the 413 cm2/hen treatment). It was concluded that PrimaLac can improve egg size and lower feed costs, regardless of the bird density used in the present study...

..However, CS, T3, T4, and H:L changed with age in relation to the egg production cycle. In addition, the physiological demands of peak egg production and molt (fast) appeared to be similar...

..Storage in a modified atmosphere environment further enhanced these changes. It was found that the CO2 concentration in the air cell of a shell egg can be increased from 0.04 to 48% by CO2 cooling and storage in a CO2 environment...

..Ovomacroglobulin (ovostatin) was found to increase (p < 0.001) over a 6 month period in the late-stage EOC bird providing an initial candidate protein for further investigation...

..Thirty-five percent of the Salmonella isolates were resistant to at least 1 antibiotic. As expected, considerable genetic diversity was observed within and across the different serovars...

..winter. Therefore, these data suggest that season of year and geographic location can affect the temperature of eggs during shell egg processing and should be a component in future assessments of egg safety...

....

..Comparison of crop sections determined a 1.2-4.0 times increase in ratio of lymphoid tissue in day 34 PI SE-challenged hens vs. uninfected control hens...

..We concluded that the use of quicklime as a treatment for broiler litter would initially reduce nitrogen and soluble phosphorus and bacteria counts without negatively affecting bird productivity...

..Thus, the use of alternative nonfeed withdrawal molting methods provide comparable laying hen well-being and may enhance the transition from a productive to a resting state...

..At this point, it is difficult to draw definitive conclusions about how rigid SSOPs should be for the shell egg processing industry...

..These data suggest that traffic patterns for the movement of eggs and materials through the plant should be reevaluated so that cross-contamination is reduced...

..We conclude that Src family kinases are responsible for tyrosine phosphorylation of DAPP-1 in vivo and that PI3K regulation is at the level of PH domain-mediated translocation of DAPP-1 to PI3K products in the membrane...
