Hatching percentage

Most poultry production, and a growing percentage of swiae production, takes place ia iatensive, confinement operations. Much of the poultry production is carried out under a system of vertical iategration ia which a producer hatches the chicks, grows them ia the producer s faciUties or ia contract facihties, provides the feed, processes the animals, and markets the product. This system of vertically iategrated production is not as common ia the swiae iadustry. 

This chart was devised in the nineteenth century and consists of a white card with black cross-hatching. The percentage of hatching increases by divisions of 20 per cent each Ringleman number. Therefore 0 = white, I = 20 per cent, 2 = 40 per cent, 3 = 60 per cent, 4 = 80 per cent 5 = black.

Figure 10 Corpulence of cod caught on various grounds in the spring of 1966, as shown in the maximum diameter of the caudal peduncle expressed as a percentage of the body length. (After Love et al., 1974.) In this figure, and figures 11 and 12 the Faroe Bank stock is demarcated by cross-hatching.

Application of the Hatch equations to a screen analysis is as follows A summation curve is plotted on log-probability grid. The percentage less than calibrated sieve-size is plotted instead of the usual percentage less than stated sieve-size. If the summation curve is a straight line, Eq (5-9) applies. The method is useful where precise information is desired on particle-size of a screened product. 

Manzamine A, neo-kauluamine, and chloroquine were evaluated against both medaka fry and eggs and were found to be more toxic than ethanol alone in both cases (in control groups, percentage fry survival and eggs hatching were over 94 % and 90 %, respectively). Medaka fry were 2.3- and 3.0-times more sensitive than were eggs... 

Fig. 6. A, ChE activity of homogenates from the cerebrum (white columns) and retina (hatched columns) of atropinized male rats 16 h after subcutaneous administration of 2-MPAM-ES iodide (0.325 mg/kg). Two hours prior to the administration of the inhibitor the animals were pretreated with subcutaneous injections of 2,4-dinitrophenol (10 mg/kg), ouabain (1 mg/kg), and X-ray irradiation, 5,000 rads, through the head. Enzyme activities are expressed as percentages of the normal. Erythrocyte ChE activity (not shown on the figure) was reduced to 24% (see also Fig. 3). B, Columns denoting ChE in the cerebrum and retina as in A, but from animals pretreated with paraoxon (0.3 mg/kg) intravenously. The left pair of columns represents control animals which were given no subsequent reactivator therapy, whereas the following 3 pairs of columns show the effect of the enzyme reactivators indicated on figure. The ChE reactivation is seen to be more pronounced in the retina than in the cerebrum. Reactivation of erythrocyte ChE (not shown) was materially complete in these experiments. For further details (reactivator dosage, number and time-spacing of doses, etc.) see text.

Figure 6. Abrasion numbers of a (CH3)2Si0-Si02 composite. The number represents the fraction of unaffected grains of an average diameter of 0.3 mm (in percentage) after a special abrasion test (15). The hatched area represents abrasive behavior recognized to be satisfying by test persons. The dashed line represents data that were not useful because of elasticity.

FIGURE 9 Tyrosine phosphorylation of rasGAP occurs before the transient increase in [Ca +Jj and declines before Ca + declines during activation of a,-adrenergic receptors with phenylephrine. All experiments were performed with canine femoral VSMC. Each hatched bar represents the mean values for Ca + determination in 64 cells, whereas the open bar represents mean values for tyrosine phosphorylation of rasGAP in four experiments. Maximal phosphorylation as determined by densitometric analysis was taken to be 100% and all other points were expressed as percentage of maximum. Similar results were obtained during the transient increase in [Ca +li evoked by stimulation of serotonin receptors (not shown).

Cleared (100% improvement, solid bars), excellent (90-99% improvement, hatched bars), marked (75-89% improvement, open bars), or moderate (50-74% improvement, speckled bars).

The hatch rate (cumulative percentage hateh per treatment) and initiation of hatching from eggs oflive female mayfly, Hexagenia, at 20 C are tested with different doses of particular pesticide and LC qs arc reported. 

Make a trial solution as in Table 19 and Figure 19. Remembering not to violate precedence, identify each station with a cross-hatched area. Then calculate the idle percentage 0.0182/(4 X 0.05) = 9.1%. 

Figure 1. Trailing. Trail Success (CHOICE) whether or not the snake followed an arm of the Y-maze to completion, expressed as a percentage of average overall success for all trials. TRAIL DISTANCE the distance traveled along the Y-maze expressed as percentage of the number of hatch marks crossed during the trailing episode out of the total hatch marks possible (9). Treatment 1 (T-1), Treatment 2 (T-2), Treatment 3 (T-3), Treatment 4 (T-4). Both trailing success and distance were significantly different in Treatment 1 compared to the other three treatments.
