(11) Hens also produced more (P less than .05) eggs when maintained under cyclic temperature conditions, although this observation was tempered by the fact that fewer hens were broody.
(12) Genetic changes in average clutch length, total days lost from broodiness, fertility, and response to cold stress did not have a major influence on semen production in the turkey.
(13) In addition, egg quality, broodiness, floor egg production, and poult weight data were obtained in Experiment 2.
(14) During moderate cooling, vasoconstriction in the feet and wattles of broody hens (but not of non-broody hens) freed non-nutrient blood flow for redistribution to the brood patches.
(15) Synthesis and release rates of prolactin and growth hormone (GH) in the anterior pituitary of laying and incubating broody chickens (Nagoya breed) were determined by a disc electrophoretic technique after in vitro incubation of anterior pituitaries with a labeled amino acid.

(17) The RBC1 turkeys had linear increases in the percentage of broody hens during the first 84 and 180 days of production, the average length of the broody period, and the total number of days lost to broodiness during the 180-day period.
(18) When expressed as a deviation from RBC1, positive quadratic curvilinear changes were observed for E turkeys for number of clutches and broody periods, and days lost to broodiness during the first 180 days of production.
(19) Thoracic skin cooling from 35 to 25 degrees C decreased Tths less in broody than in non-broody hens.
(20) An assessment was made of the possible role of hypothalamic 5-hydroxytryptamine (5-HT) in the regulation of prolactin secretion in broody bantam hens.

Example Sentences:
(1) Since fingernail creatinine (Ncr) reflects serum creatinine (Scr) at the time of nail formation, it has been suggested that Ncr level might represent that of Scr around 4 months previously.

(3) Following central retinal artery ligation, infarction of the retinal ganglion cells was reflected by a 97 per cent reduction in the radioactively labeled protein within the optic nerve.
(4) Based on several previous studies, which demonstrated that sorbitol accumulation in human red blood cells (RBCs) was a function of ambient glucose concentrations, either in vitro or in vivo, our investigations were conducted to determine if RBC sorbitol accumulation would correlate with sorbitol accumulation in lens and nerve tissue of diabetic rats; the effect of sorbinil in reducing sorbitol levels in lens and nerve tissue of diabetic rats would be reflected by changes in RBC sorbitol; and sorbinil would reduce RBC sorbitol in diabetic man.
(5) In all groups, there was a fall in labeling index with time reflecting increasing tumor size.
(6) Hepatic enzyme elevations were more dramatic after blunt trauma, reflecting greater hepatocellular disruption.
(7) This modified endocrine activity in brook trout may reflect adjustment to adverse external ionic conditions.
(8) It is concluded that in the mouse model the ability of buspirone to reduce the aversive response to a brightly illuminated area may reflect an anxiolytic action, that the dorsal raphe nucleus may be an important locus of action, and that the effects of buspirone may reflect an interaction at 5-hydroxytryptamine receptors.
(9) We assessed changes in brain water content, as reflected by changes in tissue density, during the early recirculation period following severe forebrain ischemia.
(10) Many problems at the macroscopic level require clarification of how an animal uses a compartment of suite of muscles and whether morphological differences reflect functional ones.
(11) Defibrotide prevents the dramatic fall of creatine phosphokinase activity in the ischemic ventricle: metabolic changes which reflect changes in the cells affected by prolonged ischemia.
(12) The combined results suggest that any possible heterogeneity in the L-CAM genes is not reflected in the size of either the mRNA or protein.
