The Effects of Beak Trimming and Claw Reduction on Growing and Early Laying Parameters, Fearfulness, and Heterophil to Lymphocyte Ratios
… procedures. During the preliminary experiment, heterophil to lymphocyte ratios did not consistently differ significantly between treatments. The RC birds had significantly lower body weight, except from 3 to 6 wk and had significantly lower feed consumption from 8 to 18 wk. The 1-day beak …

COMPARATIVE EVALUATION OF 1H NMR SPECTROSCOPY AS A NOVEL TOOL FOR ASSESSING STRESS WITH TRADITIONAL METHODS OF BLOOD CORTICOSTERONE LEVELS AND HETEROPHIL LYMPHOCYTE RATIO IN BROILER CHICKENS (GALLUS DOMESTICUS)
… corticosterone (CORT) and increased circulating heterophil/lymphocyte (H/L) ratios. The lack of consistency between studies measuring CORT and H/L ratios results in some skepticism when using them to quantify stress and animal welfare in the poultry industry. 1H Nuclear Magnetic Resonance …

Influence of egg size, eggshell quality, and hatch and placement times on the performance of broiler chickens
… measured through 35 days of age. Hematocrits, heterophil/lymphocyte ratios, plasma proteins and glucose were measured through 11 days of age. Broilers from large vs small eggs were 10% heavier and had lower mortality at 49 days of age. Chicks that were held for extended time in the hatcher had …

Effects of lead ingestion on the immune function in quail
… was marginal evidence that lead increased the heterophil to lymphocyte ratio in quail fed com. Com decreased the cell-mediated immune response to an intradermal injection of phytohemagglutinin. Corticosterone suppressed cell-mediated immunity more than lead. The primary total antibody response …

Efeitos do óleo essencial de Elionurus muticus (Spreng.) Kuntze na indução anestésica e no manejo de tilápia do Nilo em diferentes pH da água
… pH 8.5 had a reduced hematocrit. Leukocyte and heterophil counts were highest at pH 7.0, especially in anesthetized fish. Anesthesia at pH 7.0 reduced plasma total protein and albumin levels. Hyperglycemia was observed in unanesthetized fish at pH levels of 5.5 and 8.5. Plasma total cholesterol, …

The effects of dietary β-glucan supplementation on performance and immune response of broiler chicks during an Eimeria challenge
… peripheral blood was collected to determine heterophil to lymphocyte (H:L) ratios, and small intestinal sections were sampled to evaluate relative gene expression. The addition of β-glucan had no influence on growth. Dietary β-glucan supplementation modulated the expression of interleukin …

Street-wise : does prey abundance buffer black sparrowhawks (Accipiter melanoleucus) from the negative health impacts of urbanisation?
… was evaluated through their immune response (Heterophil/Lymphocyte ratio in white blood cell counts), body condition (based on morphometric measurements) and blood parasite infection (presence and abundance of Haemoproteus and Leucocytozoon). Trends in diet composition along a gradient of …

Molekulare Bindungsstudien herzmuskelspezifischer Protein-Varianten mittels Rasterkraftspektroskopie (AFM)
… Analyse von Bindungseigenschaften homo- und heterophil interagierender Desmoglein-2- und Desmocollin-2-Proteinfragmente. Das bedeutet, dass insbesondere auch Kardiomyopathie-assoziierte Varianten dem jeweiligen Wildtyp gegenüber gestellt wurden, um funktionale Unterschiede aufzudecken. Diese …

Stress response and habituation as influenced by nutritional and thermal factors in dwarf and normal chickens
… neonatal stages was evaluated. In both stages, heterophilia and lymphopenia were noted and post-hatching heterophil to lymphocyte (H/L) ratios declined in a quadratic manner with age. Feed restriction elicited a similar stress response, as indicated by H/L ratios in dwarfs and normals with the …

Intestinal Inflammation Model Inducing Gut Leakage by Different Methods in Broiler Chickens Using FITC-d as a Marker
… dissolution of tight junctions. Additionally, heterophil/lymphocyte ratio was significantly increased and relative spleen and bursa of Fabricious weight ratios were significantly decreased in DEX-treated chicks. These results provide a robust measurement model for enteric inflammation model in …

Physiological and behavioral responses of genetic lines of chickens to physical and auditory stimuli
… appeared to create a stress as measured by heterophil/lymphocyte ratios and production of antibody to sheep erythrocytes. Behavioral and production criteria showed that chicks responded favorably toward socialization and playbacks as measured by feed conversion and comfort scores, with the …

HABITAT USE AND THE EFFECTS OF DISTURBANCE ON WINTERING BIRDS USING RIPARIAN HABITATS IN SONORA, MEXICO
… in the two disturbance levels, but the mean heterophil/lymphocyte ratio in the blood of sampled birds showed increased levels of physiological stress in disturbed sites. A more experimental approach is needed to determine the specific cause of the stress expression in …

Innate Immunity in Chickens: In Vivo Responses to Different Pathogen Associated Molecular Patterns
… or PGN in the pulp of GF resulted in increased heterophil levels in the blood and local tissue as well as smaller increases in macrophage proportions in the tissue. However, injection of PGN also resulted in the rapid recruitment and sustained presence of high levels of T and B lymphocytes at …

Linear Additivity of Multiple Concurrent Environmental Stressors' Effects on Chick Performance, Physiology, Histopathology, and Behavior
… G, F, and G/F fell, and CV-G rose, linearly. D-7 heterophil %/lymphocyte % (h/l) rose due to all stressors and linearly with order. Only C affected blood total-cell fraction. Experiment II. Hubbard chicks were studied via 2$\sp{6}$-factorial of A and B (as Exp. I), C (0 or 6 $\times$ 10$\sp{5}$ …

Validating Body Condition Indices As Indicators Of Individual Quality: Does Condition Explain Intraspecific Variation In Reproductive Success And Survival Among Crimson Finches (Neochmia Phaeton)?
… concentration, total plasma protein, and heterophil to lymphocyte ratio. I describe the variation in these indices and find that many vary by sex and breeding stage, and to a lesser extent by year, age and time of day, concluding that these covariates need to be controlled for when …

Effect of neonatal heat stress on growth, mortality and blood characteristics of juvenile broilers exposed to high ambient temperature
… T₄ and total plasma protein during late heat. Heterophil to lymphocyte ratio was lower in the early heat stressed group than in the early control group during the second day of late heat exposure These results indicate that thermotolerance can be induced by exposing broiler chicks to 35.0 to …
