Six hundred Ross male x Cobb female eggs were administered either 0.9% saline (control) or 600 microg/kg egg weight PYY in ovo at Day 18 of incubation. On day of hatching, 210 birds from each treatment group were randomly placed by sex into pens. Body weights at placement were not different between treatment groups. Average chick body weight and adjusted pen feed conversion ratios were improved by PYY in ovo treatment at 7 d posthatch (165.7 vs. 170.2 g, P<0.02; and 1.55 vs. 1.49, P<0.04, respectively). No significant differences between treatments were noted for these parameters at 21 or 42 d of age. These results suggest that in ovo treatment of broiler chicken eggs with gastrointestinal hormones that increase intestinal nutrient absorption, such as PYY, may enhance chick performance.}, number={9}, journal={POULTRY SCIENCE}, author={Coles, BA and Croom, WJ and Brake, J and Daniel, LR and Christensen, VL and Phelps, CP and Gore, A and Taylor, IL}, year={1999}, month={Sep}, pages={1320–1322} } @article{gore_qureshi_1997, title={Enhancement of humoral and cellular immunity by vitamin E after embryonic exposure}, volume={76}, ISSN={["0032-5791"]}, DOI={10.1093/ps/76.7.984}, abstractNote={In the present study, the amnion of turkey and chicken embryos were injected 3 d prior to hatch with different levels of vitamin E (VE). In Experiments 1 and 2, turkey embryos received 10, 20, and 30 IU of VE. In Experiment 3, broiler embryos received 10 IU VE. In all three experiments, sham-injected control embryos (0 IU VE) received 300 microL of saline. In Experiments 1 and 2 (turkey embryos), 20 and 30 IU of VE reduced (P < or = 0.05) percentage hatchability below that of controls. At hatch, poults exhibited a dose related increase (P < 0.05) in plasma VE levels. Mean BW gain up to 35 d and relative bursa of Fabricius and spleen weights were not different among treatment groups. When challenged at 7 d posthatch, total (P < 0.05) and IgM (P < 0.08) anti-SRBC antibodies were higher in 10 IU VE poults than in controls. Immunoglobulin G levels did not differ among the treatment groups. Poults in the 10 IU VE group had higher (P < 0.002) numbers of Sephadex-elicited inflammatory exudate cells, as well as a greater percentage of phagocytic macrophages (P < 0.0001). Additionally, the numbers of SRBC per phagocytic macrophage were greater (P < 0.001), than in control poults at 4 wk of age. In Experiment 3, chick embryos exposed to 10 IU VE, exhibited no differences in hatchability, BW gain, or bursal and splenic weights from the sham-exposed group. However, total and IgM antibody responses against SRBC were greater (P < 0.01) in the 10 IU VE group at 7 d postinjection. A secondary SRBC challenge given at 14 d after primary injection resulted in higher total (P < 0.07) and IgG (P < 0.04) antibody responses in the 10 IU VE chicks than in the controls. Similarly, broiler chicks (10 IU VE) had more Sephadex-elicited abdominal exudate cells (P < 0.07), and greater macrophage phagocytic potential (P < 0.0001). In ovo VE exposure (10 IU) also increased nitrite production (P < 0.04) by chick macrophages. The results from this study demonstrated an enhanced antibody and macrophage response and suggest that in ovo exposure with VE may improve posthatch poult and broiler quality.}, number={7}, journal={POULTRY SCIENCE}, author={Gore, AB and Qureshi, MA}, year={1997}, month={Jul}, pages={984–991} } @article{qureshi_gore_1997, title={Vitamin E exposure modulates prostaglandin and thromboxane production by avian cells of the mononuclear phagocytic system}, volume={19}, ISSN={["1532-2513"]}, DOI={10.3109/08923979709007669}, abstractNote={The production of Prostaglandin E2 (PGE2) and Thromboxane B2 (TXB2) by turkey blood monocytes and a chicken mononuclear phagocytic cell line MQ-NCSU after exposure to vitamin E (VE) was examined. Turkey embryos were exposed in ovo to 0 and 10 international units (IU) of VE; blood monocytes were collected at 2 weeks of age and cultured. MQ-NCSU macrophage monolayers were exposed to 0, 0.1, 0.25, and 0.5 IU VE. The monocyte/macrophage cultures were exposed to 1 microgram/mL bacterial lipopolysaccharide (LPS). Non-stimulated parallel cultures were maintained as controls. The PGE2 and TXB2 levels were quantitated in culture supernatants by a competitive ELISA. Blood monocytes from the 10 IU VE poults produced lower PGE2 levels as compared with the 0 IU VE controls. Upon stimulation with LPS, monocytes from the 10 IU VE group exhibited levels of PGE2 that were higher than the 0 IU VE group. Levels of TXB2 were not quantitated in the poult blood monocyte culture supernatants. The PGE2 and TXB2 levels in the supernatant of the VE treated MQ-NCSU macrophage cultures were lower than the 0 IU VE controls. Stimulation with LPS resulted in increased PGE2 and TXB2 production by the VE-exposed macrophages. The results from this study suggest that in ovo or in vitro exposure with VE may either upregulate or downregulate PGE2 and TXB2 production by monocytes/macrophages, and that this production may be dependent upon the exposure to a variety of external stimuli and/or the state of macrophage activation.}, number={4}, journal={IMMUNOPHARMACOLOGY AND IMMUNOTOXICOLOGY}, author={Qureshi, MA and Gore, AB}, year={1997}, pages={473–487} }
