Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian M. Gilbert, Jossie M. Santamaria, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Lipoteichoic acid (LTA) is a cell-wall polymer in Gram-positive bacteria that stimulates inflammation. Few studies have investigated in vivo immune response to LTA, and none of the in vivo studies have been performed in birds. For this project, the pulp (a skin derivative) of growing feathers (GF) of chickens was used to investigate the in vivo effects of intradermally injected LTA. In Study 1, GF of chickens were injected with 10 μL of differing concentrations of LTA (0.1, 1.0, 10, 100 or 250 μg LTA/mL; 3 chickens/dose). Growing feathers were plucked before injection (0 h) and at 6, 24, 48, …

Avian Salmonella Enteritidis Serovar Enteritidis With Clpp Deletion Is Attenuated And Highly Immunogenic In Chickens, Xuhua Ran, Zhiyuan Yang, Guagnxi Shao, Xiaobo Wen, Siguo Liu, Hongbo Ni

Turkish Journal of Veterinary & Animal Sciences

Salmonella enterica subsp. enterica serovars are leading causative agents of gastroenteritis in humans and numerous animal species worldwide. The ClpP from Salmonella enterica is responsible for regulation under various stress conditions. We were interested in the effect of ClpP deletion mutation on attenuation of Salmonella enterica subsp. enterica serovar Enteritidis (SE) in chickens. Therefore, SM-6/Δ ClpP , deletion of the ClpP gene from a wild-type SE-6 (SM-6) strain, was generated using the phage &lamda; Red homologous recombination. Compared with SM-6, SM-6/&DeltaClpP represented a retarded growth rate and lower concentration in LB broth with and without 5% NaCl or lower pH …

Age-Related Changes In The Growth Performance, Meat Quality, And Oxidativeprocesses In Breast Muscles Of Three Chicken Genotypes, Monika Michalczuk, Artur Józwik, Krzysztof Damaziak, Zaneta Zdanowska-Sasiadek, Agata Marzec, Dariusz Gozdowski, Nina Strzalkowska

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine growth performance, meat quality, and oxidative changes in breast muscles depending on the genotype and age of broiler chickens. The experiment was conducted on 1080 chickens: fast-growing Cobb 500, medium-growing Hubbard JA957, and a slow-growing experimental line. Chickens from all genetic groups were reared on litter for 8 weeks, but from the 5th week of age, 15 chickens from each group were slaughtered every week. After slaughter at weeks 5, 6, 7, and 8 of chickens? lives, their muscles were sampled for chemical composition, fatty acid profile, and cholesterol. Contents of reduced …

Selecting Eimeria Tenella-Resistance Markers By Comparing Resistant And Susceptible Groups Of Jinghai Yellow Chickens, Jingjing Zhang, Yuxin Lin, Guojun Dai, Tingting An, Mingming Sun, Genxi Zhang, Kaizhou Xie, Jingyu Wang

Turkish Journal of Veterinary & Animal Sciences

Improving the genetic resistance of chickens to parasitic diseases is an alternative way to protect the poultry industry. To establish valid measurable in vivo parameters indicating coccidiosis resistance, 232 Jinghai Yellow chickens were randomly selected and orally infected with Eimeria tenella (1.5 x 104 sporulated oocysts per chicken). The resistant and susceptible chickens were classified based on their cecal lesion scores 8 days after infection. Ten plasma components, including antioxidant enzymes, interleukins (ILs), nitric oxide (NO), interferon-γ (IFN-γ), and β-carotene, were compared among the resistant, susceptible, and control chickens (uninfected with E. tenella). The NO, superoxide dismutase (SOD), IL17, and …

Feasibility Of Inducing Overlap Immunologic Competence In Gallinaceous Birds With Ascardia Dissimilis And A. Galli, Julie Hamilton, Thomas A. Yazwinski

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Chickens and turkeys are routinely infected with the roundworms Ascaridia galli and A. dissimilis, respectively. The current study was conducted to gather basic information on these worms and to determine whether heterologous infections (chicken worms in turkeys and turkey worms in chickens) would be successful. Chickens and turkeys were obtained at day of hatch, brooded to 7 days of age, and placed in pens (25/pen) according to infection as received at 7 days of age: homologous, heterologous and control (no infection). Bird weights, mortalities, and feed efficiencies were monitored for 3 weeks postinfection, at which time all birds were killed …

Pathological And Biochemical Studies On "Fatty Liver And Kidney Syndrome" In White Broiler Chickens Fed With Ration Including Rendering Oil, Erkan Karadaş, Harun Özer, Enver Beytut, Necmi Özdemi̇r

Turkish Journal of Veterinary & Animal Sciences

The "Fatty Liver and Kidney Syndrome" (FLKS) was induced experimentally in white broiler chickens. Eighty chickens of ten-day-old were divided into equally five groups. These chickens were fed with a daily provided commercial ration containing poultry rendering oil in a ratio of 0% in group I (control group), 5% in group II, 10% in group III, 15% in group IV and 20% in group V for eight weeks. Total mortality was 18.75%. Although group II chickens did not show significant clinical, morphological and biochemical findings, these findings were found to be significant in groups III, IV and V. In these …

The Coccidia Of The Gallinaceous Birds In Azerbaijan, Musa Musaev, Gamida Gaibova, Galiba Ismailova, Farida Alieva, Naila Iskenderova

Turkish Journal of Veterinary & Animal Sciences

In this study the data on the coccidia of gallinaceous birds in Azerbaijan were presented. Chickens and pheasants have already been examined earlier concerning the presence of Eimeria and Isospora. Peacocks and quails are studied in this aspect for the first time. The examination of the gallinaceous birds concerning the presence of crytosporidia oocysts has been also carried out for the first time. The results obtained are indicative of the presence of a few coccidian species in the gallinaceous birds which have not been detected in Azerbaijan before.

Hints On Chicken Rearing, P Smetana

Journal of the Department of Agriculture, Western Australia, Series 4

For the next few months poultry farmers will once again be concerned with rearing chickens.

A good brooder, ample space, good sanitation, plenty of water and a balanced feed are still the essentials of successful chicken raising, says P. Smetana, B.Sc. (Agric), Acting Officer-in-Charge of the Poultry Branch.
