Effect Of Acute And Repeated Noise Exposure On The Behaviour And Lipid Peroxidation In Brain Tissue Of Male And Female Mice, Gabriella Korsós, Kinga Fodor, Annamária Kiss, Anna Blázovics, Sándor György Fekete

Turkish Journal of Veterinary & Animal Sciences

Despite the increasingly obvious sex differences, male animals are still predominantly used to study stress and related disorders. The aim of this study was to evaluate the effects of repeated noise stress in female and male mice. In the experiment, 12 male and 12 and female SPF/VAF 6-week-old Crl:CD1(lcr) mice were used. After 5 days of acclimatization all animals were placed in the open-field for three consecutive days where each mouse spent 10 min daily without any noise treatment in order to get used to the circumstances of the test. On day 9 to record baseline behaviour the animals were …


Comparison Of Performance Parameters, Stress, And Immunity Levels Of Native Andcommercial Layers Reared In Different Cage Densities In Turkey, Uğur Özentürk, Ahmet Yildiz Jan 2021

Comparison Of Performance Parameters, Stress, And Immunity Levels Of Native Andcommercial Layers Reared In Different Cage Densities In Turkey, Uğur Özentürk, Ahmet Yildiz

Turkish Journal of Veterinary & Animal Sciences

In this study, production performance, stress, and immunity levels of native Turkish and imported commercial laying hens were investigated in two different cage densities. In the trial, a total of 06 groups were formed by using two different cage densities (312.50 and 468.75 cm$^{2}$/hen) on each of 03 different laying hen hybrids of Isa Brown (IB), Atak-S (A-S) and Novogen White (NW). The trial was carried out with 09 replicates in each group having 10 birds per replicate making 540 birds in total. Water and feed were provided as ad libitum. It was found that the native hybrid showed lower …


Assessment Of Changes In The Saliva Cortisol Level Of Horses During Different Waysin Recreational Exploitation, Boguslawa Dlugosz, Tomasz Próchniak, Monika Stefaniuk-Szmukier, Marta Basiaga, Jaroslaw Luszczynski, Magdalena Pieszka Jan 2020

Assessment Of Changes In The Saliva Cortisol Level Of Horses During Different Waysin Recreational Exploitation, Boguslawa Dlugosz, Tomasz Próchniak, Monika Stefaniuk-Szmukier, Marta Basiaga, Jaroslaw Luszczynski, Magdalena Pieszka

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to evaluate the saliva cortisol levelsof recreational horses dependent on the type of horse activity. A total of 68 horses were included in the experiment and divided into groups according to recreational activity, type of horse, age, term of saliva collection, and sex. Saliva samples were obtained from each horse at 3 measurement points: in the morning (6 a.m.), in the evening (6 p.m.), and immediately after work. The overall analysis shows that the term of sample collection, recreational activity, and age influence cortisol concentration. The diurnal concentration of saliva cortisol does not differ …


The Effect Of Stocking Density On Stress Reaction In Broiler Chickens During Summer, Mehmet Kenan Türkyilmaz Jan 2008

The Effect Of Stocking Density On Stress Reaction In Broiler Chickens During Summer, Mehmet Kenan Türkyilmaz

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to investigate the effect of stocking density on the heterophil to lymphocyte ratio (H:L), blood corticosterone concentration, immune response, and some performance parameters in broilers during summer. In all, 300 1-day-old commercial broiler chicks (Ross 308) were housed at densities of 15, 20, and 25 birds/m^2, with 2 replicates of each. H:L ratio and blood corticosterone concentration were used to measure the level of stress in the birds. Newcastle disease (ND) antibody titers were also analyzed to determine the level of immune response with a commercial ELISA kit. Mean H:L ratio, corticosterone concentration, and …


Protein Profile And Plasmid Content Of Lactococcus Lactis Subsp. Lactis Ll52 And Lactococcus Lactis Subsp. Cremoris Lc79 Strains Under Several Stress Conditions, Rahmi̇ Lale, Çağla Tükel, Mustafa Akçeli̇k Jan 2007

Protein Profile And Plasmid Content Of Lactococcus Lactis Subsp. Lactis Ll52 And Lactococcus Lactis Subsp. Cremoris Lc79 Strains Under Several Stress Conditions, Rahmi̇ Lale, Çağla Tükel, Mustafa Akçeli̇k

Turkish Journal of Veterinary & Animal Sciences

Differences in the protein and plasmid content of 2 Lactococcus lactis strains, L. lactis subsp. lactis LL52 and L. lactis subsp. cremoris LC79, under the stresses of high and low temperature, osmotic shock, and low pH were determined. We identified 3 new proteins with molecular masses of 16.0, 29.4, and 45.0 kDa as high temperature stress response specific in strain LL52. High temperature stress did not cause any changes in the protein content of strain LC79. Proteins that were specific for salt stress and low pH stress responses ranged between 16.0 and 40.5 kDa, and 24.8 and 107.5 kDa, respectively, …


Effects Of E And C Vitamins On The Growth And Immunity Of The Angora Goat Kids Exposedto Stress, Hali̇t İmi̇k, Meli̇h Aytaç, Behi̇ç Coşkun, Hati̇ce Fi̇danci Jan 2000

Effects Of E And C Vitamins On The Growth And Immunity Of The Angora Goat Kids Exposedto Stress, Hali̇t İmi̇k, Meli̇h Aytaç, Behi̇ç Coşkun, Hati̇ce Fi̇danci

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the effects of administration of vitamin E and C on the live weight gain, anti-body levels against Brucella melitensis (Rev.1) vaccine and liveability of Angora goat kids separated from their mothers at the age of 21 days, and then exposed to stress. Forty kids were used in this study. They were divided into four groups having ten kids per group. This study was conducted with the control group (+) in which the kids were not separated from their mothers until the wean-ing period, a group(-) which was exposed to stress and being …
