Turkish Journal of Veterinary & Animal Sciences

The present study analyses the influence of various parameters on the accuracy and reliability of ROH identification procedures, as well as their relationship with inbreeding and genetic diversity in Duroc pig populations. The genotyping data of 70 Duroc pigs obtained using PorcineSNP80v1 chips were used, and the effects of LD pruning and ROH calling parameters were evaluated. It was found that the use of strict basic filters during the execution of the --homozyg command reduces the likelihood of false positives and contributes to the more accurate identification of ROH. The results show that LD pruning reduces the detection of random …

In veterinary medicine, various diseases and surgical procedures may require the isolation and hospitalization of dogs, allowing for more effective individual patient monitoring and increasing the chance of successful treatment by preventing unnecessary drug use. However, this process can be stressful. Our study aimed to determine the changes in cortisol levels, one of the primary stress hormones responsible for stress responses, in individually hospitalized dogs. In addition, epinephrine (EPN) levels, another stress marker, as well as hematological and some biochemical values were measured and vital signs were recorded. The dogs included in the study were divided into 3 groups: healthy, …

The objective was to determine how these factors affect broiler health and production efficiency. In a 35-day feeding trial, 420 day-old chicks were randomly assigned to a 2 × 3 factorial design that tested two types of acidifiers (organic versus inorganic) at three pH levels (5.8, 6.8, and 7.8), with six replicates of 10 birds per treatment. Birds were provided with acidified water ad libitum …

Evaluating The Impact Of Starch Intake On Fecal Consistency Scores In Equines, Gülşah Kaya Karasu, Hidir Gümüş

Turkish Journal of Veterinary & Animal Sciences

Horses, as monogastric hindgut fermenters, primarily engage in microbial activity in the large intestine. Although starch is not inherently harmful, excessive intake can lead to digestive disturbances and health issues due to insufficient digestion in the small intestine, resulting in overflow into the large intestine. The purpose of the study was to evaluate the use of rapid fecal analysis, including fecal score, pH, and dry matter (DM) analysis, to understand the effects of high starch intake. The study was conducted in May 2023 at a private sport horse farm in İzmir, Türkiye and involved 24 sport horses aged 4 to …

Turkish Journal of Veterinary & Animal Sciences

This study investigated the development of a meat-type sheep strain by using the differences in body structure in Kangal Akkaraman an indigenous sheep breed of Türkiye. The control group consisted of 15 male lambs born to ewes with dairy-type (DT) body structure and the experimental group consisted of 15 male lambs born to ewes with meat-type (MT) body structure. The sheep in the DT group were selected for their elegant, clear bony lines; long, thin neck; triangular body structure that widens from front to rear; and the leg length longer than the depth of the chest. In selecting sheep for …

Turkish Journal of Veterinary & Animal Sciences

In this study, the relationship between the Growth Differentiation Factor-9 (GDF9) gene polymorphism and birth weight, as well as weights on days 30, 60, 90, was investigated in Akkaraman lambs, one of the indigenous sheep breeds of Türkiye. For this purpose, a total of 314 lambs were genotyped by PCR-RFLP method for the single nucleotide polymorphism (SNP) c.260G>A in the GDF9 gene. While GG and GA genotypes were observed in the studied breed, the AA genotype was not observed. The results showed that Akkaraman lambs were in Hardy–Weinberg (H–W) equilibrium for the GDF9-c.260G>A polymorphism (p < 0.05). In this study, a significant association was observed between GDF9-HhaI polymorphism and 30th day weight and 60th day weight in Akkaraman lambs. When the animals were analyzed according to birth type, it was observed that this factor was associated with birth weight, as well as weights on days 30, 60, and 90. It is suggested that the c.260G>A coded SNP …

This study aimed to analyze the growth curve, mortality, and serum calcium (Ca) and magnesium (Mg) levels in White Mallard ducks from hatching to the prelaying period in subtropical conditions. A total of 1100 females and 270 males were raised for 146 days. At hatch, day 6 (D6), D13, D23, D34, D50, D64, D80, D94, D111, and D146, ducks were weighed separately to assess body weight (BW). Blood samples were collected at hatch, D50, D94, and D146 to determine serum calcium and magnesium levels. …

The Morphologic Structure Of Some Wing Muscles In The Common Pheasant (Phasianus Colchicus), Beste Demi̇rci̇, Murat Erdem Gülti̇ken

Turkish Journal of Veterinary & Animal Sciences

Avians use significant amounts of energy during flight that is supplied by muscles. The Common Pheasant, a member of the Phasianidae family, can fly swiftly over short distances and flies to evade predators. Pheasant species are terrestrial and have a global distribution. This investigation aimed to analyze the anatomical structure of skeletal muscles in pheasants. A cohort of 20 adult pheasants consisting of an equal number of females and males (10 each) was used. Dissections were performed on 5 females and 5 male pheasants for macroscopic evaluation. The remaining samples underwent immunohistochemical staining using an antimyoglobin antibody to measure the …

Turkish Journal of Veterinary & Animal Sciences

The sensitivity of ram semen to cryobiological procedures has motivated many researchers to investigate this issue. In clinical practice, one of the main objectives is to reduce the damage caused by freezing cells through the addition of preservatives to semen diluents. In our study, fetal calf serum (15% FCS) and 3–6 mM cysteamine were added to ram semen diluents, and their effects on semen after freeze-thawing were investigated. Semen was collected from five Kıvırcık rams using an electroejaculator and combined in equal volumes (pooling). After macroscopic and microscopic examination, the samples were divided into six equal volumes. Six study groups …

The genetic improvement of local chicken breeds is essential for sustainability and adaptability. Marker-assisted breeding can increase the response to selection; however, it requires the identification of marker associations with different traits. Therefore, the current study aimed to evaluate the association between microsatellite marker alleles and the body weight of juvenile chicks over three subsequent generations. Ten microsatellites were used to genotype four chicken lines (two selected and two randombred) across three generations. The lines included the normally feathered selected line (CE1), the normally feathered randombred line (CE2) used as a genetic control for CE1, the naked-neck selected line (CE3), …

Turkish Journal of Veterinary & Animal Sciences

Parasites are naturally present in the natural gastrointestinal fauna of marine mammals without necessarily causing any pathology. However, under various stress conditions, parasites can cause pathological disorders in the gastrointestinal system. There is insufficient information on parasite fauna of mammals living in the Black Sea waters off the Turkish coast. This study examined the stomach contents of bycaught and stranded harbour porpoises collected between 2002 and 2003 along the Turkish coast of the western Black Sea for parasitic presence. In a previous stomach content study, 450 nematode fragments (including 232 intact specimens) were occasionally collected from 33 harbour porpoises (27 …
