Turkish Journal of Zoology

Estimating ecological flows (EFs) in rivers is crucial for meeting the Water Framework  Directive (WFD) 2000/60/EC goals. To develop an EF model, it is  essential to use biological indicators to reliably record the impacts of human-induced  alterations on aquatic ecosystems. The adaptability of fish to annual flow variability  makes them a significant biological quality element (BQE). Consequently, using fish  as bioindicators is a powerful tool for assessing the impact of changes in the  hydrological regime on the natural communities within a river system. The new index  of the ecological status of fish communities (NISECI) is a methodology developed in  Italy …

Chlorella Vulgaris Measurements Using Full-Spectrum Goniometer For Optically Complex Inland Water Monitoring, Pinar Gürbüzer, Uğur Murat Leloğlu

Turkish Journal of Zoology

Rising environmental stressors, including climate change, nutrient loading, pollution,  and anthropogenic impacts, have made the continuous monitoring of lake water  quality increasingly essential. While in situ methods offer high precision, satellite-based remote sensing is essential for capturing large-scale, long-term changes and  accessing remote or extreme environments. To complement these approaches, we  developed a cost-effective in situ optical measurement system specifically designed  for optically complex inland waters. T he instrument enables detailed optical  characterization across scattering angles from 0° to 160° and wavelengths between  423 and 728 nm, covering both visible and near-infrared regions. Initial validation was  performed using monocultures of …

Could Gene Editing Increase Chicken Resistance To Avian Influenza?, Alta Crane

Research on Capitol Hill

Avian Influenza is a viral infection that causes outbreaks of "bird flu," greatly affecting avian health. Influenza A virus (IAV) relies on various host factors for efficient replication. Previous studies in human cells have identified four genes as critical host factors required for IAV infection. To investigate whether similar host– virus interactions exist in avian species, we utilized gene editing systems to generate knockout fibroblast cell lines targeting those four genes and then applied these techniques to germ cells.

Determination Of Cortisol Concentrations Using Different Biomarkers In Dairy Goats During Pregnancy, Fatma Mi̇ra Güven, Erkan Pehli̇van

Turkish Journal of Veterinary & Animal Sciences

Pregnancy is considered one of the most physiologically stressful periods in mammals. In the present study, serum and hair cortisol concentrations were measured in nine female Akkeçi goats, including five primiparous (1.5 years old) and four multiparous (3.5 years old), to evaluate chronic stress during pregnancy. Hair samples were collected in October, November, and December following the introduction of bucks to the herd and within the first 12 h postpartum (corresponding to the 1st, 2nd, 3rd, and 7th sampling times). Hair samples were not collected in January, February, or March (the 4th, 5th, and 6th sampling times) due to insufficient …

Effects Of Zinc-Reinforced Clinoptilolite On Hematological Parameters, Igg Levels, And Enzyme Histochemistry In Fattening Lambs, İhsan Kisadere, Muhi̇tti̇n Zengi̇n, Özkan Demi̇rbaş, Mehmet Faruk Aydin

Turkish Journal of Veterinary & Animal Sciences

The study aimed to determine the effects of zinc-reinforced clinoptilolite supplementation to the diet on selected hematological parameters, serum immunoglobulin G (IgG) concentrations, and enzyme histochemical characteristics in fattening lambs. For this purpose, 40 healthy male lambs were randomly allocated into five equal groups: control (C; n = 8), natural clinoptilolite (NC; n = 8), zinc (ZN; n = 8), natural clinoptilolite plus zinc (NCZN; n = 8), and zinc-reinforced clinoptilolite (ZNRC; n = 8). All animals were housed in individual pens, and the supplementation period continued for 42 days. Blood samples were collected before the trial (day 0) and …

Comparison Of The Mars And Xgboost Algorithms For Predicting Body Weight In Kalahari Red Goats, Louis Thobela Tyasi, Cem Tirink, Kwena Mokoena, Hasan Önder, Uğur Şen, Demet Çanga Boğa, Tolga Tolun, İsmai̇l Gök, Yüksel Aksoy, Lütfi̇ Bayyurt, Ömer Faruk Yilmaz

Turkish Journal of Veterinary & Animal Sciences

Estimating goat body weight from morphometric traits is essential for growth monitoring, health management, and welfare. Accurate weight informs nutrition, clinical interventions, and mating decisions. In this study, the MARS and XGBoost algorithms were used to estimate the live weight of Kalahari Red goats based on body measurements. A dataset containing body length (BL), birth type (single, twin, or triplet), withers height (WH), rump height (RH), and heart girth (HG) information for 200 goats was used in the training and testing of the models. The performances of the models were evaluated with the goodness-of-fit criteria. XGBoost showed a performance of …

Hatchability And Nestling Viability In An Extremely Short-Beaked Pigeon Breed, Türker Savaş, Hakan Erdem, Cemi̇l Tölü

Turkish Journal of Veterinary & Animal Sciences

The selection of hobby animals for breeding by enthusiasts is often based on aesthetic considerations, which can have a negative impact on the animals’ biology. Furthermore, “extreme traits” that deviate from ancestral norms, such as short beaks in pigeons, can be detrimental to the animal’s welfare. Beaks perform many essential functions, such as facilitating feed intake and eggshell breaking. The present study investigates possible hatching problems and the nestling viability of short-beak pigeons through a study of the breeding records of Mısıri (short beak), Baska (medium beak), and Turkish Dönek (normal beak) pigeons, as well as data from one breeding …

Effect Of Feeding Levels With High Micronutrients On The Reproductive Performance And Plasma Progesterone Concentration In Early Gestation Sows, Kewalin Kongngern, Liang-Chou Hsia, Shu-Ping Su, Wantamas Jantasin, Jai-Wei Lee

The Thai Journal of Veterinary Medicine

This experiment investigated the effect of feeding levels with high micronutrients on the reproductive performance and plasma progesterone concentration in early gestation sows. Thirty-six first-parity sows (Landrace × Yorkshire × Duroc), with an initial average body weight of 160.85 kg, were randomly allocated to four dietary treatments during early gestation: Treatment 1) fed 1.5 kg/day (days 1-30), Treatment 2) fed 1.5 kg/day with 1.7 times the vitamins and minerals (total vitamin E 150 IU) (days 1-15) and fed 1.5 kg/day (days 16-30), Treatment 3) fed 1.5 kg/day with 1.7 times the vitamins and minerals (total vitamin E 150 IU) (days …

Conditioned Feed Aversion As A Means Of Conditioning Livestock To Avoid Consuming Toxic Plants Growing In South Africa : An Overview, Leendert D. Snyman, Frederick D. Provenza

Poisonous Plant Research (PPR)

Significant economic losses to the livestock industry are caused by the ingestion of toxic plants in South Africa, among which the most dangerous ones are Moraea pallida (geeltulp), Urginea/Drimea sanguinea (rooislangkop), Senecio latifolius (Staggers Ragwort), and Geigeria ornativa (vermeerbos). Conditioned feed aversion is a potential means to address this issue. Treating animals with an aversive substance along with an extract of the sensory characteristics of a specific plant conditions animals to avoid the plant. Geigeria ornativa, unlike the other three plants, is non-aversive. Following treatment for aversion, the induced aversion fades with time and eventually breaks down. Continuous exposure …

A Case Study Of Suspected Sheep Losses Due To Chokecherry Not Death Camas, Kevin D. Welch, Clint A. Stonecipher, Stephen T. Lee, Daniel Cook, Benedict T. Green

Poisonous Plant Research (PPR)

Death camas (Zigadenus paniculatus) is a toxic plant often associated with poisoning cases in livestock, especially in sheep, in the spring on mountain foothills. Consequently, when sheep are found dead in mountain foothills, and death camas is present, it is often implicated as the potential cause of death. However, this may be over simplistic as there may be other plants that may also contribute to, or are the cause of, death in sheep. In this study, we present a case of approximately 200 sheep out of a band of 400 that died within 24 hours of beginning to …

Susceptibility Profile And Multiple Antibiotics Resistance Of Escherichia Coli, Klebsiella Spp., And Enterococci From Small-Scale Cattle Farms In Tennessee, Goodness Olakanmi, Maureen Nzomo, Bharat Pokharel, Abdullah Mafiz, Agnes Kilonzo-Nthenge

Food and Animal Sciences Faculty Research

Antimicrobial resistance in food–animal environments threatens sustainable production and public health, yet small farms remain poorly characterized as potential reservoirs of antimicrobial resistant bacteria. To address this, we investigated the prevalence and antimicrobial resistance profiles of Escherichia coli, Klebsiella spp., and Enterococcus spp. from small-scale cattle farms in Tennessee, USA. Methods: Over one year, 153 environmental samples (soil, manure, water) were collected from 17 farms. Target bacteria were isolated and confirmed using selective agar, biochemical tests, and PCR, and tested against 12 antibiotics using the Kirby–Bauer disk diffusion test. Multiple Antibiotic Resistance Index (MARI) and multidrug resistance (MDR) profiles …
