Microbial biofilms defined as extremely complex ecosystems are considered clinically important for humans. However, the concept and significant roles of microbial biofilms in the progression of disease has seriously lagged in veterinary medicine, when compared with human medicine. Although the research on biofilms in animals is just beginning to emerge, limited studies have paid attention that microbial biofilms are clinically important in the field of veterinary medicine, especially the livestock industry, and lead to serious economic losses. In this review, the importance of microbial biofilms causing high economic losses in the livestock industry has been highlighted. Besides, the concept of microbial biofilm, their role in the pathogenesis of the animal disease, as well as diagnosis approaches and possible therapeutic strategies needed to overcome their detrimental effects in veterinary medicine, has been discussed.

Recently, Turkey has seen significant increases in animal-source foods and related raw material prices. These recent increases in prices have made it even more important to examine the prices of animal-source foods and their associated factors. This study aimed to reveal the pattern network structure and characteristics of the prices of animal-source foods and related variables for the 2010-2020 period in Turkey. To this end, a network analysis covered the prices of animal-source foods, raw material prices used in producing these foods, and some economic variables. The study results revealed that Producer Price Index (PPI) and Agricultural PPI are key variables that are highly active in the network and act as a bridge between other unconnected variables. In addition, the results of the analysis suggest that the overall network consists of highly correlated variables and that the PPI and Agricultural PPI are the two most important variables. As a result, the pattern network structure shows that economic variables have a high impact on the prices of animal-source foods. The network structure visualizes Turkey's import-substitution model in animal production and foreign dependency on feed raw materials and the market structure affected by high exchange rates. In addition, as can be understood from the positive connections between feed raw materials, the pattern network of the variables affecting the prices of animal-source foods is largely shaped by feed prices and the internal dynamics of economic variables.

In this study, the changes caused by caffeic acid phenethyl ester (CAPE) in the histopathological and biochemical parameters in the oxidant / antioxidant balance in mice with experimental cadmium toxicity were investigated. Plasma paraoxonase (PON) activity, high-density lipoprotein (HDL), low density lipoprotein (LDL), total sialic acid (TSA), total antioxidant capacity (TAC), total oxidant capacity (TOC), and oxidative stress index (OSI) were analyzed on mice’s blood samples. The results showed that cadmium intoxication triggered oxidative stress in the mice. It also lowered their PON activity alongside TAC and HDL levels and increased their TSA, LDL, TOC, and OSI levels. The histopathological examination of the liver tissues revealed focal apoptotic regions, sinusoidal occlusion, and irregularity in the cadmium group and no significant change in the other groups. These results indicated that CAPE can significantly prevent biochemical and histopathological changes due to cadmium damage.

This investigation's purpose was the evaluation of the effects of physical forms of corn and forage sources on growth performance, blood parameters, and ruminal fermentation of Holstein calves. Forty-eight Holstein calves (38.2 ± 1.2 kg of BW) were used in a completely randomized design with 4 treatments and 12 replications for 65 days. The treatments were: 1) Basal diet + mashed form corn + wheat straw (MCWS), 2) Basal diet + flacked form corn + wheat straw (FCWS), 3) Basal diet + mashed form corn+ Sugarcane bagasse (MCSB) and 4) Basal diet + flacked form corn + sugarcane bagasse (FCSB). Final body weight and daily weight gain were affected significantly by the forage (F) factor whereas no effect from C (corn physical forms) and C×F interaction were observed. Skeletal growth parameters were not affected by C, F, and F×C factors. The trial factors did not affect triglyceride and BHBA levels, while glucose level and urea were affected by C and F factors. At 30 and 60 days, Calves fed on FCWS had the highest glucose. Also, calves fed the FCSB diet presented higher urea at 30 and 60 days. Acetate acid was affected significantly by C, F, and C×F interaction (P

Bipolar damar kapama (BDK) cihazları veteriner hekimlikte artarak kullanılmaktadır. Bu çalışmada köpeklerin preskrotal açık orşiektomide bir bipolar damar kapama (BDK) cihazının kullanılmasının cerrahi süre, portoperatif ağrı ve cerrahi bölge komplikasyonlarını azaltıp azaltılamayacağının sütur ligasyonu ile karşılaştırılarak belirlenmesi amaçlanmıştır. Elektif kastrasyon amacıyla başvuran 50 orta ve büyük ırk köpek rastgele ligasyon ve BDK gruplarına ayrılmıştır. Cerrahi süre, 15. dakika, 1, 6 ve 24 saatlerde portoperatif ağrı ve 24. saatte cerrahi bölge şişlik ve morluk skorları karşılaştırılmıştır. Cerrahi süre BDK grubunda (medyan 8.30; aralık 7.03 to 10.17 minutes) ligasyon grubundan (medyan 10.18; aralık 7.47 to 12.33 dakika) daha kısa bulunmuştur. Bipolar damar kapama grubunda köpeklerin yaş (r=0.458, P=0.021) ve vücut ağırlığı (r=0.432, P=0.031) cerrahi süreyi etkilemiştir. Bipolar damar kapama grubunda postoperatif 15. dakika (P=0.001) ve 1. saatte (P=0.045) ligasyon grubundan daha düşük ağrı skorları gözlenmiştir. Cerrahi bölge şişlik skoru BDK grubunda (0.24 ± 0.09) ligasyon grubuna (0.72 ± 0.17) kıyasla düşük (P=0.034) olmuştur. Bipolar damar kapama grubunda (0.44 ± 0.13) ligasyon grubundan (1.16 ± 0.22) daha düşük morluk skoru (P=0.168) gözlenmiştir. Köpeklerin açık orşiektomisinde BDK yönteminin kullanılması geleneksel ligasyon tekniğine kıyasla daha kısa cerrahi süre ve daha düşük postoperatif ağrı ve cerrahi bölge komplikayonları ile sonuçlanmaktadır.

A 2-year-old Asian Houbara bustard was presented with a solitary well-defined, firm cutaneous mass on the hock region. Grossly, the mass protruded from the surface was located on the hairless and unpigmented areas of the right hock joint with ulceration and dried hemorrhagic foci. On microscopic examination, ulceration, hemorrhage, as well as hyperkeratosis were observed. Large round, oval to polygonal neoplastic cells extended into the dermis were arranged to form cords, trabeculae, islands or glandular-like structures without keratin pearls. These pseudoglandular structures were composed of pseudolumina containing acantholytic and detached tumor cells. Necrosis of the neoplastic cells was accompanied by infiltration of inflammatory cells particularly heterophils. Unlike pleomorphic tumor cells, mitotic count was almost frequent. No evidence of other abnormalities and tumor metastasis was found. These gross and microscopic features appeared to be suggestive of a rare histologic variant of squamous cell carcinoma (SCC), acantholytic SCC.

Musculoskeletal injuries as a kind of traumas that the human body is exposed to, adversely affect the quality of life and workforce of individuals due to restriction of movement function. This study was aimed to evaluate the effects of dose-dependent ascorbic acid administration on the repair process after gastrocnemius muscle injury in rats. In this study, 5-month-old 66 male Wistar Albino rats were used and rats were randomized to 6 groups (n = 11/group). A linear incision was made in the gastrocnemius muscle of thirty-three animals included in the muscle injury groups. Ascorbic acid (5-10 mg/kg/day) was administered to the four groups intraperitoneally just after surgery once a day. Animals were sacrificed twenty-one days later. Blood and tissue samples were used for cytokine, collagen, and histological measurements. It was found that ascorbic acid reduced serum IL-6 and muscle tissue TNF-α levels, and increased liver tissue IL-10 levels. Muscle tissue collagen levels were not statistically different between the groups in parallel with our histological results. In our study, it was demonstrated that vitamin C has effects on inflammatory mediators during muscle tissue repair to explain mechanism detailed molecular analyzes are needed.

This study was conducted to investigate the effects of choice feeding of whole wheat on performance, egg quality and income in laying hens. In the study, a total of 160-Hyline W-80 white commercial laying hens with 28 weeks old were divided into four treatment groups and fed 84 days. The treatment groups were as follows: 1) Control (C, standard commercial laying hen feed), 2) C feed+choice feeding continuously with whole wheat in a separate cup (CW), 3) C feed+weekly intermittent choice feeding with whole wheat in a separate cup (WW), 4) C feed+choice feeding with continuous whole wheat+limestone together in a separate cup (WL). Choice feeding with whole wheat methods (continuous, weekly intermittent and with limestone) caused a significant decrease in live weight change of laying hens (P0.05). In conclusion, the choice feeding of whole wheat in laying hens did not negatively affect the performance and economic parameters; however, it caused reductions in some egg quality values.

Antibiotics used on animals with food value may cause residual problems in food in terms of public health. This situation can cause serious problems in terms of human health. Raw milk, which is one of the products that are important in terms of food value, is one of the foods that are likely to contain antibiotics, even in trace amounts. In this study, raw goat's milk samples offered for sale in Ankara, Çankırı and Kırıkkale; One active ingredient was selected from the five most commonly used antibiotic groups in animals (enrofloxacin, sulfametoxazole, tilosin, penicillin G, oxytritracycline) and it was aimed to determine the residue levels of these substances in milk. For this purpose; Within one year and in two different periods, 150 raw goat milks were collected from the enterprises belonging to goat milk breeders and analyzed in terms of antibiotics specified by HPLC method. The retention times for enrofloxacin, sulfamethoxazole, tylosin, penicillin G and oxytetracycline were 7.9; 9.7; 11.5; 5.4; 7.3 min. aspect; LOD values are 1.47, respectively; 0.8; 7.51; 2.69; 8.89 µg/L and LOQ values of 4.47, respectively; 2.44; 22.78; 8.16; It was found to be 26.96 µg/L, as a result of the analysis, no antibiotic residues were detected in the goat milk samples. It is predicted that goats have a higher level of disease resistance than other milch animals, therefore, it is foreseen that the lower use of antibiotics in these animals leads to this result.
