The aim was to investigate the growth of certain non-carcass components and hind limb tissues using allometric coefficients in Saanen goat kids reared under natural and artificial systems and slaughtered at 80 days or 120 days of age. 42 Saanen kids were used in the study [(24 artificial reared kids (SA-80: 12 kids, SA-120: 12 kids), 18 natural reared kids (SA-80: 9 kids, SA-120: 9 kids)] for determination of indicated parameters. The effects of rearing system were not significant in weights of non-carcass components and hind limb tissue compositions, which indicate that, even though they were fed with milk replacers, artificial reared kids can have similar growth performance when they are slaughtered at similar age with natural raised kids. However, slaughter age had significant effect on many non-carcass components, since the weight of the organs increases in parallel with animal’s live weight. It is seen that allometric growth of non-carcass parameters, except skin and testis in both rearing groups and stomach and intestines in natural rearing, was slower (b<1) than EBW of kids slaughtered at 120th days of age. This result shows that when the Saanen kids will be slaughtered at later ages, the increase of live weight will be mainly due to the increased saleable carcass components. Additionally, tissue compositions showed that muscle growth continued rapidly (b=1.494 for natural and b= 1.251 for artificial reared) in both groups on the 120th day of age. This situation reveals that prolonging the fattening period with Saanen kids can increase meat production for both rearing systems. On the other hand, it is observed that the amount of both subcutaneous and intermuscular fat increased more rapidly at the 120th day of age in both groups. Therefore, the optimal slaughter age at 120th days should be determined by taking into account the possible increasing amount of fat.

This study was carried out to investigate external and internal egg quality traits of different quail lines housed in a multitier cage system. The study was performed on eggs of three different lines of quail as wild type, recessive white and black cross-line stock raised for commercial production. All flocks in the experiment were housed in the same environmental conditions for quail and fed the same diets during the experiment. A total of 60 eggs from each quail line were used to determine internal and external egg quality traits. The eggs from cross-line black coloured quails had significantly greater weight (P<0.01) and it needs more force to crack significantly than the other eggs to break (P<0.012). The black line of quails had significantly greater egg shell thickness than the other line quails (P<0.001). The white line quail eggs had significantly lowest egg length and highest shape index values (P<0.001, P<0.001). The egg yolk of white lines had a significantly lighter yellow than wild and black lines (P<0.003). In conclusion, it seems that the eggs of black coloured quails were relatively superior to wild and white coloured quail groups.
Determination of the effect of green extraction solvents on the phenolic acids and flavonoids of propolis
(Bursa Uludağ Üniversitesi, 2022-07-26) Kekeçoğlu, Meral; Sorucu, Ali
Propolis is an important bee product with many biological activities due to its containing phenolic compounds. The phenolic compounds of propolis vary depending on the plant source, season, altitude, extraction method and solvent. The present study investigated the extraction of phenolic compounds from propolis according to solvent factors. The propolis samples were extracted in four different solvents, which were water, ethanol-water (70%), dimethyl sulfoxide (DMSO), and L-lysine (8%), and were analyzed 36 phenolic compounds by HPLCDAD. Statistically significant differences in solubility of the phenolic compound at various levels were detected among the solvents (P <0.05). Only water and ethanol-water (70%) more successful than the other solvents were determined in the extraction of phenolic components of propolis. Phenolic acids generally dissolved higher in water, while flavonoids dissolved higher in ethanol were determined. Certain phenolic compounds were detected only in some of the propolis extract: syringic acid and daidzein in water, vitexin, rutin, and epigallocatechin in ethanol, and emodin in DMSO. Consequently, the chemical content is affected significantly depending on the extraction solvent of propolis. Therefore, it is essential to determine the extraction solvent and analyses of propolis before application for therapeutic purposes.
First record of Gordius sp. (Nematomorpha: Gordioidea) from Balıkesir Province, Türkiye
(Bursa Uludağ Üniversitesi, 2022-07-26) Schmidt-Rhaesa, Andreas; Yıldız, Kader; Çırak, Veli Yilgör; Bursa Uludağ Üniversitesi/Veterinerlik Fakültesi/Parazitoloji Anabilim Dalı.; 0000-0003-0570-2514
The nematode phylum Nematomorpha contains organisms which are also known as horsehair worms or Gordian worms. We report here a male specimen of Gordian worm from a horse farm in Balıkesir province, Turkey. The body of the specimen was brown in color and the length was about 38 cm. After fixed in ethyl alcohol (80%) scanning electron microscopic (SEM) observations were carried out. Based on macroscopic and SEM findings the specimen was identified as Gordius sp. As merely little data is available on these organisms in Turkey, our finding will contribute to the existing knowledge in terms of the local diversity of this taxon.
Immunohistochemical investigation of TNF-a expression in sheep and goat lung paraffin blocks infected with natural respiratory syncytial virus

Respiratory Syncytial Virus (RSV) is an important viral agent of sheep and goat respiratory tract infections. RSV usually replicates in airway epithelium, inducing proinflammatory cytokines and chemokines. In this study, it was aimed to investigate TNF-α expression in natural RSV-infected sheep and goat lung paraffin blocks by immunohistochemical method. The material of the study consisted of 29 lung paraffin blocks (19 sheep and 10 goats), which were admitted to Etlik Veterinary Control and Research Institute with the suspicion of pneumonia from Ankara and surrounding provinces between 2015 and 2020. Histopathological findings such as degeneration and desquamation in the bronchial and bronchial epithelium, fibromuscular hypertrophy, hyperplasia in the peribronchial lymphoid tissue, cell infiltration in the interalveolar septum were common in sheep and goat lung paraffin block tissues. Immunohistochemically, RSV reaction was not statistically significant in sheep and goats in bronchial and bronchial epithelium and cell debris, bronchial glands, interalveolar septum inflammatory cells and cytoplasm of alveolar macrophages (p> 0.05). A statistically significant increase in TNF-α expression was determined in goat lung paraffin blocks compared to sheep (p<0.05). In conclusion, an increase in TNFα expression was detected in native RSV-infected sheep and goat lung tissue. It is thought that the results of the study will contribute to the treatment of sheep and goat respiratory tract RSV infections.
