Reproductive Characteristics of the Common Cuttlefish (Sepia officinalis, Linnaeus, 1758) Population Distributed in the Antalya Bay النص الكامل
2022
Olgaç Güven | Mehmet Özbaş
Cuttlefish are members of the cephalopod class, that die en masse following a single breeding season (monocyclic spawning). In line with changes in environmental factors, they spent their lives in coastal areas at a depth range of 0-200 m. Although adults prefer deep areas before breeding season, they migrate to coastal areas again for breeding activity and die as a result of natural factors at the end of the breeding period. Knowledge of the life cycle and especially the reproduction phase of their life is crucial information to be able to sustainably exploit these species. Even though the coastline of Turkey, due to the variations of the environmental conditions, it's known that there are differences in reproductive characteristics among the subpopulations of the species.To determine the reproductive characteristics of the Antalya Bay subpopulation of the species, a total of 516 individuals (247 male and 269 female individuals) were examined. The mantle length of the examined individuals ranged between 45 – 177 mm. By using the morphologic characters 4 stages of sexual maturity could be observed for both sexes. Within the scope of our study, the relationship between height and weight, gonad development status (sexual maturity indices) and the number of eggs in female individuals with biometric characters were determined for the population in the sampling area.

In this study, dog traffic in the animal shelter of Sivas province was investigated both quantitatively on the basis of years and the reasons for abandonment, as well as the attitudes and behaviors of the animal owners. In the study, besides the dog traffic records of the stray animal rehabilitation center operated by Sivas Municipality, the survey data made with the owners who left their dogs there were analyzed. According to the four-year records (2019-2022), the average number of dogs staying in the Sivas Municipality Animal Shelter is 1058, while the average number of dogs collected from the street per month is 50.7, the average number of spayed female and male dogs per month is 17.33 and 33.44, respectively. The average number of adopted female and male dogs was 2.8 and 4.3 respectively and, dog deaths per month in the shelter was 21.9. Every month, an average of 15 dogs were released back to the point where they were taken after the spayed and treated at the animal shelter. In addition, a face-to-face survey was conducted with a total of 50 people who left their dogs in the shelter and 15 questions were asked to the participants, including the reasons for adopting/abandonment and form of care-feeding. As a result, it can be said that it would be beneficial to deal with the process in many different provinces with more detailed studies in terms of the ever-increasing number of dog acquisitions in the society and the prevention of their abandonment.

Selçuk Seçkin Tuncer | Sedat Behrem | Yunus Arzık | Mehmet Kızılaslan
This study aimed to investigate the body weight and some body measurements in Central Anatolian Merino sheep regarding ages and to carry out a comparative analysis between them. The study included a total of 60 animals aged 2, 3 and 4 years. The sheep were fed daily with hay, vetch, alfalfa and limited amount of concentrated feed (400 g head-1) until the pasture period, and pasture grass and mixed grass-clover hay during the pasture period. The live weights of the sheep of different ages in the farms were measured with a digital scale, and some body size were measured using a measuring tape and a measuring stick. When the live weight and chest circumference values of the 4-year-old sheep were compared with the data obtained in the other age groups (2 and 3 years old), and it was statistically significant, chest width and rump height values were found to be similar to those in the 3-age group. There were significant correlations between live weight and chest circumference, between withers height and rump height and significant correlations between live weight and chest width, body length with rump height, chest width with chest depth. In addition, significant correlations were found between live weight and chest depth, and between withers height, body length, and chest depth. Present findings revealed that the Central Anatolian Merino sheep can be beneficial in the development of meat-type sheep breeding.

Atakan Koç
Camels are known as "ship of the desert" and "beast of burden" and resistant to harsh climatic conditions. Their function has changed in the modern world and they have become a food source like other farm animal species. In the last 60 years, the number of camels, their meat and milk production in the world have increased 3.0, 4.95 and 5.0 times, respectively. In Türkiye, both Bactrian and dromedary camels are reared since F1 hybrid ♂ Tülü (Bactrian ♂ x dromedary ♀) perform better in camel wrestling, which is a unique culture of Anatolia. There are also a few farms aiming to produce camel milk and rearing young camels intensively in Türkiye. However, many practices such as calf rearing, insemination of cows, milking stimulation, milk preservation, milk quality control, milk collection and marketing and milk processing into the products are not as modern as in dairy cattle production. Although dairy camel farms in Türkiye have a higher milk production potential, since high milk prices lead to low demand for camel milk and there is only one camel milk processing facility to turn camel milk into products, farms produce far below their capacity. Processing camel milk into the products such as cheese, whey, yoghurt, pasteurized milk, kefir and ayran is still in its infancy. In conclusion, although the basis of camel rearing in Türkiye today is based on wrestling camel breeding, understanding of the benefits of camel milk on human health and the increase in demand for camel milk products suggest that this situation will change in favour of dairy camel breeding in the near future.

Md. Riyadh Arefin | Md. Ismail Hossain
Tea is one of the most important non-alcoholic beverage in the world and has been gaining further popularity as an important ‘health drink’ in view of its inferable medicinal value. In Bangladesh, commercially tea was cultivated since 1854 by establishing first tea garden Malnicherra Tea Estate in Sylhet. From 1947 to 2020, tea growing area, production and per hectare yield were increased 127.71%, 370.53% and 137.96% respectively. The major reasons behind the increasing tea productivity are extension of tea growing areas as well as cultivation of the tea clones (BT clones) released by Bangladesh Tea Research Institute (BTRI). Till now BTRI released 23 clones and 5 biclones, having average per hectare yield of 3461.67 kg. In the world, tea production, consumption and exportation have increased significantly. Unlike world condition, there is a negative relation between tea production and export in Bangladesh. From 1980 to 2020 the quantity of tea exports was decreased by 92.99%. This situation emphasizes the need for exploring alternative means by the tea industries of increasing profits from tea cultivation and tea export. As a result, researches on tea varietal improvement is needed for rapid economic growth and development of tea industry as well as to encourage tea plantation business to go ahead with more production to meet our own demand along with quality tea to flourish tea business in Bangladesh.

Phosphorous is an essential macronutrient for plant growth and development. Most of the soil is deficient in plant available phosphorous and due to economic limitations majority of Ethiopian farmers applied inadequate fertilizers. It is essential to stabilize a mechanism to access P for plants with an efficient, cheap, and eco-friendly approach for enhanced crop growth and production. The main objective of this study was to screen efficient phosphate solubilizing bacteria from tomato rhizosphere soil. Using halo zone formation on PVK agar medium, more than 400 PSB isolates were isolated from 13 rhizosphere soil samples. By evaluating SI, texture in the culture-re-culturing process, liquid medium pH change efficiency and growth rate, upmost three promising PSB isolates (K-1-29, K-10-27, and K-10-41) were selected. Incubation of the isolates in PVK broth for five days showed significant pH reduction. For instance, isolate K-10-41 showed significant pH change (4.02) which indicates the organic acid production. Isolation and evaluation of efficient phosphate solubilizing bacteria maintain soil fertility, promote plant growth, induce plant response to pathogens, reduce agrochemical consumption and promote sustainable agriculture. Therefore, these selected PSB isolates need further detailed study for taxonomic identification, plant growth promotion, host range, and phytopathogen response. Local isolation improves environmental adaptation and indigenous competition.

Investigating the nutrient composition in soil textural constituent as influenced by land use is a necessity towards a good soil conservative and management measure. In view of this, a laboratory experiment was conducted; soil samples were collected from different locations within and outside the Federal University of Technology, Akure and analyzed for basic chemical elements. The soil sampling was based on land use and six different soil samples were collected at a depth of 0-15cm. These samples included bare soil (BS), waterlogged soil (WS), maize cultivated soil (MS), cassava cultivated soil (CS), cassava-maize intercrop (CM), and mixed cropping of cassava, maize and cowpea (MC). The waterlogged soil was cultivated to rice while the bare soil was not cultivated. The soil samples were air-dried and crushed after which fractionation was carried out using a three-layer sieve to separate the soil particles into different size of 2mm to 0.5mm (Sand), 0.5mm-0.05mm (Silt) and

Duried Alwazeer | Ayhan Çiğdem
Social development is possible with agriculture. With the impact of environmental pollution, natural disasters, climate change, food security, and population growth, interdisciplinary "new agriculture" is becoming an important trend of modern agriculture. Hydrogen (H2) is the most common element on earth, making up more than 75% of the mass of the universe. Hydrogen gas is colorless, odorless, and tasteless and is considered a physiologically inert molecule and a potential source for clean energy in the future. Hydrogenated agriculture including mainly hydrogen-rich water (HRW) focuses on the molecular mechanisms underlying improved agricultural product quality. Studies have shown that H2 does not only affect plant growth and development but also affects the nutritional quality and shelf life of the fruit. Hydrogenated agriculture emerges as a promising technology for the sustainability of agricultural products in modern agricultural practices thanks to the different beneficial effects of H2 such as safety, nutritional and antioxidative properties, and high product productivity. In this review, the roles of H2 in plants, seed germination, seedling growth, root development, stomatal opening and closing, pre-harvest freshness, post-harvest freshness, and the changes caused by hydrogenated agriculture at various stages of the plant such as anthocyanin synthesis have been investigated.

The objective of the present study was to determine the relationships between animal welfare score (AWS) and milk somatic cell count (SCC) in Anatolian buffaloes. The study carried out on 39 buffalo farms of Bafra district of Samsun province of Turkey between January and March 2020. To obtain AWS data, a scale with 1 to 100 points (1-25: poor, 26-50: moderate, 51-75: suitable and ≥76: excellent) was used. Locomotion ability (LA), social interaction (SI), flooring (F), indoor conditions (IC) and effect of stockman (S) were used to be AWS parameters. Milk samples were analyzed by SCC using a portable cell counter. The SCC values were transferred to log10 base before the analyses. To assess the effects of AWS on logSCC, independent sample t-test was performed. The relations of all parameters with each other were calculated by Kendall rank correlation method and the statistical analyses were carried out by SPSS 17.0. The highest and the lowest means were obtained from SI (79.66±1.28) and F (61.79±2.51), respectively. While the highest correlation was estimated between IC and AWS (r=0.724), all AWS parameters had approximately moderate relations with AWS. Positive or negative, but insignificant correlation coefficients were estimated between any traits and logSCC. The means of SCC (136841±15522 cells/ml) and AWS (68.70±1.67) of the present study were found within the suitable thresholds. Routinely keeping the records on AWS and its components, and adding AWS data to the herd management programs was suggested to the buffalo farm owners.
