Fats have a function in transmitting the necessary fatty acids to fish as well as being an energy source in fish nutrition. In particular, high-chain unsaturated fatty acids are needed for feeding saltwater fish. In this study, the fatty acid composition of fish oils obtained from some whole-body fish and fish by-products used in the fish-feed industry in Turkey was determined and compared with each other. Accordingly, SFA (Saturated fatty acids) ratios were in the range of 15.57-33.38% in the oils obtained from the whole-body fish and in the range of 16.3-31.89% in the oils from fish by-products; MUFA (Monounsaturated fatty acids) ratios were in the range of 24-38.69% in the oils obtained from the whole-body fish and in the range of 25.81-47.57% in the oils from fish by-products; PUFA (Polyunsaturated fatty acids) ratios were in the range of 31-36.73% in the oils obtained from the whole-body fish and in the range of 33.54-36.78% in the oils from fish by-products. Given DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) ratios which are among the most important PUFAs for nutrition, it was determined that DHA ratios were in the range of 14.08-19.10% in the oils obtained from the whole-body fish and in the range of 3.55-15.28% in the oils from fish by-products, whereas EPA ratios were in the range of 8-9.89% in the oils obtained from the whole-body fish and in the range of 2.63-15.28% in the oils from fish by-products.

Plant secondary metabolites are a group of organic compounds produced by plants to interact with biotic and abiotic factors and for the establishment of defence mechanism. Secondary metabolites are classified based on their biosynthetic origin and chemical structure. They have been used as pharmaceutical, agrochemical, flavours, fragrances, colours and food additives. Secondary metabolites are traditionally produced from the native grown or field grown plants. However, this conventional approach has some disadvantages such as low yield, instability of secondary metabolite contents of the plants due to geographical, seasonal and environmental variations, need for land and heavy labour to grow plants. Therefore, plant cell and organ cultures have emerged as an alternative to plant growing under field conditions for secondary metabolite production. In this literature review, present state of secondary metabolite production through plant cell and organ cultures, its problems as well as solutions of the problems were discussed.

This study aimed to investigate the effect of solid-state fermentation on the nutritional composition of cottonseed meal (CSM), sunflower meal (SFM) and hazelnut kernel meal (HKM). In this study, each feedstuff was divided into two treatment groups (unfermented and fermented) with five replicates. Nutritional changes in the feedstuffs were determined by analyzing crude protein, ether extract, ash, crude fiber, neutral detergent fiber, acid detergent fiber contents. Solid-state fermentation had effects on the nutritional composition in all feedstuffs. The best improvement in nutritional quality was obtained from the HKM with increasing the crude protein and decreasing the structural carbohydrates content. Fermented HKM can be considered as an alternative protein feed for soybean meal considering the nutritional composition.

An 8-week experiment was conducted to study the effect of added Natuphos® 5000 phytase in corn–soybean meal-based diets on laying hens fed different levels of crude protein (CP) (14 and 17%). Two levels of phytase enzyme were used: 0 and 600 Phytase Units (FTU)/kg feed. The experiment used 144 Hisex Brown laying hens in a 2 × 2 factorial design. Four treatments and three replicates per treatment with 12 hens per replicate were used. Egg production was recorded daily while egg weight was assessed on 13th and 14th day of each two-week period to calculate total egg mass. Total excreta were collected and approximately 10% of the amount was used for analysis after drying in a forced draft oven. The results showed no significant effect of added phytase on excreta Calcium (Ca) content, but significantly lower Magnesium (Mg) content was observed with phytase (3.54, 2.48, 3.13 and 2.75 % for hens fed 14% CP no phytase, 14% CP + phytase, 17% CP no phytase, and 17% CP + phytase, respectively). Added phytase also significantly decreased Mg excretion measured as grams/kg of egg mass (21.43, 12.47, 16.76 and 14.75 g/kg egg mass for hens of respective dietary treatments. Phytase had a strong effect on Zink (Zn) levels with 438.96, 369.17, 434.38 and 374.58 mg Zn/kg dry excreta of hens. Similar results were observed with Cu. Added phytase significantly reduced the excreta content and the excretion of Cu. The results of this experiment indicate that adding 600 FTU to laying hen diets containing 14% CP decreases the excretion of Mg, Zn and Cu without any adverse effects on the egg mass produced of laying hens.

Mastitis is considered to be the most devastating condition for the dairy farms of low and medium income countries due to its alarming impact on production and worldwide has been recognized as one of the most economically significant infectious diseases affecting the welfare of dairy animal. Chittagong is one of the dairy intensive regions of Bangladesh but comprehensive epidemiological studies addressing prevalence of and risk factors for subclinical mastitis (SCM) are scant. Therefore we aimed to approximate the prevalence of SCM in dairy cows along with the associated risk factors in dairy cows of Chittagong Metropolitan Area (CMA), Bangladesh. We included 114 cross breed (Holstein × Local) lactating cows, raised at 6 dairy farms in CMA between February to November, 2015 for this study. California Mastitis Test (CMT) was used to assess SCM at animal level. The overall prevalence of mastitis was 34.2% among the tested cows. Floor type, source of replacement cows, history of previous reproductive disorder, stage of lactation and cleanliness of floor was found significantly associated with SCM in univariate analysis. In random effect multiple logistic regression model, cemented floor was found to increase the odds of SCM by 5.03 times than that of brick floor. Similarly, cows with history of reproductive disorders had more risk of having SCM than that of cows without a history of reproductive disorders. Since the SCM is prevalent in the study area, the intervention strategy should focus on causal agent, improved management, frequent monitoring of SCM in milking cows with CMT and use of teat disinfectants; with minimal or no treatment with antimicrobial agents.

The aim of this study is to determine the consumption habits of aquatic products in Ardahan province and its districts. The study carried out between 2014 and 2015 was prepared face to face with the consumers by using a questionnaire prepared to measure the consumption habits of aquatic products. The research material consisted of data collected from 302 people by face to face survey method. When the demographic data were analysed according to the results of the study; 73.84% of the respondents were native to Ardahan and 26.15% were immigrants, 38.08% were female, 61.92% were male, the average age was 32.50 and the average monthly income was 1862.80 TL. According to the findings of the study, per capita annual fish consumption is 39 kg and per capita monthly fish consumption is 3.25 kg. The most preferred species of freshwater fish was trout (75.22%), while anchovy was found in marine fish (48.57%). While 21.98% of the participants consume fish, 18.73% chicken, 17.62% veal, 13.52% goose, 13.34% sheep, 6.67% goat meat and 4.19% turkey meat, only 1.71% prefer aquatic species such as mussels and shrimps. The important reason why fish is preferred is being healthy with 45.03%. The other most consumed aquatic products is mussel with 11.92%. It was determined that 76.49% of the consumers did not consume aquatic products other than fish. As a result, it is determined that although there is no coastline of Ardahan and the socio-economic level of the people is not high, the consumption of fish is high. The people of the region who deal with cattle as a source of livelihood prefer to consume aquatic products. In this respect, Ardahan is at the level that can be an example to Turkey.

Today’s consumers prefer foods with high nutritional value, functional properties and long shelf life. Particularly, interest in fresh fruits and vegetables, which are ready for consumption due to their healthy and nutritious nature, is increasing. However, biological activities such as respiration and transpiration cause loss of water and soluble substances in fruits and vegetables and change the gas concentration in the environment during storage and this situation greatly affects critical quality parameters such as mass loss, nutritional value and shelf life. Minimal processing, such as peeling, cutting or shredding increases the surface area of fresh fruits and vegetables, reduces the shelf life by triggering a variety of enzymatic reactions. The edible film coating is a novel packaging method that is natural, environmental friendly, economic and easily applicable. This innovative technique can be used to produce a product that is closest to fresh fruits and vegetables, maintain the desired quality characteristics, control microbiological spoilage and extend the shelf life. In addition, the use of plant-based materials in film coating applied to minimally processed fruits and vegetables attracts the consumers and increases the confidence in products. In this review, the information about the current applications of edible coating to the minimally processed fruits and vegetables and the effect of this application on some physical, chemical, sensory and microbial changes occurring in the products during the storage period has been presented.
