2014
Osman Olgun | Alp Önder Yıldız
This study was carried out to determine the influence of diets including different levels of protein and supplemented with probiotic-enzyme mixed on performance parameters and eggshell quality in laying quails. Japanese quails (n=120), 10 wk of age, were divided into 6 dietary treatment groups and the experiment lasted for 10 weeks. In each experiment group there were 5 replicates, and in each replicates there were 4 birds. Six diets, arranged a factorial design with three protein levels (16, 18 and 20 (control) %) and two levels of supplemented probiotic-enzyme mixed (0.0 and 1.0 g/kg) were used. Dietary crude protein levels and supplementation of probiotic-enzyme did not effect on the body weight gain, egg mass, feed intake, feed conversion, cracked egg yield, specific gravity and shell strength. However, egg production, eggshell thickness and eggshell weight were significantly increased by the addition of probiotic-enzymes mixed. Egg weight in group containing 18% crude protein was significantly higher than the containing 16% crude protein group. Results of the present study indicated that laying quails should be fed 18% crude protein and 1.0 g/kg of supplemental probiotic-enzyme mixed improved egg production and eggshell quality.

Besseboua, Omar | Ayad, Abdelhanine
This study aims at investigating the effect of Saccharomyces cerevisiae (SC) supplementation on reproductive performance, haematological parameters and fertility of rabbits under Algerian conditions. The animals were divided into three groups and received the same feed ration during the experimental period. The control group received a basal diet without feed additives (Group#0) and the two yeast SC groups received 0.3 and 0.6 g/day per head (Group#1 and Group#2, respectively). Semen and blood samples were collected for determination of semen parameters and haematology. The weights of rabbits treated with SC 0.3 g/day were statistically significantly different (P< 0.05) from the control groups and group treated with SC 0.6 g/day. There were significant differences between the treatment groups for (RBCs), haemoglobin (HGB), haematocrit (HCT) and mean corpuscular haemoglobin (MCH) values, with higher values in rabbits supplemented with SC 0.3 g/day and 0.6 g/day, compared to those in the control group. The scrotal diameter did not differ between the dietary treatments. When compared with the control group, feeding rabbits graded levels of SC resulted in an increase in the average semen volume, mass motility and individual motility at day 51 of the experiment. On the other hand, the sperm concentration was significantly lower (P< 0.05) in rabbits supplemented with SC 0.3 g/day and 0.6 g/day during the two months compared to that in the control group. The spermatozoa mortality rate was lower for the rabbits supplemented with SC 0.3 g/day and 0.6 g/day (15.7% and 11.4%, respectively), compared to that in the control group (24%). In conclusion, this study has shown that inclusion of SC 0.3 g/day and 0.6 g/day in the diets of rabbit has positive effects on body weight and sperm analysis. Moreover, it increases the level (RBCs), haemoglobin (HGB), haematocrit (HCT) and mean corpuscular haemoglobin (MCH).

Genetic diversity present in gene pool is an important determination for breeding programs, and characterization is useful of building crop plant collections primarily based on the knowledge of the presence of valuable genes and traits. Developing successful varieties for increasing the future yield and quality of tomato depend mainly on the genetic diversity of parents used in the breeding program. Molecular characterization of 21 tomato genotypes used in in Pakistani breeding program was studied using random amplified polymorphic DNA (RAPD) markers. Total 102 bands were amplified among 21 genotypes using 20 RAPD primers. Overall 73.5% polymorphism was shown as 75 out of 102 loci were polymorphic. High degree of divergence between varieties was indicated by low level of monomorphic bands. The number of PCR products per primer varied from 2-8 with an average of 5.1 bands per primer. Primer GL J-20 and GL C-09 produced maximum number of bands whereas the primers GL A-09 produced the lowest. The polymorphism per RAPD primer ranged from 50% to 100% with an average of 73.5%. The accumulative analysis of amplified products generated by RAPD’s was enough to assess the genetic diversity among the genotypes. The information would be helpful for formulating future breeding and genome mapping programs. This study will also work as an indicator for tomato breeders to evolve varieties with genetic diverse back ground to achieve sustainability in tomato production in the country.

Bajan, Bartłomiej | Mrówczyńska-Kamińska, Aldona
The purpose of this paper was to assess the prevailing relationships in the supply structure of the agribusiness sector in European Union countries over the years. The study focused on 25 European Union countries (Cyprus, Luxembourg and Malta were excluded) to address the changes in the supply structures of agriculture and food industries, the two major components of agribusiness. The study was of a dynamic nature. Although the study period was 2000–2014, this paper only presents the figures for the first and the last year, i.e. 2000 and 2014. The main focus was on drawing conclusions on the trends observed which proved to be relatively stable in the years covered. The input–output analysis was used by aggregating the sectors of the economy for a better transparency of the inference process. As shown by this study, EU countries at higher development levels witness a decline in the share of the chemical industry in the mix of goods and services supplied to agriculture. Conversely, less developed countries saw that ratio increase. Also, the share of goods supplied to agriculture from the fuel and energy sectors goes up in most EU countries. As regards the food industry, this study observed high shares of agriculture, services and self-supply in the supply structure of EU countries. This analysis extends the existing knowledge on the relationships in the structure of materials supplied to the agribusiness because in addition to agriculture itself (which was addressed by similar studies found in literature) it takes account of the food industry. Moreover, based on long-term observations, it endeavors to capture the prevailing relationships in several countries at a time.

Abbas Moghanizadeh | Mehdi Neshat
Saffron, the dried stigmas of Crocus sativus, is extremely appreciated for its extraordinary color, taste and aroma. At the present time, nearly all the saffron harvest and post harvest processes are carried out manually. To increase the quality and development of economic role of saffron, it is essential to go beyond the traditional method of harvest of saffron. Considering that saffron components terminal velocities are different, a separator is planned and constructed to separate stigma from other parts of saffron flower. This separator is designed on the basis of aerodynamic and physical properties of saffron flower. The purpose of this study is to analyze the performance of a saffron separator for different air flows to increase the level of automation and efficiency of post-harvest operations. The results show that the maximum stigma separation happens when the air flow speed in outlet B is 3 m/s. finally, this data will be applied to find the optimum areas of outlet B and D, as two main parameters which have significant effect on the efficiency of saffron separator.

In this study, it was aimed to demonstrate the effect of humic acid applications on some morphological, physiological and biochemical characteristics of eggplant genotypes (Burdur Merkez, Burdur Bucak, Kemer and Giresun) irrigated with the irrigation water with a high content of heavy metal and determined previously salt tolerance levels. In studies conducted in controlled greenhouse conditions, eggplant seeds germinated in the growth substrate a mixture of peat and perlite and the seedlings were transplanted into pots at 20 days after sowing. Plants when they are 4-5 true leaves, 3 different humic acid levels (0, 500, 1000 ppm) have been applied and 7 days later after this application began to be watered with 3 different irrigation water comprising a mixture of various doses of heavy metals (control: 0 ppm; I. Mixture: 0.2 ppm 5 ppm to 0.01 ppm Cd + Cu + Pb + 2 ppm Zn, II. mixture: +0.02 ppm 0.4 ppm Cu 10 ppm Pb + Cd + 4 ppm Zn). Field capacity level for the plants 40 days after quenched with water after which time they were harvested and samples for analysis were performed. In the study plants were investigated for shoot and root fresh weight, shoot and root dry weight, shoot and root length, leaf area, chlorophyll and MDA level of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) enzyme activities All genotypes are adversely affected by heavy metal applications. In parallel to increase the dose, heavy metal mixtures led to a reduction in values of fresh and dry weight of shoot and root, stem and root length, leaf area of eggplant genotypes. MDA and antioxidative enzyme activities increased in plants irrigated with water containing a mixture of heavy metal. Humic acid applications had a positive effect on reducing of the limiting effect of heavy metal stress on growth and development. As a result, compared to sensitive genotypes Giresun and Kemer, salt tolerant genotypes Burdur Merkez and Burdur Bucak showed much better resistance to abiotic stress factor which consists of heavy metal applications. The obtained results; formed also an opinion about that plants evolved similar strategies for resistance to abiotic stresses such as salinity, drought and heavy metal stress.

Sage, which belongs to Labiatae family and contains essential oils, is a typical Mediterranean plant. Being an important and one of the biggest species of this family, sage is said to be named being inspired by the word "Salveo" which means “saver” or “healer” in Latin. Salvia genus is represented by about 900 species on earth. There are 97 natural species of this genus in Turkey’s flora. There is dormancy in seeds of Salvia genus and having mucilage-like seed-coats is an inhibiting factor for germination. Seed germination studies of these species are of great importance in determining production strategies. This research is carried out at 25/15°C, 12 hours in light and 12 hours in dark environment to determine the effects of various germination applications (ethylene, gibberellin, PEG 8000, salicylic acid and seaweed) and pre-treatments (pre-drying, pre-cooling and untreated) in four species (S. fruticosa, S. officinalis, S. pomifera, S. tomentosa). These trials were conducted at the Department of Field Crops Laboratory of Adnan Menderes University according to completely randomized design with three factors with three replications. Important differences were observed about the germination rate and germination power among the species.

An experiment was conducted to determine the effect of different combination calcium sources and particle size on performance and egg shell quality in layer hens. In the experiment, 198 brown laying hens at 44 week of age were randomly assigned into 11 treatments groups. The experimental diets consisted of different calcium sources (Fine limestone, large limestone, large oyster shell and large egg shell) and their different combination. The experimental unit consisted of a groups of three hens, thus each treatment was replicated six times. Different calcium sources and particle size addition to the laying hens diet had no significantly effect on body weight gain, egg production, egg mass, feed intake, feed conversion ratio, egg specific gravity, egg shell weight, egg shell thickness and egg shell breaking strength but egg weight had significantly affected by the treatments. The significantly highest egg weight was found in laying hens fed with 50 % fine limestone and 50 % large limestone. Dietary different Ca sources had a significant effect on Ca, P and Mg as mineral contents of eggshell and tibia. In the present study, when dietary large calcium sources (limestone, oyster shell and egg shell) had no effect on performance and eggshell quality parameters in laying hens. However, dietary containing at least 50 % large calcium sources had positive effect on mineral contents of tibia.

Meat and meat products are the basic building blocks of nutrition and are recognized as good sources of high biological value proteins, group B vitamins, minerals as well as some other bioactive compounds. The trend today is the development of novel food for special health use, called functional food, to promote human health and well-being of consumers. The trends are based on either reducing the content of unhealthy substances (like salt) or improving the content of substances with healthy benefits (like probiotics). Thus, it may also change the perspective of consumers towards meat products which associated with coronary artery disease. Meat is an ideal structure for probiotic microorganisms. Probiotic meat products are obtained by addition of probiotic to fermented meat products. These probiotic meat products are offered both healthy and improved taste and flavor, but also as safe food to consumer. Thus, when these probiotic meat products ensure flavor and nutritional to consumers, additionally they have a positive impact on their health.
