Nihal Kayan | Nazife Gözde Ayter Arpacıoglu | Imren Kutlu | Mehmet Sait Adak
This research was conducted between 2011 and 2015 at research field of Faculty of Agriculture, Eskişehir Osmangazi University for evaluating two tillage methods (conventional and reduced), three crop rotations (wheat-wheat; wheat-fallow; wheat-chickpea) and four N levels (0, 50, 100, 150 kg ha-1). The experimental design was split-split plot with three replicates. Tillage methods were in main plots, crop rotations in subplots and N levels in sub-sub plots. The N concentration of grain and straw harvested from aboveground plant organs was separately determined using by the Kjeldahl digestion method after the plant samples were ground. Then, grain protein content, nitrogen use efficiency (NUE), nitrogen uptake efficiency (NUPE), nitrogen utilization efficiency (NUTE) were calculated. According to results, effects of tillage methods on NUE were unclear. Conventional tillage methods resulted in higher NUPE than reduced tillage in the last three years of the experiment. The NUTE was higher in reduced tillage than conventional in 2011-2012 and 2014-2015. The effects of tillage methods on grain yield were different due to the climatic conditions. Wheat-chickpea rotation had the better results for examined traits in this research. Increasing nitrogen doses increased grain and plant protein rate, however it decreased NUE and NUPE. The effects of nitrogen doses on NUTE were ambiguous. Nitrogen use efficiency and NUPE is traits that can be differed according to changeable grain yield depend on environmental conditions. Therefore, the experiments should be conducted for more than four years for revealed absolute effects both soil tillage method and nitrogen fertilization.

In this study, it was aimed to detect the antimicrobial activity of 312 Enterococcus species against Listeria monocytogenes. Antimicrobial activity was detected by agar spot and well diffusion assay. A total of 201 enterococcal strains inhibited the growth of L. monocytogenes strains based on the agar spot test. Only 44 strains showed antimicrobial activity against L. monocytogenes strains using agar well diffusion assay. Of the 44 enterococcal strains screened, 6 E. faecium (2.99%) strains had a high antimicrobial effect against indicator L. monocytogenes strains. The antilisterial activity of 6 E. faecium strains had lost after treatment of proteinase K, trypsin and pepsin. The antimicrobial compounds of these strains could be a protein or peptides nature. E. faecium strains were more active against L. monocytogenes than E. faecalis strains.

Özgün Işık | Figen Kırkpınar
Environmental pollution is defined as the disruption of normal ecological balance with emmision of various substances and energy residues as a result of human activities. Animal production is one of the major human activity that enables this emission to increase significantly. Although ruminants play an important role in the effects of animal production on environmental pollutant emissions, the effects of poultry production and broiler production are also worth considering. As in all livestock types, the main factor that has a direct impact on environmental pollutant emissions is feeding for this animal types too. High nutrient needs of broilers and production processes of feed containing these nutrients; greenhouse gas causes increased nitrogen and phosphorus emissions; consequently, they cause air, soil and water pollution to multiply. Changes in protein and amino acid levels or the use of certain feed additives in feeds affect the emission value of broiler production. In addition, the feeding methods also has an effect on these emission values. When these effects are taken into consideration, it is possible to reduce the emission values in broiler production. In this review, environmental effects of broiler nutrition examined in terms of feed production, nutrient emission by manure, presentation of feed and feed form.

In turkey, one of the most important problem of livestock’s production is insufficiency of quality forage crop, but still few forage species are cultivated. On the other hand, conservation of plant genetic resources has become an important problem in the world today. Indeed, biodiversity is an indispensable element of human life, especially food, and it is estimated that 20% of these resources will extinct by 2030. The aim of study was to determine some quality traits of white sweet clover (Melilotus alba Desr.) collected from natural flora of Bilecik province. In this study, plants were collected at the flowering stage and investigated of 17 genotypes. The determined quality traits of genotypes as fallows; crude protein, ADF, NDF, RFV, K, P, Mg, Ca and Ca/P, and these traits were noted as11.99-21.07%, 27.70-40.53%, 43.31-55.84%, 93.44-147.02, 1.300-2.807%, 0.187-0.310%, 0.127-0.350%, 0.490-1.417% and 2.05-5.92%, respectively. As a result of the study, it has been determined that the quality of the white sweet clover genotypes collected from Bilecik natural flora have been sufficient for animal feeding and have a significant potential for future breeding activities.

The belief that ancient wheat is more beneficial than common wheat has been growing trend in recent years among the consumers. The present study aims to compare bioactive peptide, allergen peptide and toxic peptide generation after gastrointestinal digestion of modern wheat (Triticum aestivum) and ancient wheat, einkorn (Triticum monococcum var. monococcum), using in silico tools. The primary sequences of both kinds of wheat were obtained from BIOPEP-UWM and UniProtKB/Swiss-Prot database. In silico digestion was applied using BIOPEP-UWM online tool. For the simulation of gastrointestinal digestion pepsin (pH 1.3) (EC 3.4.23.1), trypsin (EC 3.4.21.4), and chymotrypsin (EC 3.4.21.1) were selected and analyzed. Homology analysis was performed for each protein sequences using EMBOSS Needle program. Toxic and allergen peptides were predicted using ToxinPred online tool and Allergen FP v.1.0. The results showed that einkorn and common wheat proteins exhibited similar properties including high similarity rate (58.72-87.40%) indicating the percentage of matches between the two sequences and the identical bioactivities for peptides generated after digestion. Most of the bioactive peptides were dipeptides and the majority of them displayed more than one bioactivities including ACE inhibitory, DPP IV inhibitory or antioxidant activity, etc. Allergen peptides generated after in silico digestion were found to be similar for both kinds of wheat. In silico gastric digestion of einkorn and wheat caused toxic peptides production, but they were disappeared after in silico intestinal digestion. In conclusion, although there is a perception related to the Einkorn that is healthier than common wheat, in silico digestion of common wheat and einkorn did not support this perception.

With this study, it is aimed to reveal the effect of economically sustainable dairy goat breeding in order to provide sufficient income. For this purpose, in Çanakkale Province, which has 234.408 thousand head goats, mostly dairy goat breeding, 30 enterprises were selected through proportional sampling to determine the herd size for technical herd analysis and economic sustainability in family subsistence. The parameters obtained are milk yield (2.1 L), herd size (168.21 heads), number of animals milked (82.54 heads), milk marketing rate (96.75%). 52.30% of milk production costs are variable costs and 47.70% are fixed costs. Feed costs have the highest share in total production costs with 43.88%. In the enterprises, 68.34% of the total gross production value obtained from goat breeding is milk, 27.06% is Productive Fixture Increase and 4.60% is fertilizer income. The cost of 1 L milk in the enterprises was calculated as 1.73 TL (USD 0.36), (the average rate of 1 USD in 2018 is 4.81 TL). 1 L of goat milk price is 3 TL (USD 0.62), (Canakkale, Turkey, sales price, 2018) considering; It has been determined that the enterprises make an average profit of 1.27 TL / L per liter (42%). With the calculated parameters, a profit of 602.27 TL (125.21 Dollars) was obtained from only milk sales in a production period from a dairy goat. A family of four the poverty line, according to the Turkey Statistical Institute 2018 poverty study results are reported on a monthly 6609.000 TL. As a result of the research, the average milk yield is 2.10 L, and as a result of the calculation made considering the average milking time of 225 days and the profit obtained from it, the number of milky goats that will meet the poverty line for a family of four was determined as 131 heads.
