The majority of farm households in Turkey and especially the Eastern Anatolia are still based on low-input semi subsistence agriculture and livestock production. Despite a slow decline in recent years, agriculture and livestock production remains a major employer in Turkey and it is a significant contributor to the country’s gross domestic product, GDP. Whist Turkey is one of the EU candidate countries, is self sufficient in food production and Turkish agriculture is poorly structured inefficient, with farming in the Eastern Anatolia being mainly subsistence farming. Yet, these traditional rural structures combined with poor access to low level of education and low level of off-farm unemployment problem makes the situation more complicated and unsustainable. The best way to promote sustainability, better and higher production of Eastern Anatolian and rural Turkey is to invest in the local people, villages through improved, continuing and effective agricultural and livestock programs in particular. Investment in human capital especially in the rural areas leads to more employment opportunities through entrepreneurship and innovation in organic agriculture and livestock production. A holistic approach to developing and improving supply chains could unlock the potential for sophisticated, state-of-the-art organic agriculture and livestock producers and businesses in the region to become EU and global players. Eastern Anatolian livestock producers and the farmers have the ambitions to take part in future progress because the region is naturally organic not by design but default. It is for sure that present potential of the region has not been fully determined and utilized. EU has greatly benefited from previous enlargements economically, politically and socially. When European Union (EU) and Turkish Government relations considered and accession of Turkey to EU would be the logical consequence of the previous accessions. The screening on chapter 11 (Agriculture and rural development) is one of the important criteria and Turkey is working on to meet these benchmarks.

Post-harvested blackberry, raspberry and strawberry fruits were immediately treated with 1% and 2% calcium chloride by immersion at 20 ± 1°C for 2.5 min and kept for 8 days at 0 ± 0.5°C and relative humidity (RH) 90 ± 5%. The application of calcium did not significantly effect on total titratable acidity, pH and total soluble solids. Maximum weight lost was observed for untreated berries and minimum lost was observed for fruits treated with 2% calcium chloride. After storage, ascorbic acid content was significantly higher in samples of blackberry, raspberry and strawberry fruits subjected to 2% calcium chloride dip. Treatment of blackberry, raspberry and strawberry fruits with calcium chloride had a positive effect on retention of total polyphenols content during the storage period. Depletion of antioxidant capacity of untreated fresh blackberry fruits during 8 days cold storage was 25%; raspberries and strawberries - 34 and 26 % respectively. Whereas depletion of antioxidant activity in the 2% calcium chloride treated samples of these fruits was 8, 22 and 11% respectively. In case of storage of untreated blackberry fruits content of cyanidin-3-O-monoglucoside decreased by 6.33 mg per 100 g of fruit. While, in fruit samples treated with 1 and 2% calcium chloride content of cyanidin-3-O-monoglucoside decreased by 32.06 and 11.35 mg per 100 g of fruit, respectively. Content of pelargonidin 3–O- monoglucoside increased by 2.29 mg per 100 g of the untreated blackberry fruits and by 26.87 and 8.45 mg per 100 g of fruits treated with 1 and 2% calcium chloride respectively. Change of content of cyanidin 3–O- (6 - p – coumaroyl - glucoside) in blackberry fruits was not statistically significant.

The aim of this study was investigate the effects of whole wheat scattered the litter on performance, carcass characteristics and viscosity and pH of excreta in male broilers. A total 336 male chicks (Ross-308) were randomly distributed into two dietary treatments of four replicates each. Same starter (0 to 21 d) and finisher diets (22 to 45 d) were used in both groups. All birds were given ad libitum access to feed and water throughout experimental period. From 8 to 21 days, whole wheat (10 g/bird/day) was randomly thrown on the litter in one of the experimental groups twice a day (at 0800 and 1200 h). Scattering whole wheat in the litter decreased body weight of male broilers at 21 d of age while increased at 45 d of age. Feed intake was not affected by whole wheat scatter treatment. From 22 to 45 and 0 to 45 d of age, feed conversion ratio significantly improved in group scattered whole wheat in the litter than control group. No significant differences were occurred among groups for mortality, carcass characteristics and excreta viscosity. However, pH value of excreta in group scattered whole wheat the litter showed significant reduction as compared control group. According to these results, scattering whole wheat the litter at an early stage affected the performance of male broilers positively.

Tugay Ayasan
Copra meal (CM) is an important feed ingredient and the by-product of the oil extraction from dried coconut kernels. This product, although copra meal has a moderate protein content (15-25%); because of a high cellulose content (11.63-16.00%) and some limiting amino acids (particularly lysine and methionine), limits its use as a basic source of protein in poultry due to insufficient. Copra meals are more suitable common supplements as both an energy and protein source for ruminants. In this paper, nutritional researches performed with the copra meal usage on poultry and ruminant species have been reviewed.
