Organic animal breeding means the production of certified animal products by considering the well-being of animals without damaging the environment and without using any pesticide in a controlled manner. All aquaculture activities other than organic farming can be defined as conventional farming. Organic animal production has increased significantly annually over the past decade in the world. Dairy cattle production is examined with particular focus on the possibilities of improving the sustainability of ruminant systems and on the possible role of organic production to meet the demand of sustainability. Organic dairy cattle production can improve animal welfare, protect the environment and sustain rewarding rural life styles. Future of organic dairy cattle production will have to rely on continuous search for alternatives in nutrition, disease prevention and control that are environmentally friendly. Understanding organic dairy cattle farming from economic, ecological and animal welfare perspectives will increase the likelihood of success. In the current study, besides the basic principles of organic dairy cattle breeding that is a quite popular branch of business in recent years, the current state, weaknesses and strengths of organic dairy cattle breeding both in Turkey and the world and how organic dairy cattle breeding can be developed are discussed.

This review provides a summary of the available scientific data on selenium status in Turkey. The first reports regarding selenium status in Turkey appeared in the 1990s. Since then, much attention has been paid to selenium content in soil, cereal crops and a variety of other foodstuffs including corn, garlic, mushrooms, fresh and canned fish, meat and meat products, milk and dairy products, spice and condiment plants and honey. Previous reports by Foster and Summer (1997), Aras et al. (2001) and H?ncal (2007) reported daily selenium intake in Turkey to be 30 μg/day, 20-53 μg/day and 30-40 μg/day, respectively. However, these reports are based on limited local data and cannot be generalized for the entire country. As a result, there is still a need for further research in all seven regions and 81 provinces of the country to measure selenium content of soil, food, water and animal feed in order to determine the average daily selenium intake of animals and humans in Turkey.

Yoghurt has greater popularity among fermented milk products. The development of fruit and fiavoured yoghurt resulted in this product of major importance in markets. Garlic is a common food spice and herbal medicine for preventing of many human diseases. This study was conducted to analyze physicochemical properties of yoghurt by incorporating of garlic paste at different concentrations. Yoghurt mixtures were prepared with 0.5%, 1%, 2% and 3% garlic paste, and without garlic paste as a control. They were subjected into chemical, sensorial and microbial assessment during the storage period of four weeks. At the first week, the chemical attributes, such as ash, dry matter, total sugar, reducing sugar and pH show significantly （P 〈 0.05） higher in 3% garlic added yoghurt. On the other hand, titrable acidity was higher in yoghurt made without garlic paste. At the fourth week of storage period, 3% garlic added yoghurt received higher mean value for ash, dry matter, total sugar, reducing sugar and pH. Similarly, yoghurt made without garlic received higher mean value for titrable acidity. Garlic reduced the bacterial load in the yoghurt, as bacterial count was decreased with increase in the concentration of garlic paste. Finally, organoleptic assessment revealed that there were （P 〈 0.05） changes among the treatments in the sensory attributes. Although, yoghurt made from 1% of garlic at the first week of storage showed the best overall acceptability compared with other all treatments, such as values of ash, dry matter, total sugar and reducing sugar were 0.61%±0.05%, 14.73% ± 3%, 12.7% ± 1.57% and 1.86% ± 0.19%, respectively.

Rice flour from nine varieties, subjected to dry- and wet-milling processes, was determined for its physical and chemical properties. The results revealed that milling method had an effect on properties of flour. Wet-milling process resulted in flour with significantly lower protein and ash contents and higher carbohydrate content. Wet-milled flour also tended to have lower lipid content and higher amylose content. In addition, wet-milled rice flour contained granules with smaller average size compared to dry-milled samples. Swelling power at 90℃ of wet-milled samples was higher while solubility was significantly lower than those of dry-milled flour. Dry milling process caused the destruction of the crystalline structure and yielded flour with lower crystallinity compared to wet-milling process, which resulted in significantly lower gelatinization enthalpy.

Gentiana kurroo, a potent bitter drug plant of Indian subcon- tinent, is under threat due to over exploitation and destruction of natural habitat. We studied the murphophenology and chromosomes of G. kurtoo on both wild and field grown plants, which is very important for proper identification, conservation and domestication. Results reveal that G. kurroo is a perennial herb, and its shoot is represented by flowering branches only. Stem is modified to rhizome. The older rhizomes split into four parts at collar region appearing to fuse together at the ends and is an important diagnostic feature for crude raw materials. Two types of leaves i.e. radical leaves at the base of the plant and canline leaves on flowering shoot are present. Flowering occurs during September to October with 1-9 inflorescences per plant. Inflorescence is terminal monoca- sial cysome type. Mowers are protrandus. Anthesis starts around 7.30 am and continued till 10.0 am. Ovary is bicarpillary syncarpous unilocular. Fruit is Capsule and takes 18-20 days to mature after fertilization. Seeds are very small elliptical and 1 000 seeds weigh to 0.1275 g. Chromosomal studies made by usual squash method reveals the species is a genomic allotetreploid with n = 13. The anaphase-I segregation was normal and in none of the cells at Anaphase-I or Telophase-I could any abnor- mality like laggards, bridges, micronuclei etc. be observed.

animal agriculture has been an important component in the integrated farming systems in developing countries. It serves in a paramount diversified role in producing animal protein food, draft power, farm manure as well as ensuring social status-quo and enriching livelihood. Ruminants are importantly contributable to the well-being and the livelihood of the global population. Ruminant production systems can vary from subsistence to intensive type of farming depending on locality, resource availability,infrastructure accessibility, food demand and market potentials. The growing demand for sustainable animal production is compelling to researchers exploring the potential approaches to reduce greenhouse gases(GHG) emissions from livestock. Global warming has been an issue of concern and importance for all especially those engaged in animal agriculture. Methane(CH_4) is one of the major GHG accounted for at least 14% of the total GHG with a global warming potential 25-fold of carbon dioxide and a 12-year atmospheric lifetime. Agricultural sector has a contribution of 50 to 60% methane emission and ruminants are the major source of methane contribution(15 to 33%). Methane emission by enteric fermentation of ruminants represents a loss of energy intake(5 to 15% of total) and is produced by methanogens(archae) as a result of fermentation end-products. Ruminants' digestive fermentation results in fermentation end-products of volatile fatty acids(VFA), microbial protein and methane production in the rumen. Rumen microorganisms including bacteria, protozoa and fungal zoospores are closely associated with the rumen fermentation efficiency. Besides using feed formulation and feeding management, local feed resources have been used as alternative feed additives for manipulation of rumen ecology with promising results for replacement in ruminant feeding. Those potential feed additive practices are as follows: 1) the use of plant extracts or plants containing secondary compounds(e.g

Genetic material originating from contrasting European chestnut (Castanea sativa) populations of Greece, Italy and Spain was evaluated in a common garden test situated in Greece. The aim of the study is to device an appropriate selection strategy by identifying and conserving superior genotypes for current and future use in breeding programs. Breeding material consisted of 143 open-pollinated families growing in a common garden provenance-progeny experimental trial. Growth trait genetic parameters were estimated and response to selection was evaluated using family, within family and combined selection methods. Two models were employed for the estimation of family variance and genetic parameters. The CVA varied between 12.1% and 67% among traits and models, showing an increasing trend with age. Heritability estimates were high;however their variation with age was irregular. Selection of superior families regarding three years of measurement for height, diameter, volume index and number of leaves showed a potential gain of 12% - 25%, 12% - 28%, 33% - 73% and 21% - 49% over the mean of all plants. Genetic gain for volume index was the highest among the traits studied and the joint model used presented a more effective selection strategy. Results indicate that the experimental trial studied presented substantial genetic variation and sufficient genetic gain opportunities for quantitative traits of economic importance. These findings suggest that inferior trees can be rogued from the experimental trial and a seedling seed orchard of Castanea sativa in Greece can be established.
