The aim of this study was to compare some estimation methods (LS, M, S, LTS and MM) for estimating the parameters of simple linear regression model in the presence of outlier and different sample size (10, 20, 30, 50 and 100). To compare methods, the effect of chest girth on body weights of Karayaka lambs at weaning period was examined. Chest girth of lambs was used as independent variable and body weight at weaning period was used as dependent variable in the study. Also, it was taken consideration that there were 10-20% outliers of data set for different sample sizes. Mean square error (MSE) and coefficient of determination (R2) values were used as criteria to evaluate the estimator performance. Research findings showed that LTS estimator is the best models with minimum MSE and maximum R2 values for different size of sample in the presence of outliers. Thereby, LTS method can be proposed, to predict best-fitted model for relationship between chest girth and body weights of Karayaka lambs at weaning period, to the researches who are studying on small ruminants as an alternative way to estimate the regression parameters in the presence of outliers for different sample size.

Improvement studies are conduct to increasing of productivity native sheep breeds. This studies requires being quite comprehensive and disciplined. Improvement studies to achieve the desired characteristics and in which phase of finish is crucial. In this review, we focus on obtaining and fixing type in order to need to be implemented methods in sheep and goats.

The world aquaculture industry shows a rapid increase in production recently. Depending on production methods, culture techniques and culture methods are also developing. With developing culture methods, decrease of water quality, increase of stress, decrease of food quality, increase bacterial, viral or parasite infections can suppress on growth. Lately the use of alternative materials such as prebiotics widespread to improve the health of the fish. A prebiotic is a non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or the activity of one or a limited number of bacteria in the colon. In this review, the importance and potential effects of some prebiotics are emphasized in aquaculture.

Although the digestion and absorption of lipids that are necessary for the survival of living organisms are well known in general terms, nevertheless how different lipids to be digested, how it is distributed into the bloodstream, and how to be used by the cells, are unknown issues by most non specialist people. In recent years, knowledge of lipid digestion and absorption has expanded considerably. More insight has been gained in the mechanism of action of H + pump as a transport system in fatty acid absorption. New knowledge gained on the structure-function relationship and mechanisms of action of several lipolytic enzymes in the gastrointestinal tract. This work intends to give an up to date view of lipid digestion and absorption.

The aim of this study is to determine the current situation and to analyze financial performance of rice farmers associations. The data obtained with the questionnaire method from a single rice farmers association selected as purposeful constitute material of the research. First, a general assessment of the association was conducted, and then, the financial performance of the association was analyzed using Financial Statement Analysis, Percentage Method, Trend Analysis and Ratio Analysis techniques with the aid of financial statement and income chart for the period of 2011-2013. As a result, it is determined association was founded in 2006, have a total of 220 active members and 10 women members in district and 18 villages and two university graduate staff. In addition, management and audit committee members are men, middle-aged, and primary or secondary graduated. The participation rate of members in general assembly is high. The important problems of the association are lack of solidarity among members and irregular payment of membership’s fee. In the period under investigation, decreased use of external resource, strengthening equity and increased profitability in the association were determined. It is possible to develop association as financial statue with positive relationships between association and members and activation of association in terms of marketing.

More than ninety percent of the ruminant livestock in Nigeria lies in the hands of herders who keep them under extensive and semi-intensive management systems, whereby the animals rely only on natural pasture and crop residues for survival. In this work, the mycoflora and aflatoxin levels of ten farms were determined by sampling crop residues on farms grazed by cattle. Samples of the remains of farm harvest were surface-disinfected and cultured using standard microbiological techniques while aflatoxins in the left over harvest were determined using High Performance Liquid Chromatography (HPLC) with fluorescence detection. Fungal counts in leftover harvest ranged from 1.2 x 106 to 3.8 x106cfu/g. Aspergillus flavus, A. terreus, A.parasiticus, Rhizopus sp and a yeast, Candida sp were most prevalent on all the investigated crop residues. Aflatoxin B1 (AFB1) on the crop residues ranged between 3.0 and 13.30 μg/Kg, while the levels of AFG1 were between 2.30 and 4.50 μg/Kg. Results of the present study is indicative that the accumulation of these doses of AFB1 can lead to transfer of AFB1 into cattle and subsequently into milk. So there is an urgent need to control the feeding pattern of cattle in order to protect the health of the consuming public.

In year 2013, onsite seasonal measurements have been carried out in 4 different points of Birecik Reservoir, and water samples have been taken from surface and different depths. Physical and chemical parameters have been investigated in taken water samples. The result of analysis were obtained in the following range pH (6.98-9), temperature (9.9-26 °C), electrical conductivity (275-373 µs/cm), sodium ( 19.93-22.06 mg/L), potassium (1.-2.2 mg/L), chloride/11.68-21.4, hardness (179-210 mg/L), calcium (41.66-52.9 mg/L), magnesium ((17-18.35 mg/L), sulphate (27.92-43.48 mg/L), dissolved oxygen (7.92-8.83 mg/L), chemical oxygen (0.25-8.70 mg/L), nitrate (0.62-2.48 mg/L), nitrate (0.001-0.008), ammonium (0.01-0.07), phosphate (0.001-0.031 mg/L). The samples were compared with standard values recommended by world health (WHO). The study finalize that Birecik reservoir which was declared to be a threat to the water quality should be arrested at denitrification and nutrient control to halt the degradation of the water.

Number of bread wheat cultivars have significantly increased in recent years and research on adaptation capacities of such cultivars are not sufficient in Kayseri. This study was carried out to determine high-yield bread cultivars able to adapt the conditions of Kayseri Province in 2010-11 and 2011-12 cropping seasons. A total of 42 national bread wheat cultivars were used and adaptation capacities were determined for Kayseri Region. Significant differences were observed in entire traits of the years and cultivars. Grain-fill periods of cultivars varied between 33.9-40.5 days, plant heights between 76.0-121.7 cm, number of spike per m2 between 292.5-645.8 spikes, number of kernel per spike between 17.4-43.9 kernels, 1000 kernel weights between 32.9-40.1 g, kernel yields between 153.0-278.3 kg/da, hectoliter weights between 72.8-78.4 kg and protein ratios between 9.08-14.37%. Considering the dry conditions of Kayseri region, Bezostaja-1, Gün 91, Bayraktar 2000, Dağdaş 94, Karahan 99, Tosunbey and Nenehatun cultivars were recommended for high yield and quality.

Cultivation of field crops is a challenge and risky business in sloping areas. A study was conducted as a demonstration model for the sloppy lands of Fateh Jang, Pakistan. The objectives of this study were to monitor the runoff water and soil sediment loss under different vegetative covers and slope gradients in comparison with bare fallow on each slope gradient. Three artificial slope gradients i.e., 1%, 5% and 10% were established and three crops i.e., Wheat, Gram and Lentil were cultivated on each slope gradient. Soil and water losses were quantified against each slope gradient and every cover crop for the period of 4 years. Total soil sediment losses during this study were 51% in Lentil, 30% in Gram and 25% in Wheat were lesser compared with bare soil whereas, water losses from Lentil, Gram and Wheat were 69%, 75% and 73% lesser respectively while compared with bare plots. The highest soil and water losses were monitored at 10% slope gradient following 5% and then 1% slope gradients respectively.
