A feeding experiment was conducted to study the response of rainbow trout juveniles fed different levels of lupin meal in diets for rainbow trout juveniles. Very limited information is available on the relationship between dietary lupin meal in rainbow trout health status. Therefore, this study aimed to determine the effects of lupin meal inclusion levels (0%, 15%, 30%, 45%, and 60%) on growth performance and health status of rainbow trout juveniles. The experimental diets (LM₀, LM₁₅, LM₃₀, LM₄₅, and LM₆₀) were formulated iso‐nitrogenous (41% crude protein) and iso‐calorific (18% crude lipid). The fish were fed twice a day. As a result, the best growth performance was observed in fish fed with LM₁₅ and LM₃₀ diets. No significant differences were detected among experimental groups in terms of body compositions. The haematological values showed significantly (p < 0.05) lower heamatocrit and mean cellular volume (MCV) in the group of LM₆₀ compared with the other groups. For the other haematological parameters such as haemoglobin, red blood cell and mean cellular haemoglobin studied in the present study no significant differences were observed (p < 0.05). The lupin meal included groups showed significant reduction in total protein (TPROT), triglyceride (TROG), cholesterol (CHOL), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) compared with the control group (p < 0.05). The inclusion of lupin meal did not cause any changes in glucose (GLU), glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) between the treatment groups (p < 0.05). In conclusion, lupin meal might be used in rainbow trout diets up to 30% without any malnutrition effect on growth performance, haemotological and serum biochemical parameters.  相似文献   

Effect of weight and apllied force on the friction coefficient of the spunlace nonwoven fabrics     

Nazan Avcio?lu Kalebek  Osman Babaarslan 《Fibers and Polymers》2010,11(2):277-284

Friction force that can be defined as the forces resisting relative to the movement between two surfaces contacting with each other plays an important role in textile industry. During usage, the fabrics continue to friction to the textile or the other surfaces and because of this problem fabric surface structure deteriorates. Therefore, most of the scientists have been designed different methods in order to estimate surface properties and friction of fabric before their usage. In this study, friction experiments have been performed by designed and manufactured two different systems which work as a horizontal platform and inclined plane. It has tried to investigate friction properties of polyester nonwoven fabric samples which are produced by spunlace methods (air laid and spunlace bonding) with different weights. While the selected fabric samples weight increase, it has been seen that a low friction force occurred because of more stable structure. And also, it has been observed that the higher vertical force (load) applied on the specimens the lower the coefficient of friction. These results shows that both measurement methods have similar tendencies based on the analyzed results.  相似文献

Potential of the indigenous desert grasses of the Arabian Peninsula for forage production in a water‐scarce region     

A. E. Osman  M. Makawi  R. Ahmed 《Grass and Forage Science》2008,63(4):495-503

Indigenous perennial grasses are widely distributed in the Arabian Peninsula. Their survival under limited rainfall and grazing suggests a potential role as grassland species and for rehabilitation of degraded rangelands. Forage productivity, seed production and water‐use efficiency (WUE) was determined over 2 years for four indigenous grasses: buffel grass (Cenchrus ciliaris L.), dakhna (Coelachyrum piercei Benth.), da’ay (Lasiurus scindicus Henr.) and tuman (Panicum turgidum Forssk.) together with one exotic species, rhodes grass (Chloris gayana Kunth) in the central region of the United Arab Emirates. Three irrigation treatments were used: R1 (1858–6758 m³ ha^?1 year^?1), R2 (929–3379 m³ ha^?1 year^?1) and R3 (464–1689 m³ ha^?1 year^?1). Buffel grass had the highest dry‐matter (DM) yield under all irrigation treatments. The average DM yield of buffel grass was 14·6 and 15·1 t ha^?1 in the 2 years which was significantly higher than that for the other grasses with dakhna having the lowest DM yields. The WUE of 0·7 and 0·8 kg DM m^?3 in the 2 years for buffel grass was significantly greater than for the other grasses. Buffel grass showed the highest increase in WUE in both years when the irrigation was reduced from treatment R1 to R3. The results suggest that the desert grasses of the Arabian Peninsula, such as buffel grass, could be useful grass species in reducing the use of scarce irrigation water provided that seed production can be increased.  相似文献   

Determining the Energy Usage Efficiency of Walnut (<Emphasis Type="Italic">Juglans Regia</Emphasis> L.) Cultivation in Turkey     

Mehmet Fırat Baran  Osman Gökdoğan  Halil İbrahim Oğuz 《Erwerbs-Obstbau》2017,59(1):77-82

The aim of this study is to reveal the energy balance of walnut in Central Anatolian Region in Turkey. This study has been conducted at the walnut cultivating facilities during the 2014–2015 production season in K?r?ehir, Konya, Nev?ehir and Ni?de provinces of Central Anatolian Region in Turkey, where walnut cultivation is intense. In the study, a total of 28 walnut cultivation facilities, yielding walnut, have been selected through Neyman method and surveys and observations have been performed in these facilities. The agricultural input energies and output energies used in walnut cultivation have been calculated to define the energy use efficiency. According to the study findings, the energy inputs in walnut cultivation are calculated respectively 17,851.33?MJ ha^?1 (74.40%) chemical fertilizer energy, 2229.87?MJ ha^?1 (9.29%) fuel energy, 1640.64?MJ ha^?1 (6.83%) irrigation water energy, 1539?MJ ha^?1 (6.41%) machine energy, 508.02?MJ ha^?1 (%2.11) chemical energy, 180.35?MJ ha^?1 (0.75%) human labour energy and 43.33?MJ ha^?1 (0.18%) farm manure energy. Production outputs have been calculated as 14,679.52?MJ ha^?1. Following the energy calculations, the output/input ratio, specific energy, energy efficiency and net energy calculations have been calculated respectively as 0.61, 30.20?MJ kg^?1, 0.03?kg MJ^?1 and ?9313.02?MJ ha^?1. Benefit-cost ratio was calculated as 1.88, by dividing the gross value of production by the total cost of production per hectare in walnut production.  相似文献   

Adaptation of endemic mediterranean Sternbergia candida Mathew Et T. Baytop in the continental climate of central anatolia     

Bilal Gurbuz  Neset Arslan  Khalid Mahmood Khawar  Arif Ipek  Ercument Osman Sarihan  Sebahattin Ozcan  Iskender Parmaksiz  Semra Mirici 《Scientia Horticulturae》2009,123(1):3536-103

Sternbergia candida is an important endemic bulbous plant with beautiful white flowers. It grows on the rock slopes of Baba mountains under Lebanon Cedars in the Mugla province of Turkey with Mediterranean climate. The plant is vulnerable and endangered due to illegal collection for local and foreign flower industry. Fast developing tourism industry and rapid urbanization has also shown negative implications on its population. The study reports three years successful adaptation results of S. candida in the continental climate of Ankara in the Central Anatolia. Four groups of bulbs based on diameter (>2.45, 2.15–2.44, 1.85–2.14 and <1.84 cm) were collected from its natural habitat during March, April and May 1998 and were evaluated for frequency (%) of emergence, mean number of leaves per plant, mean plant height, frequency (%) of flowering, frequency (%) of fruit setting. mean number of bulbs per plant, and mean diameter (cm) of regenerated bulbs. All categories of bulbs could be multiplied and adapted successfully with variable frequency of fruit setting. However, the highest fruit set was recorded from 2.15–2.44 cm April collected bulbs. This indicated that the bulb diameter and collection time had clear implications on multiplication, propagation and adaptation of the plant.  相似文献   

Computer aided data acquisition tool for high-throughput phenotyping of plant populations

Background  

The data generated during a course of a biological experiment/study can be sometimes be massive and its management becomes quite critical for the success of the investigation undertaken. The accumulation and analysis of such large datasets often becomes tedious for biologists and lab technicians. Most of the current phenotype data acquisition management systems do not cater to the specialized needs of large-scale data analysis. The successful application of genomic tools/strategies to introduce desired traits in plants requires extensive and precise phenotyping of plant populations or gene bank material, thus necessitating an efficient data acquisition system.  相似文献
