in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

Raman amplification of a short laser pulse by a counter-propagating pump in a plasma is simulated with a one-dimensional electromagnetic particle-in-cell code. With a large growth rate due to three wave interaction, the pump pulse is almost totally depleted and the seed pulse is amplified significantly by the transferred energy. A moving window is adopted to enhance simulation efficiency for lo...

this experiment was conducted to study of using different level and treatments of common vetch (visia sativa) on broiler performance in a completely randomized design with 10 treatments, 4 replications and 10 chicks in each, using 400 cobb500 broiler chicks. treatments were: corn-soybean meal based diet as control , and unprocessed or processed common vetch seed (water or autoclaving) each at 3...

such aabiotic stresses like water stress are some of the most important threats to the production of agricultural crops. it is almost very rare to find a place with no stress where plants can reach their potential yield. a water stress of 17 percent decrease yield, due to its effect upon fruit setting is notable. therefore, a study was conducted in bushehr agricultural research center (located ...

The depletion of important fish stocks and the degradation of marine ecosystems are common problems worldwide. Two approaches that have been widely used to restore depleted fish stocks are the implementation of harvest control rules and the establishment of marine reserve networks. Harvest control rules, underpinned by the monitoring and assessment of the status of target stocks, provide a scie...

Conventional oil reserves in Colombia are depleted. The country´s reserve-to-production ratio is estimated as 5 years. Therefore, the search for new resources and their conversion into proven essential. In this case, production of unconventional reservoirs an option Colombia. This work evaluates technical economic feasibility a Tight Oil source rock reservoir, considering parameters such fractu...
