A completely randomized design, with 3×3 factorial arrangement, was conducted to test various ratios of dietary protein to energy (P/E) for rainbow trout, reared in brackish water. Three crude protein levels (35, 40 and 45%) and three energy levels (370, 400 and 430 Kcal/100g) at each protein level were utilized. Semi-purified diet containing fish meal, casein and gelatin as the sources of prot...

This study aimed to improve the quality of cryopreserved goat semen for artificial insemination by the addition of cattle seminal plasma crude protein. Semen collected from cattle and centrifuged to obtain seminal plasma. Then it was purified to obtain the crude protein. The diluent used in this study was milk-yolk. There were three groups, control group without crude protein (P0), the addition...

in order to investigate the yield and quality of forage in intercropping barley and fennel, an experiment was carried out as split plot based on a randomized complete block design with three replications at the research farm of agriculture and natural resources of ramin university during growing season of 2012-2013. four treatments levels of nitrogen including: (0, 70, 140 and 210 kgn.ha-1) hav...

The objective of this study was to measure the effect of substituting different levels of shrimp meal (SM) for soybean meal (SBM) in broiler diets. In Experiment 1, 0, 10, 20, 30, and 40% of the crude protein contributed by the SBM in broiler diets was substituted by crude protein from SM. In Experiment 2, 0, 60, 80, and 100% of the crude protein contributed by SBM in broiler diets was replaced...


 This study aims to determine the effect of addition Centella leaf paste characteristics catfish nuggets and right that is able produce with best characteristics. The experimental design used Complete Randomized Design (CRD) consisting 6 levels: 0%, 20%, 40%, 60%, 80% 100%. treatment was repeated 3 times obtain 18 units experiment. data obtained were analyzed by Analysis Variance, if had ...

A meta-analysis was undertaken to examine the effects of different supplementation strategies on production beef cattle grazing tropical pastures during wet and dry seasons in Brazil. The database built with 132 studies published from 1999 2010, which accounted for 6,275 individual animals. supplements assessed were classified into three groups: energy supplement containing <20% crude protein (...

intercropping is considered as a method for increasing yield per unit and stability. in order to evaluate the effects of phosphorous biofertilizer and chemical phosphorous on fodder quality of corn (zea mays l.) and grass pea (lathyrus sativa l.) intercropping, two field experiments were conducted as factorial based on randomized complete block design with four replications at two places simult...

  Shirbot (Barbus grypus) as a species with high potential for aquaculture development recently propagated artificially in South Iran Aquaculture Research Center to extend the species diversity in polyculture system. To provide an effective economic diet for this species 9 experimental diets containing three crude protein levels (250, 300, and 350 g kg -1) and three metabolizable energy levels ...

two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...
