An experiment with 720 pullets was conducted to investigate the effect of dietary energy levels of pullet and dietary energy and fat of laying ration on subsequent performance parameters during 14-20 and 22-44 weeks of age. In the first period, white leghorn pullets were fed with two diets of low and high density energy (2600 and 3200 Kcal ME/kg). In the lating period (second period), birds, in...
a total of 1440 arian chicks were used in this study to determine the effects of diet formulation methods on performance and blood parameters of arian chicks. eight diets were arranged in a 2×2×2 factorial design with 2 methods of energy expression (apparent (amen) and true (tmen) metabolizable energy corrected to n equilibrium), 2 methods of amino acids content of feeds (total (taaf) and diges...
The effects of dietary lipid and carbohydrate, and their interaction, on growth performance and body composition of juvenileblunt snout bream Megalobrama amblycephala were investigated. Fish were fed one of eight isonitrogenous (32% crude protein) diets containing 4% or 7% lipids and 25%, 30%, 35%, or 40% carbohydrate for nine weeks. Weight gain, feed conversion ratio, protein efficiency ratio,...
Background and Objective: Because of the importance of the role of energy in the world and nonrenewability of fossil fuels and caused environmental issues by these fuels in recent years, many studies have been conducted to find an appropriate alternative to fossil fuels in different countries of the world. Biofuels such as (biodiesel and bioethanol) have been introduced as one of the most desir...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
Sixty Ghezel ewes (age 3.5 years) were used to study the effect of different nitrogenous supplements in flushing ration on reproductive performance. Experimental treatments were divided in five groups: group A: urea; group B: soybean meal (SBM); group C: corn gluten meal (CGM); group D: barley grain and group E: control or basal diet (no flushing). The four flushing rations had nearly the same ...
Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...
the efficiency of oil extraction from oil seeds is affected by seed harvesting time, drying methods, seed storage conditions and finally the means of seed transportation to the factory. to determine the grain moisture content at harvest and its effect on seed while on drying trails, (employing different canola dryers), a study was conducted in mazandaran province in 2009. a factorial complete ...
the study examined gender analysis of energy use for rice production in north central nigeria using a sample of 60 rice farmers. an analysis of gender relations provides the information on the different conditions men and women face, and the different effects that policies and programs may have on them. simple descriptive statistics were used to analyze the data. energy efficiency and energy pr...
