The present experiment was conducted to evaluate the effects of wet feed and fermented feed on the intestinal morphology and histology of broiler chicks. A total of 360 one day old Ross 308 broiler chicks were randomly assigned (CRD) into six treatment groups. Chicks were fed: (T1) Control group of dry feed; (T2) Fed on wet feed (1:1, feed: water); (T3) 25% fermented feed + 75% dry feed; (T4) 50% fermented feed + 50% dry feed; (T5) 75% fermented feed + 25% dry feed and (T6) 100%, fermented feed throughout the experimental period. Each treatment group was replicated three times using 20 chicks per replicate. The chicks were raised at a temperature and in humidity controlled room with a 24-h. constant light and had ad. libitum access to water and feed throughout the experimental period which lasted for six weeks. The results showed that all diets containing fermented feed, especially 100%, had dependent effects on the evaluated production characteristics. The feeds had significantly (...

The main purpose of this book is to find the exact solution of homogeneous and non-homogeneous Burger equation with the boundary conditions of the types: Dirichlet, Neumann and Robin. Statistical properties of the solution such as expected value, variance, covariance and correlation coefficient are given. The solution was obtained by four steps in the first step we reduced Burger equation to non linear ordinary differential equation, in the second step is reducing the non linear ordinary equation to system of first order, in the third step we solve the system of equations to get Riccatti equation and finally reducing the Riccatti equation to Bernoulli equation. We successed to get the beginning of the wave as an earth quake or volcano. We think that our procedure is easy and simple compared with other works.

The aim of this study was to exam the small intestine effectiveness with using frankincense in the daily drinking water by measuring live body weight, weight gain, total feed intake and total feed conversion ratio as well as the wall layers' thickness of duodenum, jejunum and ileum of broiler reared under standard conditions. 300 broiler chicken, Ross 308, were distributed into five groups (3 replicate/ group) corresponding to different rates of frankincense dissolved in the daily drinking water: control (T), adding frankincense was 0.25g/ liter of water in the second treatment, 0.50g/ liter of water in the third treatment, 0.750g/ liter of water in the fourth treatment, and 1g/ liter of water in the fifth treatment. Adding frankincense continued for the duration of the experiment (5 weeks). The water containing frankincense induced a decrease in feed consumption without affecting growth rate. Chickens received frankincense, exhibited a lower feed conversion ratio than the contr...

In this paper, we suggest a new method for solving fractional initial value problems of different fractional orders. We call it hybrid Series Solution (Fractional with power, Fractional with fractional, Fractional with power and fractional). The main difference between Caputo and Riemann – Liouville formulas for the fractional derivatives as mentioned. The paper focuses on finding the exact solution of Bagley-Torvik equation and other nonhomogeneous fractional differential equations, illustrated by some Theorems and examples.

This experiments is conducted to investigate the effect of using various levels of  Dried Distillers Corn  Grains and supplemented with the Iraqi probiotic with fermentation treatment on the physiological performance of  laying hens .Atotal of   600 laying hens ( ISA Brown ) at the age of  22 weeks are used . Hens are assigned randomly on 12 treatment groups with  two replicates for each treatment , 25 hens for each replicate .The treatment  groups are as follows : T1 : The control treatment , no supplementation ( the negative control ) T2 : The control treatment with  Iraqi  probiotic ( the first  positive control ) . T3 : The control treatment with Iraqi probiotic + Fermentation ( the second  positive control ) . T4 : Dried Distillers Corn Grains"DDG 10 % . T5 : DDG 10 % + Iraqi Probiotic . T6 : DDG 10 % + Iraqi Probiotic + Fermentation . T7 : DDG 20 % . T8 : DDG 20 % + Iraqi Probiotic .  T9 : DDG 20 % + Iraqi probiotic + Fermentation . T10 : DDG 30 % . T11 : DDG 30 % + Iraqi...
