A trial was conducted to study the effect of two dietary electrolyte balances (dEB, dEB=Na+K-Cl, meq/100g) on the productive performance, quality of eggs and physiological status of Hy-Line Brown laying hens. 128 hens were allocated in cages (4 hens/cage) and divided into two experimental groups (16 repetitions/group). The diets were isoproteic and isocaloric with different electrolyte balance ...
this experiment was conducted to evaluate and compare antibiotic, organic acid, probiotic and prebiotic effects on performance, egg quality and blood metabolites in commercial laying hens. the experiment was a completely randomized design with 160 laying hens strain hy line (w-36) from 32 to 42 weeks of age with 5 treatments and 4 replicates of 8 hens each. the experimental treatments consisted...
Two experiments were designed and conducted to evaluate the effect of tallow and the nutritional value of millet and the effect of substituting millet for corn on the performance of laying hens. In the first experiment, the nitrogen corrected true metabolizable energy (TMEn) of tallow and millet was determined. Also the digestibility of dry matter (DM), protein, fat and crude fiber of millet wa...
An experiment was conducted to study the effects of carbon tetrachloride (CCl4) on post-peak performance and serum enzymes of Hy-Line W-36 laying hens from 32-36 weeks of age. The experiment was carried out with a total of 192 laying hens in a completely randomized block design. During the experiment laying hens were allocated to 4 groups consisted of T1) no CCl4 as control diet, T2, T3 and T4)...
In an experiment with 288 laying hens from a commercial strain (Hy-line W36), the effect of partial and total replacement of soybean meal, corn grain, wheat grain and wheat bran with dried tomato pulp (DTP) on performance and egg quality was determined. In the 12 week experiment, hens (27 to 38 weeks of age) were allocated to four dietary treatments being: DTP0, DTP50, DTP100 and DTP150 of 72 b...
The purpose of this study was to evaluate the effect of cholestyramine and lovastatin, lipid-Iowering agents, upon egg quality, reproductive performance, plasma lipids and egg yolk cholesterol levels of Shaver laying hens. Twenty-sixweeks-old hens were fed basal diet without animal products containing 0.2% cholestyramine (COLl), 0.3% cholestyramine (COL2) or 0.005% lovastatin (LOV) for 6 weeks....
This study was conducted to evaluate the effects of dietary supplement-ation of rosemary essential oils (REO) and zinc (as zinc sulfate) on performance, egg quality traits, and some serum biochemical metabolites of laying hens. A total of 144 44-weeks-old Lohmann LSL-Lite laying hens were randomly allocated into four treatments, each comprising six replicates of six birds. The first group was s...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
In this experiment, the effect of prebiotic Bio-Mos® (MOS) and types of feed formulation (total and digestible amino acids) were evaluated on performance and the small intestine microflora in laying hens for a duration of 10 wks. A total of 168 Hy line W-36 laying hens, with an initial age of 73 wks, were randomly allocated to 4 dietary treatments, 7 replicates and 6 birds in each replicate. Th...
