PRODUCTION PERFORMANCE AND SLAUGHTER TRAITS OF AN AUTOSEXING BROILER COMBINATION REARED EITHER SEX SEPARATE OR MIXED

performance of biological system and advanced oxidation processes (aop) treating antibiotic production industrial wastewater

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...

Effects of Chicory Powder and Butyric Acid Combination on Performance, Carcass Traits and some Blood Parameters in Broiler Chickens

The objective of this study was to determine the effect of different levels of chicory root and stem powder (CRSP) and butyric acid (BA) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. Two hundred and forty one-day-old broilers (Ross 308) were used in a completely randomized design with four treatments with six re...

Broiler performance and bone strength minimally affected by either a simulated dusk or night-interruption photoperiod

_______________________________________________________________________________ Abstract Two genotypes of male broilers were given 12 h of daily illumination; as a conventional photoperiod, with the final hour at reduced illuminance to simulate dusk, or with 1 h of the light given during the middle of the night. The lighting modifications had no significant effect on any performance variable or...

Performance of Probiotics: an Alternative to Antibiotic in Broiler Production

During the last 5 to 6 decades antibiotics have been used in an increasing amount in the field of poultry production. Antibiotics are used for treatments and as growth promoters. Now-a-days there is an increasing demand to produce antibiotic free poultry and livestock. For this purpose in my experiment the chickens were fed Probiotics at the first day before providing them any feed. In the case...
