[ 1 ] - The Effect of Energy Sources and Levels on Performance and Breast Amino Acids Profile in Cobb 500 Broiler Chicks
The present study conducted to investigate the effect of energy sources and levels on performance and breast meat amino acids profile in Cobb 500 broiler chicks. A total of 600 1-day-old Cobb 500 broiler chicks with an average weight of 39 ± 0.50 g were randomly divided into five treatments. Each treatment was further divided into four replicates. Chicks were fed a basal diet based on corn and ...
[ 2 ] - Energy Type and Amount in the Diets of Broiler Chickens: Effects on Performance and Duodenal Morphology
The present study was conducted to investigate the effects of dietary energy sourcesandlevels on performance and small intestinal morphology in broiler chickens. A total of 600 one-day-old broiler chicks were randomly divided into five treatments with four replicates each. Chicks were fed diet based on corn as main energy source and energy level based on Cobb 500 manual instruction considered c...
[ 3 ] - Effect of Some Acidifiers on Gastrointestinal Tract Characteristics and Performance of Broiler Chickens
The effects of Selko-pH (S; 1 mL/L drinking water); Termin-8 (T; 2 kg/ton feed) and Neogermicin (N; 2 L/ton feed) on gastrointestinal tract (GIT) pH, microbial population, ileal digestibility and broiler performance were investigated. The lowest feed intake (FI) was attained by chickens fed diets supplemented with S group in all periods (P
[ 4 ] - Effects of Electron-Beam Irradiation of the Diet on Microbial Population, Intestinal Morphology, Ileal Digestibility and Performance of Broilers
A total of 300 one-day old male broilers (Cobb 500) were randomly divided into four treatment groups. The groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kGy electron-beam irradiated diets. A total of 5 replicates were performed. The chemical composition of the diet was not affected by irradiation.Irradiation doses of 5 an...
[ 5 ] - A Comparison of the Effects of Dietary Ginger Powder and Avilamycin on Growth Performance and Intestinal Salmonella Count of Challenged Broiler Chickens
This study was conducted to evaluate the effect of ginger powder on the performance of Salmonella challenged broiler chicks and to compare its efficacy as growth promoter with an antibiotic, avilamycin. In a completely randomized design, 300 chicks were divided into six groups, five replicates with 10 birds per each replicate. The treatments included negative control (basal diet without ginger ...
[ 6 ] - Chemical Composition, Ruminal Dry Matter, Crude Protein andCell Wall Degradation Kinetics of Pasture Forages Dominant in the West Provinces of Iran
The objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of ten pasture forage species dominant in the west provinces of Iran. Duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. The chemical com...
[ 7 ] - Ruminal Degradation Kinetics of Wheat Straw Irradiated by High Doses of Electron Beam
This study was conducted to evaluate the effect of electron beam irradiation at doses of 250 and 500 kGy on the chemical composition and ruminal dry matter (DM) and neutral detergent fiber (NDF) degradability of wheat straw. Nylon bags of untreated or irradiated wheat straw were suspended in the rumen of three rams for up to 72 h, and resulting data were fitted to non-linear degradation model t...
[ 8 ] - تاثیر جایگزینی نخود پرتوتابی شده با پودر ماهی بر شاخصهای رشد، ترکیبات بدنی و قابلیت هضم ظاهری جیره بچه ماهی قزلآلای رنگین کمان (Oncorhynchus mykiss)
این تحقیق با هدف معرفی منبع پروتئینی جدید به جای پودر ماهی در جیره غذایی ماهی قزلآلای رنگین کمان (Oncorhynchusmykiss) انجام شده است. در این مطالعه دانه نخود کابلی معمولی (Cicer arietinum) و دانه نخود پرتوتابی شده جایگزین پروتئین پودر ماهی در جیره شد و اثرات آن بر شاخصهای رشد، تغذیهای، قابلیت هضمپذیری و ترکیبات بدنی بچه ماهی مورد بررسی قرار گرفت. این مطالعه در سالن تکثیر و پرورش پژوهشکده آرت...
[ 9 ] - اثرات پرتوتابی گاما، الکترون، مایکروویو و مادون قرمز بر هضمپذیری شکمبهای و برونتنی پروتئین کنجاله سویا
زمینه مطالعاتی: پرتوتابی منابع پروتئین گیاهی می تواند کیفیت آن را بهبود بخشد. هدف: این مطالعه بهمنظور مقایسه اثرات پرتوتابی گاما، الکترون، مایکروویو و مادون قرمز برتجزیهپذیری شکمبهای، قابلیت هضم برونتنی و بخشهای مختلف پروتئین کنجاله سویا انجام شد. روش کار: تجزیه پذیری، قابلیت هضم برونتنی و بخشهای مختلف پروتئین بهترتیب با تکنیک کیسه های نایلونی با استفاده از چهار رأس گوسفند نر بالغ دار...
[ 11 ] - ناپدید شدن شکمبهای پروتئین و اسیدهای آمینۀ کنجالۀ کانولای عملآوری نشده و عملآوری شده با پرتوهای گاما و الکترون
این پژوهش بهمنظور بررسی تأثیر دوزهای 25، 50 و 75 کیلوگری پرتوهای یونساز گاما و الکترون، بر ناپدیدشدن شکمبهای اسیدهای آمینه و زیرواحدهای پروتئین کنجالۀ کانولا انجام گرفت. آزمایش تجزیهپذیری با تکنیک کیسههای نایلونی اجرا شد. بدین منظور از سه رأس گاو نر تالشی مجهز به فیستولای شکمبهای استفاده شد. روند ناپدیدشدن شکمبهای زیرواحدهای پروتئین کنجالۀ کانولا، با تکنیک الکتروفورز ژل پلیآکریلامید در...
[ 12 ] - استفاده از پرتوتابی گاما برای حذف آلودگی باکتریایی آغوز گاو
In order to colostrum pasteurization and creating of dose-response curve for Escherichia coli and Staphylococcus aurous, the colostrum of cow was gamma irradiated at doses of 0, 0.5, 1 and 2 KGy. Chemical composition, true protein, electrophoretic pattern of proteins, lactose content, peroxide level and pH of colostrums samples before and after of irradiation were determinate. The obtained...
