the study was conducted to determine the effects of turkey (meleagris gallopavo)egg weight on certain egg traits and hatching performance. a total of 178 turkey eggs comprising of three different egg weight groups below 60 g (g i), 61 to 69 g (g ii) and above 70 g (g iii) were used for this study. average egg weight (g), egg length (cm), egg breadth (cm) and egg volume (cm3) values increased wi...
ارزیابی اثر داروی انروفلوکساسین بر فرایند آنژیوژنز با استفاده از مدل غشاء کوریوآلانتوئیک جنین ماکیان
چکیده به منظور ارزیابی تأثیر داروی انروفلوکساسین بر روی فرایند آنژیوژنز، تخم مرغ های نژاد راس (میانگین وزن 4±55 گرم) انکوبه شدند. در روز چهارم انکوباسیون، یک پنجره ی 5/1×1 سانتی متری در محور طولی ایجاد شد و تخم مرغ ها به دو گروه تقسیم شدند (7 تخم مرغ در هر گروه). در روز 7، انروفلوکساسین (mg/ky egg weight 10) در گروه درمان، روی پرده کوریوآلانتوئیک تلقیح شد و گروه کنترل pbs دریافت کردند. سه روز ...
Different types (light to heavy) of laying hens are used in practice. There are questions about the optimum level of balanced protein (BP) supply in feed for different types of hens. Therefore, a broad range of amino acids intake levels [550 to 800 mg of true fecal digestible (TFD) Lys/hen per d] was tested on heavy (Lohmann Brown Classic) and light (Lohmann LSL Classic) laying hens from 24 to ...
Environmental influences on egg and clutch sizes in lenticand lotic-breeding salamanders. Recent research indicates that social and environmental factors influence egg and clutch sizes in amphibians. However, most of this work is based on the reproductively diverse order Anura (frogs and toads), whereas less research has been conducted on Caudata (salamanders) and Gymnophiona (caecilians). Rese...
This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...
This experiment was conducted to investigate the effects of egg yolk and soybean oil as early feeding to broiler chicks on growth performance and intestinal morphology. A number of 525 chicks (Ross 308) were allocated to 7 treatments with 5 replicates and 15 birds in each replicate in a completely randomized design. Treatments were: control group (without early feeding), and feeding of 0.4 and ...
The aim of this study was to evaluate the effects of dietary vitamin E on reproductive and productive parameters in Japanese quails. A total number of 240 female and 80 male Japanese quail were divided into five treatments with four replications in a completely randomized design. Experimental diets were zero control, 30, 60, 120 and 240 mg kg-1 of vitamin E. Fertility and total hatch...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
BACKGROUND Dietary induction of antisecretory factor (AF) can reduce diarrhoea in patients with inflammatory bowel disease. Patients with neuroendocrine tumours may suffer from diarrhoea with a prominent secretory component. We studied if AF-therapy could affect this type of diarrhoea. METHODS Six patients with the midgut carcinoid syndrome and two with metastasizing medullary thyroid carcino...
BACKGROUND Approximately 1/3 of individuals have a high plasma response to dietary cholesterol (hyper-responders). Although increases in both LDL and HDL cholesterol have been observed, limited data exist regarding effects of egg consumption on lipoprotein subclasses and circulating carotenoids. METHODS 29 postmenopausal women (50-68 y) and 13 men (60-80 y) were assigned to either 3 eggs (EGG...
