An experiment was conducted to study the effect in ovo injection of vitamins on the embryonic and post-hatch growth performance. Fertile eggs (n=350) were weighed, distributed in to 7 groups and set in force-draft incubator. On 14 th ED five groups were injected with 100 IU Vitamin-A, 0.5 IU Vitamin-E, 50 mg Vitamin-C, 100 μg Vitamin B1 and 100 μg Vitamin B6 dissolved in 0.5 ml of sterile water...

Fifty white leghorn chicken (Gallus domesticus) eggs per group were injected with 0.1, 1.0, 10.0, or 20.0 microg perfluorooctane sulfonate (PFOS)/g egg before incubation to investigate the effects of PFOS on the developing embryo. Hatchlings were weighed, examined for gross developmental abnormalities, and transferred to a battery brooder, where they were raised for 7 d. Chicks were then weighe...

This research was conducted in the field of poultry Department Animal Production Techniques for period 6/9/2011 until 23/11/2011 order to study effect adding alcoholic extract ginger, propolis and cinnamon (cinnamon) reducing cholesterol yolk white quail eggs, which used 280 one-day-old chicks were divided into seven groups with two replicates each group. The homogeneous weights placed 13 kanna...

This study evaluated the effects of elevated incubation temperature on posthatch nutrient transporter gene expression, integrity of the intestinal epithelium, organ development, and performance in Ross 308 broiler chickens. Ross × Ross 308 fertile eggs (n = 900) were incubated at different eggshell temperatures during development. From embryonic day (ED) 1 to ED12, all eggs were incubated at 37...

The aim of this study was to investigate whether a L-carnitine, choline, artichoke leaf extract and sorbitol combination (Hepabial Carnitine ® ) supplied by drinking water would influence broiler performance under stress induced by high stocking density (18 chicks per square meter). A total of 270 1-dayold male broiler chicks (Avian Farm) were randomly distributed into 2 groups (Hepabial Carnit...

With the technical assistance of P. Johnson Hypertension induced by adding sodium chloride to the diet (0.9 per cent) or drinking water (8 per cent) of chicks on plain mash did not intensify spontaneous atherosclerosis or lead to atherosclerotic lesions of the induced type. H YPERTENSION in man is typically associated with increased incidence and severity of atherosclerosis. Conversely, many pe...

The major histocompatibility (B) complex influence on resistance, susceptibility, and immunity to Eimeria tenella was examined in UCD B complex congenic chicken lines. In Experiment 1, 6-wk-old chicks from 12 UCD congenic lines were weighed and assigned to either challenge or control groups. The challenge group received a dose of 10,000 E. tenella oocysts. Response to challenge was evaluated by...

an experiment was conducted to evaluate the effect of early feed restriction on performance and serum thyroxin concentration of broiler chicks. the experiment was designed in a 2×2 factorial with 5 replicates of floor pens with 12 male or female chicks in each. 240 male and/or female day-old chicks of a commercial strain (hybrow) were wing banded, weighed and randomly allocated to two treatment...
