Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 5
Abstract
This experiment was conducted to investigate the effects of different levels of canola oil with vitamin E on performance and carcass traits of broilers. This study was carried out as 3×2 factorial experiment with 3 levels of canola oil (control, 2.00 and 4.00 percent) and 2 levels of vitamin E (0 and 150 mg/kg) in 6 treatments, 3 replicates and 14 birds in each replicate in a completely randomized design. In this experiment 252 day old broiler chicks (Ross 308 strain) were used for 42 days. Inclusion canola oil until 2% did not have any significant effects on performance of broilers, whereas adding 4% of canola oil significantly decreased their carcass percentage (P<0.05). Using 150 mg/kg of vitamin E significantly affect the performance and carcass traits of broilers. The lowest amounts of daily weight gain (39.38g), daily feed intake (85.91g) and the highest ratio of feed conversion (2.19), the lowest carcass (68.04%) and abdominal fat (2.76%) and the highest liver (4.12%) percentages were resulted by inclusion 150 mg/kg vitamin E.

Improved Based DCT Correlation Watermarking
In this paper, an improved based DCT correlation watermarking has been proposed. In the proposed scheme the watermark is scrambled and reshaped to a sequence; then two separate PN sequences are used to encode “1” and “...
