| The objective of this study was to evaluate the influence of vitamin C (VC), vitamin E (VE), and two selenium sources on the performance, yield, and composition of Nile tilapia fillet. The experiment was conducted in a completely randomized design consisting of six treatments with the addition of 100, 200, and 400 mg kg-1 VC and VE and 0.1, 0.2, and 0.4 of two sources of selenium. Each treatment had five replicates of 30 fish each. The diet with 200 mg kg-1 VC and VE + 0.2 mg.k-1 organic selenium resulted in weight gain, length gain, and feed conversion ratio similar to that of the treatment with 400 mg kg-1 VC and VE + 0.4 mg kg-1 organic or inorganic selenium. The addition of organic selenium to the diet improved the weight gain and feed conversion ratio... |

| The objective of this study was to estimate the requirements for maintenance and gain of crude protein in Japanese and European quails aged 16-36 days. To determine the maintenance requirements, one experiment was conducted in a completely randomized design with four decreasing feeding levels (100, 75, 50 and 25%) and four replicates per treatment. The method of comparative slaughter was used, through a feeding assay. A total of 352 quails from each strain were housed by supply level in 16 pens measuring 1.0 × 1.5 m, totaling 22 birds per cage under ambient temperature conditions (26±0.5 ºC). To estimate the requirement gains, one experiment was conducted with five groups of quails fed ad libitum and housed under controlled temperature of 18 ºC. All... |
