this experiment was conducted to evaluate the effects of vitamin c on laying hens performance, egg characteristics and some blood parameters under normal rearing condition. one hundred and ninety two 24 - weeks - old laying hens diet were used in a completely randomized design with 4 treatments (0, 250, 500 and 750 mg vitamin c/kg diet) and 4 replicates for 105 days. although feed consumption, ...

OBJECTIVE There is little evidence on the role of topical budesonide in reducing the frequency of adenoidectomy, although it was reported that topical budesonide can effectively ameliorate the symptoms of adenoid hypertrophy (AH). This study was aimed to investigate the possibility and safety of alternatives to adenoidectomy with a 12-week treatment with nasal budesonide. MATERIALS AND METHOD...

The fabrication of self-assembled Au droplets is successfully demonstrated on various GaAs (n11)B, where n is 2, 4, 5, 7, 8, and 9, by the systematic variation of the Au deposition amount (DA) from 2 to 12 nm with subsequent annealing at 550°C. Under an identical growth condition, the self-assembled Au droplets of mini to supersizes are successfully synthesized via the Volmer-Weber growth mode....

OBJECTIVE A study was conducted to test six threonine (Thr) levels (0.39%, 0.44%, 0.49%, 0.54%, 0.59%, and 0.64%) to estimate the optimal dietary Thr requirements for Longyan laying ducks from 17 to 45 wk of age. METHODS Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary treatments, where each treatment comprised six replicate pens with 25 ducks per pen. RESULTS...

A quantitative analysis of NMR proton relaxation in hen egg albumen and yolk is undertaken to research the causes of quality loss during the first few days of storage and to access the feasibility of an on-line NMR sensor of internal egg quality. It is shown that the change in the transverse relaxation in thick egg albumen mainly results from an increase in proton exchange rate resulting from a...

Salmonella spp. present in pasteurized egg albumen are often difficult to recover by direct plating because of thermal injury and the presence of innate iron binding and other antimicrobials in egg white. The literature has reported a multiplicity of selective and nonselective media used to recover heat-injured Salmonella, to measure the proportion of injured cells, or both. This study compared...

This study aimed to evaluate the internal and microbiological quality of eggs submitted different types shell treatments. One hundred forty-four fresh red were distributed in a scheme 4 treatments (no washing; washing immersion chlorine; peracetic acid; spraying propolis extract) x 5 storage periods (7, 14, 21, 28, 35 days), stored at 25°C, each period 6 per treatment analyzed. The parameters a...
