This experiment was conducted to investigate the effects of dietary essential oil combination (sage, thyme, and mentha extracts) (EOC) and vitamin E (Vit E) supplementation on laying hens’ performance, egg quality, yolk Thiobarbituric Acid Reactive Substance (TBARS) values and Escherichia coli (E. coli)and Coli form bacterium counts in excreta. One-hundred and twenty Lohmann white layers (36 we...

optimum concentration of vitamin c and hardness at giant freshwater prawn brood-stock tank water has great important on their reproductive quality in recirculation system. the main objective of the present study is investigation on effects of different concentrations of these factors on reproductive parameters of the giant freshwater prawn female brood-stock. for this purpose, at the first expe...

In a 2  3  2 factorial arrangement, 144, fifty–four-week-old laying hens, in 12 treatments with 12 replicates for each treatment, received one of 12 diets based on maize or wheat containing three levels of dried tomato pomace (DTP: 0, 50 and 100 g/kg) as a substitute for wheat bran, and two levels of pigment (0 and 900 mg/kg), for 9 weeks. Weight gain (WG), egg production (EP), egg weight (EW...

This paper investigates whether the advanced Korean learners of standard Chinese produce Chinese with specific voice quality, and which voice quality parameters have significant difference. The study includes comparative analysis between the Korean and Chinese vowel /a/ for Korean speakers. It can be made certain by measuring voice quality parameters by means of EGG (electroglottalgraphy). The ...

The development of an assay for the quantification of chicken immunoglobulin (IgY) and data evaluation is being demonstrated. An enzyme immunoassay was established to perform the quality control of IgY purifications from the egg yolk and to control IgY producing cells in vitro. Each step of the test procedure and possible alternatives were described. The assay was characterized by special test ...

This paper describes a prototype system for the objective assessment of voice quality in patients recovering from various stages of laryngeal cancer. A large database of male subjects steadily phonating the vowel /i/ was used in the study, and the quality of their voices was independently assessed by a speech and language therapist (SALT) according to their seven-point ranking of subjective voi...
