PREDICTION OF SOME GROWTH, CARCASS AND SELENIUM STATUS TRAITS THROUGH DIATARY ORGANIC SELENIUM CONCENTRATIONS IN JAPANESE QUAIL.
Since there is a lack of data about prediction and correlation of performance, selenium status and antioxidant properties through selenium supplementation in diets, the objective of this research was to examine the significance of correlation and regression effects of four (0.0, 0.1, 0.3 and 0.5mg/kg) levels of three sources of organic selenium tested to predict performance traits, carcass characteristics, selenium status (in diets, whole blood, excreta, feather, liver, breast and thigh muscles), thyroid hormones, glutathione peroxidase (GSH-Px) and lipid peroxidase (determined as TBA) in Japanese quail. The main results are summarized as follows: 1. 1. It is easy to predict Se concentration in the excreta, feather, liver, breast and thigh meat and whole blood at 35 days of age in Japanese quail through positively significant correlation (P≤0.01 r: 0.289 to0.970) and linear regression equations with R2 ranged from 4.123 to 94.006%, however, the increase in Se Diet resulted in a decrease in Se Whole blood as follows: Se Whole blood= 0.187-0.037Se Diet (R2 :8.951, P≤0.01). 2. Correlation and regression analysis of the data failed to indicate any significant relationship between Availa' Se Diet and performance or carcass traits. However, thigh weight decreased as dietary Availa inclusion increased (r:-0.387, P ≤0.05) as follows: Thigh weight= 40.227-10.400 Se Diet (R2:15.010%, P≤0.042). 3. Adding Bioseleno organic Se into the basal diet significantly decreased either the EEf and REEf as follows: EEf = 4.870-3.503X(R2: 30.237%, P≤0.000) and REEf =1.127-0.811X (R2 : 30.237%, P≤0.000). Similarly, diets supplemented with graded levels of Selvail resulted in decreases in each of BW35, Gain7-35, EEf and REEf. 4. Mortality % statistically decreased (P>0.05) as Se Diet increased as Availa or Bioseleno whereas, mortality increased in the groups fed graded levels of Selvail
