Background:Valine and isoleucine are similar in chemical structure and their limitation in broiler chicken *** evaluate their limitation and interactive effects,multivariate assessment nutrition studies for the branched-chain amino acids(BcAA)are needed.A three level(−1,0,+1),three-factor Box-Behnken design study was conducted to assess dietary BcAA ratios to lysine of 65,75,and 85 for valine,58,66,and 74 for isoleucine,and 110,130,and 150 for leucine in male and female Lohman Indian River broilers from 22 to 35 d of ***:Live performance of male broilers was not affected by BcAA ***,male broilers fed increasing isoleucine had improved(P=0.07)carcass yield as leucine and valine were *** broilers had improved body weight gain(P=0.05)and feed conversion(P=0.003)when leucine and isoleucine were at their lowest levels,independent of valine,but increasing leucine impaired live performance and warranted concomitant increases in isoleucine to restore *** dietary isoleucine and valine in female broilers increased breast meat yield(P=0.05),but increasing leucine tended to diminish the ***:the female Lohman Indian River broiler is more sensitive to BcAA diet manipulation than ***,as dietary leucine is increased in female broilers,dietary isoleucine increases were needed to offset the negative *** increases in dietary valine and isoleucine improved breast meat yield in female broilers,but only when birds were fed the lowest dietary leucine.

the aim of the present work is fabrication of dual cross linked sodium alginate(SA)/montmorillonite(mmt) microbeads as a potential drug vehicle for extended release of curcumin(cUR). the microbeads were prepared using in situ ion-exchange followed by simple ionotropic gelation technique. the developed beads were characterized by Fourier transform infrared spectroscopy(FtIR), differential scanning calorimetry(DSc), thermogravimetric analysis(tGA), X-ray diffraction(X-RD) and scanning electron microscopy(SEm). the effect of mmt on encapsulation efficiency of cUR and intercalation kinetics was investigated. Dynamic swelling study and in vitro release study were investigated in simulated intestinal fluid(pH 7.4) and simulated gastric fluid(pH 1.2) at 37 ℃. Results suggested that both the swelling and in vitro release studies were influenced by the pH of test media, which might be suitable for intestinal drug delivery. the release mechanism was analyzed by fitting the release data into KorsmeyerPeppas equation.
