چکیده

the present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to newcastle disease virus vaccination and bone mineralization. the experiment was conducted using 300 ross 308 male broilers. one-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 20 birds per pen. chickens were fed one of three dietary treatments with varying concentrations of valine; the first diet was adequate in valine (0% valine), the second and third diets had an excess in valine (0.08% and 0.16% synthetic valine in diet) because valine was added in place of inert filler. the results showed that supplemental dietary valine did not alter either feed intake, body weight gain or feed conversion ratio. hemagglutination inhibitiontitre was significantly increased when valine was added to the diet (p

Effects of low phytic acid corn on phosphorus utilization, performance, and bone mineralization in broiler chicks.

In vivo and in vitro experiments were conducted to determine whether P in a low-phytate corn (LPC) containing the lpa 1-1 allele is more available than P in a near-isogenic wild-type corn hybrid (NC). The LPC was analyzed to contain 0.18% nonphytate P and 0.26% total P (TP), whereas NC contained 0.05% nonphytate P and 0.25% TP. For these studies, nonphytate P was considered to be available P (A...
