Influence of plant protein, lysine and methionine on the performance of growing Japanese quail
Abstract: Eight hundred and forty one-day-old Japanese quail chicks were distributed randomly into seven groups and each one in five replicates (24 chicks/replicate). The first group (control, T 1) received a diet contain 24% crude protein (CP), 2900 Kcal. ME/kg diet, lysine 1.3% and methionine 05% during the whole experimental period from hatch up to 42 days of age.
Minerals and vitamins were adequately supplied to cover the requirements. The other six groups (T 2 - T 7) received a diet contain lower CP 22% and similar energy Two levels of lysine 1.3% and 1.6% and every level had methionine 0.5%, 0.6% and 0.7% at the same period. Results obtained could be summarized as follow; quail chicks fed a diet with 22% CP, 1.6% lysine and 0.7% methionine during whole experimental period are significantly (P<0.05) heavier in body weight gain (BWG), improved feed conversion (Fe), increased dressing percentage and reduced mortality than other treatments. No significant difference was detected between quail chicks fed either 24% or 22% CP on BWG, feed intake and Fe. Quails fed diet contained 1.6% lysine had significantly (P<0.05) increased BWG and improved FC ratio compared with birds fed diets contained 1.3% lysine. The level of 0.7% methionine showed significant (P<0.05) increase in BWG and improved FC ratio than other levels. Quail chicks fed diets containing 22% CP, 1.6% lysine and 0.7% methionine significantly (P<0.05) gave the highest dressing percent than those for TI, T2 and T3 groups. While it was similar to those fed diets of
T 4, T5 and T6. No significant (P<0.05) differences in giblets data were found for all treatment. Serum total protein, albumin, globulin and alkaline phosphatase activity revealed that no adverse effect due to feeding quail chicks different levels of protein, lysine and methionine It could be concluded that the ideal diet to maximize the efficiency performance of quail chicks contained 22% CP, 2900 kcal ME/kg diet, 1.6% lysine and 0.7% methionine.
