The Influence Of Dietary Energy, Protein And Copper Levels On The Sulphur Amino Acid Requirements Of Broiler Chickens
Three experiments were conducted with male broiler chicks to determine the influence of dietary metabolisable energy ( ME ) , crude protein (CP) and copper (Cu ) levels on the total sulphur amino acid (TSAA) requirement of broilers both during the starter ( 0-3 wk) and t he grower periods ( 4-6...

| description | Three experiments were conducted with male broiler chicks
to determine the influence of dietary metabolisable energy
( ME ) , crude protein (CP) and copper (Cu ) levels on the total
sulphur amino acid (TSAA) requirement of broilers both during
the starter ( 0-3 wk) and t he grower periods ( 4-6 wk) reared in
the tropics . In all the experiments the parameters used to
evaluate the TSAA requirements are body weight gain , feed : gain
ratio and carcass composition.
In the first experiment , two factorial arrangements of three ME levels ( 3000 , 3200 and 3400 kcal /kg ) x four level sof
TSAA ( 0 . 73 , 0 . 83 , 0 . 93 and 1. 03% ) and the same three ME levels
( 3000 , 3200 and 3400 kcal /kg ) x four levels of TSAA ( 0 . 65 ,
0.72 ,0.79 and 0.86% ) were used for t he starter and the grower periods,respectively . The results showed significant
differences ( p< . 05 ) in body weight gain and feed : gain ratio of
the broilers within creasing dietary TSAA levels both in
starter and grower periods. There were no significant
interaction ( p< . 05 ) between dietary ME and TSAA levels for
the performance , with the exception for feed in take of starter
broilers . It indicated that for the starter period , a TSAA of
0 . 93% produced the best performance regardless of energy levels
while for the grower period the requirement of TSAA at both
0 . 79 and 0 . 86% were suggested . The results further showed
that dietary energy levels had no effect on the TS AA
requirement of the broilers. |
