Abstract
An experiment was conducted to study the effect of feeding recommended (23%, Diet1) or high
(25%, super starter, Diet2) crude protein in starter diets on productive performance, carcass
characteristics and economical efficiency of Hubbard broiler chickens. A total of 225, day old
Hubbard broiler male chicks were randomly distributed into 5 treatments at (1-35) days of age, each with
three replicates of 15 birds each. The five treatments were: T1) Control group, chicks fed (Diet1) ad-libitum
the other treatments from T2 till T5, chicks were fed (Diet2)at different quantities being 125g, 250g, 375g and
500g/chick, respectively followed by (Diet1) to the end of starter period (14 days of age). During grower and
finisher periods, all chicks were fed recommended diets at these phases. At the end of experiment at 35 days
of age, 4 broilers chicken per treatment were slaughtered and evaluated for carcass traits. The results indicate
that: Body weight, body weight gain and feed intake were linearly increased, whereas feed conversion ratio
decreased as super starter diet increased, during overall period (1-35 days of age). The best values of body
weight gain, feed conversion ratio, protein and energy conversion ratio were observed for chickens fed 500g
super starter diet compared with other dietary treatments. In most cases differences between treatments were
significant (P≤0.01). Carcass characteristics of chicks fed super starter diet, added at different levels had no
effects on carcass characteristics. The best economical efficiency value were demonstrated when broiler
chickens fed (500g Diet2/chick) super starter diet and the values was 33.09% more when compared to that of
chicks fed control diets. In conclusion, feeding broiler chickens super starter diet at level of (500g/chick)
support and enhance productive performance and economical efficiency.
