SUMMARY
The Effects of Various Dietary Levels of Cottonseed Meal Supplemented With Fiili Meals On the Eight Week Body Weight and the Feed Efficiency of Broilers
An experiment was conducted to
determine the maximum practical levels
ofcottonseed meal supplemented
with various levels of fish meals in the
rations of broilers in eight-week period.
Eight-week body weight and the
feed efficiency were the criteria used
to measure the response. '
The experiment was conducted
with Hubbard broiler chicks, day-old
to eight weeks of age. Chicks were ma
intained in electrically heated battery
brooders raised wire floors throughout
the experimental periods. The experimental
diets and water were supplied
Ad libi(um. Completely randomized
block design of dietary treatrnents
involving six levels (O %, 5 %, 10
%. 20 %, 30 %, and 40 %) of cottonseed meal and and six levels (3 %,
4 %, 5 %, 6,5 %, 7 %and 10 %) of
fish meals was used in the experiment.
One group of sixteen male and one
group of sixteen female chicks we.re
assigned to eaeh of the six dietary
treatments.
Data pertaining to eight-week
body weight and feed efficiency were
subjected to analysis of varİance (Steel
and Torrie, 1960).
Data obtained from this experiment
indicated that:
ı. There wer~ no significant differences
among dietary treatments relative
to eight-week body weight and
feed efficieney. '
2. The lowest body weights were
obtained from the ehicks receiving forty
pereent of cottonseed meal in their
rations.
3.. The cottonseed leve1s used in
this experiment did not influenee survival
of ehieks İn eight-week period.
