Abstract

This experiment was conducted to study effect of using fennel
seeds in growing Japanese quail (Coturnix coturnix japonica) diets
varying in their protein content with or without enzymes
supplementation. At 10 days of age birds were divided into twelve
treatments (60 birds each), each treatment contained 3 replicates of
20 birds each. The experimental treatments were as follows:-
1 Chicks were fed the control diet containing 24% crude protein (CP), diet 1.
2 Chicks were fed diet 1+ 0.1% kemzyme dry (KD).
3 Chicks were fed diet 1 + 1% fennel seeds.
4 Chicks were fed diet 1 + 1% fennel seeds + 0.1% KD.
5 Chicks were fed diet containing 21%CP.
6 Chicks were fed diet containing 21%CP + 0.1% KD.
7 Chicks were fed diet containing 21%CP + 1% fennel seeds.
8 Chicks were fed diet containing 21%CP +1% fennel seeds+ 0.1% KD.
9 Chicks were fed diet containing 18%CP .
10 Chicks were fed diet containing 18%CP + 0.1% KD.
11 Chicks were fed diet containing 18%CP + 1% fennel seeds.
12 Chicks were fed diet containing 18%CP +1% fennel seeds+0.1% KD.
Results obtained could be summarized in the following:
1- Quail fed the control + fennel + KD had higher values of live body
weight (LBW) at 31 and 38 days of age, however, those fed 18 %
CP + fennel had lower LBW at the same ages.
2- Quails fed diet control + fennel + KD had the heaviest live body
weight gain (LBWG) during the period from10 to 38 days of age,
whereas quails fed diet 18% CP + fennel + KD had the lower
LBWG during the previous period.
3- Quails fed 18% CP+ fennel had lower feed intake (FI) during the
period from 10 to 38 days of age. However, quails fed control diet
had the highest FI value during the same period.
4- Quails fed diet containing 21% CP+KD had better feed conversion
value during the period from 10 to 38 days.
5- Quails fed diet containing 18 % CP + fennel had the better crude
protein conversion (CPC) value during the period from 10 to 38
days of age. Quails fed control diet + fennel had the worst CPC
value during the period from 10 to 38 days of age.
6- Quails fed control diet+ fennel +KD had higher performance index
value during the period from 10 to 38 days.
7- Insignificant effects on slaughter parameters of Japanese quails were
found. Females had higher carcass weight before evisceration %,
liver % and total giblets % than males. Males had higher heart %,
abdominal fat %, carcass weight after evisceration %, whole
front%, whole rear %, rear meat % and dressing % than female.
8- Quails fed diet containing 21 % CP + KD had the lower serum
cholesterol while quails fed diet containing 18 %CP+ fennel +KD
had the higher contents of serum glucose.
9- Higher moisture and protein (the lowest fat%) values were observed
for quails fed diet containing 21% CP while those fed 21% CP+
fennel had the highest fat % (and consequently the lowest moisture
and protein%).
10- The percentage of mortality was 3.33% in quails fed diet
containing 18% CP+ KD. However quails fed control diet, control
diet+ KD, control diet+ KD +fennel, 21% CP, 21% CP+ KD and
18% CP the percentage of mortality was 1.67%. No mortality was
found in quails fed other experimental diets.
11- Quails fed D9 (containing 18% CP) gave the best economical and
relative efficiency values, followed by quails fed D11 (containing
18% CP+1% fennel seeds) when compared with the other
treatments or the control.
It can be concluded that
1- The supplementation of growing Japanese quail diet with 1.0%
fennel improved productive performance.
2- Starter diets for quail should contain protein content of 24% this
may be reduced to 21% at few weeks later.
