2. LAYING PERFORMANCE AND
EGG QUALITY OF QUAILS
SUPPLEMENTED WITH
NaHCO3 DURING LATE
LAYING PERIOD

3. INTRODUCTION
Malaysia is a hot and humid country, thus
livestock have a higher chance of suffering
from heat stress. By adding sodium
bicarbonate in the drinking water, it can
reduce the heat stress. Thus, there is no
obvious harmful consequences’ by conducting
this experiment. Why use quails?

4. • From the technical and economic viewpoints, quail
rearing is attractive due to their rapid growth and early
onset of lay, high reproduction rates, and low feed
intake
(Murakami and Ariki, 1998; Albino & Barreto, 2003)
• Egg production rate decreases and egg weight
increases as age advances.
(Al Bustany and Elwinger, 1987; Summers and Leeson, 1983)
• Egg quality and composition also change in accordance
with level of production and age of layers. As age
advances, proportion of yolk increases, whereas
proportion of albumen and shell thickness decrease.
(Akbar et al., 1983: Fletcher et al., 1983)

5. OBJECTIVES
• To evaluate the laying performance and egg
quality of quails supplemented with sodium
bicarbonate (NaHCO3).
• To determine if there is a significant
difference between groups of quails
supplemented with sodium bicarbonate and
quails that aren’t supplemented with sodium
bicarbonate in the late laying period.

6. HYPOTHESIS
Quails supplemented with NaHCO3 has a better
egg quality and improved laying performance
compared to quail that not supplemented
with NaHCO3 in the late laying period.

7. LITERATURE REVIEW
• Japanese Quail (Coturnix Japonica)
→ Originates from Eastern Asia
→ Domestication
→ The colour of the Japanese quail
→ Adult quail height and weight
→ The biggest commercial revolution of the
quail
→ Quail can be kept in …
(Murakami at el., 2006)

8. LITERATURE REVIEW
• Laying Quails
→ Common term
→ Female Japanese may start laying eggs
(Murakami at el., 2007)
• Dietary Supplement
→ To provide nutrients
→ Supplements generally includes
(Balnave and Muheereza, 1997)

9. • Sodium Bicarbonate
• the chemical compound
(Balnave and Muheereza, 1997)
• Egg Shell
A Coturnix egg weighs
(Murakami and Ariki, 1998)
The basic shell color
(Murakami at el., 2008)
• Egg Shell Quality
• The aesthetic quality of the egg shell
(Balnave and Muheereza, 1997)

10. METHODOLOGY
• Material
Japanese Quail (Coturnix Japonica) aged 120
days, sodium bicarbonate
• Location: Ladang 2
• Diets, birds and their management
Area of 6.3cm of feeder/bird.
3 groups of hens.
Will be fed with commercialized feed.

11. Group Of Quails (Hens) Sodium Bicarbonate(%)
In Drinking Water
Group A Treatment I - 0.0%
Group B Treatment II- 0.2%
Group C Treatment IV- 0.4%
Cont.
*Each group will have 10 quails. Each
treatment will be replicated three times

12. • Data Collection and Analytical Procedure
→ Feed conversion ratio will be expressed as
kilogram of feed intake per kilogram of egg
production.
→ Feed intake and egg production will be
recorded daily.
→ A sample of 10 eggs :randomly collected from
each experimental group every 7 days interval to
asses egg quality parameter (egg weight, specific
gravity, shape index, shell stiffness, shell
thickness, yolk colour, albumin index, yolk index).
Before determination of egg weight, a sample of
eggs collected weekly will be stored for 24 hours
at room temperature

13. • Statistics
This experiment will be arranged in a
complete randomized block design. One way
ANOVA will be conducted using the Mixed
Procedure (SAS, 1998) as repeated measures
with time being subplot.
