LAYING PERFORMANCE AND EGG QUALITY OF QUAILS

SUPPLEMENTED WITH NaHCO3 DURING LATE

LAYING PERIOD

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?

• 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)

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.

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.

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)

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)

• 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)

METHODOLOGY

• MaterialJapanese 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.

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

• 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

• StatisticsThis 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.
