Abstract/ Executive Summary:

An experiment was conducted to investigate the effect of feed supplementation on chemical composition of Jinding duck’s egg. A total of 180 physically sound eggs were randomly collected in each time at 50% and 75% level of egg production of the ducks. Significant difference was observed for dry matter content of egg albumen of ducks fed on different diets at 50% level of egg production (P<0.01) but no significant difference was recorded for dry matter content of egg yolk at 50% level of egg production (P>0.05). The CP contents of egg albumen and egg yolk differed significantly (P<0.01) at 50% level of egg production but the difference was not significant (P>0.05) for CP content of egg yolk at 75% level of production. There were significant differences (P<0.01) on EE and TA contents of egg albumen and egg yolk at all levels of production. The results of the study demonstrated that the dry matter, as well as crude protein, ether extract and total ash content of eggs on dietary treatment T₁ (Scavenging + standard ration ) was highest compared to the eggs on other treatment groups (T₀, T₂, T₃, T₄ and T₅).

Commodity: Duck

Objectives:

To study the effect of feed supplementation on chemical composition of eggs laid by Jinding ducks under scavenging system of rearing in coastal areas Bangladesh.

Methodology:

The experiment was conducted for a period between October, 2003 and August, 2004 in three villages of Ramgati upazilla viz., Purba Kolakupa, Char Kolakupa and Char Poragacha in the district of Lakshmipur. A total of one hundred forty four, 4-month old Jinding ducks were reared up to the age of 12 months. Experimental design and treatments The ducks were randomly assigned to 6 treatment groups having 3 replicates in each treatment. Each replicate consisted of 8 ducks. All the birds wee supplied mash feed in addition to allowing them for scavenging. Feeding and management A standard ration was prepared using corn, rice polish , wheat bran, meat meal, soybean meal, mustard oil cake, common salt, vitamin-mineral premix, oyster shell and soybean oil, well mixed and supplied to the ducks belonged to treatment T₁ group. Similar quantity of rice polish, broken rice, a mixture of rice polish and broken rice (1:1) and rice polish, broken rice and wheat bran (5:3:2) wee supplied to the ducks of T₂, T₃, T₄ and T₅ treatments, respectively. The amount of supplemental feeds were divided into two equal halves and were given twice daily (7.30 A.M. and at 5.30 P.M.). All ducks were vaccinated against Duck Plague and Duck Cholera. The experimental birds were allowed to scavenge 5.00 P.M.). Feeds were supplied in the bowls in the form of wet mash and the bowls were cleaned properly before each feeding time. Sufficient clean drinking water was also supplied in bowls in each time of feeding. Proper care and management practices were followed by the researcher and farmers throughout the experimental period. Collection of egg sample The freshly laid eggs of Jinding ducks were collected from the farmers. The eggs were collected in two times, once at 50% and other at 75% level of egg production of Jinding ducks. Five numbers of eggs were taken from each treatment at each level of production. Each time of collection, all the eggs were identified properly with individual serial number. For this purpose, a total number of 180 eggs were collected randomly from 6 treatments groups at 50% and 75% level of egg production. Chemical analysis Dry matter (DM), crude protein (CP), ether extract (EE) and total ash (TA) content of eggs were done following the principles of AOAC (2004). Statistical analysis Data were analyzed statistically using analysis of variance technique for a completely randomized design and significant differences among the treatment means were identified by Duncan’s Multiple Range Test (Steel and Torrie, 1980).freely in the agricultural fields, ponds and ditches near to farmer’s house for 9 hours.

Achievement/Findings:

The results indicated that the dry matter, crude protein, ether extract and total ash contents of egg albumen and egg yolk are higher in 75% level of egg production over 50% level of egg production. The results of the study also demonstrated that the dry mater, as well as crude protein, ether extract and total ash content of egg albumen and egg yolk on dietary treatment T₁ (Scavenging + standard ration ) was highest compared to the eggs of other treatment (T₀, T₂, T₃, T₄ and T₅) groups.
