Abstract/ Executive Summary:

The study was conducted to determine the effects of dietary supplementation of a commercial probiotic (Protexin) on daily feed consumption, egg yield, egg weight, feed conversion, external and internal qualities of egg and livability in layer hens. To achieve the objectives a total of 96, 42 week- old layers arranged in four dietary treatment groups including control, containing 8 birds/ replication supplemented with 0, 0.5, 1.0 and 1.5% probiotic for a period of 16 weeks. The study reveals that the hen day egg production, feed conversion, egg weight and mass, egg shell weight, egg thickness and egg breaking strength increased linearly with the use of dietary protexin. However, livability and internal egg quality were not altered with the use of dietary protexin. Present study concluded that dietary supplementation of pro biotic promote the laying performance and most of the external quality characteristics of eggs. In conclusion, it is recommended that dietary supplementation of probiotic at the rate of 1.5 gm per kg feed in the layer ration may be economically potential.

Keywords: Supplementation, Probiotic, Performance, Layer, Protexin

Location: BAU, Poultry Farm, Mymensingh

Start Date: 01-01-2002

End Date: 31-12-2002

Program Area: Animal Health and Management

Commodity: Poultry

Objectives:

1 To evaluate egg production, egg quality and livability of layers fed protexin as a probiotic,

2 To find out the suitable dose of protexin for maximum production,

3 To study the profitability of using protexin in layer diet.

Methodology:

The research was conducted for the period of 16 weeks at Bangladesh Agricultural University (BAU) Poultry Farm (2002), Mymensingh, to evaluate the efficiency of a probiotic (Protexin) for laying birds. An open sided house was used for rearing experimental birds and proper hygienic measures were taken in every step of management. Ninety six (96) commercial layers (Shavar 579) were selected randomly rearing in same farm at an age of 42 weeks and placed group wise in the experimental cages. Required feed ingredients for making diets for experimental birds were supplied by the poultry farm of BAU. Crushed maize, wheat, till oil cake and oyster shells were mixed by weight according as per requirement of each dietary treatment. The collected data on laying performance and egg quality characteristics were analyzed using MSTAT computer package programme in a Completely Randomized Design. Duncan's Multiple Range Test (DMRT) was used to compare of mean values for to identify significant differences.

Achievement/Findings:

i) The dietary supplementation of probiotic may promote laying performance and most of the external quality characteristics of eggs. ii) Inclusion of probiotic at the level of 1.5 gm per kg of feed may be recommended to maximize layer performance and may economic. In Bangladesh very little work has been reported regarding the use of probiotic in poultry diet. But in abroad various significant works have been performed on meat and egg production. Therefore more research works in Bangladesh condition need to be conducted by using probiotic in poultry diet particularly when the climate becomes too hot and humid.
