Abstract/ Executive Summary:

A total of 63 day-old straight run Layer chicks up to 45 weeks of age on 3 isonitrogenous and isoenergetic diets D₁ (6% PC+ 0% SWP), D₂ (0% PC+ 6% SWP), and D₃ (0% PC+ 8% SWP) were fed to observe the effect of dietary SWP on growth and egg production performance. This study revealed that profitability, growth and egg production performance of RIR pure line were significantly (P< 0.01) higher in D₂ dietary treatment groups as compared to D₁ and D₃ treatment. No significant difference (P< 0.05) in livability was found which could be attributed to the dietary SWP levels. Feed cost/kg was gradually declined on increasing dietary levels of SWP. The efficiency by the birds receiving SWP were better as compared to the control. The result of this study demonstrated that cheaper SWP could be an excellent substitute of costly protein concentrate in formulating diets for layers leading to increase profitability.

Program Area: Animal Health and Management

Commodity: Egg

Objectives:

To compare the growth and egg production performance of RIR pure line fed on different levels of SWP diet and to study the economic feasibility of SWP on layer ration.

Methodology:

The present study deals with evaluating SWP in a feeding trial using layer chicks (RIR pure line) and concluding SWP may be an efficient and economic substitute of protein concentrate (PC) under Bangladesh condition. SWP were collected from BRAC, Reeling centre, Dhaka office. The upper silk layer was discarded by heating with baking powder solution for 30 minutes and properly washed by using fresh water, sun dried and ground to powder and used as silk worm pupae meal (SWPM). A total number of sixty three day old layer chicks (RIR strain) were allocated randomly to three dietary treatments D₁ (6% PC+ 0% SVVP), D₂(0% PC+ 6% SNP), and D₃ (0% PC+ 8% SWP) each with 3 replications having 7 birds in each replication and each to receive 1- 3 diets formulated to be isonitrogenous and isoenergetic from 45 weeks of age. Replicate wise body weight gain, feed intake and mortality was recorded, feed efficiency and economics for each of the 3 diets were also calculated. After 20 weeks of age, egg production, body weight, egg weight, feed intake were also recorded for each of the 3 diets. All recorded and calculated data are input in computer for statistical analysis using analysis of variance (ANOVA) technique by a computer using a SPSS statistical computer package program in accordance with the principles of the Completely Randomized Design.

Achievement/Findings:

The effects of SWP on growth and production performance are good. The growth performance, egg production performance and profitability almost linearly increase up to 6% dietary levels. The result of this study demonstrated that cheaper SWP could be an excellent substitute of costly protein concentrate in formulating diets for layers leading to increase profitability.
