Abstract/ Executive Summary:

A total of 192, 14 days old as hatched broilers were fed ad libitum up to 56 days of age, on a control diet with 12% fish meal (FM) and 3 test diets; shrimp waste (SW) and/or marine waste (MW) and equal mixture of SW and MW completely replace dietary FM to have their effects on performance. Live weight and feed conversion improved and feed intake depleted on test diets than that on control. The test diets did not affect survivability of broilers. Complete replacement of FM by SW and/or MW reduced feed cost and production cost with increased profitability of raising broilers. Meat yield decreased on test SM and MW diets, but equal mixture of SM and MW, gave similar meat yield to that on control. It was concluded that equal mixture of SM and MW might be better, economic and efficient substitute of FM.

Objectives:

To assess the effect of FM of conventional broiler diet completely by SM or MW or equal mixture of SM and MW on performance and profitability.

Methodology:

The experiment was conducted at Bangladesh Agricultural University (BAU) Poultry Farm with 14 days old straight run broilers and continued up to 56 days. A total of 192 broilers were divided into 4 dietary groups having 4 replications in each and 12 broilers in each replication. The 4 dietary groups were D₁ (control diet with 12% FM), D₂ (test diet FM replaced 12% MW), D3 (Control FM diet replaced 12 % SW) and D4 (Control FM diet replaced 6% MW and 6% SW). Fresh and dried sawdust was used as litter at a depth of 5cm. Initially, the broilers were exposed to a continuous lighting of 23:30 hours and dark period of 30 minutes in each 24 hours. During night, electric bulbs were used to provide necessary light. Two experimental diets (broiler starter and broiler finisher) were formulated with locally available feed ingredients . Starter diet was fed from 14- 28 days and finisher diet was fed from 29-56 days of age. Feed and water were supplied ad libitum to the broilers throughout the experimental period. The area of each pen was 120cm x 90cm and was allotted for 12 broilers. Therefore, floor space for each broiler was 900cm2. Cost of production included expense on chick, feed, litter and medicine. Broiler cost was calculated from the purchasing cost. Litter and feed cost was calculated on the basis of market price. All recorded and calculated data were statistically analyzed using analysis of variance technique by an MSTAT Statistical Computer Package Program in accordance with the principle of Completely Randomized Design (Steel and Torrie 1960). Least significant differences (LSD) were calculated to compare variations among diets where ANOVA showed significant differences.

Achievement/Findings:

Resulted scenario indicates that mixture of unconventional 6% shrimp waste and 6% marine waste might be an efficient replacer of fish meal to formulate economic diets.
