Abstract/ Executive Summary:

A feed trial experiment was conducted with three different formulation on 30 White Leghorn (WLH) and 30 Rhode Island Red (RIR) layer birds, each group consisting of 10 birds during the period of 90 days from March to May 2000. These birds were fed on iso- nitrogenous and iso- energetic diets containing fishmeal (T₁), imported protein concentrate (T₃) and formulated protein concentrate (T₂) to assess the effect of replacing fish meal of the diet. Egg production among the three groups of WLH birds did not differ significantly (p>0.05), but increased significantly (p<0.05) in group T₃ RIR birds treated with imported protein concentrate mixture. However, it may be concluded that formulated protein concentrate can be used as a source of protein supplement in the ration of layer birds without any deleterious effects.

Start Date: 00-03-2000

End Date: 00-05-2000

Program Area: Animal Health and Management

Commodity: Feed

Objectives:

To formulate least cost protein concentrate mixture to reduce the cost of poultry feed and to save foreign exchange against import of protein concentrate.

Methodology:

The experiment was conducted at Bangladesh Livestock Research Institute (BLRI) poultry farm, Savar, Dhaka during the period from March to May 2000. The experiment was conducted with 30 laying Rhode Island Red (RIR) and 30 White leghorn (WLH) birds, which were distributed into three treatment groups, having 10 birds in each treatment groups as a replication. Birds of same age, sex and body weight were used. There were three different types of iso- nitrogenous and iso- energetic rations containing 17% CP and 2700 Kcal/ kg energy. The rations were well mixed and that was prepared for a period of 7 days .The ingredient and chemical composition of the formulated ration. Analysis of conventional and unconventional feed ingredients were completed. Some ingredient, which is containing high protein, have been grinder by grinder and mixed properly with specific measurement. The mixed feed samples have been analyzed for estimation of protein and other proximate component. This mixed protein mixture is stored properly for next feed formulation for feeding of poultry. The experimental design was based on complete randomized design (CRD).

Achievement/Findings:

All the treatments were equally effective and this result is supported that the vegetable protein with supplemental fish silage based feed did not affect on egg production against animal protein based feed. No significant influence was recorded in egg production among the three groups of WLH birds fed with three different rations but the RIR layer birds with imported protein concentrate mixture had significantly (p<0.05) increased the egg production. Formulated protein concentrate can be used as a source of protein supplement in the ration of layer birds without any deleterious effects.
