A COMPERATIVE STUDY ON LAYER FEEDS OF AFAQAL AND CP

Abstract

Feed represents the major cost of poultry production, constituting up to 70 percent of the total cost. Of total feed cost, about 95 percent is used to meet energy and protein requirements, about 3 to 4 percent for major mineral, trace mineral and vitamin requirements, and 1 to 2 percent for various feed additives. Poultry diets are formulated from a mixture of ingredients, including cereal grains, cereal by-products, fats, plant protein sources, animal byproducts, vitamin and mineral supplements, crystalline amino acids and feed additives. These are assembled on a least-cost basis, taking into consideration their nutrient contents as well as their unit prices. As the quality of feed is one of the main determinant factors in successful poultry farming; an attempt was made to compare the quality of commercial layer feeds to identify the different proximate component. For this two feed samples were collected from two specific places. CP feed sample was collected from a nearby shop of Chittagong metropolitan area and the other feed sample was collected from Animal Feed Analytical and Quality assurance Laboratory (AFAQAL) of VC&RI, Namakkal, Tamilnadu, India. The CP feed are commercially available in Bangladesh. Proximate analysis was done to see the nutritive values. Those values were then compared with the standard value. Finally both data of proximate analysis & economic one were compiled by using Microsoft Excel 2007 (Chi-square test by using SPSS 16.0). The proximate analysis of two feeds are showed the following ranges of nutrient compositions DM (88-90)%, Moisture (10.5-11.5)%, CP (16-18)%, CF (5-6)%, EE (3-4)%, Ash (6-6.6)%, NFE (53.2-55.05)%, ME (2666-2685) Kcal/kg. From this experiment, it was observed that the nutritive value of AFAQAL feed is comparatively better than CP feed as the nutritive values are very close to the specified values.
