A COMPERATIVE STUDY ON DIFFERENT LAYER FEEDS

Comparative Study on Different Layer Feeds ABSTRACT Feed represents the major cost of poultry production, constituting up to 70 percent of the total. 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. 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 3 feed samples were collected from 3 layer farms, randomly selected & which are located scattered in different areas of Chittagong district. The 3 feed are commercially available in Bangladesh. They are CP, PARAGON, NOURISH feed. Proximate analysis was done to see the nutritive values. Those values were then compared with the standard and company 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 3 feeds showed the following ranges of nutrient compositions: DM 88-90% Moisture 10-12% CP 16-20% CF 4-6% EE 3-4.3% Ash 6-6.8% NFE 53.2-58.6% ME 2632-2743Kcal/kg Key Words: Feed, layer layer, proximate analysis, DM, ME, CP, CF, EE, Ash, NFE.
