Abstract/ Executive Summary:

A total of 990 Cobb 500 straight run day old chicks were housed on March 18, 2016 and reared up to April 1, 2016 to examine the effect of organic acids and essential oils on growth performances and health status at a village farm in Companigonj upazila under the district of Noakhali in Bangladesh. Body weight at 7 days of age and at 14 days of age were significantly higher for feed type two (159.99±0.16 g and 442.22±0.38 g, respectively). Average daily body weight gain at 8 to 14 days of age in feed type one was higher (41.09±0.03 g/d/b) than feed type two but higher feed conversion was recorded with feed type two (1.141) for the broiler birds of 14 days old. This study demonstrated that organic acids and essential oils supplementation in the broiler ration (feed type two) might help to increase the body weight and decrease mortality rate up to age of 14 days. It also revealed that feed to meat conversion might be increased through organic acids and essential oils supplementation. But to learn about the individual effect of organic acids preparation or essential oils preparations further study designing two feed types with similar nutrition in which one will be supplemented with organic acids and the other one with essential oils supplementation would be worthwhile.

Keywords: Organic acids, Essential oils, Commercial broiler, Bangladesh

Location: At a village farm in Companigonj upazila under the district of Noakhali in Bangladesh

Start Date: 18-03-2016

End Date: 01-04-2016

Program Area: Animal Health and Management

Commodity: Broiler

Objectives:

The present research work was done with the objectives to observe the effect of organic acids and essential oils on health and growth performances of commercial broiler chicken.

Methodology:

A total of 990 Cobb 500 straight run day old chicks were housed on March 18, 2016 and reared up to April 1, 2016 to examine the effect of organic acids and essential oils at a village farm in Companigonj upazila under the district of Noakhali in Bangladesh. Average day old body weight of chicks was 31.25 g per bird and their parent stock’s age was 26 weeks. An open side gable type broiler house with pacca floor and corrugated iron sheet made roof was used. Rice husk was used as litter materials. From the very first day, day old chicks were divided into two part in the same house. For feed type one a total of 500 day old chicks and for feed type two 490 day old chicks were housed. Individual weight was taken at 7 days of age and at 14 days of age. Same brooding and rearing environment was provided for both groups of birds. Two types of feed were used in two different groups of birds from the very first day and continued up to 14 days of age. Electric brooders were used. Two vaccines like Newcastle and Gumboro were administered as per manufacturer’s instructions. Same management was practiced in both part of the house. Only feed formulation was different. For part one feed type one and for part two feed type two were used. Major ingredients used to formulate feed used in the study Maize, Wheat flour, Rice polish, Soybean meals and oils, Meat & Bone meal, Limestone and Dicalcium phosphate etc.Organic acids and essential oils used in the feed were as like as below Organic acids and salts:A powerful combination of organic acids like propionic and formic acid and their salts ammonium propionate and ammonium formiate. Dose used: 2 kg per ton of feed. Essential oils and minerals: Essentials natural oils premix for poultry. Ingredients: Essential oils: 250 mg/kg, binder (silicic acid precipitated) 333.333 mg/kg, phosphorus 540 mg/kg, magnesium 185 mg/kg, sulphur 216 mg/kg. Dose used: 1 kg per ton of feed. Experimental design and data analysis The numbers of observations in different traits were unequal. So, the statistical design of the study was unbalanced factorial in nature. For having the descriptive statistics of traits like body weight at 7 days of age (BWT1) and body weight at 14 days of age (BWT2), average daily body weight gain at 1 to 7 days (ADG1) and at 8 to 14 days (ADG2) of age, SAS (2006) software was used. However, the least square means were obtained in SAS GLM using the following generalized linear model: Yi= μ + Bi+ei Where, Yi= Dependent variables (BWT1, BWT2, ADG1 and ADG2), μ = Overall population mean for any of the said trait; Bi = Effect of i^th feed type (where i = 1-feed type one and 2-feed type two), ei= Random residual error associated with Yi observation.

Achievement/Findings:

In conclusion, this study demonstrated that organic acids and essential oils supplementation in the broiler ration might help to increase the body weight and decrease mortality rate up to age of 14 days. It also revealed that feed to meat conversion might be increased through organic acids and essential oils supplementation. But to learn about the individual effect of organic acids preparation or essential oils preparations further study designing two feed types with similar nutrition in which one will be supplemented with organic acids and the other one with essential oils supplementation would be worthwhile.
