CHAPTER 4 ENERGY CONSUMPTION STATUS IN<br />

POULTRY FARMS<br />

<strong>The</strong> poultry farms <strong>in</strong> Gazipur district are covered by the national electricity grid. Gazipur<br />

Palli Bidyuit Samity (PBS) a rural electric cooperative under Bangladesh Rural<br />

Electrification Board (REB) is responsible for the commercial operation <strong>of</strong> electricity <strong>in</strong> the<br />

district. All most all the poultry farms are grid connected. <strong>The</strong>re is a huge power shortage <strong>in</strong><br />

the study area as well as <strong>in</strong> the country. For un<strong>in</strong>terrupted power supply some poultry farms<br />

use back up system such as diesel generator. On the other hand, to avoid the power<br />

<strong>in</strong>terruption there are a very few large scale farms which are not grid connected and have<br />

<strong>in</strong>dependent power plants based on natural gas. <strong>The</strong> daily energy consumption pattern <strong>in</strong><br />

poultry farms is almost similar. Usually, the farms consume less energy <strong>in</strong> the day time and<br />

consume more <strong>in</strong> the even<strong>in</strong>g. However, the farms us<strong>in</strong>g energy efficient lamps use less<br />

electricity <strong>in</strong> the even<strong>in</strong>g than day time. Few poultry farms <strong>in</strong> the district have biogas plants.<br />

<strong>The</strong> majority <strong>of</strong> the bio gas plants are undersized as compared to its total potential. Three<br />

poultry farms <strong>in</strong> the district currently produce electricity <strong>from</strong> biogas dur<strong>in</strong>g the power<br />

outage. <strong>The</strong> other poultry farms use biogas for thermal purposes ma<strong>in</strong>ly for household<br />

cook<strong>in</strong>g. <strong>The</strong> details <strong>of</strong> utilization <strong>of</strong> different types <strong>of</strong> energy <strong>in</strong> the poultry farms are<br />

discussed <strong>in</strong> this chapter.<br />

4.1 EXISTING UTILIZATION OF ELECTRICITY<br />

4.1.1 <strong>Electricity</strong> consumption <strong>of</strong> major electrical appliances used<br />

<strong>Electricity</strong> is <strong>in</strong>evitable for the production <strong>of</strong> eggs and for the growth <strong>of</strong> the birds as well.<br />

<strong>Electricity</strong> is used <strong>in</strong> the <strong>in</strong>dustry ma<strong>in</strong>ly by lamps to provide proper light<strong>in</strong>g <strong>in</strong> the poultry<br />

shed, fans to ma<strong>in</strong>ta<strong>in</strong> the required temperature, brooder to brood up the chicks and the water<br />

pumps to supply water. Follow<strong>in</strong>g are the details <strong>of</strong> the status <strong>of</strong> electricity use for the ma<strong>in</strong><br />

appliances <strong>in</strong> the poultry farms.<br />

Use <strong>of</strong> Lamp<br />

For the optimum production <strong>of</strong> eggs and the normal growth <strong>of</strong> birds it requires 16 - 17 hours<br />

light<strong>in</strong>g a day (Ghoshal, 2005, p, 119). Normally, <strong>from</strong> 6 am to 6 pm is considered as day<br />

light and no artificial light<strong>in</strong>g is required dur<strong>in</strong>g this period. However <strong>in</strong> some dark days it<br />

may require some additional light<strong>in</strong>g dur<strong>in</strong>g the period. Usually, artificial light<strong>in</strong>g is required<br />
