Light Management â€“
a)Â Use of Fluorescent Tube Light in place of Incandescent Bulbs â€“ Earlier, in most of the poultry farms incandescent bulbs were being used for providing light to the birds. The Rule of Thumb has been 40-watt incandescent bulb, per 100-sq. ft. area of a poultry shed at 10â€™ distance. With the experiments conducted at the Institute, we have advocated use of fluorescent tubes in place of incandescent bulbs in poultry sheds.
As the fluorescent tube provides better illumination than bulbs, we can reduce the light points in poultry shed to 1/3rd, compared to the shed using 40-watt bulbs. 40-watt fluorescent tube provides good illumination up to 300 sq.ft. area i.e. at a distance of 30â€™ in a shed, reducing energy bill to 1/3rd. This has now been a common practice in most of the Poultry farms.
b)Â Use of Compact Fluorescent Lights (CFLs) vis-Ã -vis Fluorescent Tubes of 40-watt in layers. â€“ With the use of 40-watt Fluorescent Tube, the requirement of light points in layer shed is reduced to 1/3rd, effecting saving of 66.67% in energy bill.
Recently, many electrical companies have introduced 18-watt Compact Fluorescent Lights (CFLs). The experiment has been conducted to replace the Fluorescent Tubes with Compact Fluorescent Lights and it has been observed that there is no significant difference in the Average Egg Production and Mortality %, in the shed using CFLs. There is additional 50% saving in energy bill by use of CFLs in layer farms.
The initial investment cost of CFL is higher than the Fluorescent Tubes. However, The life of CFL is claimed to be five times more than that of the tube. As such, with the lower energy consumption, it would be economical and profitable for a poultry farmer to switch over from 40-watt tube to 18-watt CFL.
