Ranade 57-B, Townshend Road, Kolkata - 700025 INDIAN POULTRY REVIEW | 03 The Edit AN OPPORTUNITY AHEAD The good news in our fight and challenge against the COVID-19 menace is that our poultry industry has restored itself to near-normalcy in three- fourths of the country. These areas have seen no or only a few cases of the virus infection. The bad news, however, is that economic activity is located disproportionately across the country and the timetable for reviving poultry industry and economic progress in some areas is uncertain. In the near term, there is added uncertainty of a severe wave of avian influenza infection in many states. Bird flu has seen two major waves in 2006-2007 and again in 2008-2009. The recent bird-flu episode in 2020- 21 killed and destroyed (as a precautionary measure), a large number of birds in some states of the country. Only in Maharashtra, the number of destroyed birds exceeded more than a million. Prospects of overcoming these challenges and returning to full normalcy for the poultry industry are far more certain in one to one and a half years. The team piloting these poultry reviving projects says that the industry will come back to the previous form at pre COVID-19 level as early as the end of 2021. While the government must accord priority to meeting the immediate challenges posed by COVID-19 and avian indfluenza, it is also time to begin strategising for the longer term economic transformation. As the saying goes, never let a crisis go to waste. While the sequencing of steps to restart the poultry economy after the lockdown must be the topic of the day, we must also cast our eyes a little further ahead to opportunities that will emerge after the crises. We must avail the opportunities opened for poultry producers through poultry processing. In a recent report it has been pointed out that after this pandemic crisis, the demands for processed poultry meat have grown significantly to 18-22% globally, and in our country the demand has crossed more than 15 to 16% from 8 to 9% in pre-COVID times. Our poultry industry must avail this opportunity. G. N. Ghosh Managing Editor INDIAN POULTRY REVIEW | 05 Indian Research intensive poultry and livestock production.
