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.

    INFORMATION TO USERS This material was produced from a microfilm copy .of the original document. While the most aclvanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original sUbmitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing pagels) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again - beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

  • Easter Customs Since Its Origins, Easter Has Been a Time Of

    Easter customs Since its origins, Easter has been a time of celebration and feasting and many Traditional Easter games and customs developed, such as egg rolling, egg tapping, Pace egging and egg decorating. Today Easter is commercially important, seeing wide sales of greeting cards and confectionery such as chocolate Easter eggs, marshmallow bunnies, Peeps, and jelly beans. Even many non-Christians celebrate these aspects of the holiday while eschewing the religious aspects. Easter customs in English-speaking world Marshmallow bunnies and candy eggs in an Easter basket. In some cultures rabbits, which represent fertility, are a symbol of Easter. Throughout the English-speaking world, many Easter traditions are similar with only minor differences. For example, Saturday is traditionally spent decorating Easter eggs and hunting for them with children on Sunday morning, by which time they have been mysteriously hidden all over the house and garden. Other traditions involve parents telling their children that eggs and other treats such as chocolate eggs or rabbits, and marshmallow chicks (Peeps), have been delivered by the Easter Bunny in an Easter basket, which children find waiting for them when they wake up. Many families observe the religious aspects of Easter by attending Sunday Mass or services in the morning and then participating in a feast or party in the afternoon. Some families have a traditional Sunday roast, often of either roast lamb or ham. Easter breads such as Simnel cake, a fruit cake with eleven marzipan balls representing the eleven faithful apostles, or nut breads such as potica are traditionally served. Hot cross buns, spiced buns with a cross on top, are traditionally associated with Good Friday, but today are often eaten well before and after.
