Abstract This research assessed the direct economic effects of the 2005–06 HPAI outbreaks on contracted turkey producers in Turkey in 2007. The data were obtained from 71 randomly selected, contracted turkey farms (producing 23% of the national turkey meat in Turkey in 2005) from five provinces for four integrated firms, which account for 67% of the national turkey production. Each farm was visited once for an oral interview conducted by the authors in 2007, using a questionnaire survey. The financial data before and after highly pathogenic avian influenza (HPAI) H5N1 outbreak periods were obtained from available financial records. Changes in production and economics parameters before and after the HPAI H5N1 outbreak periods were compared. In the analyses, the “before the HPAI H5N1 outbreak” period was stated as October 1, 2004, to May 31, 2005, whereas the “after the HPAI H5N1 outbreak” period was stated as the 8-mo between October 1, 2005, and May 31, 2006. The research revealed that changes in the technical parameters (number of hired labor, feed conversion rate, mortality rate, and the length of fattening period) were not found to be statistically significant at P > 0.05. However, there were severe effects of the HPAI H5N1 outbreaks on the economic parameters of the turkey production. The contracted turkey producers lost on average 0.9 cycles (38%) of production, and their management fees were reduced by 9.3% in the 8 mo after the outbreaks. As a result, the production level and enterprise income declined by 36% and 39%, respectively. About 93% of the producers did not do any other supplementary work during the idle production period; 59% of the producers had to use on average 4970TL (US

3200) from their personnel saving during the HPAI H5N1 outbreaks. About 62% of the producers stated that they had been considering expanding their businesses, but suspended the idea because of the outbreak, and 80% of the producers increased the biosecurity measures after the outbreaks. The futures of the contracted turkey producers are fully dependent on those of the integrated firms. Any negative effects on the latter appear to be directly transferred to the former. However, the government neglected contracted producers in the HPAI compensation programs.

This research aimed at assessing the financial effects of the 2005 to 2006 highly pathogenic avian influenza outbreaks on Turkish broiler enterprises. The data were obtained from an interview survey carried out in 499 enterprises randomly selected from 14 provinces that accounted for 79% of the national broiler production. The research revealed that the contracted broiler producers lost on average 1.38 cycles of production and their management fee reduced by 14.7% in 8 mo after the outbreaks. As a result, the broiler production and the enterprise income declined by 34.8 and 44.3%, respectively. The bank loan of the producers rose by 161%. A total of 93% of the producers did not do any other supplementary work during the idle production period in spite of the fact that broiler production was the only business of 36% of them. Furthermore, more than half of the producers (56%) stated that they were considering expanding their business, but suspended this idea due to the outbreak. Approximately 87% of the producers increased the biosecurity measures after the outbreaks. The nationwide effects of the avian influenza outbreaks on the contracted broilers farms were estimated to be US

Any negative effects on the latter appeared to be transferred directly to the former. However, the government neglected the integrated firms in the avian influenza compensation programs.

Özet: Bu araştırmada, Kayseri ili Damızlık Sığır Yetiştiricileri Birliği’ne üye 196 işletmedeki Holstein ırkı 1.705 ineğe ait toplam 3.814 laktasyon kaydı; ilkine buzağılama yaşı (İBY), buzağılama aralığı (BA) ve gebelik başına tohumlama sayısı (GBTS) yönünden incelenmiş ve bu parametrelerin hedef değerlerden sapması sonucunda meydana gelen mali kayıplar hesaplanmıştır. Araştırmada, ortalama İBY 821 gün, BA 403 gün ve GBTS ise 1.8 adet olarak hesaplanmış, aynı parametreler için hedeften sapmalar da sırasıyla 91 gün, 38 gün ve 0.1 adet olarak belirlenmiştir. Genel olarak, İBY ve BA’nda 1 günlük gecikme nedeniyle oluşan ortalama mali kayıp sırasıyla 15.6 TL/inek (10.4 US

A face to face survey was carried out in randomly selected 124 layer producers in 7 most important egg producing cities in Turkey between September 2006 and May 2007 in order to investigate the financial impacts of the Highly Pathogenic Avian Influenza (HPAI) outbreaks in Turkish commercial layer-egg producers. The financial analyses were divided into 3 periods, namely ‘before the outbreak (October 2004-January 2005)’, ‘during the outbreak (October 2005 - January 2006)’ and ‘after the outbreak (February-May 2006)’. Comparing the egg prices ‘before the disease’ with the situation during the outbreaks, the egg prices dropped from 0.091 YTL/egg to 0.038 YTL/egg. On average, the rate of capacity utilization, enterprise incomes and profits declined by 40%, 75% and 200% respectively. 14.5% of the producers had to stop production for about 5 months. 64.5% invested on average 6,648 YTL/enterprise to improve bio-security. The debts of the enterprises increased 3-4 folds due to the disease outbreaks, with 87% of the producers having to outlay an extra 153,426 YTL on average from their personal funds. In the ‘after the outbreak’ period, the prices and sales of table eggs recovered and even exceeded those of the ‘before the outbreak’ period, and the producers who managed to continue production appeared to be better off.
