We investigated the expression of bcl-2, estrogen receptor alpha (ER-alpha), caspase-3, -8, -9, proliferating cell nuclear antigen (PCNA) and Ki-67 in canine mammary carcinomas. We used 65 paraffin embedded and re-diagnosed archival canine mammary tumor samples to which we applied the routine streptavidin-biotin-peroxidase technique. Seventeen cases were re-diagnosed as tubulopapillary carcinoma, 31 were re-diagnosed as complex carcinoma and 17 were re-diagnosed as carcinosarcoma. Differences of expression of bcl-2 and PCNA were statistically significant according to tumor type. Differences in expression of ER-alpha, caspase-3, -8, -9 and Ki-67 were not statistically significant. Differences of expression of bcl-2 and PCNA were statistically significant compared to ER-alpha, caspase-3, -8, -9 and Ki-67 in carcinosarcomas. We report the prognostic significance of bcl-2 and PCNA expression in canine mammary carcinosarcomas.

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$100.8 million (US$7,967/broiler house). The futures of the contracted broiler producers are fully dependent upon those of the integrated firms. 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.

This study was intended to determine whether there was any difference between the parameters of herd size and milk yield based on the hypothesis that the dairy cattle enterprises in the Teke Region used different production methods depending on their herd size. Total milk yield and 305-d milk yield were increased in parallel with the farm-scale and reached 8968.70 ± 124.56 kg and 7632.20 ± 79.67 kg, respectively, in the farms with the largest scale of 101 heads and above (p < 0.001). It was further determined that milk yield decreased significantly in the summer calving season compared to other seasons (Summer: 7897.20 ± 154.48 b, Autumn: 8344.80 ± 169.33 a, Winter: 8054.50 ± 127.22 a, Spring: 8133.60 ± 159.77 a) (p < 0.01). Heat stress is thought to be the reason for the low milk yield in the summer season compared to other seasons. It was shown that the small-scale farms with 1–10 cows had the longest lactation length (394.90 ± 6.90 days) (p < 0.001). It was also determined that there is a directly proportional and significant relationship between the lactation number of Holstein cattle and lactation milk yield and 305-d milk yield values (p < 0.01). It was determined that dairy cattle in the 5th lactation had the highest 305-d milk yield value with 6992.00 ± 164.40 kg. In conclusion, a positive statistical correlation was found between the scale of dairy farms and their milk production parameter.
