The Welfare of Animals in the Turkey Industry

The natural behavior and habitat of wild turkeys stand in sharp contrast to the life of turkeys commercially raised for meat. Overcrowded in automated, barren "grow-out" houses, turkeys are offered little opportunity to display their full range of complex social, foraging, and exploratory behavior. Today's commercial breeds grow at an unnaturally rapid pace to unprecedented weights. This forced rapid growth further compromises their health and welfare, and causes them to suffer from skeletal, muscular, and other health problems, as well as painful and often crippling leg disorders. Breeding birds, unable to mate naturally due to genetic selection for fast growth and excess breast muscle (meat), must be continuously feed-deprived in order to control weight. The catching, transport, and slaughter of turkeys subject them to stress, injury, and pain

Structure and age-dependent development of the turkey liver: a comparative study of a highly selected meat-type and a wild-type turkey line

In this study the macroscopic and microscopic structure of the liver of a fast growing, meat-type turkey line (British United turkeys BUT Big 6, n = 25) and a wild-type turkey line (Wild Canadian turkey, n = 48) were compared at the age of 4, 8, 12, 16, and 20 wk. Because the growth plates of long bones were still detectable in the 20-week-old wild-type turkeys, indicating immaturity, a group of 8 wild-type turkeys at the age of 24 wk was included in the original scope of the study. Over the term of the study, the body and liver weights of birds from the meat-type turkey line increased at a faster rate than those of the wild-type turkey line. However, the relative liver weight of the meat-type turkeys declined (from 2.7 to 0.9%) to a greater extent than that of the wild-type turkeys (from 2.8 to 1.9%), suggesting a mismatch in development between muscle weights and liver weights of the meat-type turkeys. Signs of high levels of fat storage in the liver were detected in both lines but were greater in the wild-type turkey line, suggesting a better feed conversion by the extreme-genotype birds i.e., meat-type birds. For the first time, this study presents morphologic data on the structure and arrangement of the lymphatic tissue within the healthy turkey liver, describing two different types of lymphatic aggregations within the liver parenchyma, i.e., aggregations with and without fibrous capsules. Despite differences during development, both adult meat-type and adult wild-type turkeys had similar numbers of lymphatic aggregations

Where Turkey stands in Europe and why it should be admitted to the EU

Turkeys position relative to Europe is analyzed from three different perspectives, i.e (i) the semi-official perspective of the Copenhagen criteria, the Maastricht criteria and the Lisbon strategy, (ii) the perspective of comparative surveys, and (iii) the perspective of key European worries regarding future strains on cohesion funds and the complex relationship of the Turkish population to European values. It is shown that Turkeys standing in international comparisons of good governance has been improving in recent years and that the country is on a path of convergence with the Maastricht criteria. Turkey falls considerably short, however, of the employment and education goals of the Lisbon agenda. Comparative surveys show the Turkish population to have not only a low standard of living, but also a very low level of satisfaction with life and with public services, to have comparatively little trust in other people and a low level of civic engagement, and to nourish traditional attitudes concerning religious beliefs, womens rights and gender roles. Since Turkeys admission to the EU would enlarge the EU population by 15 %, but economic output by less than 3 %, Turkeys accession would severely strain EU cohesion funds. Despite these reservations, Turkeys admission to the Union is here advocated for three reasons: (1) Risks of a fundamentalist backlash against Europe would considerably increase if the long-standing accession promise were not kept. (2) Given that the country is entering a very favourable demographic phase for about 2-3 decades, there is considerable economic opportunity with a vast growth potential. (3) Since the recent Eastern enlargements have already decided the debate between federalists and inter-governmentalists in favour of the latter, Europe has more to gain than to lose from Turkeys membership which would strengthen the countrys ties to the West, and provide a chance of proving to the world that the motto of the European Union united in diversity is a better model for the future of international relations than the scenario of a clash of civilizations. --

Comparative aspects of phytase and xylanase effects on performance, mineral digestibility, and ileal phytate degradation in broilers and turkeys

Two experiments were performed, using broilers or turkeys, each utilizing a 3 × 2 factorial arrangement, to compare their response to phytase and xylanase supplementation with growth performance, nutrient digestibility, and ileal phytate degradation as response criteria. For both experiments, 960 Ross 308 or 960 BUT 10 (0-day-old) birds were allocated to 6 treatments: (1) control diet, containing phytase at 500 FTU/kg; (2) the control diet with xylanase (16,000 BXU/kg); (3) the control diet supplemented on top with phytase (1,500 FTU/kg); (4) diet supplemented with 1,500 FTU/kg phytase and xylanase (16,000 BXU/kg); (5) the control diet supplemented with phytase (3,000 FTU/kg); and (6) diet supplemented with 3,000 FTU/kg phytase and xylanase (16,000 BXU/kg). Each treatment had 8 replicates of 20 birds each. Water and diets based on wheat, soybean meal, oilseed rape meal, and barley were available ad libitum. Body weight gain and feed intake were measured from 0 to 28 D, and feed conversion ratio (FCR) corrected for mortality was calculated. Ileal digestibility for dry matter and minerals on day 7 and 28 were analyzed in addition to levels of inositol phosphate esters (InsP6-3) and myo-inositol. Statistical comparisons were performed using ANOVA. Xylanase supplementation improved 28D FCR in broilers and turkeys. Increasing doses of phytase reduced FI and improved FCR only in broilers. In broilers, the age × phytase interaction for phosphorous digestibility showed that increasing phytase dose was more visible on day 7, than on day 28. Mineral digestibility was lower in 28-day-old turkey compared with 7-day-old turkey. InsP6 disappearance increased with increasing phytase levels in both species, with lower levels analyzed in turkeys. InsP6 disappearance was greater in younger turkeys (day 7 compared with day 28). In conclusion, although broilers and turkeys shared several similarities in their growth and nutrient utilization responses, the outcomes of the 2 trials also differed in many aspects. Whether this is because of difference in diets (InsP or Ca level) or differences between species needs further investigation

Competitiveness of Turkeys Organic Exports in the European Union Market

Turkeys exports of organically produced agricultural products have been rapidly growing particularly in response to increasing demand in the European Union countries. Common view and findings of the research on organic trade in Turkey confirms that European market is expanding. A lacking component of the existing research on Turkeys organic exports is that none of the studies focused on modeling the export market for organic products which would enable to make forecasts as well as to make analysis for policy implications. Another missing component of the stream of studies on trade of Turkish organic commodities is the lack of understanding of the present situation of the competitiveness of Turkish exports in the European Union market. The study therefore focuses on estimating an econometric export demand function for organic products and exploring the competitiveness and export performance of Turkish exports as well as understanding the components of export performance. An effort to estimate an econometric export demand model for Turkeys organic exports and revealing sources of export performance and competitiveness is what makes the present study a unique one. The project has three major objectives and thus seeks to produce three outputs: The first objective is to estimate an export demand model for Turkish organic products in the European Union market. It is therefore possible to estimate price and income elasticities of demand as well as to make projections. The second objective is to explore Turkeys export competitiveness in organic products in the European Union market. It order to fulfill this objective, we will estimate indices to measure Turkeys competitiveness. The third objective is to investigate export competitiveness and determine the components of export performance. Through constant market share analysis, we seek to determine the key factors underlying the growth or Turkeys organic exports. The study reveals that export demand for the Turkish organic products are growing and sensitive to price and income changes in target countries. Turkey has a clear comparative advantage against the rival EU countries in selected products. Competitiveness is particularly due to relative prices, thus does not indicate a sustainable competitiveness due to lack of added value in the export items.Organic Agriculture, Turkish Agriculture, Export Demand, Competitiveness, Turkish Organic Exports, International Relations/Trade, Livestock Production/Industries,

Survey of Diseases in Wild Turkeys in Arkansas

Nineteen dead wild turkeys were necropsied and 573 live wild turkeys were physically examined for pathological agents in Arkansas between 1992 and 1997 to determine the proximate role disease may play in declining wild populations in Arkansas. Necropsy of the dead wild turkeys identified avian pox and histomoniasis as the most common diseases (16% and 11% of necropsies, respectively). Avian pox was recorded from three major physiographic regions in the state (Ozark Highlands, Ouachita Mountains, Gulf Coastal Plain). One hen died of non-accidental crop impaction, the fifth occurrence observed in the southeastern United States. Another hen died after developing severe, focal necrotic dermatitis caused by a Penicillium sp. fungus, the first occurrence observed in wild turkeys. All live wild turkeys appeared free of gross signs of disease. We found diseases in wild turkeys in Arkansas are not uncommon and are more diverse than previously reported. Continued monitoring of disease in wild turkeys is therefore encouraged

Effect of crude protein concentration and dietary electrolyte balance on litter quality, foot pad dermatitis, growth performance and processing yields in two medium heavy turkey hybrids

1. An experiment was conducted to investigate the effect of crude protein (CP) concentration and dietary electrolyte balance (DEB) on growth performance, processing yields, litter quality and foot pad dermatitis (FPD) in male turkeys from two commercial hybrids. Soya bean meal was replaced by vegetable protein sources selected for lower K concentrations to lower DEB in order to improve litter quality and subsequent quality of foot pads.2. Effects of CP on litter friability and wetness were not consistent during the production period. FPD in turkeys fed on diets with low CP was significantly lower than FPD in turkeys fed on diets with high CP until 84 d. Growth performance was adversely affected at low CP. Processing yields were not affected by CP.3. Litter was significantly dryer in pens of turkeys fed on diets with low DEB than in pens of turkeys fed on diets with high DEB. FPD in turkeys fed on diets with low DEB was significantly lower than in turkeys fed on diets with high DEB. Growth performance and processing yields were adversely affected at low DEB.4. FPD in turkey hybrid A was higher than in turkey hybrid B at 28 d of age. Thereafter, no differences in FPD between turkey hybrids were observed. Growth performance and processing yields were not affected by turkey hybrid.5. Overall, a significant interaction effect of CP × DEB was observed for FCR: in turkeys fed on the high DEB treatment, FCR of turkeys fed on the high CP diets was lower than FCR of turkeys fed on the low CP (LCP) diets whereas on the low DEB treatment, FCR was not affected by CP treatment.6. It was concluded that litter quality can be improved and FPD may be decreased in turkeys fed on diets containing lower CP and DEB levels.<br/
