ABSTRACT Investigating the factors that affect broiler chicken prices in Turkey is vital for understanding market formation. The parameters and factors likely to influence the price of broiler chicken were analyzed for the period between 2010-2020 in Turkey. The study adopted the boosting regression model to predict the correlation between broiler chicken consumer price and variable factors like broiler feed, corn, soybean meal, wheat prices, the dollar exchange rate, producer price index (PPI), and agricultural PPI. The accuracy of the estimation of the regression model created according to the results of the analysis was calculated as 86%. The producer price index variable caused the highest relative impact (25.63%) on broiler chicken meat prices. The highest positive correlation was obtained between the producer price index and the agricultural PPI (r = 0.984). Thus, it was determined that chicken prices were affected by feed raw material prices and the general economic conditions in Turkey. In addition to improving the prevailing economic conditions, an effective price control mechanism is required to prevent excessive price fluctuations in the sector. Simultaneously, it is essential to create policies to reduce input costs.

RESUMO O presente estudo teve como objetivo calcular os escores de qualidade de vida (SF-36) de estudantes de veterinária na Turquia e revisar seus escores no que diz respeito a diferentes características sociodemográficas. Um total de 1211 estudantes de medicina veterinária em 26 faculdades diferentes na Turquia foram selecionados pelo método de amostragem estratificada e foram questionadas sobre o consumo e as despesas com alimentos de origem animal usando o questionário SF-36 entre outubro e dezembro de 2018. Diferenças significativas foram encontradas entre os participantes do SF-36 em termos de nível do ano, gênero, status de acomodação, nível de renda e nível de gastos com alimentos e alimentos de origem animal (P <0,01). Com o aumento do orçamento reservado para produtos de origem animal, as pontuações nos domínios de funcionamento físico, vitalidade, saúde mental, dor e percepção geral de saúde também aumentaram e foram encontradas diferenças estatisticamente significativas (P <0,01). Os baixos índices de qualidade de vida dos veterinários podem ser melhorados, aumentando o nível de renda e o consumo de alimentos de origem animal. Isso garantirá mais energia e que tenham o nível desejado de percepção mental e geral de saúde.

ABSTRACT The present study aimed to calculate the quality of life scores (Short Form-36) of veterinary students in Turkey and review their scores with regards to different socio-demographic characteristics. A total of 1211 students studying veterinary medicine in 26 different faculties in Turkey were selected by stratified sampling method and were asked questions concerning their consumption of and expenditures on foods of animal origin using the SF-36 questionnaire between October and December 2018. Significant differences were found between SF-36 components in terms of year level, gender, accommodation status, income level, and level of expenditures on foods and foods of animal origin (P<0.01). With the increase in the size of the budget set aside for animal products, the scores in the domains of physical functioning, vitality, mental health, pain, and general health perception also enhanced, and statistically significant differences were found (P<0.01). The low quality of life scores of the veterinary students can be improved by increasing their income level and consumption of foods of animal origin. This will ensure that they are energetic and have the desired level of mental and general health perceptions.

ABSTRACT This study aimed at determining the total losses associated with the season, transportation distance, and slaughter age during the transportation of broilers from poultry farms to slaughterhouses in Turkey. All data and parameters were statistically analyzed and the change in total loss during transportation was evaluated by two-way analysis of variance to determine which factors or variables affect this change. Total transportation losses were compared among the four seasons of the year, two slaughter ages (younger broiler, 31-39 days of age; older broilers 40-46 days of age) and three distance ranges (short, ≤50 km; medium, 51-150 km; and long, ≥151 km). Total losses of 259.40 g, 307.35 g, and 350.14 g were determined for short, medium and long distances, respectively, indicating that losses increased with transportation distance (p<0.05). Broilers slaughtered at a younger age presented lower total losses than those slaughtered at an older age (p<0.05). When seasons were evaluated, the highest total loss was determined in the summer, which was not statistically different from that calculated for autumn, whereas total transportation losses in spring and winter were found relatively lower. The study showed long-distance transportation in the winter considerably increased total losses to levels similar to those obtained in the summer.
