<![CDATA[Consumption of livestock products sensitives to changes in price and income. As people's wealth increases, they have the chance to consume a greater quantity and higher quality of these foods. This study examines the influence of increasing income on the quantity and quality of animal protein from livestock products consumed. National household expenditure survey data were used in this study particularly household in urban and rural area of D.I Yogyakarta Province (here after DIY Province). Based on Engel’s framework, we estimate income elasticities for both expenditure and quantity. Quality elasticity is derived as the difference between these two measures. The analysis is conducted for different household income levels. The result showed that income and household sociodemographic affected the expenditure and quantity demanded of beef, chicken, and eggs. Estimation of expenditure, quantity, and quality elasticity showed the consumer concerned about quantity compared to quality, but different for high-income households, which tend to be concerned with better quality products. Income is a primary determinant of consumption. For chicken and eggs, expenditure elasticity exceeds quantity elasticity, indicating a significant positive quality effect. As incomes rise, households purchase more expensive, higher-quality versions of these products. For beef, the pattern differs: lower and middle-income households prioritize increased quantity, with a shift towards quality only apparent among higher-income groups. The present study conclude that the development strategies is more focusing on increasing opportunities to generate income and improve the quality of livestock products. Policy efforts to improve nutritional outcomes must therefore focus on enhancing household purchasing power to facilitate access to both enough and higher-quality sources of animal protein.]]>
