Tartrate-resistant acid (ACP) and alkaline phosphatase (ALP) activities were evaluated in the serum and bone of broiler chicks fed with various amounts of non-phytate phosphorus (NPP) or phytase. Data were analysed using a 4×3 factorial design containing four NPP levels per period. Analyses were performed in chicks aged 1-21 days (0.21; 0.29; 0.37; 0.45 ppm) and 36-42 days (0.13; 0.21; 0.29; 0.37 ppm) and under three different phytase level treatments (0, 500 and 1000 FTU/kg) for each period. In 42-day-old animals, the serum ACP and ALP activities did not differ in response to NPP and phytase levels and bone ACP activity decreased with increased phosphorus levels. We observed effects on ALP activity by approximately 70% in lower phosphorus (0.13 and 0.21) levels without phytase. The phytase addition decreased (P<0.05) ALP values in lower phosphorus levels. The bone ALP and ACP levels of 21-day-old animals were not affected by phosphorus or phytase. Pi depletion induces a significant increase in alkaline phosphatase synthesis, suggesting that the function of this enzyme is downregulated by phosphorus. © 2013 Copyright Taylor and Francis Group, LLC.

Purpose: The purpose of this paper was to evaluate the impact of some labeling aspects on the consumer intent to purchase ready to drink orange juice and nectar. Design/methodology/approach: The influence of label information on the consumer intent to purchase was evaluated by conjoint analysis using a convenience sample (n=149). A factorial design with four characteristics, price, brand, information about the product and kind of beverage, was used. Three levels were established for brand and product information, and two for price and kind of beverage. Findings: Low price, product information and market leading brand had positive impact. No preservatives/natural was the information that most influenced consumer's purchase intent. The ideal label showed the leading brand, low price and information no preservatives/natural. These results could be useful for strategic planning of consumer instruction and have important implications for Brazilian orange juice manufactures. Originality/value: Although the most widely consumed beverages in Brazil are ready to drink orange juice and nectar, it was unexpected that consumers did not know the differences between them and that kind of beverage was not an important factor for the purchase decision. © Emerald Group Publishing Limited.
