A 112-day experiment was conducted to evaluate turmeric and vitamin E levels on the productive performance and quality of hen eggs. A total of 432 20-week-old white layers were used, distributed in an entirely randomized design, in a 4 × 3 factor scheme (turmeric extract levels and vitamin E levels), with 6 repetitions of 6 birds per cage. The treatments consisted of four levels of turmeric extract inclusion (0;0.1;0.2 and 0.3) and three levels of vitamin E inclusion (0;50 and 100 IU/kg). Egg quality was evaluated at each 28-day cycle through the variables specific gravity, yolk percentage, albumen percentage, shell percentage and thickness, Haugh unit, yolk index and staining, and production performance: weight, egg production and mass, feed intake, feed conversion (kg/kg;kg/dz), and mortality. The addition of vitamin E alone worsened feed intake, egg weight and feed conversion of layers. Turmeric added to 100 IU of Vit E improved egg mass indices, Haugh Unit and yolk index and intensified yolk staining. The amount of turmeric used in this experiment was not sufficient to improve the performance or egg quality of the birds.

Braga Saldanha José Roberto Sartori Patrícia Helena Nogueira Turco Elisabeth Gonzales Renato Luis Luciano Greice Zanatta vitor barbosa fascina Agência Paulista de Tecnologia dos Agronegócios Polo Regional do Leste Paulista and UPD Brotas Secretariat of Agriculture and Supply to the State of São Paulo (SAA) Monte Alegre do Sul Brazil Faculty of Veterinary Medicine and Zootechnics Botucatu Campus State University of São Paulo Botucatu Brazil Advanced Center for Poultry Agribusiness Technological Research of the Biological Institute (SAA) Descalvado Brazil

In the commercial poultry chain, a great diversity of production systems is found to meet the needs of the market, since the consumer has become increasingly aware of the importance of the relationship between diet and health, which has encouraged researchers and the food industry to develop products enriched with nutrients capable of producing beneficial effects on health. There has been increasing progress in research aimed at including viable alternative products, such as plant extracts, in poultry diets, which have been shown to have an antimicrobial and antioxidant action and to promote improvements in animal performance. Turmeric (Curcuma longa L.) is a popular medicinal herb, which shows a wide range of pharmacological properties, such as antioxidant, antiangiogenic, antitumor, antivenom, antinflammatory, antimicrobial, antiproliferative, antiprotozoal, and antiaging. The use of turmeric in poultry production has been reported by many researchers. The aim of this review is to describe and report the most recent research on the use of turmeric as feed supplement for birds and so its effect on animal health and welfare.
