A 112-day experiment was conducted to economically evaluate the production of eggs from commercial layers submitted to diets supplemented with levels of plant extracts (dried turmeric powder) added or not to vitamin E. 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). The results calculated at work were favorable to the activity, and the items that most influenced the expenses in the effective production cost were: poultry, feed and labor, respectively. The best economic response in egg production was obtained by layers that consumed 100 IU/kg vitamin E and 0.2% turmeric;because the leveling point represents that the activity equals the revenues with the costs. The best profitability index was found in treatment that contained 50 IU/kg vitamin E and 0.1% turmeric com (16.78%).

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.

Microbiological control of feeds used in industrial poultry production has been increasingly important due to the demands of the market for food safety, as well as the need to ensure better quality of the digestive system of the birds. Microbiological analysis carried out in raw material used in feed production, especially feather, meat, and organ meal, has shown contamination by Clostridium perfringens. In order to study the presence of Clostridium perfringens, a total of 354 samples of feed and raw material were analyzed from January 2011 to July 2013. Samples came from four companies located in the state of São Paulo, with a total of 166 samples of meat meal, 24 samples of feather meal, 43 samples of organ meal, and 121 samples of feed. The following results were obtained: 88 (53%), 15 (62.5%), 16 (37.21%), and 23 (19%) samples were positive for Clostridium perfringens in each group of samples, respectively, with counts ranging from 2.0 × 102 to 7.0 × 103 CFU/g.

This work evaluated the effect of secondary bacterial metabolites produced by Pseudomonas sp LV strain in control of Lactobacillus sp. population in the microcosm of the vat during ethanol fermentation. The fraction F4 produced by Pseudomonas aeruginosa was extracted with dichloromethane and fractionating by vacuum liquid chromatography obtained in a methanol phase. The evaluation of antibiotic activity of F4 fraction mixed or not with sulphuric acid and Kamoram?. The antibiotic activity of F4 fraction was determined as well as the fermentation efficiency. Also was determined yeast cell viability, budding formation, the viability of budding cells, and number of populations of Saccharomyces cerevisiae and Lactobacillus sp. The results showed that the F4 fraction had high selective antibiotic activity against Lactobacillus sp. but not for S. cerevisae, and no inhibitory effect was observed in the fermentation process by yeast. Also F4 fraction decreased flocculation and foam formation. The F4 has an antibiotic activity against Lactobacillus sp. and should be used as an alternative to control bacteria contamination and foam and flocculation formation in the fuel ethanol fermentation process. The F4 fraction could reduce the use of antibiotics in the control of Lactobacillus sp. population during the fuel ethanol production.
