New opacity distribution functions (ODFs) for several metallicities have been computed. The main improvements upon previous ODFs computed by Kurucz (1990) are: (1) the replacement of the solar abundances from Anders & Grevesse (1989) with those from Grevesse & Sauval (1998); (2) the replacement of the TiO lines provided by Kurucz (1993) with the TiO lines from Schwenke (1998), as distributed by...

Drilled seeds are an important food resource for many farmland birds but may pose a serious risk when treated with pesticides. Most compounds currently used as seed treatment in the EU have low acute toxicity still affect sub-chronic or chronic way, especially considering that sowing season lasts several weeks months, resulting long exposure period birds. Tebuconazole is triazole fungicide wide...

The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...

The fatty acid composition of the intramuscular lipids of cattle, pigs and birds were determined relative to breed and feeding regime. The cattle included Yellow Cattle, Hereford and Japanese Black; pigs included Wild-boar, Touyuens and Yorkshires; the birds were Wild-birds, Jungle-fowl and broilers. The pen fed animals such as Japanese Black cattle and Yorkshire pigs had a higher amounts of ol...

from the last few years, the inclusion of microbial phytase in poultry diets has increased significantly, mainly in response to heightened concerns over phosphorus pollution of the environment and as cheaper means to make phosphorus available to birds from phytate. phytate is the major form of phosphorus, abundantly found in cereal grains, beans and oilseed meals used in poultry diet but the mo...
