Adult mallard ducks and northern bobwhite quail were exposed to 0, 10, 50, or 150mg perfluorooctane sulfonate (PFOS)/kg in the diet for up to 21 weeks. Adult health, body and liver weight, feed consumption, gross morphology and histology of body organs, and reproduction were examined. Due to mortality, birds exposed to 50 or 150mg PFOS/kg feed were terminated by Week 7. In quail, the lowest obs...

The control of mycotoxins is a global challenge not only in human consumption but also in nutrition of farm animals including aquatic species. Fusarium toxins, such as deoxynivalenol (DON) and zearalenone (ZEN), are common contaminants of animal feed but no study reported the occurrence of both mycotoxins in fish feed so far. Here, we report for the first time the occurrence of DON and ZEN in s...

the effects of different dietary levels of soybean oil (2, 4 and 6%) and probiotic primalac (0, 0.1 and 0.15 %) were investigated on performance and immune system of broiler chickens from day one to day 42 of age. for this purpose, five hundred and forty day-old male broiler chicks (cobb) in 9 groups of 60 each were used. the birds of each group were divided into 6 pens of 10 birds. the experim...

An experiment was carried out to determine the effect of dietary protein level on the specific activity of hepatic L-threonine dehydrogenase in young growing chicks. Six replicate pens of seven Leghorn chicks were fed semipurified diets containing 23, 27, or 32% CP with identical relative proportions of amino acids in each protein group. Body weights and feed consumption were measured for 3 d, ...

Two studies were conducted utilizing 270 chickens to evaluate the efficacy of yeast culture (YC) for both broiler and layer ayian types. In the first experiment, three dietary levels (0, 1.25, 2.50 percent) of YC were included in a nutritionally complete ration and fed to 14-day-old broiler chicks for 8 days. Body weight gain, feed consumption (g) and feed efficiency were not influenced by yeas...

Weights and individual feed consumptions of 160 beef, dairy and beef • dairy darns and their progeny were used to estimate several measures of life cycle cow efficiency. Efficiency was expressed as the ratio of ou tput to input, where output included relative values for slaughter weights, carcass weights and t r immed wholesale cut weights of progeny and weight of the dam, and inputs were prean...

The objective of the study was to verify the association of food intake and the dependence to be fed in hospitalized elderly individuals who were interviewed in the first 24 hours after admission to a general hospital. Participated in the research 75 individuals average 70.9 years old, being 58.7% male and 17.3% showing dependence to be fed. There was no evident association between dependence t...
