OBJECTIVES This systematic review of cohort studies aimed to identify any association between specific dietary patterns and risk of colorectal cancer (CRC). Dietary patterns involve complex interactions of food and nutrients summarizing the total diet or key aspects of the diet for a population under study. METHODS AND MATERIALS This review involves 6 cohort studies of dietary patterns and th...

Background: The application of phytogenic additives in the form of essential oils have attracted considerable attention in poultry industry. OBJECTIVES: An experiment was conducted to evaluate effects of the blends of essential oils (EO) isolated from some medicinal plants including savory, thyme, fennel and rosemary on performance, blood metabolites, intestinal microflora, and meat quality of...

Women of childbearing age are at risk of Fe deficiency if insufficient dietary Fe is available to replace menstrual and other Fe losses. Haem Fe represents 10-15 % of dietary Fe intake in meat-rich diets but may contribute 40 % of the total absorbed Fe. The aim of the present study was to determine the relative effects of type of diet and menstrual Fe loss on Fe status in women. Ninety healthy ...

This experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (PBPM) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. Three samples of PBPM produced in Ardabil province located in northwest of Iran, were provided during one month sampling peri...

Background: Mycotoxins are a group of structurally diverse substances produced by a wide range of moulds. These fungal secondary metabolites, whose presence in feed is unavoidable, can impose hazards to human and animal health. Continuous concern about potential effects of mycotoxins in the human diet has led to an increasing interest in researches about fungi and mycotoxin production. The aim ...

Poultry fat has become a more economical source of energy than byproducts currently used. Therefore, this study was conducted to determine the effects of dietary fat source (poultry fat or beef tallow) in finishing diets for cattle on the fatty acid composition of beef. Sixty Angus crossbred steers (410.8 kg initial BW) were stratified by source, blocked by weight, and assigned within block to ...

introduction the occurrence of mycotoxins in foods and feeds is a problem of major concern in all over the world. profitability of poultry production can be greatly affected due to the frequency of feed contamination and the detrimental effects of these toxins on the performance. aflatoxins, a group of closely related and biologically active mycotoxins, are produced by strains of aspergillus fl...

BACKGROUND Processed meat and fish have been shown to be associated with the risk of advanced prostate cancer, but few studies have examined diet after prostate cancer diagnosis and risk of its progression. OBJECTIVE We examined the association between postdiagnostic consumption of processed and unprocessed red meat, fish, poultry, and eggs and the risk of prostate cancer recurrence or progre...

A laboratory air emission evaluation system consisting of eight emission vessels (19 L each) has been developed and used to investigate the effects of bio/chemical agents or feed additives on ammonia and odor emissions from poultry manure. A novel approach was used to evaluate volatile organic compounds (VOCs) and odor emissions, featuring air sampling with carboxen/PDMS 85 micrometer SPME fibe...

The characteristics of an endoglucanase produced by a Trichoderma virens strain T9 newly isolated from a palm-fruit husk dump site, its physiological characteristics and enzyme production were studied. Whole cells of the depolymerizing-enzyme producing T. virens were applied to palm-fruit husk and bird performance characteristics when employed as poultry diet additive were considered. Endogluca...
