objective(s): hyperthermia is one of the most common environmental stressors that affect multi-biological systems in the body including the central nervous system as well as the hematopoietic organs. the objective of the present study was to investigate the protective role of ethanolic extract of propolis (eep) on some selective stress markers, hematological, biochemical, and histopathological ...
introduction poultry meat enriched with long-chain polyunsaturated fatty acids n-3 (pufa lc n-3) can make a nutritionally meaningful contribution to western diets in which consumption of pufa lc n-3 is low. enrichment of poultry meat with this fatty acid is usually achieved by inclusion of fish oil in broiler diet (23, 24). however, meat enriched in this way is susceptible to quality deteriorat...

The trace elements such as selenium can be included in the diet from a variety of sources. The purpose of this study was to investigate the effects of incorporation of inorganic, organic and nano selenium in the diets of dairy calves on their performance, health, growth factor and some of their blood parameters. Forty-eight newborn Holstein calves were used in a completely randomized design ove...
The objective of this study was to determine the effects of different levels of garlic powder (GP) in the starter diet on performance, weight and age of weaning, some of blood metabolites, fecal score, structural growth and nutrients digestibility in new-born Holstein calves. Thirty male and femal dairy calves (40.9 ± 1.9 Kg of BW) were randomly assigned in a completely randomized design to the...
This study was carried out to determine the effects of supplementing fish oil and thyme extract on dry matter, organic matter and nutrient digestibility, chewing activity and rumen metabolites in Mahabadi goat kids. For this aim, twenty-eight Mahabadi goat kids (average initial BW of 17/8 +- 2/8 kg, 4-5mo) were randomly assigned to four treatments: 1) control (basal diet), 2) supplemented wit...
This experiment was conducted to determine the performance and intestinal microflora population of broiler chicks in diets supplemented with Roxarsone, Avilamycin and Formycin gold during starter period. A basal diet was formulated according to NRC (1994) recommendation for starter (0-21 d) period and also supplemented with appropriate amounts of the mentioned growth promoters. Each of the tr...
A 14-d broiler experiment was conducted to assess the effects of 2 dietary variables on efficacy of a bacterial 6-phytase from Citobacter braakii on nutrient and phytate P (PP) utilization. Diets were formulated with or without nutrient matrix values (matrix) for phytase as negative control (NC) or positive control (PC), respectively, and with 2 Ca:total P (tP) levels (2:1 or 2.5:1). The diets ...
studies have shown that aflatoxin is immunosuppressive and its ingestion in feed has resulted in decreased immunity in vaccinated birds .therefore, the purpose of the present study was to determine the efficacy of sodium bentonite (sb) and esterified glucomannan (e-gm) of yeast cell wall, in counteracting the toxic effects of aflatoxin (af) on immunization against infectious bursal disease (ibd...
The effect of yeast culture (Saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 Brown Bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg ME (metabolizable energy) feed. Three groups were supplemented with 3 different levels of commerci...
