a eight-week trial was carried out to investigate the effects of various levels and type of organic selenium as compared to inorganic selenium. total of 81 layer hens (lsl) 35 weeks of age were used in a randomized complete blocks with 9 treatments, 3 replications of 3 birds per experimental unit. treatment diets included control 0/3 mg/kg sodium selenite and selenium yeast, (250 mg/kg, 500 mg/...

Present study was conducted to investigate the effect of organic selenium and vitamin E on physico-chemical characteristics of broiler meat. This study was a 3 x 2 factorial arrangement of three levels of organic selenium (0, 0.1, and 0.2 ppm) and two levels of vitamin-E (0 and 300mg/kg). Day-old Vencobb broiler chicks (n=180), were randomly assigned in 6 treatment groups. The experiment lasted...

The objective of this study was to determine the effect of dietary selenium source on the growth and development of turkey embryos, and egg hatchability. White broad-breasted BUT Big 6 turkeys (1800 females and 150 males) were placed under optimum management conditions. Turkey diets were supplemented with organic selenium, and in the other with inorganic selenium, in the amount of 0.3 ppm. Eggs...

BACKGROUND Selenium is part of the antioxidant defence system in animals and humans. The available selenium concentration in soil is low in many regions of the world. The purpose of this study was to evaluate the effect of organic versus inorganic selenium supplementation on selenium status of ewes, their lambs, and slaughter lambs. METHODS Ewes on four organic farms were allocated five or si...

this research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1,  0.2 and  0.3 mg/kg) on reproductive traits of rooster. semen was collected using abdominal massage and samples were mixed together. sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. this experiment was carried out based on...

the present study was conducted to evaluate the effect of different levels of organic selenium and vitamin e on performance and meat quality in japanese quail. four hundred eighty quails were carried out in a completely randomized design with two levels of organic selenium (0.2 and 0.4 mg/kg) and three levels of vitamin e (18, 90 and 180 mg/kg). four replicates with 20 quails were allocated to ...
