Effects of Extrinsic Selenium Nanoparticles on the Qualitative Parameters Frozen-Thawed Sperm Broiler Breeder Roosters under Oxidative Stress Conditions

avian leukosis viruses (alvs) cause different types of tumours in poultry and can affect the health and egg production of the birds. to investigate the presence of the virus in chicken layer flocks in shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...

The aim of the present study was to evaluate the effect of zinc as feed additive on some the blood plasma traits of males and females of broiler breeder chickens. A total 132 (96 females and 36 males) of Cobb 500 broiler breeder chickens, 45 weeks old were used in this study. These birds were randomly distributed into four dietary treatment groups with three replicates each. Each treatment grou...

Campylobacter and Salmonella are known to cause acute bacterial gastroenteritis in humans. Raw poultry products have been implicated as a significant source of these infections. Five trials were conducted to determine whether Campylobacter and Salmonella spp. exist naturally in the mature and immature ovarian follicles of late-life broiler breeder hens. Broiler breeder hens ranging from 60 to 6...

mycoplasma synoviae (ms) is an important avian pathogen that can cause both respiratory disease and joint inflammation synovitis in poultry, inducing economic losses to the iranian chicken industry especially breeder farms. the aim of this study was to use the ms specific pcr and culture methods in order to detect of m. synoviae from breeder farms where located in tehran province. a total of 47...

Reoviruses are important pathogens responsible for poor growth performance and silent losses in the poultry industry. They are associated with many disease and syndromes such as malabsorption (runting and stunting syndrome), respiratory diseases and immunosuppression. Broiler birds are most susceptible to viral infections during the early post hatching period. Therefore, the transfer of materna...

the effects of chromium methionine supplementation on performance and serummetaboliteswere evaluated in broiler chickens.two experiments were conducted at22 oc, thermoneutral, (tn) and33±2 oc, heat stressed (hs) conditions. two hundred and eighty eight male broiler chicks (ross 308) were allocated to four treatments in a completely randomized design. treatments with 0 (control), 200, 400 or 800...

Trace minerals, such as Zn, Mn, and Cu, are components of eggs that are essential for broiler breeder performance as well as chicken embryo development [1, 2]. These trace minerals are constituents of several proteins involved in intermediary metabolism, hormone secretion, and the immune system [3] and are required in small amounts in the diet. The effects of Zn, Mn, and Cu deficiencies on bree...
