[ 1 ] - Effects of essential oils combination on sporulation of turkey (Meleagris gallopavo) Eimeria oocysts
Avian coccidiosis is the most important parasitic disease in poultry production, which inflicts numerous losses to the industry. The extensive use of anticoccidial drugs leads to parasite resistance and drug residue in poultry products. In the present study, we aimed to investigate the effects of three famous essential oils (EOs) and their combination on inactivation of mixed oocysts of Eimeria...
[ 2 ] - Comparative study of semen traits and histomorphometric features of testes of broiler breeder males with different phenotypic traits
Fertility reduction due to sub-fertile males is a major concern in breeder flocks. Phenotypic traits of broiler breeder males and their relationships with fertility can be used as reliable indicators for identification and removal of sub-fertile males from the breeder flocks. This study was conducted to investigate semen traits (semen volume, sperm motility, sperm viability and sperm count) and...
[ 3 ] - Spondylitis in broiler breeder farms in West-Azerbaijan province, Iran: Clinical Report
Spondylitis is a reemerging epidemic spinal infection in male broiler chickens (5 to 7 weeks of age) as well as broiler breeder roosters (15 to 18 weeks of age). Among various causative agents, Enterococcus species and in particular E. cecorum, a gram-positive bacterium as a gastrointestinal flora of birds, have mostly been isolated. On late September 2015, a number of 10 week...
[ 4 ] - Synbiotic enhances immune responses against infectious bronchitis, infectious bursal disease, Newcastle disease and avian influenza in broiler chickens
Increased susceptibility of birds to avian pathogens in intensive husbandry system has emphasized on necessity of improvement of innate and specific immune responses of birds by the fast establishment of a beneficial microflora and immune stimulator factors to guarantee healthy and low-price products. During this study, 192 one-day-old broiler chicks (Ross-380) in four groups with three replica...
[ 5 ] - Effects of Silymarin on blood parameters of broilers in an experimental chronic mycotoxicosis
Silymarin, the principal constituent of Silybum marianum, is one of the most commonlyused herbal therapies as a natural antioxidant, hepatoprotector and antihepatotoxic agent,in counteracting the toxic effects of mycotoxins. To determine the efficacy of Silymarin,the levels of hematological and serum biochemical parameters of 70 Ross broilers from35 to 49 days of age in an experimental chronic ...
[ 6 ] - Effects of nano-selenium on mRNA expression of markers for spermatogonial stem cells in the testis of broiler breeder males
Fertility is one of the most important parameters in breeder farms and cockerels play an outstanding role in fertility of eggs in broiler breeder units. Todays, supplementation of feed-additives such as organic selenium is used to increase fertility. The aim of this study was to evaluate the effects of different levels of Nano-Selenium (Nano-Se) on expression of molecular markers of spermatogon...
[ 7 ] - Efficacy of CpG-ODN Administration Routes on Humoral Responses against Newcastle disease in Broilers
Un-methylated cytosine-phosphate-guanosine oligodeoxynucleotides (CpG-ODN) has been considered as a powerful vaccine adjuvant and recognition of CpG-ODN by chicken leukocytes promotes their ability to fight against infections. In our study, efficacy of different routes of CpG-ODN application as an adjuvant on immune responses (antibody titer together with leukogram) following vaccination agains...
