Along with the prevalence of abortion services, the development of methods of early medical (nonsurgical) abortion has the potential to affect the availability and utilization of these services. By 1995, mifepristone, in combination with a prostaglandin, was offered on a limited basis under experimental protocols up to 63 days from the woman’s last menstrual period; however, this method has not...
Dietary restriction (DR) has been shown to extend both median and maximum lifespan in a range of animals, although recent findings suggest that these effects are not universally enjoyed across all animals. In particular, the lifespan effect following DR in mice is highly strain-specific and there is little current evidence that DR induces a positive effect on all-cause mortality in non-human pr...
State wildlife agencies have translocated thousands of wild turkeys (Meleagris gallopavo) since the 1930s to reestablish this species. Because of threats to the domestic poultry industry and wild birds, screening for selected infectious agents has become routine since the early 1980s. One of the principal sources for Rio Grande wild turkeys (M. gallopavo intermedia) for translocation purposes w...
The goal of this research was to determine the extent of anthelmintic resistance that turkey roundworms, Ascaridia dissimilis, have developed to anti-parasitic chemicals used in commercial turkey operations. Roundworm infections in turkeys have resulted in monetary losses for the poultry industry for years, due to poor feed conversion. The infection itself is generally subclinical and many turk...
Since the first outbreak of avian influenza (AI) in Nigeria in 2006, there has been continuous monitoring of the disease in chickens with little attention given to turkeys. As part of on-going surveillance for AI in southwest Nigeria, we used a competitive ELISA to detect anti-AI virus antibodies in 520 turkey sera obtained from poultry farms in Oyo, Osun, and Ondo states while haemagglutinatio...
A study was conducted to determine the clinical effects of 2% ractopamine hydrochloride (RAC) Type A Medicated Article on growth performance in tom finishing turkeys (576, Nicholas, Large White) during 3 different age periods: 15–17, 17–19, and 19–21 wks of age. After a one week acclimation period, turkey finisher toms were fed one of 2 treatments with and without RAC (4.6 g/ton) for the last 1...
Domestic turkeys present several color phenotypes controlled by at least five genetic loci, but only one of these has been identified precisely: the bronze locus, which turned out to be the melanocortin-1 receptor (MC1R) gene. MC1R variation is important for breeders interested in maintaining or developing different color varieties. In this study, we sequenced most of the MC1R gene from 16 Whit...
The intensification of turkey farming is accompanied by the impact various dangerous factors on poultry’s body. This leads to a violation metabolic processes, an imbalance in absorption nutrients, and immunity decrease turkeys, which determines relevance study this area. In regard, figuring out when reduces and, future, increasing its effectiveness body improving growth, development poultry det...
The purpose of the research is to test efficacy different concentrations composite Kenocox against Eimeria spp. oocysts in turkeys a laboratory experiment and under production conditions. Materials methods . anti-Eimeria activity new disinfection agent was tested as compared with phenol two stages. first stage used 2, 4 6% 4% base drug. second bioassay artificial infection young turkeys, conduc...
Sera from 173 turkeys, 108 chickens, and 48 ducks from Giza, Egypt, were tested for the presence of anti-Toxoplasma gondii antibodies by means of the modified agglutination test using mercaptoethanol and formalin-fixed tachyzoites. The prevalence of anti-T. gondii antibodies (>1:25) among turkeys, chickens, and ducks was 59.5%, 47.2%, and 50%, respectively.
