Avian salmonellosis is a worldwide problem to the poultry industry, from the point of view of animal health and public health as well. The aim of the present study was to survey the most common Salmonella serovars in commercial breeders or broiler flocks from several regions in Brazil. The results of the present study indicated a high incidence of S enterica subspecies enterica serovar Enteriti...

Genetic improvement of pig performance was summarised for 28 Australian pig populations at the previous AGBU pig genetics workshop (Hermesch, 2006). The average genetic trend was $1.06 per pig each year. In comparison, the top 25% of populations had achieved $1.92 per pig each year. During subsequent discussions at the workshop, breeders set a target of an annual genetic gain of $3 per pig. In ...

The social mole-rats of the family Bathyergidae show elaborate organisation that may include division labour between breeders and non-breeders as well across within their groups. However, comparative behavioural data taxa are rare contrasts similarities species poorly understood. Field studies bathyergids usually involve capturing all group members until entire is captured. Because each animal ...

Artificial insemination (AI) and embryo transfer (ET) are not just reproductive techniques, but indispensable tools for genetic improvement. In this sense, they play an effective part in propagating improved breeds. Analysis of the development of insemination of French cattle breeds since 1960 shows how breeders can alter their genetic choices to meet economic needs. AI and ET also have their p...

the aim of this study was to investigate the role of livestock cooperatives in improving economic status of animal holders in hamedan province. the study has used a surveying methodology. for gathering data a structured questionnaire was used and its reliability was calculated by cronbach's alpha test and it was (α=0.80). the research samples consisted of 300 animal holders (beef cattle breeder...

The maintenance of the endangered Caspian brown trout Salmo trutta caspius populations in Iran depends on its artificial breeding. There is no information on how current hatchery breeding protocol influences effective population size of breeders (Ne), which is a critical parameter to maintain genetic diversity in future generations. The current hatchery protocol (CHP) was comparatively evaluate...
