Feed intake is the major factor that influences both the body weight gain and feed efficiency in meat-type poultry. Because so many factors can influence feed intake, it is often difficult to correct a problem of poor feed intake unless a complete review of feed and management practices is made. Management and flock health issues are usually more likely to reduce feed intake than dietary factor...

Mortality due to strongyles infection in small ruminants is a critical component of flock productivity in a tropical climate. In goat production, few experiments have been conducted to estimate the variability of this trait. A survival analysis study was carried out in the Creole experimental flock of INRA-Gardel (Moule, Guadeloupe) to identify management and genetic factors influencing mortali...

BACKGROUND Serum samples from 630 milk sheep, in 33 dairy flocks representative of the southern area of the Tuscany region, were tested for the presence of antibodies to Toxoplasma gondii using an indirect immunofluorescence antibody test (IFAT). Questionnaires exploring the management system were completed by the veterinarian in charge of the flocks. RESULTS At least one seropositive animal ...

We conducted an observational study to estimate prevalence and risk factors for Salmonella spp. and Campylobacter spp. caecal colonization in poultry. Eighty-one broiler chicken and 59 turkey flocks selected among flocks slaughtered in the province of Quebec, Canada, were included in the study. Flock status was evaluated by culturing pooled caecal contents from about 30 birds per flock. Exposur...

A cross-sectional study based on planned sampling was carried out to determine flock-level risk factors associated with Toxoplasma gondii antibody prevalence in dairy goat flocks in a semiarid region of northeastern Brazil. Serum samples from 975 adult dairy goats from 110 flocks were examined by indirect immonufluorescent antibody test (IFAT), using cut-off point at 1:64 dilution. From the 110...

Maedi-Visna (MV) is a chronic progressive multisystem disease that may be asymptomatic for several months or years, but progress rapidly, and result in death, when signs symptoms evolve. Viral elimination occurs mainly through direct contact with positive animal secretions. There no vaccine treatment, prophylaxis necessary the health of herd. The present study aimed to verify seropositivity MV ...

Background: Improving the knowledge of healthcare providers towards different aspects of breast cancer leads to appropriate management and screening of disease. This study aimed to investigate the knowledge of breast cancer risk factors among a cohort of nurses in Iran. Materials and Methods: The target group of the present study was 243 consecutive nurses (27 males and 216 females) at two re...

1. Feather pecking is one of the major problems facing the egg industry in non-cage systems and is set to become even more of an issue with the European Union ban on the keeping of laying hens in barren battery cages which comes into force in 2012 and the prospect of a ban on beak-trimming. Reducing feather pecking without resorting to beak treatment is an important goal for the poultry industr...
