Industrial egg residue as a calcium source in broiler feed: digestibility and growth performance.

Industrial egg residue (IER) possesses substantial concentrations of calcium and crude protein. The objective of this study was to measure the digestibility and performance of broilers when IER was added to the feed. Four treatments were tested, which caused increasing replacement of calcitic limestone by IER (0, 35, 70 and 100%) during a 42-day production cycle.

Experimental infection with Escherichia coli in broilers: Impacts of the disease and benefits of preventive consumption of a stimulator of homeopathic immunity.

Colibacillosis is a disease caused by Escherichia coli that manifests itself when there are homeostatic imbalances or in the context of increased exposure, in which case the organism displays opportunistic behavior. To control this problem in poultry, antibiotics are used in the feed, because E. coli is component of the intestinal microbiota of birds.

Impact of Escherichia coli infection in broiler breeder chicks: The effect of oxidative stress on weight gain.

The aim of this study was to determine whether oxidative stress occurs in Escherichia coli-infected broiler breeder chicks, as well as the impact of this infection on bird growth. Twenty birds, 25-day-old female birds were divided into two groups (n = 10 per group): an intraperitoneally-infected group (1 mL containing 1.5 × 10 CFU of E.

Impacts of Escherichia coli infection in young breeder chicks on the animal behavior and cerebral activity of purinergic and cholinergic enzymes involved in the regulation of molecules with neurotransmitter and neuromodulator function.

The objective of this study was to evaluate if infection by Escherichia coli in juvenile breeder chicks alters the activity of enzymes involved in neurotransmission and cerebral immunomodulation, including acetylcholinesterase (AChE), nucleoside triphosphate diphosphohydrolase (NTPDase), 5'-nucleotidase (5'NT) and adenosine deaminase (ADA), as well as their effects on the pathogenesis of the disease. We divided 20 growing breeder chicks into two groups (n = 10 per group). One group was experimentally infected with 1 mL of culture medium containing 1 × 10 CFU of E.

Difficulties in the diagnosis and treatment of rare diseases according to the perceptions of patients, relatives and health care professionals.

Objectives: The aim of this study is to present a survey of vulnerabilities and to suggest approaches for the treatment of rare diseases according to the perceptions of a group of affected individuals, patient association representatives and health care professionals.

Methods: The focus group technique was used in interviews with patients and primary caregivers, patient support groups/non-governmental organizations, primary health care professionals and physician specialists.

Results: The transcript analysis focused on thematic units, which were tailored to each group and allowed comparisons in search of concordant views.

Reliability of the Brazilian version of the PedsQL - ESDR questionnaire to evaluate quality of life of children and adolescents.

Objective: To evaluate the reliability of the translation and cultural adaptation of the Pediatric Quality of Life Inventory (PedsQLTM) - End Stage Renal Disease (ESRD) - version 3.0 - children/adolescents and parents reports in Brazilian children with ESRD.

Methods: A group of 24 children and adolescents with ESRD, followed at Unidade de Nefrologia Pediátrica do Instituto da Criança - HCFMUSP and 32 primary caregivers were interviewed according to the me methodology proposed by the creator of the original questionnaire.
