Anticoccidial efficacy of drinking water soluble diclazuril in the control of Eimeria acervulina oocysts on experimentally-infected broiler chickens Arq. Bras. Med. Vet. Zootec.
Assis,R.C.L.; Cury,M.C.; Luns,F.D.; Assis,R.L..
The experiment was carried out with 150 Cobb broiler chickens divided into 3 groups with 50 birds each. The groups of infected chickens orally received 1ml of inoculum containing 3x103 Eimeria acervulina sporulated oocysts at 12 days of age. Group 1 was kept as a positive control with infected non-medicated birds, group 2 was medicated with diclazuril (1%) with a dose of 1mL/4 L of drinking water for 2 successive days, 5 days after infection, while group 3 was kept as negative control with non-infected and non-medicated birds. Oocysts count per gram of feces, score of macroscopic intestinal lesions and weight gain were evaluated. The group treated with diclazuril showed significant and satisfactory improvement in the assessment criteria when compared to...

Coccidiosis and performance in broilers with anticoccidial medicated feed starting at different ages Arq. Bras. Med. Vet. Zootec.
Costa,C.A.F.; Guidoni,A.L.; Paiva,D.P.; Ávila,V.S..
The effects of age, litter reutilization, and anticoccidial programs were studied in broilers. The oocyst counts increased with litter reutilization up to third use, and T1 (no anticoccidial drug over the entire 42-day-period) and T4 (anticoccidial medication starting from the first day) showed the highest counts. The scores for Eimeria acervulina increased up to third use of litter and declined by the fourth use. The scores for E. maxima increased from first to second litter use, and from this to third and fourth use. The scores for E. tenella increased from first and second litter use to third litter use, and declined on fourth use. With high coccidial contamination, as in third use litter, the anticoccidial medication starting from the 1st, 7th (T3) and...

Coccidiosis in japanese quails (Coturnix japonica): characterization of a naturally occurring infection in a commercial rearing farm Rev. Bras. Ciênc. Avic.
Teixeira,M; Teixeira Filho,WL; Lopes,CWG.
A study about coccidiosis in Japanese quails was carried out in order to identify species of the genus Eimeria and characterize a naturally occurring infection in a commercial rearing farm. For this purpose, fecal exams, oocyst counting and morphological study were performed, besides necropsy and histopathology to confirm diagnosis. Three species of the genus Eimeria were found and identified as E. tsunodai, E. uzura and E. bateri. The natural infection was characterized as subclinical because of the mild and nonspecific clinical signs. Nevertheless, coccidiosis was considered an important disease because endogenous stages of the parasites and a high number of oocysts in feces were associated with intestinal lesions. The results suggest that such infection...

Dexamethasone Regulates Macrophage and Cd4+Cd25+ Cell Numbers in the Chicken Spleen Rev. Bras. Ciênc. Avic.
Calefi,AS; Quinteiro-Filho,WM; Fukushima,AR; Cruz,DSG da; Siqueira,A de; Salvagni,FA; Namazu,LB; Gomes,COMS; Ferreira,AJP; Palermo Neto,J.
Abstract Dexamethasone (DEX) is a corticoid hormone that is experimentally used to mimic the effects of increased levels of endogenous corticosterone observed during the stress response. Currently, stress is considered one of the major predisposing factors for diseases in the poultry industry. The aim of this study was to analyze the effects of DEX and/or of a 20-fold coccidial vaccine dose on leukocyte phenotypes in the spleen and cecal tonsils of chickens. Twenty specific-pathogen-free (SPF) Leghorn chickens were divided into four groups: a non-treated group (NT), a DEX-treated group (Dex), a vaccinated group (V) and a DEX-treated+vaccinated group (Dex+V). On experimental day (ED) 42, each bird in the vaccinated groups received a anti-coccidial vaccine....

Effect of vitamin E levels on the cell-mediated immunity of broilers vaccinated against coccidiosis Rev. Bras. Ciênc. Avic.
Silva,ICM da; Ribeiro,AML; Canal,CW; Vieira,MM; Pinheiro,CC; Gonçalves,T; de Moraes,ML; Ledur,VS.
Studies on the relationships between animal nutrition and immunity have sought reliable methodologies to measure responses. Cell-mediated immune response is similarly studied in humans. The cutaneous basophil hypersensitivity test (CBH) is one of the methods to measure that response and consists in the infiltration of inflammatory cells, particularly of lymphocytes and basophils, as result of the application of substances capable of inducing cell proliferation in determined sites, such as wings, wattle, and interdigital space in birds. CBH is considered a simple and fast method and can be applied in birds of different ages. In immunocompetence studies with poultry, phytohemagglutinin-P (PHA-P) is a commonly used substance, despite the variability of the...

Effects of an Ionophore Coccidiostat (Monensin or Salinomycin), Sodium or Potassium Bicarbonate, or Both, and Bacitracin Methylene Disalicylate in Broiler Chicken Diets Rev. Bras. Ciênc. Avic.
Hooge,DM; Cummings,KR; McNaughton,JL.
Peterson x Arbor Acres chicks were grown on used litter to 45 or 46 days of age in three pen trials. Coccidial inoculations were given by water at 14 days of age. Sodium bicarbonate (SBC; 0.20%) or potassium bicarbonate (PBC; 0.14%) was added to broiler chicken diets containing monensin (MON; 110 mg/kg) or salinomycin (SAL; 66 mg/kg) in Experiment 1. In Experiment 2, using SAL (55 mg/kg), three dietary bicarbonate treatments (SBC, 0.20%; PBC, 0.20%; or SBC + PBC 0.10% each) were tested with or without BMD R (55 mg/kg). Diets differing in SAL, BMD R, and SBC levels were evaluated in Experiment 3. Beneficial interaction was found between ionophores and bicarbonates for mortality (lower when SBC or PBC and MON) in Experiment 1. For main effects, in Experiment...

Incidence of coccidiosis in different rabbit keeping systems Arq. Bras. Med. Vet. Zootec.
González-Redondo,P.; Finzi,A.; Negretti,P.; Micci,M..
Amostras fecais de coelhos foram examinadas pela técnica de flutuação para a presença e contagem de oocistos do gênero Eimeria, de acordo com a técnica McMaster, em uma investigação com o objetivo de comparar um sistema alternativo não medicamentoso de criação de coelhos e sistemas convencionais com diferentes níveis de controle higiênico. A presença de oocistos nas diferentes explorações foi baixa, mas muito variável. As maiores concentrações de oocistos foram encontradas nas explorações cujas condições higiênicas não foram boas, independentemente do tratamento ou não com anticoccidiano, ou do sistema de criação. Os melhores resultados foram observados no sistema alternativo com boas condições higiênicas. Neste sistema, a concentração de oocistos nos...

LAYERS '99, PART I: REFERENCE OF 1999 TABLE EGG LAYER MANAGEMENT IN THE U.S. AgEcon
The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS:Veterinary Services (VS). The NAHMS Layers '99 Study was designed to provide information about the nation's layer population for education and research purposes. The USDA's National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically-valid sample from 15 states for Layers '99. The 15-state target population accounted for over three-quarters of the table egg layers in the U.S. as of December 1, 1998. The study was limited to companies with 30,000 or more layers. While the majority of farm sites were contract farms (61.0 percent), the majority of birds were located on company owned farms (72.6 percent), indicating that company owned farms...

Ribeiro,A.D.B.; Ferraz Junior,M.V.C.; Polizel,D.M.; Miszura,A.A.; Gobato,L.G.M.; Barroso,J.P.R.; Susin,I.; Pires,A.V..
ABSTRACT Two experiments were conducted to evaluate the effect of thyme (Thymus vulgaris) essential oil (EO) doses on rumen fermentation, nutrient digestibility, and nitrogen metabolism, as well as performance and coccidia oocyst discharge. In experiment I, 20 rumen-cannulated wethers received the experimental diets containing 80% dry matter (DM) of haylage and 20% DM of concentrate. Treatments were 25mg of monensin/kg DM or doses of 1.25, 2.50, or 3.75g of thyme EO/kg DM. In experiment II, 50 ewe lambs received the same diets from experiment I, including a diet without feed additives. Wethers fed with diets containing 1.25g/kg DM of thyme EO had higher molar proportion of propionate (P= 0.03) and butyrate (P< 0.01), and lower (P= 0.04) acetate to...
