To date the genus Diploplastron comprised only one species of ophryoscolecid ciliate, affine, which is characterized by having two retractable ciliary zones in anterior end body, slender and juxtaposed skeletal plates on right side, a rod shape macronucleus, contractile vacuoles. During study characterization rumen ciliate community composition Brazilian domestic sheep, we observed ciliates with atypical morphology but diagnostic features Diploplastron. This describes dehorityi, new that...

Quatro vacas lactantes canuladas no rúmen, com 155 dias em lactação, foram dispostas um quadrado latino 4 × e alimentadas, duas vezes ao dia, silagem de milho concentrado (relação 55:45, base matéria seca), para se avaliarem os efeitos da monensina do óleo soja na dieta sobre a contagem protozoários ciliados, além estabelecer correlações entre alguns parâmetros digestão fermentação ruminal. Os tratamentos consistiram inclusão 33 ppm sódica ou 4% dieta, assim representados: controle, sem -...

Haemoproteid species have a wide global distribution, and they been described in falcon several parts of the world. However, few studies South America focused on these birds. Haemoproteus spp. infections reported as causative agents serious histopathological changes, which can lead to death host. Thus, this study aimed molecularly phylogenetically characterize Caracara plancus, aspects parasitism through clinical analysis biochemical parameters, describe histopathology infection. To examine...

The species composition, prevalence, and average relative abundance of rumen ciliates were analyzed in 16 Brazilian sheep. 28 identified belonging to 3 families: Isotrichidae, Ophryoscolecidae, Parentodiniidae. Among these ciliates, Entodinium alces, Metadinium esalqum, M. rotundatum found for the first time sheep, other 12 Different morphotypes parentodiniid 7 sheep this is second report family ruminants. contractum was redescribed based on new data general morphological features; time, we...

This study aimed to determine the influence of seasonal variations on diet botanical composition and rumen protozoa five fistulated Santa Ines crossbred sheep kept in natural Caatinga vegetation pasture, Pernambuco State, Brazil. Samples were collected July 2005 January 2006, respective rainy dry seasons. Botanic animal was determined by analysis ruminal extrusa. The season composed mainly herbaceous grass species (88%), with Herissantia tiubae making up 51.7%. consisted shrub (67.4%),...

Abstract The 18S rDNA was used to infer oral ciliature patterns of evolution within the family Ophryoscolecidae, with addition five new sequences ciliates from genus Ostracodinium . Our data confirmed monophyly subfamilies Entodiniinae and Ophryoscolecinae, but more analysis would be required for definition status subfamily Diplodiniinae. infraciliature reflect evolutionary divergence in Ophryscolecidae, observing on Entodinium ‐type, Diplodinium Epidinium Ophryoscolex ‐type. ancestral ‐type...

O objetivo deste trabalho foi registrar ocorrências de predação e canibalismo em protozoários ciliados no rúmen ovinos. Foram analisadas amostras conteúdo ruminal cinco ovinos mestiços Santa Inês, fistulados rúmen, mantidos pastagem natural caatinga, município Sertânia, Pernambuco. obtidas seis cada ovino, totalizando 30 amostras, as quais foram fixadas formalina 18,5% (v/v). De amostra retirada uma alíquota 1 ml ao qual se adicionaram três gotas solução lugol para a coloração identificação...

Ten young rumen-cannulated crossbred steers were randomly divided into two groups: a control group (C; n=4), which was fed balanced diet for daily weight gain of 900g; and pronounced energy-deprived (PED; n=6), receiving 30% less the required energy maintenance. After 140 days these alimentary regimes, rumen fluid urine samples collected biochemical functional tests, before feeding at 1, 3, 6, 9 hours after feeding. The energy-deprivation caused significant reduction in number Entodinium,...

The objective of this study was to evaluate changes in ruminal protozoa lambs after partial replacement feed concentrates their diets with Gliricidia sepium silage. Twenty-four male Santa Ines an average initial weight 14.5 kg were used. experimental design completely randomized, four treatments and six replications. Treatments (given as a percentage dry matter) follows: control - corn silage (600 g kg-1 fed) + concentrate (400 fed); GS133 G. (133 kg-1as (267 GS267 (267g GS400 fed). Samples...

The genus Diplodinium includes 31 species of ophryoscolecid ciliates with two retractable ciliary zones in the anterior end body, no skeletal plates, inclined macronucleus and contractile vacuoles. They have a broad geographical distribution low host specificity. has several taxonomic inconsistencies, mainly due to polymorphism most species. anisacanthum is case inconsistency genus. It presents posterior so it considered polymorphic or seven distinct This study morphological characterization...

The genus Metadinium includes ophryoscolecid ciliates, with two retractile ciliary zones in the anterior body portion, broad skeletal plates, a lobed macronucleus and contractile vacuoles. Species belonging to this were recorded several geographical locations different host species. However, they mostly described based on single ciliatological technique, until now, there is only one description of infraciliary pattern ciliates (Metadinium medium). present study performs morphological...

The objective were to identify and quantify the rumen protozoa from two genetic groups of beef cattle (Nellore crossbred European cattle) subjected three feeding systems (pasture, pasture supplement, confined). Samples contents obtained center ruminal mass after slaughter. Quantification identification performed with a Sedgewick-Rafter counting chamber by optic microscopy. Data analyzed using general linear analysis methodology Poisson distribution (1 %). In addition, data underwent Analisys...

SUMMARY The effects of cassava wastewater on nutrient digestibility and rumen protozoa were evaluated in 32 Santa Inês sheep fed a diet with Tifton hay, ground corn cob, concentrate, containing 0, 500, 1000, or 1500 mL wastewater. Uncastrated at an average age 167 days weight 25.3 kg housed individual stalls distributed randomized complete design four treatments eight replicates. experimental period was 70 days: 15 for adaptation to the diets 60 collect ingredients supplied. Prior this...

Objetivou-se neste trabalho determinar a influência estacional sobre composição botânica da dieta e nos protozoários do rúmen de cinco ovinos mestiços Santa Inês providos fístulas ruminais mantidos em pastagens naturais vegetação Caatinga, Estado Pernambuco, Brasil. As amostras foram coletadas julho 2005 janeiro 2006, compreendendo, respectivamente, as estações chuvosa seca. A foi determinada através extrusa via fístula ruminal, que após serem analisadas indicaram durante estação espécies...

The objective of this study was to assess whether the straining rumen content samples influences estimation protozoal density. Ninety were obtained from 30 cattle (three per animal). subjected one three treatments at moment collection: 1) fixation informalin without straining(control treatment), 2) before informalin, or 3)straining after informalin.To test hypothesis variation in protozoa composition samples, multivariate analyses with non-metric multidimensional scaling (NMDS) carried out....

The aim of this study was to evaluate ruminal in situ degradability and vitro digestibility dry matter (DM) concentrate supplements containing diverse potato flour pelletized with urea (0%, 4%, 8%, 12% DM). Samples feeds were incubated for 0, 2, 4, 8, 12, 24, 36, 48h the rumen four fistulated sheep. Level added had no significant effect (P>;0.05) on soluble fraction (a) or potentially degradable (b) pellets ranged from 2.1% 12.2% 72.9% 87.5%, respectively. Quadratic effects (P=0.03) rate...
