A Educação a Distância (EAD) no Brasil tem suscitado intensos debates, sendo considerada ora como uma ferramenta para democratizar o acesso ao ensino, um vetor da mercantilização educação. pesquisa parte seguinte questão: EAD contribui promoção democracia e justiça social ou está subordinada aos interesses do mercado educacional Brasil? Utilizando metodologia qualitativa conforme Minayo (2016), que envolve análise documental revisão bibliográfica baseada em Gil (1999), estudo investiga dados...
ABSTRACT: This study evaluated clinical and laboratory parameters of horses treated with two different enteral electrolyte solutions administered via intracecal route. For the establishment fluid therapy, animals were submitted to a video assisted cecum cannulation. Six healthy subjected treatments under crossover design: containing maltodextrin (EESmalto) or not (EESo) as an energy source. In both treatments, was at rate 10 mL/kg/h for 12 hours. Clinical evaluations performed following time...
RESUMO Este trabalho teve como objetivo estabelecer a ocorrência de anticorpos contra neosporose, brucelose e leptospirose em alguns rebanhos bubalinos da Amazônia. Foram colhidas 212 amostras sangue búfalas, na Ilha do Marajó (n = 135) região nordeste Estado Pará 77). Examinaram-se submetidas à prova ELISA para pesquisa anti-Neospora caninum utilizando o kit (HerdeChek IDEXX Laboratories, USA); 160 soro fixação complemento (FC) anti-Brucella sp.; 205 através método soroaglutinação...
Abstract This study evaluated the effect of new or used P4 devices on ovarian responses dairy buffalo that were administered an estradiol ( E 2) plus progesterone P 4)‐based timed artificial insemination TAI ) protocol during breeding season. On first day protocol, 142 cows randomly assigned to receive one following: a device (New; 1.0 g 4; n = 48); had previously been for 9 days U sed1x, 47); 18 sed2x, 47). Ultrasound was evaluate presence corpus luteum CL ); diameter dominant follicle ØDF...
This study aimed to compare the reproductive efficiency of dairy buffaloes subjected TAI protocols based on progesterone, estrogen, and equine chorionic gonadotrophin (P4/E2+eCG) during fall/winter (n = 168) spring/summer 183). Buffaloes received an intravaginal P4 device (1.0 g) plus estradiol benzoate (EB; 2.0 mg im) at a random stage estrous cycle (D-12). Nine days later (D-3), was removed were given PGF2α (0.53 im sodium cloprostenol) eCG (400 IU im). GnRH (10 μg buserelin acetate)...
No período periparto ocorrem importantes adequações fisiológicas que, se não forem efetivas predispõem a fêmea enfermidades metabólicas. O conhecimento desta adaptação é relevante para que sejam implementadas, precocemente, medidas preventivas poupar perdas produtivas. Com este objetivo foi avaliado o perfil energético e hormonal de ovelhas Santa Inês durante gestação puerpério. Foram utilizadas 10 gestantes (G0), um (G1) 14 dois três fetos (G2). avaliadas concentrações plasmáticas glicose,...
The purpose of this study was to establish normal reference electrocardiographic (ECG) values for standard limb lead II in Saanen goats. For this, were used 19 healthy adult female And the ECG parameters, 95% confidence level. overall P, Q, R, S and T durations (seconds) 0.03±0.01, 0.02±0.005, 0.03±0.014, 0.03±0.011, 0.06±0.014 respectively, 0.01-0.04, 0.01-0.02, 0.01-0.06, 0.02-0.04 0.04-0.08 respectively. amplitudes (milivolts) these waveforms 0.1±0.031, 0.06±0.023, 0.44±0.312, 0.39±0.434,...
Metabolic adaptations to negative energy balance, as well lipomobilization, influence inflammatory responses, immune function, and oxidative stress in animals. This study aimed evaluate the biochemical profile of Mediterranean buffaloes with different levels lipomobilization from prepartum postpartum period. A total 76 were enrolled, a weekly blood sample was taken 7 weeks before 6 after calving. The concentration non-esterified fatty acids (NEFAs) determined serum used categorize into three...
Objetivou-se com este trabalho descrever as medidas biométricas de cordeiros lactantes da raça Santa Inês criados em condições amazônicas; estabelecer relação entre a idade e corporais; bem como correlacionar essas o peso corporal. Utilizaram-se 75 animais sistema semi-intensivo, submetidos mensurações do corporal (PC), comprimento (CC), altura anterior (AA) posterior (AP), perímetro torácico (PT), largura garupa (LG) peito (LP), perna (CP), (PP) compacidade (COMPC), ao nascer aos 15, 30, 45...
ABSTRACT Serum blood samples from 50 Murrah buffalo calves were examined in this study. The animals allocated into three groups according to the number of parturitions their mothers: G1 (n= 15) primiparous buffaloes, G2 19) buffaloes with two four parturitions, and G3 16) five or more parturitions. Blood taken at birth, before colostrum ingestion, 24h, 48h, 72h after 7, 14, 21, 30 days birth for determination levels gammaglutamyl transferase (GGT), alkaline phosphatase (ALP), aspartate...
Abstract Background Bovine tuberculosis (bTB), is a worldwide disease caused by Mycobacterium bovis ( M. ). The success of bTB eradication and control programs based on early detection the removal reactors from herd thus routine testing cull strategy have been applied globally. Since late nineteenth century, Tuberculin Skin Test (TST) has primary antemortem test available to support campaigns. Due TST limitations in terms Se Sp, credibility diagnosis frequently questioned given occurrence...
