This work aimed to study the possible relationships among magnitude of abomasal worm burden and proliferation globular leucocytes mucosal mast cells in mucosa, white blood cell count. Eighteen Suffolk × Greyface lambs were infected with Haemonchus contortus, 12 kept free nematodes. Blood samples collected on days 0, 30, 57 post-infection (p.i.) for leucogram determination. At day 62, all animals euthanized count total number nematodes recovered abomasum leucocytes. On 57, higher levels...
The aim of this study was to evaluate the effects selenium and copper on oxidative stress its performance in lambs experimentally infected with Haemonchus contortus. Twenty-eight five-months old were by oral route 5000 third-stage infective larvae allocated into four groups, i.e., untreated animals, animals treated intramuscularly sodium selenite (0.2 mg kg(-1)), subcutaneously (3.5 (IM; 0.2 kg(-1)) (SC; 3.5 kg(-1)). These received oat hay (Avena sativa) commercial concentrate, totaling 15%...
SUMMARY The aim of this study was to evaluate the purine levels lambs experimentally infected with Haemonchus contortus . A total 12 healthy were divided into two groups, composed 6 animals each: Group represented (uninfected), while in B 15 000 larvae H. Blood drawn on days 15, 45 and 75 post-infection (PI) order perform analysis (ATP, ADP, AMP, adenosine, inosine, hypoxanthine, xanthine uric acid) by high pressure liquid chromatography (HPLC) serum. On day PI a significant ( P <0·05)...
SUMMARY The cowside determination of blood β-hydroxybutyrate (BHB) is an important tool for diagnosing subclinical ketosis in dairy cattle. Portable methods to measure BHB have been introduced the past years. This study evaluated accuracy two hand-held electronic devices cows at early postpartum. A total 98 samples were collected from first month lactation and tested with FreeStyle Optium (FSO, Abbott) KetoVet (KVE, TaiDoc) portable according manufacturer instructions. Spectrophotometric...
ABSTRACT: To evaluate the effect of supplementation iron dextran on blood variables and metabolism in lambs experimentally infected by Haemonchus contortus, four experimental groups were used: uninfected non-supplemented animals (GI); supplemented with (GII); (GIII); (GIV). Groups II IV received 10,000 larvae (L3) III three doses (20mg/kg) intramuscularly seven days interval. Blood faeces samples collected 10 (D10), 17 (D17), 24 (D24), 31 (D31), order to determine red cell counts,...
ABSTRACT The aim of the present study was to report in vivo distribution selenium sheep. For this, animals were allocated into two groups (control group and treated group) kept metabolic cages for a period 37 days. received single dose (6µmol/kg) Diphenyl Diselenide, intravenously. Plasma erythrocytes samples collected at different times. Adipose tissue, muscles (latissimusdorsi, semitendinosus, supra-scapular) heart, liver, lung, kidney, intestine brain sampled 30 days post-treatment, order...
Foram realizados dois experimentos para determinar os efeitos tóxicos de diferentes doses aflatoxinas em bezerros, considerando-se aspectos clínicos, produtivos e patológicos. No primeiro experimento, nove Holandês, com 2-4 meses idade, receberam ração contendo 500±100 ppb aflatoxina, na quantidade equivalente a 1,5% do peso vivo/dia, durante meses. Três bezerros idade semelhantes foram usados como controle e, exceto por terem recebido livre aflatoxinas, mantidos nas mesmas condições....
The aim of this study was to evaluate a new source injectable organic zinc (zinc edetate) on the energy and oxidative profile in sheep during immediate postpartum period. Twenty-six Texel breed animals were previously identified divided into two experimental groups: treated group (TG; n= 13) that comprised received subcutaneous (SC) injection 100 mg edetate (2 mL) fifteen days before parturition expected date control (CG; n=13) 2mL physiological solution at same TG. Blood samples collected...
RESUMO Avaliou-se o efeito da suplementação com colina protegida sobre perfil energético, as enzimas hepáticas e a reprodução de vacas leiteiras no periparto. Quinze foram divididas em dois grupos experimentais: oito receberam 80 gramas por 21 dias pré-parto 40 pós-parto sete consideradas controle. Amostras sangue coletadas nos 10, 20, 30 60 para avaliação dos perfis energético hepático. Aos pós-parto, realizou-se exame ginecológico animais saúde reprodutiva. A não alterou os níveis...
RESUMO Durante o periparto, as vacas leiteiras são submetidas a uma grande demanda de energia, ao mesmo tempo em que reduzem sua ingestão matéria seca. O balanço energético negativo, resultante dessa equação, acarreta severos transtornos metabólicos, à produção e, principalmente, reprodução. objetivo do presente estudo foi avaliar efeito da colina protegida sobre os parâmetros intervalo entre parto e concepção leite no período transição. Cinquenta quatro foram divididas três grupos:...
