| Avaliou-se a sensibilidade antimicrobiana in vitro de 121 cepas de estafilococos coagulase-negativa isolada de leite de ovelhas Santa Inês, aos fármacos: penicilina, amoxicilina, ampicilina, estreptomicina, oxaciclina, neomicina, cefalotina, gentamicina e sulfonamida. A resistência à sulfonamida foi a mais frequente (27,3%), seguida pela estreptomicina (14,0%) e pela oxaciclina (14,0%), enquanto da gentamicina (1,6%) foi a menos frequente. Todas as cepas foram sensíveis a pelo menos um antimicrobiano, e 20,3% das cepas apresentaram resistência múltipla. Os resultados mostram a importância de Staphylococci coagulase-negativas como agentes causadores de mastite em ovinos, e o perfil de resistência múltipla indica a importância da determinação da resistência... |

| To rear lambs of the Ojalada breed, fed exclusively on mothers' milk until 5 weeks, three feeding systems were compared: a) ewes kept indoors and fed chopped straw plus concentrate (IND+CH+C), total mixed ration (TMR); b) ewes kept indoors and fed whole straw in the form of large bales plus concentrate (IND+W+C), TMR; and c) free-range grazing plus concentrate (GR+C; control group). Parameters related to ruminal fermentation (pH, NH3-N concentration and proportion of volatile fatty acids (VFAs)) in 40 sheep during a production cycle were monitored. The plasma concentrations of stress-related metabolites (i.e., glucose, lactate, phosphate, creatine kinase (CK), cortisol and non-esterified fatty acids (NEFAs)) during a production cycle and in 10 sheep during... |

| Our study shows an analysis of a sheep farm. The present farm was chosen for analysis due to the fact that it is run under special natural conditions and as for the sheep farming, it has quite a few non-typical features. These raise some economic issues, which have to be analysed, questions have to be answered that may result in useful conclusions. Since sheep farming does not seem to be able to overcome its difficulties on its own, the EU support system could give the initial step necessary for the success and would also help to sustain sheep farms. The amount of grant that is usual in the EU could provide for the sustainability of this sector, the relative safety of sales, the equal chances of the farms operating under different capabilities and if... |

| ABSTRACT: Pregnancy diagnosis is an important tool for farm management. Ultrasonography is the main technique used for pregnancy diagnosis in ewes. As an alternative, radioimmunoassay (RIA) allows accurate and early detection of pregnancy-associated glycoproteins (PAGs) in sheep blood. However, radioactive-based techniques, as RIA, have been increasingly inadvisable due to environmental risk. Homology between ovine and bovine PAGs is high, and ELISA kits used for PAGs detection in cattle are safer than RIA. Thus, this study aimed to evaluate the feasibility of PAGs detection for pregnancy diagnosis in sheep serum samples using an ELISA kit produced for cattle. The sensitivity and specificity of the ELISA kit were 93.5% and 98.9%, respectively, whereas... |

| The aim of this trial was to evaluate the effect of dietary supplementation of extruded linseed on the milk and cheese fatty acid (FA) profiles of ewes under extensive grazing conditions. Over 26 days, a group of nine lactating ewes (Latxa × Milchschaf × Corriedale) in mid-lactation were managed under grazing conditions and given supplements during each manual milking (0830 and 1800 h) of 50% corn and 50% oats (500 g ewe-1 milking-1; control, TC) for the first 6 days. From day 7 to 20, the supplement was 25% corn, 25% oats and 50% extruded linseed (500 g ewe-1 milking-1) (extruded linseed; TEL). From day 21 to 26, the ewes were fed TC. The saturated FA content in milk was reduced (3.6%), and the monounsaturated, polyunsaturated and n-3 FA (7, 10 and 25%,... |

| Hematological and biochemical parameters, including plasma electrolytes and thyroid hormones, were determined in 73 clinically healthy Churra-da-Terra-Quente ewes, a typical breed from the northeast of Portugal. The hemogram values were: erythrocytes 9.8±1.5×10(12)/L; haemoglobin 118.1±19.1g/L; haematocrit 40.8±5.9%; leukocytes 5.7±1.8×10(9)/L; and platelets 544.3±177.2×10(9)/L. The thrombin time was 17.3±1.7 seconds. The values of biochemical parameters were: total protein 76.4±6.1g/L; glucose 2.87±0.60mmol/L; total cholesterol 1.65±0.33mmol/L; aspartate aminotransferase 155.9±49.2U/L; alanine aminotransferase 23.2±9.6U/L; γ-glutamyl transferase 48.0±18.7U/L; total alkaline phosphatase 121.6±76.1U/L; glutamate dehydrogenase 6.4±3.7U/L; urea... |

| The histological changes of the liver in ewes with pregnancy toxemia were characterized. Ten ewes were fed on grass ad libitum, and another ten were starved from day 130 of pregnancy for up to four days. Liver puncture biopsies were performed at days 70, 100, 130, and 140 of pregnancy, and at day 45 in postpartum. Seric hydroxybutyrate (HB), non-esterified fatty acids (NEFA), aspartate aminotransferase, and alkaline phosphatase were dosed. Histological preparations revealed similar incidence and intensity of mild liver steatosis in both groups at day 130. Starved ewes become toxemic (as indicated by HB), and at day 140 exhibited more severe injury in a higher proportion (9/9 vs. 4/10; P<0.01). Almost all of them (7/9) had large amounts of small lipid... |

| Avaliou-se o risco de infecção em diferentes fases da lactação em 33 ovelhas da raça Santa Inês. Inicialmente a glândula foi submetida ao exame físico e à prova de fundo escuro. Posteriormente, amostras de leite foram coletadas assepticamente para a realização de exame bacteriológico - California Mastitis teste -, e contagens microscópica e automática de células somáticas. Nenhuma diferença foi observada entre as distintas fases de lactação. Observou-se alta persistência de infecções intramamárias, e tendência a maior contagem de células somáticas no último período de lactação, que pode ser oriunda da maior resistência a infecções neste período. |

| The use of synthetic progestagens released by vaginal devices is an important tool to overcome the reproductive seasonality in sheep, but cost and/or subsequent vaginitis are limiting factors for their use. To identify economic, simple and innocuous alternative vaginal devices for estrous synchronization/induction protocols in sheep, this study aimed to evaluate the microbiological and functional viability of the human vaginal tampons (OB®) impregnated with medroxyprogesterone acetate (MAP) on reproductive performance of ewes. The study compared them with commercial vaginal inserts (CIDR®) and polyurethane sponges impregnated with MAP. In Experiment 1, the device loss rate, the degree of vaginitis during the device removal, the count and identification of... |

| ABSTRACT The objective of this study was to determine the effect of supplemented organic selenium at different levels to concentrate feed of Norduz ewes in late pregnancy on maternal serum, placenta, colostrum, and offspring serum concentrations. This study was conducted using two-year-old 35 Norduz ewes. Ewes were randomly assigned to one of three dietary treatments for 57 days prepartum and at the seven days postpartum. Group 1 was fed a standard pregnant sheep concentrate basal diet without any additional Se supplement (control). Experiment groups were fed diets supplemented with 0.150 mg/kg, 0.300 mg/kg, and 0.450 mg/kg organic selenium to the same basal diet. Results showed that addition of selenium to gestating ewe diets increased Se in serum after... |
