| SUMMARY Ovine mastitis causes varying economic fosses in all countries where sheep are kept. A survey of 3128 breeding ewes in 22 farms in two areas with different management practices in Southern Brazil showed that the average prevalence of subclinical and chronic mastitis was 14.1% of ewes with at least one affected gland. From those, 4.49% were also bacteriologically positive. The prevalence in individual farms varied from 0 to 37% of ewes with clinical abnormalities of the udder. The overall prevalence was greater in Area II, where meat breeds predominate and animals are housed at night. It is concluded that subclinical and chronic mastitis is uniikely to be an economic problem in Area I, where wool production is the objective of the sheep industry.... |

| ABSTRACT The objective of this study was to analyze the factors that influence the performance of lambs in pasture confinement, by substituting a concentrate with different levels of the aerial part of cassava in relation to hematocrit indices. The experiment was conducted at the Sheep Technology Center using 56 Pantaneira sheep, of which 28 were male and 28 were female. For female lambs, the globular volume showed a decreasing quadratic effect, with a minimum inclusion of 10.24% PAM in the diet for a hematocrit index of 32.28. A linear effect was observed for the mean crude protein intake in the male lambs based on the diet provided and was estimated to be equivalent to 87.4% of the lambs’ final weight. In conclusion, mean crude protein consumption is... |

| ABSTRACT: This study examined the characteristics of the fatty acids profile in the meat of lambs fed grazing and supplemented with different PUFA sources. Thirty Suffolk lambs were used (37.2±5.4kg BW), grazing on perennial ryegrass (Lolium perenne) (12h d-1) and supplemented (30g kg-1 BW0.75) with ryegrass hay (RGH), or supplements formulated with fishmeal (FHM) or soybean meal (SBM). Lambs were used in a completely randomized design. Results showed an effect on total SFA, with SBM higher than RGH (P=0.033), and SBM and FHM showing higher MUFA content compared with RGH (P=0.001). Total PUFA content was higher for RGH, followed by FHM and with the lowest content for SBM (P=0.001). Concluding that there is a variation in fatty acid content depending on the... |

| Twenty seven (48.2%) culture supernatants of 56 Escherichia coli isolated from diarrheic lamb feces (7 to 10 days old) in São Paulo State, Brazil, presented positive results to suckling mice assay (fluid accumulation) but none caused cytopathic effects on Vero and CHO cells, indicating that these strains did not produced LT or VT toxins. PCR assays showed that these 27 E. coli strains harbored estA, that codifies for STa, but not for stx1, stx2 or cnf genes. The positive STa strains were checked for genes that codify for F41, F17 and K99 fimbriae, wich are considered colonization factors in ETEC. Only F17 was detect in two samples (7.4%). Twelve of 27 STa positive carried hlyA gene and presented hemolytic activity in blood Agar. Presence of rotavirus was... |

| Los altos niveles de ácidos grasos saturados en la carne de rumiantes representan un punto crítico en la alimentación humana por su relación con enfermedades cardiovasculares. La levadura Saccharomyces cerevisiae (Sc) es rica en ácido oleico y representa una alternativa para modificar el perfil de ácidos grasos de la carne, al incrementar la proporción de ácidos grasos insaturados. Por lo anterior, se realizó un experimento con corderos en crecimiento (20± 0.9 kg PV), utilizando una dieta a base de concentrado y tres niveles (tratamientos, T) de Sc (0, 3 y 5 g animal-1 d-1, T1, T2 y T3, respectivamente), con el objetivo de determinar el comportamiento animal, caracterizar la fermentación ruminal, los niveles plasmáticos de colesterol y los ácidos grasos... |

| This work was carried out in order to generate information on the tillering process and to contribute for the understanding of the defoliation process on Italian ryegrass (Lolium multiflorum Lam.) grazed by lambs under different herbage allowances: 6, 8 and12 kg of dry matter per100 kg of animal live weight per day. The grazing method was intermittent. The experimental design was completely randomized following a repeated measure arrangement, with three treatments and two area replications. The intensity of defoliation is greater at 6 and 9% herbage allowances. The defoliation interval is higher at 12% herbage allowance, intermediate at 9% and lower at 6%. The rates of tiller emergence, survival and death, stability index the tiller population are... |

| The feeding and the shelter are considered basic needs of the man and one of the options to satisfy them is through the lambs which contribute to cover them with their meat, wool and skin. For the analysis of the yield a flock took itself from twenty females and a stallion one of Pelibuey race and was developed in conditions of semiestabulado and artificial prairie with oats and rye grass in the north of the State of Sonora.Several indicators were taken to carry out the determination of the yield taking in first instance the capital of work, point of balance, sensitivity analysis as well as the relation benefit-cost. In the case of first the amount of 109.650,44 like so was determined whereas the balance point obtains as of the second period of 270 days... |

| Anemia due to worm infection is a major cause of loss in the sheep industry, due to deaths, drop in average daily gains and long recovery time following treatment. The present experiment was aimed at evaluating the oxidative status and the recovery of red blood cell (RBC) profile in lambs with induced anemia by bleeding, treated or not with dextran iron. Ten ram lambs 5 to 7 months old were used. Blood samples were drawn every other day and when reached packed cell volume (PCV) of 15% were randomly allocated (day zero) to one of the experimental groups. Treated group received a single dose of 25mg per kg body weight of a commercial formulation of dextran iron, the control group received no treatment. Blood samples were taken on days 0, 7, 14, and 21 after... |

| Se realizó un estudio con el objetivo de evaluar el comportamiento productivo y características de la canal de ovinos Suffolk x Hampshire y Pelibuey al adicionar clorhidrato de ractopamina (RAC) en la dieta de corderos en la etapa de finalización. Se realizaron dos experimentos, en el primero se utilizaron 20 corderos machos Suffolk x Hampshire (S x H) con un peso inicial promedio de 37.01 ± 1.04 kg, y en el segundo 28 corderos machos Pelibuey (PB) con un peso inicial promedio 28.37 ± 0.66 kg. La prueba de engorda en corral fue de 45 días con un periodo de finalización de 30 días. Los corderos se alojaron en corraletas con comedero y bebedero individual, el alimento se ofreció a las 08:00 y 16:00 horas y el agua a libre acceso. El RAC se administró en la... |
