A SURVEY OF SHEEP MASTITIS IN SOUTHERN BRAZIL Ciência Rural
Vaz,Adil Knackfuss; Jones,James Eirug Thomas.
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...

Romero-Bernal,Jose; Almaraz,Ernesto Morales; Ortega,Octavio Alonso Castelán; Salas,Nazario Pescador; González-Ronquillo,Manuel.
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...

Aragão,Annelize Zambon Barbosa; Teocchi,Marcelo Ananias; Fregolente,Maria Clara Duarte; Gatti,Maria Silvia Viccari; Pires,Alexandre Vaz; Yano,Tomomasa.
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...

Effect of breed and feeding on the carcass characteristics of the Chilote breed lamb Chilean J. Agric. Res.
Ramírez-Retamal,Jorge; Morales,Rodrigo; Martínez,M. Eugenia; de la Barra,Rodrigo.
The Chilote sheep has been developed in an isolated environment, based on grazing lands with low nutritive value belonging to small-scale producers, because of which there is little information about the use of this breed for meat production. The objective of this work was to determine the effects on lamb carcasses of two breeds with different productive purposes and fed on pastures with different nutritional quality. Three groups of lambs were used. The first and second groups were composed of 13 and 11 Chilote lambs respectively, and the third composed of six Suffolk Down lambs. Lambs remained with their mothers, the first group on naturalized pasture and the rest on rangeland. Animals were slaughtered at 90 d of age. Live weight, carcass weight and...

Graminho,Larissa Arnhold; Rocha,Marta Gomes da; Pötter,Luciana; Rosa,Aline Tatiane Nunes da; Salvador,Paulo Roberto; Amaral,Luiz Gonzaga do; Bergoli,Tuani Lopes; Cadó,Lucas Munareto.
ABSTRACT: The objective of this study was to determine the leaf tissue flows in Italian ryegrass (Lolium multiflorum Lam.), in different phenological stages, grazed by lambs, and managed under three herbage allowances (6, 9 and 12 kg DM/100 kg body weight under rotational stocking method. The experimental design was completely randomized, with repeated measures arrangement. Forage allowances determined similar growth and intake flows, actual and potential utilization efficiencies of grass and they were different in the phenological stages of Italian ryegrass. The intake of leaf blade, as a percentage of body weight, was higher in the 12% herbage allowance. Considering leaf tissue flows, Italian ryegrass can be managed in forage allowances that vary between...

Effect of slaughter weight on fat composition in lacha lambs Agrociencia
Horcada-Ibáñez,Alberto; Beriain-Apesteguía,María J.; Chasco-Ugarte,Julia; Indurain-Báñez,Gregorio; Purroy-Unanua,Antonio.
Due to the fact that domestic consumers prefer low fat meat, the lamb production system in Spain is based on slaughtering low weight animals (12 to 24 kg). Lambs in other European countries are slaughtered at higher weights because consumers prefer more intense flavored and fatter meat. Based on evidence that slaughter weight affects fat characteristics, the effect of slaughtering weight on the fatty acid profile of omental (OM), mesenteric (MES), kidney knob (KK), subcutaneous (SC), intermuscular (IN) and intramuscular (IM) fat in Lacha breed lambs was studied. Forty-two male Lacha lambs were raised and slaughtered at 12 (L12), 24 (L24) and 36 kg (L36) live weight. L12 lambs were fed only on mother's milk until slaughter, one month old. L24 and L36 lambs...

Evaluation of carcass traits, non-carcass components and 12th rib analysis of hair sheep supplemented with phosphorus R. Bras. Zootec.
Louvandini,Helder; McManus,Concepta; Dallago,Bruno Steffano; Machado,Bruno de Oliveira; Antunes,Dalton Araujo.
The aim of this study was to evaluate the performance of sheep supplemented with phosphorus (P) using carcass traits and analysis of 12th rib. Twenty male lambs weighing 13.88 ± 2.51 kg and grazing Andropogon gayanus pasture were divided in two treatments of 10 animals each. In group P, animals were supplemented with 3 g phosphorus/animal/day, while in group NP no P supplementation was given. After 82 days the animals were slaughtered and carcass measurements were taken. The 12th rib was also removed for analysis. No significant differences in body weight, carcass yield, or commercial cut weights were found between both treatments, except for liver and kidneys that were heavier in the supplemented group (p=0.0954). The 12th rib analysis showed that the...
