Castrated male Corriedale lambs from Uruguay were finished under one of four feeding systems, which differed in the level of pasture and the amount of concentrates. Treatment 1 (T1) was all pasture (P), T2 was P plus concentrate (C; 0.6% of live weight [LW]), T3 was P + C (1.2% of LW), and T4 was C plus alfalfa hay as a source of fibre (both ad libitum). A trained taste panel analysed samples from 96 lambs, using a quantitative descriptive method in a complete and balanced design. Eight of the 11 sensory attributes were affected by Treatment (p < 0.05). The inclusion of concentrate in the lamb diet improved the sensory quality of the meat, being related to its effect on lowering the intensity of undesirable odours and flavours (strange, rancid and acid), generating higher intensity of typical lamb aromas as well as producing higher tenderness. The frequencies of odour/flavour unsolicited observations also showed disadvantages to pasture feeding. Lambs fed only concentrates (T4) produced meat that had the highest fat flavour intensity and the best overall acceptability given by the panellists. |

ABSTRACT.- In Uruguay, the mortality of dairy calves due to infectious diseases is high. Escherichia coli is a natural inhabitant of the intestinal microbiota, but can cause several infections. The aim of the work was to characterize E. coli isolates from intestinal and extraintestinal origin of dead newborn calves. Using PCR, virulence gene characteristics of pathogenic E. coli were searched. The pathogenic E. coli were molecularly characterized and the phylogroup, serogroup and the Stx subtype were determined. Antibiotic susceptibility was determined using the Kirby-Bauer disk diffusion method and plasmid-mediated quinolone resistance (PMQR) genes with PCR. Finally, clonal relationships were inferred using PFGE. Gene characteristics of the Shiga toxin-producing E. coli (STEC), Enteropathogenic E. coli (EPEC) and Necrotoxigenic E. coli (NTEC) were identified. The prevalence of the iucD, afa8E, f17, papC, stx1, eae and ehxA genes was high and no f5, f41, saa, sfaDE, cdtIV, lt, sta or stx2 were detected. The prevalence of STEC gene stx1 in the dead calves stood out and was higher compared with previous studies conducted in live calves, and STEC LEE+ (Enterohemorrhagic E. coli (EHEC)) isolates with stx1/eae/ehxA genotypes were more frequently identified in the intestinal than in the extraintestinal environment. E. coli isolates were assigned to phylogroups A, B1, D and E, and some belonged to the O111 serogroup. stx1a and stx1c subtypes were determined in STEC. A high prevalence of multi-resistance among STEC and qnrB genes was determined. The PFGE showed a high diversity of pathogenic strains with similar genetic profiles. It can be speculated that EHEC (stx1/eae/ehxA) could play an important role in mortality. The afa8E, f17G1 and papC genes could also have a role in calf mortality. Multidrug resistance defies disease treatment and increases the risk of death, while the potential transmissibility of genes to other species constitutes a threat to public health. © 2023 by the authors.
