ABSTRACT - This study investigated the effect of a supplement containing whole rice bran and crude glycerin for
21 days before mating on metabolic, productive, and reproductive responses of 28 primiparous suckling beef cows. Cows
were randomly assigned to a control group (CON, n = 14), grazing on grasslands, and a supplemented group (SUP, n = 14),
grazing on grasslands and supplemented daily individually with 1 kg dry matter (DM) of whole rice bran + 550 mL crude
glycerin (224 g kg?1 DM of methanol) per cow. After 33 days of natural mating, cows that had not expressed estrus were
subjected to a fixed-time artificial insemination protocol. Ten days after the insemination program, bulls were reintroduced for
21 days. Supplementation increased milk yield (SUP: 5.7±0.2 vs. CON: 5.0±0.2 kg d?1 ), milk protein content (SUP: 3.1±0.2
vs. CON: 2.8±0.2%), and body weight of cow (SUP: 379±2 vs. CON: 373±2 kg) and calf (SUP: 150±2 vs. CON: 142±2 kg).
Supplementation improved the energy balance, increased plasma concentrations of cholesterol (SUP: 223.2±6.4 vs. CON:
202.1±6.4 mg dL?1) and glucose (SUP: 72.0±1.2 vs. CON: 68.6±1.2 mg dL?1), and reduced non-esterified fatty acids
(SUP: 0.45±0.02 vs. CON: 0.56±0.02 mmol L?1 ). The percentage of cows on superficial anestrous after supplementation was
greater in SUP than in CON group (57 vs. 21%, respectively); however, no difference in final pregnancy rate was found
(SUP: 79 vs. CON: 64%). There was no evidence that the ingestion of crude glycerin with high content of methanol induced
clinical or hepatic disorders. Supplementation of whole rice bran and crude glycerin is not toxic, and can improve the energy
balance, reflecting in increase in milk yield and calf growth, with a slight effect on the reproductive activity- MenosABSTRACT - This study investigated the effect of a supplement containing whole rice bran and crude glycerin for

Abstract
Onion is among the most consumed vegetables in Uruguay, grown in the northwestern and southern regions of the country. The onion supply presents interannual variations associated with significant postharvest losses, mainly caused by bacterial rots. Besides bulb rotting, onion leaf lesions as well as infections on seed-stalks during seed production may be devastating for some varieties under conducive conditions. This research aimed to identify the causal agents of bulb rots and leaf blight of onion crops in Uruguay. Symptomatic bulbs, seeds-stalks, and leaves were collected from commercial fields from 2015 to 2020. Bacterial colonies were isolated and identified at genera level using physiological tests and 16S rRNA gene sequence analysis. A collection of 59 Pantoea spp. isolates was obtained (11 from bulbs and 48 from leaves and seeds-stalks). Multilocus sequence analysis using four housekeeping genes (rpoB, gyrB, leuS, and fusA) allowed the assignment of the isolates to five Pantoea species: P. ananatis, P. agglomerans, P. allii, P. eucalypti, and P. vagans. The last two species were not previously reported as onion pathogens elsewhere. The ability to cause disease symptoms was tested by leaf inoculation and red onion scale assays. P. ananatis isolates showed the highest aggressiveness in both assays. Specific isolates from P. allii (MAI 6022), P. eucalypti (MAI 6036), P. vagans (MAI 6050), and Pantoea sp. (MAI 6049) ranked second in aggressiveness on onion leaves, whereas only three isolates belonging to P. eucalypti (MAI 6036 and MAI 6058) and P. agglomerans (MAI 6045) exhibited the same scale-clearing phenotype as P. ananatis. Leaf inoculation assays were also performed on a set of eight onion cultivars and breeding lines. Overall, P. ananatis MAI 6032 showed the highest aggressiveness in all tested cultivars, followed by P. eucalypti MAI 6036. The presence of new reported bacterial species leads to complex disease management and highlights the need for further studies on virulence factors and the epidemiology of these pathogens.
