ABSTRACT. Hypomagnesemia is a major cause of death in grazing beef cows in countries of the Southern Hemisphere such as Argentina, Australia and New Zealand. Here we review the literature on hypomagnesemia in beef cattle and describe an outbreak in Uruguay. The
disease occurred in late autumn, affecting 6 to 11-year-old Aberdeen Angus and Hereford x Aberdeen Angus lactating multiparous cows in good body condition, grazing on natural grasslands that had been improved by fertilization and sowing of seeds of ryegrass and
oat. Approximately 40 out of 225 cows were affected and 24 (10.7%) died. A presumptive diagnosis of hypomagnesemia was established based on sudden death, acute neuromuscular clinical signs, epidemiological data, and the response to Mg administration. The diagnosis was
confirmed by detecting low Mg concentrations in serum (0.47-0.57mmol/L), vitreous humor (0.47-0.80mmol/L), aqueous humor (0.66mmol/L) and cerebrospinal fluid (0.59mmol/L). The largest component of the diet corresponding to fast-growing and exuberant forages of
ryegrass and oat had high concentrations of K (3.48%), N (4.38%) and P (0.94%), suggesting secondary hypomagnesemia. In addition, the K/(Ca+Mg) ratio was 2.38 in forages of ryegrass and oat (reference value: 2.2), and 0.15 in the soil (reference value: 0.09), which represent
risk factors for hypomagnesemia. In conclusion, hypomagnesemia is an important cause of mortality in beef cattle grazing improved natural grasslands in Uruguay and it can be easily prevented by correct seasonal Mg supplementation.
RESUMO:A hipomagnesemia é uma das principais causas de morte em vacas de corte em pastagem em países do Hemisfério Sul, como Argentina, Austrália e Nova Zelândia. Aqui, revisamos a literatura sobre hipomagnesemia em bovinos de corte e descrevemos um surto no Uruguai. A doença ocorreu no final do outono, afetando vacas Aberdeen Angus e Aberdeen Angus x Hereford de 6-11 anos de idade em boas condições corporais, lactantes, multíparas e pastando em campos naturais que foram melhorados com fertilização e plantio de azevém e aveia. Aproximadamente 40 de 225 vacas foram afetadas e 24 (10,7%) morreram. O diagnóstico presuntivo de hipomagnesemia foi estabelecido com base na morte súbita, sinais clínicos neuromusculares agudos, dados epidemiológicos e a resposta à administração de Mg. O diagnóstico foi confirmado pela detecção de baixos níveis de Mg no soro (0,47-0,57mmol/L), humor vítreo (0,47-0,80mmol/L), humor aquoso (0,66mmol/L) e líquido cefalorraquidiano (0,59mmol/L). O componente mais importante da dieta correspondia a pastagens de azevém e aveia de rápido crescimento, as quais apresentaram altas concentrações de K (3,48%), N (4,38%) e P (0,94%), que sugerem hipomagnesemia secundária. Além disso, a relação K/(Ca+Mg) foi de 2,38 em forragens de azevém e aveia (valor de referência: 2,2) e 0,15 no solo (valor de referência: 0,09), que representam fatores de risco para hipomagnesemia. Em conclusão, a hipomagnesemia é uma causa importante de mortalidade em gado de corte em pastagens naturais melhoradas no Uruguai e pode ser facilmente prevenida pela correta suplementação sazonal de Mg.

ABSTRACT:
Stem rot and aggregated sheath spot are the two major stem and sheath diseases affecting rice (Oryza sativa L.) in temperate areas. A third fungal disease, sheath blight, is a major disease in tropical areas. Resistance to these diseases is a key objective in rice breeding programs but phenotyping is challenged by the confounding effects of phenological and morphological traits such as flowering time (FT) and plant height (PH). This study sought to identify quantitative trait loci (QTL) for resistance to these three diseases after removing the confounding effects of FT and PH. Two populations of advanced breeding germplasm, one with 316 tropical japonica and the other with 325 indica genotypes, were evaluated in field and greenhouse trials for resistance to the diseases. Phenotypic means for field and greenhouse disease resistance, adjusted by FT and PH, were analyzed for associations with 29,000 single nucleotide polymorphisms (SNPs) in tropical japonica and 50,000 SNPs in indica. A total of 29 QTL were found for resistance that were not associated with FT or PH. Multilocus models with selected resistance-associated SNPs were fitted for each disease to estimate their effects on the other diseases. A QTL on chromosome 9 accounted for more than 15% of the phenotypic variance for the three diseases. When resistance-associated SNPs at this locus from both the tropical japonica and indica populations were incorporated into the model, resistance was improved for all three diseases with little impact on FT and PH.
