Incidence of rotavirus in beef herds in Argentina

Faecal samples were collected from 177 diarrhoeic and 40 healthy calves from 19 farms in Buenos Aires State, Argentina during 1984 and 1985. Samples were examined for rotavirus by enzyme-linked immunosorbent assay (ELISA) and polyacrylamide gel electrophoresis (PAGE) of their genomic RNA segments. Rotavirus was found in 95 samples of diarrhoeic calves (53 per cent) and in three healthy calves (7 per cent). All positive samples were tentatively classified as group A on the basis of electropherotype and ELISA test reactivity and exhibited 18 different genomic electropherotypic patterns.     

我国牛肉的国际贸易与对策

为迎接畜牧产品的国际化，关于我国牛肉的国际贸易，我国应当利用国内目前市场不缺肉机遇，尽快调整思路，研究应对开拓国外市场的新布局。近年来，我国牛肉生产发展很快，也是随经济发展，肉食结构调整的结果，牛羊肉增长速度超过猪肉。2003年世界牛肉产量5874．2万吨，占世界总肉量的23．51％。因贸易数据最近是2002年。故本文统计数据一律采用2002年数据。世界牛肉产量5788．3万吨，基本结构没有变(23．62％)。我国产量是532．0万吨，占世界总产的9．19％。在世界牛肉产量中属于中等。     

我国牛肉的国际贸易与对策

为迎接畜产品的国际化。现提供关于牛肉国际贸易研究，以此为业界提供一些思路和参考意见。我国应当利用目前国内市场已基本实现自给自足的机遇，尽快调整思路，研究应对、开拓国外市场的新策略。     

牛肉生产与市场预测

我国牛肉生产类型复杂，有草地放牧饲养、异地育肥、老残牛淘汰，也有现代精饲料育肥。因此，质量、成本、价格都有很大差别。活牛饲养期长，可能同一头牛，数次移地，出栏和产量准确性低。我们尽量以价格和数量结合，分析肉牛市场，力求建议意见的准确。

Antimicrobial usage and resistance in beef production

Antimicrobials are critical to contemporary high-intensity beef production. Many different antimicrobials are approved for beef cattle, and are used judiciously for animal welfare, and controversially, to promote growth and feed efficiency. Antimicrobial administration provides a powerful selective pressure that acts on the microbial community, selecting for resistance gene determinants and antimicrobial-resistant bacteria resident in the bovine flora. The bovine microbiota includes many harmless bacteria, but also opportunistic pathogens that may acquire and propagate resistance genes within the microbial community via horizontal gene transfer. Antimicrobial-resistant bovine pathogens can also complicate the prevention and treatment of infectious diseases in beef feedlots,threatening the efficiency of the beef production system. Likewise, the transmission of antimicrobial resistance genes to bovine-associated human pathogens is a potential public health concern. This review outlines current antimicrobial use practices pertaining to beef production, and explores the frequency of antimicrobial resistance in major bovine pathogens. The effect of antimicrobials on the composition of the bovine microbiota is examined, as are the effects on the beef production resistome. Antimicrobial resistance is further explored within the context of the wider beef production continuum, with emphasis on antimicrobial resistance genes in the food chain, and risk to the human population.     

Biochemical and Haematological Measurements in Beef Cattle in Mendoza Plain Rangelands (Argentina)

Biochemical and haematological measurements were used to identify constraints on productivity in beef cattle. One hundred and twelve Aberdeen Angus and Criollo Argentine females including lactating cows, dry non-pregnant cows and heifers were selected. Blood samples were taken in the middle of summer and autumn. Serum was analysed for haemoglobin, PCV, glucose, albumin, urea, creatinine, Ca, P, Mg, Fe, Cu, ALP, AST, ALT, CK, LDH, Cl∼, Na and K content. Globulin was calculated by taking the difference between total protein and albumin. Percentages of all cattle that had metabolite levels outside reference ranges were: 15% (glucose), 8% (globulin), 5% (urea), 96% (Ca), 50% (P), 12% (Mg), 20% (Na), 5% (K), 24% (Cl), 18% (Fe), 5% (Cu) and 85% (CK). These results indicate with some certainty that dietary protein was not limiting. Body condition score loss was detected only in lactating cows. There were a few animals that could have presented chronic inflammatory disease. Phosphorus could be an important potential constraint on fertility, although the presence of symptoms of hypophosphataemia was not observed. The study also demonstrates the absence of anaemia or liver disease. Breed, seasonal and physiological state differences in some blood metabolites could be attributed to one or more of the following factors: chemical composition of the feed ingested, environmental temperature, nutrient content of the forage, animal age and cattle foraging experience. The study provides a basis for implementing helpful adjustments in current cattle management practices so as to alleviate the constraints on productivity, provided that these practices are profitable.
