Liver abscesses in feedlot cattle: a review.

Abstract: Liver abscesses in slaughtered beef cattle result from aggressive grain-feeding programs. The incidence, averaging from 12 to 32% in most feedlots, is influenced by a number of dietary and management factors. Liver abscesses represent a major economic liability to producers, packers, and ultimately consumers. Besides liver condemnation, economic impacts include reduced feed intake, reduced weight gain, decreased feed efficiency, and decreased carcass yield. Fusobacterium necrophorum, a member of the ruminal an… Show more

“…De acordo com a literatura, a principal causa dos abscessos hepáticos encontrados em bovinos abatidos nos matadouros e frigoríficos é proveniente de quadros prévios de ruminites, desencadeados inicialmente por distúrbios digestivos, em especial, pela acidose ruminal 3,4,5,6,7,8,9,10,11 .…”

“…Os abscessos hepáticos causam uma redução em até 11% no ganho de peso diário, redução de 9,7% na eficiência alimentar e diminuição na taxa de crescimento de 5,85% a 12,7% nos animais acometidos, o que pode ocasionar um grande impacto econômico para os pecuaristas e demais elos ligados à cadeia da carne 8,12,13,14,15,16 .…”

“…One major reason for the development of LAs in this feeding situation is associated with the so-called: rumen acidosis-ruminitis-LA complex (Jensen et al, 1954;Scanlan and Hathcock, 1983;Nagaraja and Chengappa, 1998). Free access to concentrates leads to a low intake of straw of which calves rarely consume more than 7% to 8% of total dry matter intake (DMI) (Owens et al, 1998;Jørgensen et al, 2007).…”

“…Feeding high proportions of barley in the diet for steers (Ramsey et al, 2002) showed similar results. Risk of LA is related to a low rumen pH and acidotic conditions seen for several hours over the day because of comparable types of high-concentrate feeding (Scanlan and Hathcock, 1983;Nagaraja and Chengappa, 1998).…”
