Reduced space in outdoor feedlot impacts beef cattle welfare

Fate of coliform bacteria in composted beef cattle feedlot manure.

The link between livestock production, manure management, and human health has received much public attention in recent years. Composting is often promoted as a means of sanitizing manure to ensure that pathogenic bacteria are not spread to a wider environment during land application. In a two-year study (1998 and 1999) in southern Alberta, we examined the fate of coliform bacteria during windr...

Weed seed viability in composted beef cattle feedlot manure.

Manure composting has gained increased acceptance by the beef cattle (Bos taurus) feedlot industry in southern Alberta, Canada. Unlike fresh manure, compost is often promoted as being "weed-free." Studies were conducted with five weed species in 1997 and thirteen in 1999 to examine the effect of feedlot manure composting on weed seed viability. Weed seeds were buried in open-air compost windrow...

ALPHARMA Beef Cattle Symposium: Factors Affecting Feedlot Profitability

vide data on ruminal pH (pH = 6.21 ± 0.34), liquid outflow rate (LOR = 12.1 ± 4.0 L/kg DM), and ruminally digested OM (rdOM = 39.5 ± 10.3 % DM). The LOR is an index of buffer recycling/kg DMI and rdOM is an index of VFA production/kg DMI. The compliled data also included dry matter intake (DMI = 2.81 ± .87 % LW) and Acetate/Propionate ratio (A/P = 3.18 ± 0.89). Data were analyzed using GLM proc...

Brazilian beef cattle feedlot manure management: a country survey.

No information regarding the management of manure from beef cattle feedlots is available for Brazil. To fill this knowledge gap, a survey of 73 feedlots was conducted in 7 Brazilian states. In this survey, questions were asked regarding animal characteristics, their diets, and manure handling management from generation to disposal. These feedlots finished 831,450 animals in 2010. The predominan...
