1991 Beef Cattle Report, Darrell W. Nelson

Nebraska Beef Cattle Reports

A two-year study tested the hypothesis that growth rate interacts with bull exposure to influence age at puberty in heifers. Heifers exposed to sterile bulls and fed to achieve a high growth rate (1.8 lb/day) attained puberty 73 days earlier than heifers not exposed to bulls and fed to a moderate growth rate (1.3 lb/day). Heifers exposed to bulls and fed to achieve a moderate growth rate attained puberty at ages similar to heifers not exposed to bulls and fed to a high growth rate. Furthermore. heifers receiving these two treatments attained puberty 23 days earlier than heifers not exposed …

The Western Australian Pig Health Monitoring Scheme, Ashley Mercy

Journal of the Department of Agriculture, Western Australia, Series 4

Over 30,000 slaughter pigs from 245 Western Australian piggeries have been examined for the presence of 16 diseases since the Western Australian Pig Health Monitoring Scheme (PHMS) started in January 1987. The scheme was developed by the author in conjunction with Dr Chris Brennan, a pig veterinary consultant. Monitoring of slaughter pigs is an important part of providing an effective veterinary service to commercial piggeries. It can be used in accreditation schemes and to help in certifying herds free of particular disease

Beef Cattle Production On Surface-Mined Land In Central Appalachia, William O. Thom, H. B. Rice, David Adams, Charles May, Curtis Absher

Agriculture and Natural Resources Publications

Extensive acreages of reclaimed surface-mined land in Central Appalachia are currently producing forages that can be used in beef cattle production. During reclamation, after these areas were graded, they were seeded with grass and grass-legume mixtures to form a ground cover and to reduce soil loss. Usually in the past these areas have not been managed to provide forages for beef cattle, but they can economically support beef cattle production when managed correctly.

The Pesticide Residue Problem In Beef Cattle : Success With Contaminated Power Poles In South Coastal Areas, Bob Mitchell

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australian beef producers faced a major crisis in 1987 because of organochlorine pesticide residues in some Australian beef cattle. We had to react quickly to find the sources of these residues and to keep contaminated cattle out of our abattoirs. Trace-backs led to 269 Western Australian properties in quarantine by the end of 1987. About 85 per cent of quarantined properties had cattle contaminated with pesticide residues from 'broadacre' sources, especially from potato and other horticultural crops. Another 10 per cent of properties were in quarantine because of contamination from basal treatment of timber power poles

Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson

Journal of the Department of Agriculture, Western Australia, Series 4

In July 1987, a meat inspector found liver fluke (Fasciola hepatica) in a cow at an export abattoir at Waroona. This was the first evidence of the liver fluke completing its life cycle in Western Australia. Fortunately, the Department of Agriculture is reasonably confident that a comprehensive drenching programme has eradicated the liver fluke. The establishment of liver fluke in the south-west coastal areas could cause a serious problem for cattle producers and the small number of sheep producers. Stock would need additional drenching, and if it was not carried out effectively production could be lost or stock could die. …
