Record of performance data taken on Yorkshire pigs on-farm in 123 breeder herds and at a central test station were used to estimate genetic correlations between measures of backfat depth and days to 90 kg on boars at the test station and boars and gilts on-farm. The data involved records on 3,513 station-tested boars, 13,760 farm-tested boars and 28,203 farm-tested gilts from 838, 2,098 and 2,3...

The biosecurity status of 95 breeder-finisher pig herds was quantified using a risk-based weighted scoring system. Data relating to herd-, farmer- and production-characteristics and to the prophylactic use of antimicrobials were also collected. The average external biosecurity score (measures to prevent pathogens from entering a herd) was 65 (range, 45-89) and the average internal score (measur...

Neurosurgeons and psychiatrists who favor psychosurgery sometimes show dismay that anyone would accuse them of harboring political aims, and it is true that the average psychosurgeon has little or no interest in the application of his technology to overtly political problems. But it is equally true that several of the nation's leading psychosurgeons have persistently linked their work to the co...

OBJECTIVE To compare the owner-reported prevalence of behavioral characteristics in dogs obtained as puppies from pet stores with that of dogs obtained as puppies from noncommercial breeders. DESIGN Cross-sectional study. Animals-Dogs obtained as puppies from pet stores (n = 413) and breeder-obtained dogs (5,657). PROCEDURES Behavioral evaluations were obtained from a large convenience samp...

Common root rot caused by Cochliobolus sativus is a serious disease of barley. A simple and reliable method for assessing this disease would enhance our capacity in identifying resistance sources and developing resistant barley cultivars. In searching for such a method, a conidial suspension of C. sativus was dropped onto sterilized elongated subcrown internodes and incubated in sandwich filter...

automatic flyproof latrine seat, a few points about fly-breeding will not be out of place. These points actually drew my attention to the necessity for an automatic device which I think is essential in dealing with the problem. There is a general belief that fly-breeding occurs mainly in manure and rubbish heaps, and consequently efforts are made to stop breeding in such materials rather than i...
