Genetic parameters of longevity in crossbred Mule ewes, and genetic relationships among longevity, growth, body composition, and subjectively assessed traits on Mule lambs and ewes have been estimated using Bayesian linear censored models. Additionally, the genetic associations between longevity and culling reasons were examined. Data comprised 1,797 observations of Mule ewes for longevity, cul...

Bovine tuberculosis is an important disease affecting the UK livestock industry. Controlling bovine tuberculosis (TB) is made more complex by the presence of a wildlife host, the Eurasian badger, Meles meles. Repeated large-scale badger culls implemented in the Randomised Badger Culling Trial (RBCT) were associated with decreased cattle risks inside the culling area, but also with increased cat...

Visibility culling of a scene is a crucial stage for interactive graphics applications, particularly for scenes with thousands of objects. The culling time must be small for it to be effective. A hierarchical representation of the scene is used for efficient culling tests. However, when there are multiple view frustums (as in a tiled display wall), visibility culling time becomes substantial an...

One of most pertinent and acute risks that the world is now facing is emerging or re-emerging zoonotic diseases. This article focuses on culling as a measure for zoonotic disease control, specifically the culling of 11,000 badgers as part of the Randomized Badger Culling Trial in the UK and the culling exercises in Singapore. The independent expert panel that devised the UK study concluded that...

An exact transformed culling method for any number of traits or stages of selection with explicit solution for multistage selection is described in this paper. This procedure does not need numerical integration and is suitable for obtaining either desired genetic gains for a variable proportion selected or optimum aggregate breeding value for a fixed total proportion selected. The procedure has...

The aim of this simulation study was to identify culling strategy and to estimate culling precision based on various characteristics available in field data in order to evaluate the ability to detect situations in which adjustment for missing data should be applied in genetic evaluation. Data were simulated for age at 100 kg of live weight (AGE) measured on the farm. Culling was done within (C-...

Data from a prospective longitudinal study carried out from 1986 to 1990 in 47 commercial Holstein dairy herds from western France were used to quantify the effects of udder health disorders on the risk of culling. Logistic regression was used to assess the relationship between 4 udder health disorders and early and late culling. Teat injuries were associated with an increased risk of early cul...

Ray tracing [Appe68] [Gold71] is widely acknowledged as a rendering approach that can produce very realistic and beautiful images [Whit80]. It is also widely known that ray tracing is very expensive computationally. Many intersection culling algorithms have been proposed to reduce this expense. However, such intersection culling algorithms do not take into consideration the nature of the primit...

the majority of bovine lameness involves structures of the digit. a prompt identification of problematic cases is needed to be done for prevention of premature culling decision. this cross-sectional and descriptive study was carried out at an abattoir in the vicinity of tehran. 41 cases of culled lame cows, with special reference to the claw lesions and their distribution were randomly selected...
