On Monomial Flocks

European Journal of Combinatorics, 2001
A flock of a quadratic cone is a partition of a quadratic cone minus its vertex (in 3-dimensional projective space) into plane conics. These objects give rise to a lot of other interesting objects such as translation planes, elation generalized quadrangles, (herds of) ovals, ovoids, regular hyperbolic fibrations, etc. If the associated functions of the

Producing Higher Value Wool through a Transition from Romney to Merino Crossbred: Constraining Sheep Feed Demand

Agriculture, 2021
A strategy to increase wool income for coarse wool (fibre diameter > 30 µm) producers through a transition to higher value medium wool (fibre diameter between 25 and 29 µm) was identified, with previous analyses allowing sheep feed demand increases to ...

Advanced survival models for risk-factor analysis in scrapie [PDF]

, 2007
Because of the confounding effects of long incubation duration and flock management, accurate epidemiological studies of scrapie outbreaks are difficult to carry out.

Groups and Individuals: Optical Flow Patterns of Broiler Chicken Flocks Are Correlated with the Behavior of Individual Birds

Animals, 2021
Group level measures of welfare flocks have been criticized on the grounds that they give only average measures and overlook the welfare of individual animals. However, we here show that the group-level optical flow patterns made by broiler flocks can be

STUDIES ON THE IMMUNE RESPONSE STATUS OF CHICKENS VACCINATED WITH DIFFERENT WITH DIFFERENT NEWCASTLE VACINAL PROGRAMS [PDF]

Veterinary Medical Journal - Giza, 2006
Two commercial breeder chicken flocks of 120 day old were vaccinated by inactivated oil emulsion NDV. The first flock was inoculated with LaSota stain vaccine every 30 days and the other flock was inoculated with the same vaccine every 50 days for 9 ...

Effects of oxygen concentration during incubation and broiler breeder age on embryonic heat production, chicken development, and 7-day performance

Animal, 2021
Older breeder flocks produce eggs with a relatively larger yolk and thereby a higher nutrient availability than young breeder flocks. To optimise nutrient utilisation and embryonic development throughout incubation and posthatch period, embryos ...

Living on the edge: forest edge effects on microclimate and terrestrial mammal activity in disturbed lowland forest in Sumatra, Indonesia

Oryx
Species–environment relationships are often studied at large spatial scales, but effective conservation requires an understanding of local-scale environmental drivers and pressures.

Profitability of dairy and goat production system: A multivariate typology of farm households

Indian Journal of Animal Sciences, 2020
Using households' data from four different agro-climatic zones of Maharashtra, a typology was developed with an aim to identify factors influencing the profitability of dairy and goat production system. Multivariate statistical techniques, i.e.

Allocentric Flocking

Nature Communications
Abstract Understanding how group-level dynamics arise from individual interactions re- mains a core challenge in collective behavior research. Traditional models assume that animals follow simple behavioral rules, like explicitly aligning with neighbors, yet experimental support for such interactions is often lacking. Here we consider a
