Feeding order of sows at an individual electronic feed station in a dynamic group-housing system

Applied Animal Behaviour Science, 1993
Abstract Patterns, in the use of a feed station, by sows, in a dynamic group-housing situation, were studied because deviations from such patterns might indicate disease, oestrus, reproductive or other problems. Groups of ten sows of various parities were transported to our experimental farm on the day their piglets were weaned.

Multifrequency band earth station feed design

International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990
The authors present a dual-polarized frequency reuse feed that not only operates in the C-, X-, and Ku-bands but also has significantly extended bandwidths, >800 MHz in C-band and >1.5 GHz in Ku-band. Design issues are discussed, and measurement results are presented. The feed was retrofitted on a 13-m Cassegrain antenna.

Initial experiments with an electronic feeding station for ewes

Acta Agriculturae Scandinavica, Section A — Animal Science, 2014
AbstractThrough four different experiments we investigated the effect of design of an electronic feeding station (EFS) and management factors on the behaviour of ewes. Eighty-nine percent of the ewes had completed their first visit to the EFS within the first six hours, but a major proportion of all rewarded visits were interrupted by displacements ...

Operant Performance at a Feeding Station in Rural Pennsylvania

The Psychological Record, 1982
Frequencies of operant responses for food, feeding bouts, and pecks at a food hopper were recorded in three successive winters at a rural feeding station for a mixed-species flock of wild passerine birds. Only one species in each winter performed the operant response, while nine other species did not work for the food they took, and thus benefited from

Feeding station behavior of free-grazing sheep

Applied Animal Behaviour Science, 1989
A study was conducted in the Middle Atlas Region, Morocco, to investigate the feeding station (FS) behavior of free-grazing sheep during November 1986 and April, June and September 1987. Behaviors observed and recorded were number of FS min−1, time elapsed per FS (T/FS), bites/FS and dry matter intake per FS (DMI/FS). The number of FS min−1 was highest

Design and Construction of Power Station Feed Heaters

Proceedings of the Institution of Mechanical Engineers, 1960
The paper presents a survey of a number of aspects of the design and construction of feed heaters for present-day steam-turbine cycles. Many papers have been published in recent years which cover a variety of the detail factors which can enter into the design of a feed heater (for example, the design of tube plates).
