Isolation Of Lactoferrin And Its Concentration In Sows’ Colostrum And Milk During A 21-Day Lactation, J. I. Elliot, B. Senft, G. Ernhardt, D. Fraser
Isolation Of Lactoferrin And Its Concentration In Sows’ Colostrum And Milk During A 21-Day Lactation, J. I. Elliot, B. Senft, G. Ernhardt, D. Fraser
Nutrition Collection
Levels of lactoferrin, an Fe-binding protein with bacteriostatic properties, were determined in the colostrum and milk of Yorkshire sows during a 21-d lactation. Lactoferrin levels averaged 1,100 to 1,300 μg/ml near the time of farrowing, then declined sharply during the first week of lactation. Concentration of lactoferrin showed considerable variation among sows, but not among teat positions (anterior to posterior). A method for isolating high purity swine lactoferrin is described.

Some Factors Influencing The Availability Of Colostrum To Piglets, D. Fraser
Some Factors Influencing The Availability Of Colostrum To Piglets, D. Fraser
Physiology Collection
Five experiments, involving the hand milking of 53 farrowing sows, examined aspects of colostrum yield during and soon after farrowing. The initial and abundant yield of colostrum from a teat (averaging 6 to 10 g/min) declined after several minutes of continuous milking. Thereafter, most colostrum was released in discrete ejections, possibly caused by discrete releases of oxytocin. Colostrum ejections varied greatly in their yield and duration, and were sometimes associated with the birth of a piglet, sounds of other sows nursing, or other factors.
Teats varied greatly in their yield. During the initial minutes of milking, the most anterior teats …

The Question Of Animal Awareness, Francoise Wemelsfelder
The Question Of Animal Awareness, Francoise Wemelsfelder
Sentience Collection
The problem of animal awareness lies at the interface of science and philosophy. As a starting point for the study of phenomena such as awareness, mind, consciousness, etc., we hardly have any reference other than our own human experience and in the context of a nondualistic ontology this can be justified. In philosophy and psychology it appears to be very difficult to give direct operational definitions of terms such as consciousness, etc. So we might expect this to be even more difficult in the study of animals. A detailed knowledge of animals and their behaviour is necessary in order to …

Animal Boredom: Is A Scientific Study Of The Subjective Experiences Of Animals Possible?, Françoise Wemelsfelder
Sentience Collection
The aim of this paper is to explore the relationship between different meta-scientific frameworks and the science of animal welfare. Animal Boredom 117 During the past few years, I have become more and more convinced that the great difficulty science has in studying subjective experience in its objects, might be related to the denial of any role to subjective experience in the observer as an interpretational guide. Can a quality in the world around us be observed, when this same quality is deliberately excluded from the process of observing?
As a practical example for the discussion described above, the phenomenon …

This book, the first in an annual series, written by academicians--scientists, philosopher and other--is not intended exclusively for animal welfarists and conservationists. Since it is written by scholars, it will appeal to a wide range of academic and professional readers who are involved with animals for scientific, economic, altruistic, and other reasons. While this first volume cannot cover the entire spectrum of animal welfare science-related topics, it does, in its diversity of contributions, demonstrate the multi-faceted and interdisciplinary nature of the subject of this new series.
