Nutrient Requirements of Domesticated Ruminants
Nutrient Requirements of Domesticated Ruminants draws on the most up-to-date research on the energy, protein, mineral, vitamin and water requirements of beef and dairy cattle, sheep and goats. It defines the responses of animals, in weight change, milk production and wool growth, to quantitative and qualitative changes in their feed supply. It has particular application to grazing animals. Factors affecting the intake of feed are taken into account and recommendations are given according to the production systems being used; for instance, the feed intake of a grazing animal is affected by a larger number of variables than a housed animal. Examples of the estimation of the energy and nutrients required for the different production systems are given, as well as the production expected from predicted feed intakes. The interactions between the grazing animal, the pasture and any supplementary feeds are complex, involving herbage availability, diet selection and substitution. To facilitate the application of these recommendations to particular grazing situations, readers are directed to decision support tools and spreadsheet programs. Nutrient Requirements of Domesticated Ruminants is based on the benchmark publication, Feeding Standards for Australian Livestock: Ruminants, published in 1990 by CSIRO PUBLISHING on behalf of the Standing Committee on Agriculture. It provides comprehensive and useful information for graziers, livestock advisors, veterinarians, feed manufacturers and animal nutrition researchers. The recommendations described are equally applicable to animals in feedlots or drought yards..

The Kedrigern Chronicles Volume 1: The Domesticated Wizard (The Kedrigern Chronicles, Volume 1)
A wizard's life is not an easy life. One never knows who, or what, one's next client will be, or what kind of unpleasantness he, or she, or it, is bringing. And there's always the certainty of travel to far places over bad roads in nasty weather. It's no wonder wizards prefer to live solitary lives in isolated towers or ruins or caves. They're looking for some peace and quiet. But it makes for a lonely life. So when a young man of 160 or so-no age at all for a wizard-meets a beautiful enchanted princess and releases her from a cruel spell, it seems the perfect chance to settle down to a life of cozy domesticity. With a bit of magic here and there to take care of the housework and a loyal house-troll to do the heavy lifting, things ought to be idyllic. And they would be, if it weren't for the unreasonable clients, the barbarian swordsmen, the home furnishings with minds of their own, the otherworldly intruders, and the rest of those annoying day-to-day problems of the profession. This is the first of four omnibus reprints of the novels and short stories of Kedrigern the Wizard. Kedrigern Chronicles #1 contains the two novels A Voice for Princess and The Questing of Kedrigern along with the following six short stories: 'Spirits From the Vasty Deep', 'Hey, Ho, The Wind and the Rain', 'The Quality of Murphy', 'Mirror, Mirror, Off the Wall', 'Nest Egg', and 'Floored'. Along with new introductions to the novels and short stories by John Morressy.
