Nitrogen fractionation of certain conventional- and lesser-known by-products for ruminants

The utilization of the products of green-crop fractionation by pigs and ruminants.

Fibrous green crops can be separated by mechanical methods into two fractions: a highquality fibrous feedstuff for ruminants and a liquid rich in protein, sugars and minerals for non-ruminants. The yields of crude protein (CP) (nitrogenx6.~5) which can be obtained from grasses and legume crops are substantially greater than for other methods of crop or animal production (Davys, 1973) (Table I),...

Strategies for optimizing nitrogen use by ruminants.

The efficiency of N utilization in ruminants is typically low (around 25%) and highly variable (10% to 40%) compared with the higher efficiency of other production animals. The low efficiency has implications for the production performance and environment. Many efforts have been devoted to improving the efficiency of N utilization in ruminants, and while major improvements in our understanding ...

Lesser-known bunyavirus infections.

This paper reviews less well-known or less widely distributed viruses of the Bunyaviridae family that are nonetheless of significant veterinary and public health concern. These include: Cache Valley fever, Main Drain, Ingwavuma, Bhanja and Heartland viruses. A description of the agents, clinical signs of infection, epidemiology, and insect transmission is provided for each, and the authors disc...

Lesser known mycobacteria.

Some lesser known Irish physicians.

THE Osler Club was founded to commemorate the name of one of the greatest and best-known physicians of all time, and it seemed fitting that at the Society's first meeting in Dublin the opening paper should try to pay tribute to some other physicians who, given the time, place and opportunity might have become just as well known, but were fated to work in relative obscurity, 'great' only in the ...
