Animal production, and some related problems, in southland Part II

Abstract

Extract

I have stressed the winter feed position, because the main period of hazard from an animal health point of view occurs in Southland towards the end of the winter, and especially in what has been referred to as the “buffer period.” The primary problems are essentially man-made, and consist of the so-called “metabolic disturbances” to which domestic ruminants appear to be particularly susceptible during increased metabolic activity, concurrent with advancing gestation and onset of lactation. These are Pregnancy Toxaemia, Acetonaemia, Haemoglobinurea, Hypocalcaemia, Lactation Tetany, etc.
