History

Stirling Wean Ratio and NLW Ratio both began in 2009 and were accrued as a lifetime event at the same time.

Linkage was tried by passing the dams figures onto the ewe progeny as a single year event but… Continue reading →

In 1986 I called at the farm of L.A Pockley of “Pylara” Tarago NSW. He had presented a paper to a Measurement Conference in 1978 beginning the march to the start of LAMBPLAN in 1985. Below is a summary with… Continue reading →

Inflation
Inflation is somewhat like Bacon’s description of hope, it provides a mighty breakfast but leaves you pretty hungry by supper. Many stud breeders pursue the art of index inflation by crossing different strains of blue ink, morally questionable but… Continue reading →

Data collection dating back to 1974 was fed into the databank of LAMBPLAN which began in 1985 incorporating 8 major breeds, Poll Dorset, White Suffolk, Texel, Merino, Suffolk, Border Leicestor, Corriedale and Coopworth.

As LAMBPLAN grew Dr Arthur R Gilmore… Continue reading →

Introduction
In 2005 when Stirling Dohne Stud started, I found the productivity of the breed almost mind-blowing but so were their faults. I took an early interest in muscle but then realized that the wool had to be corrected to… Continue reading →

The Effects of Gravity
Grazing mammal figures can be extremely variable, but approximately for every ten-fold increase in adult weight, fecundity halves, conversion rate doubles, metabolism decreases and food fibre consumption percentage increases. A 60kg sheep is capable of 1.3… Continue reading →

As a child before the  advent of  thibenzole sheep drench I remember both parents dagging sheep until well after 10PM completely enclosed by an 8 feet high edifice, stretching perhaps 20 feet to the horizon.

Before this time… Continue reading →

“Just like Showing,” ASBV’s are tapping into the “individual survival driven” human desire for size. Efficiency conversion rate is roughly inversely proportional, for every 10-fold decrease in bodyweight, conversion rates halve and hence roughly the rate of cattle is 8-1;… Continue reading →

ABSTRACT – Theory’s

• Kleibers Metabolism Theory says that bigger animals have a lower metabolism per unit weight by a factor of 75%.
• It is often assummed that this supports increased size… Continue reading →
