Prolactin and wool growth in the Romney ewe : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in animal science at Massey University
… m plasma prolactin (PRL) concentration on wool growth in non-pregnant and breeding Romney ewes were assessed. Seasonal changes in plasma PRL concentration appeared to be primarily determined by photoperiod, rather than ambient temperature. The seasonal winter decline in wool production was …

Compositional Exploration and Microstructural- Environmental Evaluation of Alloys for Glass Vitrification Applications
… of Co-101 alloy spinners used in glass mineral wool production. These components operate under aggressive thermal and chemical conditions that accelerate oxidation and corrosion, limiting service life. To address this challenge, two alloying strategies were explored for Co-101: (i) variations in …

The effect of application of the FAMACHA© system on selected production parameters in sheep
… as can be seen from Tables 4.4.1 to 4.4.3. Wool production was not analysed in this trial due to faulty sample collection at shearing, but ideally it should have been included. Economic evaluation of the data initially showed that there appeared to be a benefit to dosing more frequently. …
