Donald E. Spiers frequently studies issues relating to Thermoregulation and Respiration rate.
Donald E. Spiers focuses mostly in the field of Internal medicine, narrowing it down to matters related to Lactation and, in some cases, Ovulation.
Donald E. Spiers combines subjects such as Serum prolactin, Biotechnology, Thermal strain, Toxicity and Milk yield with his study of Rectal temperature.
His most cited work include:
- Effects of controlled heat stress on ovarian function of dairy cattle. 1. Lactating cows. (204 citations)
- Use of physiological parameters to predict milk yield and feed intake in heat-stressed dairy cows (116 citations)
- Feeding strategies for managing heat load in feedlot cattle. (109 citations)
