Results demonstrate that trans-10,cis-12 CLA is the isomer responsible for inhibition of milk fat synthesis, and de novo synthesized fatty acids were extensively reduced.

Reduced nutrient intake accounted for only 50% of heat stress-induced decreases in milk yield, and feed intake-independent shifts in postabsorptive glucose and lipid homeostasis may contribute to the additional reduction in milkield.

The mechanism by which trans-10, cis-12 CLA inhibits milk fat synthesis includes decreasing expression of genes that encode for enzyme involved in circulating fatty acid uptake and transport, de novo fatty acid synthesis, desaturation of fatty acids and triglyceride synthesis.

A better understanding of the adaptations enlisted by ruminants during heat stress is necessary to enhance the likelihood of developing strategies to simultaneously improve heat tolerance and increase productivity.

The observations indicate that heat-stressed animals employ novel homeorhetic strategies to direct metabolic and fuel selection priorities independent of nutrient intake or energy balance, and markedly alters postabsorptive carbohydrate, lipid, and protein metabolism independently of reduced feed intake.

The New Zealand 10-point scale was compared with the scoring systems in the United States, Ireland, and Australia by trained assessors and results may be useful for comparing/extrapolating research findings from different countries.
Effects of heat stress and plane of nutrition on lactating Holstein cows: I. Production, metabolism, and aspects of circulating somatotropin.

Reduced nutrient intake accounted for just 35% of the HS-induced decrease in milk yield, and modest changes in the somatotropic axis may have contributed to a portion of the remainder.
Invited review: genes involved in the bovine heat stress response.

The variation in EVHL among animals and the central role that HSF1 has in coordinating thermal tolerance suggest that there is opportunity to improve thermal tolerance via gene manipulation, which will lead to opportunities for improved animal performance via altered nutritional management.
