TL;DR: Feed behavior, IR thermography and glucocorticoids accounted for 18%, 59% and 7% of the total variation associated with RFI, respectively, and these classes of traits have usefulness in the indirect assessment of feed efficiency in cattle.

TL;DR: In this article, the authors used infrared thermography to predict heat and methane production in dairy cattle. But they did not detect physiological events (e.g., heat increment of feeding) in cows.

TL;DR: In this article, the relationship of infrared thermography (IR) and ultrasound measures (US) with the variation in feed efficiency and daily dry matter intake (DMI), alternative models for calculating residual feed intake (RFI) were tested using DMI, average daily gain (ADG), mid-trial body weight (BW), body surface temperature measured using IR, and US (ribeye area, backfat thickness and marbling score) from 154 crossbred bulls.

TL;DR: Early weaning decreased small intestinal IAP V(cap), IAP catalytic affinity, and IAP gene expression, and this may in part contribute to the susceptibility of early-weaned piglets to increased occurrence of enteric diseases and growth-check.

TL;DR: Data indicate that carcass fatness traits and changes in the proportional weight of total viscera may be negatively associated with G:F and that visceral fat weight proportion and trim and kidneyfat weight proportion may be important factors influencing this relationship.
