Research on Contactless Detection of Sow Backfat Thickness Based on Segmented Images with Feature Visualization

open access: yesApplied Sciences
Aiming to address the problem that the existing methods for detecting sow backfat thickness are stressful, costly, and cannot detect in real time, this paper proposes a non-contact detection method for sow backfat with a residual network based on image ...

Identification and characterization of dairy cows with different backfat thickness antepartum in relation to postpartum loss of backfat thickness: A cluster analytic approach [PDF]

open access: yesJournal of Dairy Science, 2022
The objectives of this study were (1) to characterize the interindividual variation in the relationship between antepartum (ap) backfat thickness (BFT) and subsequent BFT loss during early lactation in a large dairy herd using cluster analysis; (2) to compare the serum concentrations of metabolites (nonesterified fatty acids, β-hydroxybutyrate ...

Live animal ultrasonic evaluation of backfat thickness and loin-eye

open access: yesKansas Agricultural Experiment Station Research Reports, 1986
Determination of backfat thickness and loin-eye area in swine is essential for continued genetic progress, and ultimately, pork product acceptance. Leaner, faster growing boars and gilts must be provided by seedstock suppliers to the commercial swine ...
