Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Summary

This summary is machine-generated.

Live stall lameness scoring (SLS) is a practical method for identifying lame dairy cows in tie-stalls, comparable to video analysis. This method offers high accuracy and reliability for herd lameness assessment.

Background:

Lameness is a significant welfare and economic issue in dairy cattle.
Video locomotion scoring (VLS) is established for lameness evaluation, but tie-stall environments present unique challenges.
Video stall lameness scoring (SLS) offers a potentially more practical alternative for tie-stall housing.

Purpose of the Study:

To compare the accuracy and reliability of live SLS against video SLS and live locomotion scoring in tie-stall dairy cows.
To evaluate the feasibility of live SLS as a standalone method for lameness detection in commercial herds.
To assess the prevalence of specific behavioral indicators associated with lameness in tie-stall conditions.

Main Methods:

A total of 685 lactating cows from 27 commercial dairy herds were assessed using live and video SLS.
Four behavioral indicators (weight shifting, standing on stall edge, uneven weight bearing while standing/moving) were recorded.
Live SLS was validated against video SLS as the gold standard; a subsample also underwent live locomotion scoring.

Main Results:

Lameness prevalence was similar between video SLS (31%) and live SLS (30%).
Live SLS demonstrated high sensitivity (0.83) and specificity (0.94) compared to video SLS.
Live SLS showed strong correlation with video SLS (r=0.91) and live locomotion scoring (r=0.92) at the herd level, though it tended to underestimate prevalence compared to locomotion scoring.

Conclusions:

Live SLS is a reliable and practical method for identifying lame cows in tie-stalls, comparable to video-based assessments.
It can be effectively used to rank herds by lameness prevalence without removing cows or requiring video playback.
While accurate, live SLS may underestimate lameness prevalence compared to traditional locomotion scoring methods.
