Implication

Observational study reveals seasonal fluctuations in glucose and hair cover across six goat genotypes, suggesting autumn stressors activate the stress axis.

Key Points

To characterize seasonal fluctuations in serum cortisol, glucose concentrations, and hair cover length across six goat genotypes under stall-fed conditions.
Evaluated 30 stall-fed goats across six genotypes: Granadina, Nubian, Saanen, Toggenburg, Alpine, and Saanen x Criollo crosses (n=5 per breed; age 37 ± 3 months; body weight 42.1 ± 3 kg).
Monitored body weight, body condition score, hair cover length at three anatomical regions (neck, rump, belly), and serum cortisol and glucose levels across all four seasons.
Body condition was highest in Crosses, Nubian, and Granadina goats (P<0.001), while Saanen, Toggenburg, and Crosses exhibited the longest neck and rump hair cover (P<0.001).
Serum cortisol and glucose concentrations did not differ significantly among genotypes (P>0.05).
Belly and neck hair cover peaked during winter and spring, whereas fall showed the lowest body condition scores (P<0.001) and most reduced glucose levels (P<0.001).
