Evaluates livestock health and performance grazing alternative forages, suggesting effective options for producers in harsh climates.

To assess the impact of prussic acid-free sorghum-sudangrass and pearl millet on livestock health under semi-arid conditions.
Continuous grazing of two forage types over two years.
Monitoring of 24 Angus-cross stockers in 2023 and 30 Angus-cross heifers in 2024.
Biweekly measurement of body weight, blood, urine, and fecal samples.
Data analysis using PROC MIXED of SAS 9.4.
PAF resulted in higher average daily gains (0.94 kg/day) compared to PM (0.59 kg/day).
Both forages had prussic acid levels below toxicity thresholds.
Nitrate levels were significantly lower in PAF than PM, both remaining well below toxicity limits.
No adverse health effects were observed in cattle during or after grazing.

Aviles et al. (2026) studied this question.
