The drastic changes that resulted from the COVID-19 pandemic presented ample opportunity to investigate how unwanted horses are impacted by challenging circumstances. Study objectives were to evaluate the COVID-19 pandemic's impact on the unwanted horse population and determine the current perceptions of horses in-transition. A 23-question online survey designed using QualtricsTM was administered electronically to adults living in the United States. Questions pertained to effects on equine ownership, equine management, event participation, and perceptions of unwanted horses. Frequency analysis combined with Chi-squared analyses and analyses of variance identified the impacts of COVID-19 on horse owners, non-horse owners, and equine professionals. From survey results, equine ownership, management practices, and time spent with horses proved to be unaffected (P < 0.001) by the coronavirus pandemic. A decreased ability to participate in equine events was evident across all groups (P ≤ 0.03). Financial hardship, unmanageable behavior, and injury were cited as leading causes for horses becoming \"in-transition.\" Euthanasia was the transitioning method perceived as most accessible, while donation to an equine program was least accessible. Based on results, the COVID-19 pandemic had negligible impact on the number of unwanted horses in the United States.

The median age was 8 years, the majority being warmblood and geldings with a mean bodyweight of 542.4 ± 101.9 kg. Most horses (85 %) had access to a limited area of pasture (<200m2 per horse), with a median grazing time of 10 hours. Grass hay was the predominant conserved forage offered (77 %) within diets. Concentrate feeds were provided to most horses (93.8 %) as well as the dietary supplements (80 %). The majority of the horses were offered high levels of metabolizable energy (ME) (90 %), starch (mean 2.4 ± 0.8 g/kg bw) and sugar intake (mean 1.4 ± 1.2 g/kg bw) compared to NRC recommendations. The estimated potential nitrogen excretion per horse per day was 228 ± 134 g, or 8.47 kg of nitrogen per ton of manure. Consequently, the estimated daily fecal excretion rates of microminerals for each horse were as follows: Copper (Cu) at 141.0 ± 151.3 mg, Zinc (Zn) at 593.1 ± 504.4 mg, Manganese (Mn) at 957 ± 541.2 mg, and Cobalt (Co) at 2.3 ± 3.5 mg.
