SUMMARY:

This study aims to evaluate the use of weighing tape in pregnant mares as well as to determine the most appropriate equation for estimating the body weight of pregnant mares. Since equine scales are not readily available due to their high cost, measuring tapes are the most common method of measuring body weight in horses. However, these measurements are not always representative of the animal's actual value, with different factors potentially affecting the tape readings. The experiment was carried out in the Equideoculture Productive Didactic Module, Campus II, Center for Agricultural Sciences of the UFPB, located in the municipality of Areia. Four pregnant mares were used, evaluated weekly during the end of pregnancy. Weighing was carried out weekly on a commercial scale, measurement with a3 weight tape for horses; in addition, the collection of biometric measurements was carried out: G1—thoracic circumference; L1—body length from shoulder to ischium; L2—length from elbow to ischium; H—height at withers and N—neck circumference. The use of a weighing tape and the calculation of metabolic weight are effective methodologies in horses. However, for pregnant mares in the final third of gestation, the results demonstrate that the alternative weighing methods differ statistically from the actual weight. It can be concluded that none of the alternative methods proved to be as efficient as the scale for measuring the weight of pregnant mares in the final third. Since Martinson et al. (2014)c the most appropriate method, compared to the other methods studied in this experiment, for pregnant mares in the final third.
