“…Thus, the methods for estimating BW, such as weighing tapes, tables, and mathematical formulas are practical, cheaper, and more appropriate alternatives (Ellis and Holand, 2002;Wagner et al, 2009;Hoffmann et al, 2013). However, the efficiency of these methods may be affected by some horse characteristics (gender, age, pregnancy stage, body score, and breed), as well as features independent of the animals, such as food availability, health status, and environmental conditions (García Neder et al, 2009).…”

-The objective was to evaluate the accuracy of six body weight (BW) estimating methods in Mangalarga Marchador horses (MM) (n = 318): method A -tape placements at three different positions around the thoracic girth; B -Crevat and Quetelec's formula; C -Hall's formula; D -Hintz and Griffiths' table; E -Santos' table; and F -Cintra's formula. For additional analyses, gender, age, and gestational stage were considered. Estimated average BW was compared to the actual scale weight by the paired T test, mean predicted error, and determination coefficient. In the general population, methods A (position 3), B, and C estimated BW that were different from that of the scale. Method A, at positions 1 and 2, was more accurate in predicting the scale weight results compared with all other methods. For pregnant mares, the tape in positions 1 and 2 in method A did not differ from those of the scale. Method A in positions 1 and 2 and the table (method E) may be used to estimate the BW of males and females of different ages and/or gestational stages. To use Methods B and C, correction factors are necessary to precisely estimate the body weights in this breed.

“…The development of weighing tapes is very useful to field professionals and equine owners who do not have easy access to scales (HOFFMANN et al, 2013;MARTINSON et al, 2014). This research aimed to obtain and compare commercial weighing tapes developed for horses and equations to estimate the BW present in the literature, in addition to developing equations for predicting the BW of donkeys, for a specific life stage and breed, making it possible to make weighing tapes.…”

“…Considering the increasing appreciation of the Pêga donkeys, there is a rising need to refine their breeding methods (HOFFMANN et al, 2013). For this purpose, routine actions such as weighing animals using measuring tapes needs to be adapted for specific species and breed, as the existing tapes are personalized for horses (WAGNER & TYLER, 2011) or donkeys of other breeds than Pêga (ELEY & FRENCH, 1993;PEARSON & OUASSAT, 1996;ALUJA et al, 2005).…”

The equations available in the literature to estimate the body weight (BW) of Pêga breed donkeys were evaluated using 25 animals aged 0-6 months and it was proposed an equation for BW prediction. For the measurement of the thoracic perimeter (TP) and for weighing the animals using the weighing tape, the animals were positioned in a forced station on a steep slope. An electronic scale was used for the determination of the BW. Accuracy of linear and nonlinear equations described in the literature was tested for BW prediction based on the animals’ TP, followed by the comparison of these equations with the equation developed in the present study for BW prediction of Pêga breed donkeys. A difference was noted (P<0.001) between the weights obtained on the electronic scale and the weighing tape. Linear and nonlinear equations available in the literature did not present favorable results with the data of the present study. The equation developed for the estimation of donkeys’ BW allowed the development of a weighing tape exclusive for young animals. Further evaluations are required for other Pêga donkey populations to confirm the efficacy of the proposed equation.

“…This minimizes the measurement error that may sometimes occur when the measuring tape is bent on the opposite side of the horse from the person performing the measurement [ 12 ]. In the studies conducted by Marcenac and Aublet [ 13 ], Ensminger [ 14 ], Carroll and Huntington [ 8 ], Jones et al [ 10 ], and Martinson et al [ 15 ], it was found that methods of estimating horse body weight using mathematical formulae have better accuracy than methods of reading BW from measuring tape, whose estimation of body weight compared to the actual weight may differ significantly [ 12 , 16 ]. The aim of the study was to evaluate established formulae for estimating horse body weight from data gathered using measurement tape.…”

Methods of estimating horse body weight using mathematical formulae have better accuracy than methods of reading body weight from measuring tape. The aim of the study was to evaluate established formulae for estimating horse body weight from data gathered using measurement tape. The research was conducted in a group of 299 adult horses and ponies of selected breeds: ponies (n = 58), Polish Noble Half Breed (n = 150), Silesian Breed (n = 23), Wielkopolski Breed (n = 52), and Thoroughbred (n = 16). Body measurements were performed on each horse using a measuring stick and tape. The actual body weight of the horses was measured with electronic scale. Statistical analysis was carried out separately for individual breeds of horses. In each of the research groups formulae were selected, the results of which were closest to the actual horse body weight readings. The use of formulae for body weight estimation can be useful in determining feed dosages and additives, medicines or deworming agents. Regular weight measurement is important for maintaining a healthy horse.
