Key MethodSix hundred horses of different ages, heights and breeds were weighed on a weighbridge and had their weights estimated by two weigh tapes, 1 and 2, by a formula, and by a visual estimate. For the population as a whole, the most accurate method was the formula (mean [sd] 98.6 [10.6] per cent) closely followed by weigh tape 2 (98.1 [8.1] per cent). Tape 1 and the visual estimate were the least accurate (112.0 [9.3] and 88.3 [20.1] per cent respectively). When the population was divided into two…

Use of height-specific weigh tapes to estimate the bodyweight of horses

Two thousand horses of different ages, heights and breeds were divided into two height groups, and weighed on a weighbridge; each horse then had its weight estimated by three weigh tapes, one height specific and two for general use (tapes 3 and 4).

Assessment of methods for determining body weight based on biometric dimensions in Hucul horses

It can be assumed that the sex and physiological state of the mare need not be taken into account when developing new formulas for estimating body weight, because existing methods for determining the weight of adult Hucul horses are verified.

Evaluation of the Accuracy of Horse Body Weight Estimation Methods

Methods of estimating horse body weight using mathematical formulae have better accuracy than methods of reading body weight from measuring tape.

Practical procedures to body weight estimation and correction factors applied to Campolina horses

ABSTRACT The objective of this study was to evaluate the accuracy of the following six body weight (BW) estimation methods in Campolina (CAM) horses: A - weight tape placed at three different

New formula for bodyweight estimation of thoroughbred foals

This short communication describes a study to verify and compare the accuracy of the Crevat formula proposed by Capitain (1976) with other methods, and to develop the best possible formula using reliable and easy-to-measure variables for use with thoroughbred foals aged from two to 180 days old.

A preliminary investigation into the mineral intake of horses in the UK 1 2

13 The diet of the domesticated horse is influenced by both internal and external variables, such 14 as age, breed, discipline, and workload, as well as the feed brand preference of the owner. 15

Weight estimation and hormone concentrations related to body condition in Icelandic and Warmblood horses: a field study

Some simple and more complex formulas can be used for Icelandic horses even though they are not developed for this breed, as well as the associations between the variables cresty neck score, body condition score, and plasma concentrations of leptin, insulin and cortisol.

Estimated live weight of growing Pêga breed donkeys

EnglishThe equations available in the literature to estimate the body weight (BW) of Pega breed donkeys were evaluated using 25 animals aged 0-6 months and it was proposed an equation for BW
