“…Esta maior variabilidade pode ser decorrente das tomadas de medidas por diferentes pessoas. Mawdsley et al (1996) O sexo teve efeito significativo (P<0,01) em todas as características estudas, exceto altura do costado, comprimento do pescoço e garupa, e largura da cabeça e da anca. O sexo dos animais influenciou a altura da cernelha.…”

RESUMO -O objetivo deste trabalho foi avaliar os efeitos de sexo, sub-região, idade de registro e ano de nascimento sobre 15 medidas lineares (altura da cernelha, altura do dorso, altura da garupa, altura dos costados, comprimento da cabeça, comprimento do pescoço, comprimento dorso-lombar, comprimento da garupa, comprimento da espádua, comprimento do corpo, largura da cabeça, largura do peito, largura da anca, perímetro do tórax e perímetro da canela) do Cavalo Pantaneiro. Foram analisados dados de 1.214 animais coletados pela Associação Brasileira de Criadores do Cavalo Pantaneiro -ABCCP, no período de 1972 a 1991, usando os procedimentos PRINCOMP, CORR e GLM do SAS e o programa GENES. O sexo, a idade do animal na hora do registro, sub-regiões e ano de registro foram fontes significativas de variação. Os animais, em geral, apresentaram tamanhos pequeno a médio, sendo que os animais da sub-região de Corumbá foram, geralmente, maiores que os de outras sub-regiões. A melhor época para avaliar as medidas morfométricas dos animais seria a partir dos 4 anos de idade. As correlações entre altura de cernelha, altura do dorso e altura da garupa foram altas e positivas, porém entre as outras medidas lineares, médias e baixas. No método de agrupamento, também houve variação de tipo de animais.Palavras-chave: ano, idade, equinos, Pantanal, sub-região Evaluation of the Factors which Influence Linear Measurements of the Pantaneiro HorseABSTRACT -The objective of this work was to evaluate the effects of sex, sub-region, age at registration and year of registration, on 15 linear measures (withers height, back height, croup height, midback height, head length, neck length, back-loins length, croup length, shoulder bone length, body length, head width, chest width, hip width, thorax perimeter and shin bone perimeter) of the Pantaneiro horse. Data from 1214 animals were used, registered in the Brazilian Pantaneiro Horse Association, from 1972 to 1991, and analyzed using GLM, PRINCOMP and CORR procedures of SAS and grouping procedures of the GENES program. The sex, animal age at registration, sub-region and year of registration were significant sources of variation for most of the characteristics studied. The animals of the Corumba region were in general larger than the animals from the other regions. Morphological measures should be taken on the animals from 4 years of age. Correlations between hip height, back height and shoulder height were high and positive, but between other measures were medium to low. Using the grouping method there are several grouping of animals by type which need to be further investigated. .

“…These results suggest that there was "substantial agreement" between observers in scoring the animals similarly, but that there was still room for improvement in scoring some of the CLC. Disagreement between observations on the same animal is a known aspect in subjectively assessing different CLC in pigs (van Steenbergen, 1989), sheep , horses (Mawdsley et al, 1996), and cattle (Veerkamp et al, 2002). In addition, some of these studies indicate only moderate repeatability of observations (agreement of scores for one animal assessed multiple times by the same observer) for different CLC.…”

“…Other rules include the costume of the rider, which is modelled on 18 th and 19 th century Menorcan attire, and the rider holding the reins in only one hand. The conformation is of primary interest to breeders and owners, since the overall body shape defines the limits of the range of movement, the function of the horse and its ability to perform (Mawdsley et al, 1996;Rustin et al, 2009). Therefore, the selection to improve the functionality could lead to changes in some morphological traits.…”

Functional conformation and performance in Classic and Menorca Dressage are the main selection criteria in the Menorca Horse breeding program. Menorca Dressage is an alternative Classical Dressage discipline which is exclusive of the Menorca Island, but including a series of movements that the animals perform in the traditional festivities called "Jaleo Menorquín". One of these movements involves the horse raising its forelimbs and standing or walking on its hindlimbs, which is called "el bot". To make the Menorca horse breed more competitive in the equestrian market, it is necessary to understand the genetic background that characterizes the aptitude for Menorca Dressage and its relationship with conformation traits. The analysed data consisted of 15 conformation traits from 347 Menorca horses (200 males and 147 females), with 1,550 performance records in Menorca Dressage competitions. Genetic parameters were estimated using linear and threshold animal models. The heritabilities for heights and lengths were high (0.45-0.76), those for angulations and binary conformation traits were low to moderate (0.10-0.36) as were the scores for dressage performance (0.13-0.21). The results suggest that the analyzed traits could be used as an efficient tool for selecting breeding horses.Additional key words: dressage; morphology; Bayesian; heritability; local breed.* Corresponding author: ge2sobem@uco.es Received: 02-07-13.
