The aims of this study were, first, to evaluate eye temperature (ET) with infrared thermography and heart rate (HR) measure stress in horses during show jumping competitions their relationship competition results, second, the influence different extrinsic intrinsic factors horse on measurements analysed. One hundred seventy-three Spanish Sport Horses were analysed for ET HR, these taken 3 h before competition, just after it. Two interval also assessed each parameter. Positive significant...

Reproductive traits have a major influence on the economic effectiveness of horse breeding. However, there is little information available. We evaluated use reproductive as selection criteria in official breeding programs to increase efficiency studs, analysing 696 690 records from pedigree data eight Spanish populations, with different purposes. The parameters studied both sexes were age at first foaling (AFF), last foaling, average life and generational interval. In females, interval...

Hair whorls are a hereditary feature in horses that may be associated with temperament and coat color. described as changes the hair pattern take various forms, such circular linear whorls. We first carried out frequency analysis of (circular linear). Next, Generalized Non-Linear Model was computed to assess significance some potential influencing factors, genetic parameter estimation performed. ENDOG software v4.8 used estimate inbreeding coefficient all animals analyzed. It more common...

Summary The purpose of this study was to phenotypic plasticity ability for Show Jumping performance in horses according age differences. For study, 11 352 participations, belonging 1085 grouped by (4‐, 5‐ or 6‐year olds), were analysed. repeatability animal models ( RAM ) and multiple trait MTAM compared. assumed the same covariance components all groups, whereas considered results every at group as different (but correlated) traits. age, sex, starting order training level included fixed...

Abstract. The Blanca Serrana goat is selected for meat production and usually raised in an extensive farm system. industry getting bigger Spain, evolving to more intensive farming systems. negative influence of stress produced by daily management on animal welfare even these animals as they are not used so close humans. Eye temperature has recently appeared appropriate noninvasive tool assessment cattle, but no previous studies have been developed goats. Thus, the main aim this pilot study...

Summary To obtain a sport horse that excels in the highest levels of competition, breeders must take into account certain genetic and environmental factors could influence horse's performance, such as rider–horse interaction (RHI). The main aim this study was to describe model by modelling it relation age. A total 31,129 results from Spanish Sport Horses were used 1,101 animals evaluated, these grouped three age had been ridden 606 different riders. Only riders who more than one (and...

A method to quantify the contribution of subpopulations genetic diversity in whole population was assessed using pedigree information. The standardization between- and within-subpopulation mean coancestries developed account for different coat colour subpopulation sizes Spanish Purebred (SPB) horse population. data included 166264 horses registered SPB Studbook. Animals born past 11 years (1996 2006) were selected as 'reference population' grouped according into eight subpopulations: grey...

Fertility is a key factor in the economic success of horse farms. However, it has received little attention due to difficulty measuring fertility objectively. Since its studbook creation (1912), Pura Raza Española (PRE) breed been closed population and become high in-bred resulting inbreeding depression (poor phenotypic values). Nevertheless, heterogeneous effects have detected among founders nonfounders. The aims this study were (1) analyze genetic parameters for reproductive traits mares...

The way a horse activates (effort phase-EP) and recovers (recovery phase-RP) during sport event can affect its performance. aim of this manuscript was to test horses’ adaptation performance genetic basis, using eye temperature assessed with infrared thermography. EP RP were measured in 495 Spanish Sport Horses, test, considering sex (2) lines (5) as fixed effects. ranking position obtained on an official competition also collected. Differences variables due line effects found, showing that,...

The studbook of Pura Raza Menorquina horses only permits the use black-coated animals with a small quantity white marks as breeding stock. Its program uses linear morpho-functional traits selection criteria. Our aim was to estimate genetic parameters traits, and reveal relationship quality black coat color (QB) percentage (WM) other morphological functional in this breed. A total 46 were scored by four appraisers using seven classes, 772 records from 333 (≥4 years old). Univariate animal...

The equine breeding industry for sport's performance has evolved into a fairly profitable economic activity. In particular, the Caballo de Deporte Español (CDE) is bred different disciplines with special focus on Show Jumping. main aim of this study was to determine effects 15 years selection and find out whether it been effective adequate regarding CDE objectives. whole pedigree 19,045 horses registered as used, comprising 47,884 animals (18,799 males 29,085 females). An analysis performed...

Eye temperature assessed with infrared thermography is an adequate tool for stress level assessment in sport horses’ competitions having a moderate heritability. Serotonin and dopamine signal transduction-linked gene variants have been associated anxiety-related traits several species. In this study we examined the association between 10 BDNF, COMT, HTR1A, TPH2 SLC6A4 genes (and haplotypes at gene) (measured eye heart rate) 270 animals, 135 Spanish Trotter Horses (STH) participating trotting...

Eventing is an equestrian discipline combining dressage, show jumping and cross-country exercises. The Spanish Sport Horse (SSH) was used in this study as example to develop a method ascertain the influence of parental breeds on particular performances by linking their genetic contribution with individual phenotype value computing optimal breed for each trait evaluated eventing. Data included 1220 eventing records from 210 SSH animals. six main founder populations were computed SSH:...

Horses have been valued for their diversity of coat color since prehistoric times. In particular, the pleiotropic effect that genes on behavior determines way horse perceives and reacts to its environment. The primary aim this study was evaluate influence basal reactivity assessed with infrared thermography as eye temperature at rest (ETR), determine relation results obtained by these horses in Show Jumping competitions estimate genetic parameters variable test suitability selection. A...

In clinical examination of rabbits, the temperature is usually recorded with a digital thermometer introduced rectally, an invasive procedure that could cause handling stress. The aim this study was to assess body using infrared thermography (IRT) in four areas rabbit’s anatomy: eye (ETT), outer ear (OETT), inner (IETT) and nose (NTT), then validate it as alternative measure rectal (RT) assessed conventional thermometer. Temperature samples were taken twice week from 48 weaned rabbits...
