“…Garcia et al (2009) constatou que dos trinta potros Mangalarga Marchador avaliados, 25 (86,6%) apresentaram osteoartrite társica juvenil. Gallio et al (2014) avaliando potros de semelhante faixa etária, da raça Crioula e também preparados para exposição morfológica, determinou a ocorrência de alterações radiológicas em 79,2% dos animais avaliados.…”

“…Reiterando essa hipóte-se, foi observada uma correlação positiva entre o acúmulo de gordura na crista do pescoço com o grau de comprometimento articular dos potros avaliados. Dado semelhante foi observado por Gallio et al (2014), que concluíram que o fator predisponente para as lesões articulares mais observado foi a excessiva deposição de gordura, traduzida pelo aumento no escore corporal e de deposição de gordura na crista do pescoço dos animais. Consequentemente, o excesso de peso pode levar a uma sobrecarga mecânica da articulação társica que, em conjunto com exercício físico em excesso, resulta no desenvolvimento da osteoartrite társi-ca juvenil.…”

High carbohydrate diets are increasingly used in horse rearing systems. This can result in weight gain and fat accumulation in young horses. There is a growing incidence of juvenile osteoarthritis and other inflammatory conditions in overweight young horses that undergo intense physical exercise. The aim of this study was to associate corporal adiposity with energy profile, serum concentration of acute phase proteins and presence of osteo-articular lesion in the tarsal region of young horses raised in two different rearing systems: intensive system and extensive system. We evaluated 40 young horses 18 months old, 23 of them were females and 17 were males. Twenty horses were raised in the extensive rearing system and twenty horses were raised in intensive rearing system. Blood samples were collected for biochemical analysis and protein electrophoresis. Fat deposition on the crest of the neck, peritoneum and tailhead was measured by ultrasonography. Radiographic examination of the left tarsus was performed in 17 horses of the farm rearing system and in nine horses of the extensive rearing system. We observed higher levels of total cholesterol, LDL, glucose, serum amyloid A (SAA), transferrin, haptoglobin, acid glycoprotein and unidentified protein 23Kda in horses of the intensive system. These horses also showed higher fat deposition on the crest of the neck, peritoneum and tailhead than horses raised on extensive system. All horses on the intensive system group that underwent radiographic examination had lesions compatible with juvenile osteoarthritis while only 23% of the animals of the extensive system group showed such changes. With Fisher's exact test we observed that horses of the intensive rearing system are 105% more likely to develop osteoarthritis than horses of the extensive rearing system. With the Pearson correlation test we found a positive correlation between fat deposition on the crest of the neck and degree of articular injury. Fat deposition on the crest of the neck also showed a positive correlation with serum levels of LDL, glucose, acid glycoprotein, haptoglobin, transferrin and SAA. The SAA correlated with the thickness of retroperitoneal fat. There was a positive correlation between retroperitoneal fat deposition and presence of osteoarticular abnormalities. In conclusion, fat deposition on the crest of the neck has a correlation with energetic profile changes, cute phase proteins changes and with articular injuries.

“…Several researchers have assessed the growth rates of different horse breeds and reported that growth rate is greatest in the first Pimentel et al year of life (HINTZ et al, 1979;SANTOS et al, 1995;REZENDE et al, 1998). Furthermore, studies have also shown a high incidence of developmental orthopedic diseases (DOD) when foals have a high growth rate (GALIO et al, 2014). Therefore, it is important to establish an ideal growth rate for each breed.…”

“…No período de desmame (5 a 7 meses) o desenvolvimento tende a ser menor, situação observada em diversas raças, principalmente pelas alterações relacionadas a dieta, com substituição de nutrientes facilmente digestíveis do leite por dieta de forragens e concentrado [16]. No período pós desmame muitos potros são iniciados no preparo para provas morfológicas tendo predisposição a lesões ortopédicas por erro de manejo [2,9]. Dos 7 aos 24 meses de idade os potros apresentaram um incremento constante em altura, fato justificado pelo crescimento linear dos ossos longos, o que ocorre enquanto ainda não ocorreu o fechamento total das fises [1].…”

Background: Breeding of Crioulo horses in the southern region of Brazil is very significant. Notwithstanding, not all animals meet the standards defined for the breed, raising concern among breeders, owners and veterinarians, driving them to an effort to know and understand the development of Crioulo foals. In order to get a registry at Brazilian Association of Crioulo Horse Breeders (ABCCC), the foals must be presented to a certified technician as of 24 months of age and show the breed standards and measurements required. To date, there are no data concerning development of this breed available. Therefore, this study aims to describe the growth curve of Crioulo foals in the south region of Rio Grande do Sul.Materials, Methods & Results: The study was conducted in three Crioulo horse breeding farms in the cities of Santa Vitória do Palmar, Bagé and Aceguá, in the state of Rio Grande do Sul, Brazil, for a period of two years (2013-2015). We followed up on 267 Crioulo foals from birth up to 24 months of age. Biometric evaluation was divided in 26 periods, with 40 animals in each and random repetition of individuals. Period one: birth to seven days; period two: seven to 21 days; monthly from 1st to 24th month. The three breeding farms presented similar environmental conditions and the horses were submitted to similar management. Measurements were taken on a monthly basis, using a mechanical scale for weight and a hippometer for height. The analysis were conducted on SAS/ETS® version 9.2. Logistic non-linear regression model was used to obtain growth curves for height and minimum, medium and maximum weight of the foals on their respective ages, by this way six growth curves were produced. Results show an increase in weight and height at 24 months of age compared to the moment of birth. This increase was accentuated during the first months of life, both in weight and height. Thus, it is possible to observe that the first six months of life is characterized by a larger growth rate and is therefore, essential for the foals development, requiring special attention from the breeder and owner.Discussion: The growth curve obtained show that not all individuals reach the measurements required by the breed’s association, corroborating the empirical observation of breeders and technicians in their routine. This is also a concern related to other Brazilian breeds such as Mangalarga Marchador, Pantaneira, Campeira. For the mentioned breeds, the adequate growth curve has already been described aiming to controlling foal development. The ABCCC require that foals as of 24 months of age have the minimum values of 1.40 m 1.38 m and 1.38 m; and maximum values of 1.50 m, 1.48 m and 1.50 m, for males, females and geldings, respectively, in order to receive the Association brand and the permanent registry. According to the growth curve, the first two months of the foal’s life show the largest growth rate, reaching 78.4% of an adult’s height with average growth of 20 cm, reaching 1.05 m. Genetic features, nutritional and sanitary conditions, directly influence this period. Overweight associated to exercising increases the risk of musculoskeletal injury and represent a factor for stress on the joints. This should be a concern among Crioulo breeders and the knowledge of their growth curve is important for an objective assessment seeking for a gradual and weighted development. In this work, it was possible to determine the growth curve of Crioulo breed foals in the south region of Rio Grande do Sul, from birth up to 24 months of age, providing minimum, medium and maximum parameters referring to withers height and body weight.
