Growth Rate of Thouroughbreds. Effects of Age of Dam, Year and Month of Birth, and Sex of Foal

Sexual dimorphism in Hucul horses using discriminant analysis

“…They observed that width of thurls, chest circumference and width of hips were important traits for discriminating studs for stallions, whereas length of neck, cannon bone circumference and width of thorax were important for mares. Hintz et al (1979) proved Thoroughbred colts to be larger than fillies not only in their youth but also at further stages of development; the same was observed by Saastamoinen (1990) in his studies of the Finnhorse breed. Next, Kashiwamura et al (2001) in their studies of Banei draft racehorses observed the investigated parameters of the pelvis area to be greater in -Present address: ul.…”

Gender on the growth of Criollo foals from birth to three years of age

“…HINTZ et al (1979) reported similar differences in cannon bone perimeter between males and females of the Thoroughbred breed, observing that the average cannon bone perimeter at birth was greater for males and the growth curve differentiated from females over time, with the difference accentuated after one year of age. Despite the significant differences observed between males and females in relation to cannon bone perimeter, the differences may be barely noticeable biologically.…”

“…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).…”

Use of linear and non-linear functions to describe the growth of young sport- and race-horses born in Normandy

“…Although the growth rate slows down, there are no step changes and there is a steady progression in development. The uniformity of growth for most light horse breeds has been reported earlier (Hintz et al, 1979). The same author explains that large Draught horses apparently reach mature weights later than light horses, which could explain the relative slowest growth in SF (that have a small part of Draught horse genes) than in Tb or FT.…”

“…In another study (Ruff et al, 1993), foals diagnosed with cervical vertebral malformation tended to be heavier and taller at some time intervals in their first months of life than normal foals. It is recognised that growth can be easily influenced by the level of feed intake (Hintz et al, 1979), and it has been demonstrated on 36 New Forest filly foals that an imposed restricted nutrition between 6 and 12 months inhibited skeletal growth (Ellis and Lawrence, 1978). As a conclusion, most models are adapted for describing the growth curve of horses between 1 and 18 months.…”
