One of the breeding objectives for Shagya Arabian breed in Rădăuți Stud Farm, Romania, focuses on increasing the height at withers for mares. The current research aimed to study the entire female progeny (175 foals) of 58 broodmares and 44 stallions included in the breeding activity for 40 years The objective was to determine the influence of breeders' height and the foaling number (rank) on the foals' biometrics. The average value of this measurement in female foals has consistently increased from first foaling (157.63 cm) to the fifth one (158.80 cm) throughout 40 years of breeding, indicating the fulfilment of the breeding goal over consecutive reproductive seasons. According to the simulation based on the linear trend equation, the progeny's height at withers could match the fathers' height by the 10th foaling if the same breeding practices were continued. In addition, stallions would have much more influence than broodmares in increasing the height of the foals. Continuing the forecast analysis based on the variations, the required average height at withers values in stallions and mares can be computed to attain a certain value for the descendants.

The study involved the analysis of the mares included in the brood stock between 1989-2018 and the public breeding stallions registered in the ranking sheets ranged from 2000-2010 of the Shagya Arabian horse breed, from the Radauti Stud farm, Suceava county, Romania. The dynamics of the average values of height, heart girth, and cannon girth were studied for both breeders category, to follow the evolution of the breed within the stud. The average values of the female's height ranged from 156.7±0.069 cm to 159.9±0.102 cm; the average values for heart girth felt within the 180.1±0.151 cm - 180.8±0.153 cm interval; the average values of cannon girth varied between the 18.0±0.11 cm to 18.8±0.09 cm. The minimal value for height at withers in stallions was 157.66±1.21 cm while the maximal was 161.22±0.84 cm; average values of the hearth girth varied between 177.25±4.09 cm and 183.33±1.83 cm; cannon girth had average values of 18.5±0.77 - 19.16±0.31 cm. On the morphometric indices, it was found that stallions had higher values of massiveness index (113.21%) vs. mares (113.06%) and for the dactylo-thoracic index, as well (stallions had 11.11% and the mares 10.55%), while the bone index was higher in females (11.93%) vs. males (11.81%).

The paper presents the results of a study accomplished in the Rădăuți stud farm, which aimed to analyze some morphological and reproductive aspects of Shagya Arabian horses. The selected population was represented by broodmares from 2000y generation, introduced in the reproductive herd until now. The average value of height was 159.188 ± 0.593 cm, the average of heart girth was 177.188 ± 1.013 cm, and the cannon perimeter was 18,594 ± 0,184 cm for the studied horses. Regarding the reproduction aspects, it was revealed that the studied parameters had the following average values: 4.7 ± 0.3 years for age of introduction to reproduction, 4.5 ± 0.2 years for the age at first foaling, 338.7 ± 0.9 days for the gestation length, 149 ± 18.3 days for the service-period parameter, 503 ± 19.9 days for the foaling-interval parameter, and 14.6 ± 1.2 years for the reproductive longevity of broodmares. The conclusion was that all data obtained fall within the normal limits specified by the literature. [ABSTRACT FROM AUTHOR]

This study aimed to analyze 16 broodmares of Rădăuţi stud farm, from Dahoman, El-Sbaa, Koheilan, Shagya, and Siglavy-Bagdady genealogical lines, in terms of age at first foaling and age of introducing to breeding, as well as the reproductive parameter service-period. The results indicated that the age at first foaling, for the entire studied number of broodmares, had an average value of 2186.6±164.0 days, respectively 6.0±0.4 years; the absolute values were 1755 and 4200 days, respectively 4, 8, and 11.5 years, therefore, the variability of this character was high (28.1%). By removing from the calculations the broodmare Shagya LXII-3, which recorded the first mount after the age of 8 years, the mean was reduced to 2031.8±58.2 days (5.6±0.2 years), and the coefficient of variation for this character was reduced to 10.3%. Regarding the age of introducing to reproduction, we revealed that the average value was 1714.8±104.1 days (4.7±0.3 years), and the absolute values were 1242 and 3041 days (3.4–8.3 years); the group also showed high variability for this character (24.3%). As in the case of age at first foaling, if Shagya LXII-3 broodmare was excluded from the calculation, the mean is 1626.4±56.9 days (4.5±0.2 years) and the variability is reduced to 14%. The reproductive parameter service-period recorded the highest average value in case of the sixth foaling (235±90.4 days, with limits between 12-764 days) and the lowest after the eighth foaling (77.5±38.4 days, with limits between 11-221 days). The calculations indicated a very high variability of this character (98.3% in the third foaling-139.2% in the fourth foaling) showing that if the reproduction management of the Rădăuţi stud farm would suffer some changes, the final results regarding the reproductive activity of broodmares will be more favorable.

The present paper aimed to analyze 16 broodmares from the Rădăuţi stud farm (2000 generation), from the genealogical lines Dahoman (2 females), El-Sbaa (5 females), Koheilan (1 female), Shagya (4 female), and Siglavy-Bagdady (2 female); thus, we considered important to study reproductive parameters such as gestation, foaling interval and reproductive longevity of these broodmares. The results indicated that the average gestation length was 338.7±0.9 days, and the variability of this character was reduced (V%=2.7%). Regarding the average duration of each genealogical line, we observed that it ranged between 334.9±3.3 days (Dahoman) and 341±1.4 days (Shagya), both of them being in limits given by the literature; in this case, the coefficient of variability had values between 1.6% (Siglavy-Bagdady genealogical line) and 3.8% (Dahoman genealogical line), which indicates that the population is very homogeneous regarding this character. For the whole population, the foaling-interval parameter had an average value of 503±19.9 days, and the absolute values that ranged between 326 and 1125 days; the variability of this character was high (18.1 - 46.4%). Depending on the genealogical lines of broodmares, the average value of foaling-interval ranged from 423±31.4 days (Dahoman) to 613.8±63.7 days (Hadban). Regarding the reproductive longevity of the mares studied, we observed that the average value of this parameter was 5335.6±429.2 days, the minimum being 1995.0 days, and the maximum 7339.0 days. Depending on the genealogical line, the average values of reproductive longevity were between 4457 days/12.2 years (Dahoman genealogical line) and 6600.5 days/18.1 years (Siglavy- Bagdady genealogical line).

The paper was based on analyzing 119 Shagya Arabian mares (Dahoman, El-Sbaa, Gazal, Hadban, Koheilan, Mersuch, Shagya and Siglavy-Bagdady bloodlines), reared in Rădăuşi stud farm, between 1996-2016 years regarding fecundity percent, gestation length, abortion rate and foaling-interval parameters. The main purpose was to establish if the reproduction indices registered at females taken into study respect the limits indicated by the literature which can establish if the population can be included into the breeds' standard; the results showed that the fecundity percent had lower values than the literature describes and the foaling-interval exceeded the limits given by the literature, facts that reveal some aspects related to the reproduction process need to be reconsidered.
