The Finnish mating records of Standardbred trotters (SB; n = 33 679) and Finnhorses (FH; n = 32 731) were analysed to study the effect of the level of inbreeding on foaling rates and to estimate the heritability of foaling rate. A linear mixed model was assumed, with the outcome of the foaling (foal or no foal) as the trait of the study. A restricted maximum likelihood-based method was used to ...

BACKGROUND The major horse breeds in Finland are the Finnhorse (FH) and the American Standardbred (SB). The foaling rates of the FH have consistently been lower than those of the SB. During the last years, a decreasing trend in foaling rates of both breeds has been observed. The purpose of this study was to describe and compare the structure of these two mare populations for age, reproductive h...

The purpose of this study was to evaluate foaling rates of mares that were rebred after the pregnancy loss in same reproductive season and to examine factors influencing them in Hidaka, Japan. The study included 82 Thoroughbred mares that had experienced pregnancy loss. The foaling rate of the mares that were rebred after pregnancy loss was 57.3%. The foaling rate decreased as the period until ...

This study investigated some aspects of breeding management in the Italian Heavy Draught Horse breed, aiming at improving its efficiency at stud farm level. A first aim was to evaluate the risk of unsuccessful reproduction in mares after an early (3 years) or normal (4 years) age at first foaling, in interaction with different stud rearing systems. A second objective was the examination of the ...

Endometritis is an important cause of sub-fertility in mares. The critical indicator of reproductive success and financial return for commercial studs is live foaling rate. Endometrial bacteriology and/or cytology are used to diagnose endometritis and thus identify mares at risk of early embryonic death. However, mares with endometritis may conceive but then abort in late gestation. The aims of...

In humans and animals there is a popular belief that spontaneous parturition, therefore pregnancy length, could be influenced by the lunar cycle, but results from are often impaired multiple variables of studied population. domestic those problems can limited studying restricted population, such as single breed, reared under uniform conditions. The present study aimed to assess possible influen...

With the goal of characterizing the type and degree of injuries and blemishes incurred by horses living under natural social conditions, all members of a semi-feral herd of ponies were inspected on 4 occasions over a period of 28 months. Two occasions were during breeding/foaling season and 2 during non–breeding/foaling season months. On each occasion, each animal was examined (N = 47–65) and a...

ABSTRACT The objective of this study was to determine pH and the concentrations Calcium (Ca2+), Magnesium (Mg2+), Chloride (Cl-), Sodium (Na+), Potassium (K+) (Ca2+) in mammary gland secretion pre-foaling Mangalarga Marchador (MM) mares best method predict parturition breed. Forty-two pregnant MM were evaluated once daily from 310 days gestation until parturition. Mammary pH, measured by meter ...

Case Description- A 6-year-old mare suffering from uterine prolapsed was presented to the veterinary clinic. The uterus was prolapsed 4 hours following a normal foaling. Clinical Findings- Initial evaluations of the uterus revealed that prolapsed part of uterus (about 60 centimeters) was congested but its endometrial tissue was seen viable. ...

The changes in antioxidant components in the blood of ten cold blood mares during pregnancy and after foaling were investigated. Mares' blood samples were collected three times: at the 6th month of pregnancy, two weeks before delivery and four weeks after foaling. The activity of superoxide dismutase, glutathione peroxidase, total antioxidant status (TAS), total bilirubin and uric acid were mea...
